Abstract:
Objective: To identify the barriers and facilitators in the identification and management of high-risk pregnancies in India. Methods: A systematic search of PubMed and Google Scholar was conducted from the inception of database till 27 March 2024, using predefined keywords and search terms, including “high risk pregnancy,” “identification,” “management,” “barrier,” “challenge,” “facilitator,” “enabler,” and “India,” combined using Boolean operators (AND/OR). Only studies published in English were included. Screening was conducted using Rayyan software. Data were extracted into structured tables and synthesized using a qualitative thematic approach to identify key barriers and facilitators in the identification and management of high-risk pregnancies. Results: A total of 144 publications were identified. After screening based on eligibility criteria, 21 studies were finally included in the review. The included studies highlighted multiple barriers in the identification and management of high-risk pregnancies, including knowledge and awareness gaps among women and healthcare providers, inconsistent clinical management, and inadequate infrastructure. Financial constraints and cultural factors further added to the challenges. Women in tribal and rural areas faced additional barriers such as geographical isolation, lack of transportation, and limited access to specialized maternal healthcare. Facilitators identified in the literature included social support networks, the role of community health workers in bridging gaps between facilities and communities, and targeted education programs. Improved health literacy, standardized clinical protocols, and tailored management strategies were also reported as important facilitators. Conclusions: This review highlights the importance of strengthening healthcare infrastructure and addressing the identified barriers comprehensively to improve maternal and fetal outcomes. Enhancing awareness, empowering community health workers, and adopting standardized management protocols can contribute significantly to better identification and management of high-risk pregnancies in India.

Abstract:
Objective: To estimate the pooled prevalence rate of different types of abortion and the most important related factors of abortion in Iran based on a systematic review and meta-analysis. Methods: This systematic review and meta-analysis was conducted on the Iranian studies during the February 1, 2012 to December 31, 2024. Abortion prevalence and its influencing factors were evaluated. Relevant keywords were used to find eligible studies in Web of Science, PubMed, Google Scholar, Scopus, Science-Direct and SID databases. Due to high heterogeneity in included studies, random-effects model was utilized to estimate the pooled estimated of abortion and its subgroups. Results: Out of 231 reviewed articles, only 11 articles on 24 429 women were finally included. The pooled prevalence of induced abortion, spontaneous abortion, legal abortion and overall abortion was estimated as 7.65% (95% CI 4.24 to 11.95), 5.92% (95% CI 0.24 to 18.32), 1.66% (95% CI 0.83 to 2.76) and 7.23% (95% CI 1.07 to 18.22), respectively. Conclusions: Abortion is a worldwide major public health problem even in Iran and related to different socioeconomic and psychosocial factors. Its prevalence in Iran is high and it remains as reproductive health concern in Iran due to low fertility rate and oncoming up down population growth.

Abstract:
Objective:To evaluate the efficacy of platelet-rich plasma (PRP) incubation on embryo developmental outcomes in intracytoplasmic sperm injection (ICSI) cycles involving low-quality sperm. Methods: Sixty-six couples undergoing ICSI were enrolled in a prospective randomised study conducted at Halim Fertility Center, Indonesia between January and August 2023. Male with severe oligoasthenoteratozoospermia were randomised into two groups. Following density gradient centrifugation, samples in the PRP group were incubated with autologous PRP for one hour prior to ICSI, whereas the non-PRP group underwent standard processing without PRP exposure. Baseline characteristics and assisted reproductive technology outcomes between two groups were compared. The primary outcome was the blastocyst formation rate, while secondary outcomes included fertilisation rate, cleavage rate, and blastocyst quality. Results: A total of 66 couples were included, with 33 couples in each group. Participants' demographics and semen parameters did not differ significantly between the two groups. The PRP group demonstrated a higher fertilisation rate than the non-PRP group (84.1% vs. 78.2%), but the difference was not statistically significant (P=0.38). The PRP group showed significantly higher cleavage rates (98.9% vs.95.0%; P=0.03) and blastocyst formation rates (56.7% vs. 46.6%; P=0.006) compared to the non-PRP group. Additionally, the PRP group exhibited a higher proportion of good-quality blastocysts (44.8% vs. 41.2%; P=0.01) and a lower proportion of poor-quality blastocysts (22.1% vs. 27.8%; P=0.03). Conclusions: PRP incubation prior to ICSI in severe oligoasthenoteratozoospermia cases improves cleavage rates, blastocyst formation, and embryo quality. PRP may be a promising adjunct to optimise ICSI outcomes in male factor infertility. Study registration: This study was registered at ClinicalTrials.gov with the registration number NCT07579858.

Abstract:
Objective: To compare pregnancy outcomes between a hyaluronic acid (HA)-enriched transfer medium and a conventional HA-free transfer medium in frozen embryo transfer cycles. Methods: We conducted a retrospective cohort study at Hung Vuong Hospital including frozen embryo transfer (FET) cycles performed between May 2023 and February 2025. Cycles were classified according to the transfer medium used: HA-enriched EmbryoGlue (EG) versus Continuous Single Culture-NX Complete (CSCM-NXC). Outcomes included positive human chorionic gonadotropin (hCG), clinical pregnancy, ongoing pregnancy, live birth, and pregnancy loss. Results: A total of 840 FET cycles were analyzed (EG, n=445; CSCM-NXC, n=395). Pregnancy outcomes were comparable between groups. Use of EG was not associated with higher rates of positive hCG (40.67% vs. 41.77%) or live birth (27.87% vs. 28.86%). Adjusted analyses similarly showed that transfer medium type was not associated with positive hCG [adjusted odds ratios (aOR) 0.92, 95% CI 0.69-1.22] or live birth (aOR 0.92, 95% CI 0.67-1.25). Conclusions: In this retrospective cohort, use of an HA-enriched transfer medium was not associated with improved pregnancy outcomes in FET cycles.

Abstract:
Tumour necrosis factor alpha (TNF-α), a pleiotropic pro- inflammatory cytokine, plays a crucial role in orchestrating immune responses at the maternal-foetal interface. Excessive TNF-α expression can result in compromised implantation, defective placentation, and ultimately miscarriage. Moreover, TNF-α stimulates the release of other inflammatory mediators, creating a feedback loop that exacerbates tissue damage. Despite these insights, limited studies have evaluated TNF-α levels in early pregnancy as a predictive marker in Indonesian populations, particularly in Aceh. Thus, this research aims to explore the relationship between first- trimester TNF-α levels and miscarriage, offering potential clinical utility in early pregnancy risk assessment. We conclude that elevated serum TNF-α levels in the first trimester are significantly associated with miscarriage. TNF-α may serve as a potential biomarker for predicting adverse pregnancy outcomes and could inform preventive strategies in antenatal care. Larger, multi- centre studies incorporating broader immunological markers are recommended to confirm these findings.

Abstract:
Objective: To identify barriers and future strategies for establishing fertility preservation in developing countries. Methods: A systematic literature search was conducted to identify studies/articles reporting in English on the barriers and strategies of fertility preservation in the developing countries. The literature search was conducted in PubMed, Cochrane Library, Scopus, and Google Scholar using search terms "challenges", "strategies", "fertility preservation", and "developing countries" to identify relevant sources from 2019 to 2024 applicable to current updates on fertility preservation. Results: A total of 34 studies were included in the analysis. Barriers were identified on healthcare providers and patients. Moreover, it could also be categorized as the backbone of an established fertility preservation center, which is an accessible assisted reproductive technology (ART) center. Without an established ART center, maintaining and utilizing the fertility preservation center would be challenging. Lack of awareness was another main barrier identified among healthcare providers. From the patient's perspective, the main barriers identified were the lack of financial support for fertility preservation programs and the awareness of fertility preservation programs. Policy, sociocultural, religious, knowledge, access to service, competency, and attitude were the other barriers identified. Few studies addressed strategies. Several strategies were identified, including improving access to ART facilities, enhancing financial support and policy for targeted patients undergoing fertility preservation, and increasing knowledge and awareness of healthcare providers and patients. However, further investigation is warranted. Conclusions: Several barriers have been identified for fertility preservation in developing countries. Therefore, corresponding strategies were proposed to specifically address them.

Abstract:
Objective: To investigate ameliorative effects of Vitex agnus-castus (VAC) and VAC containing pharmaceutical supplement (VPS) against polycystic ovary syndrome (PCOS). Methods: PCOS in the rats was induced by daily administration of letrozole at 1 mg/kg body weight concentration for 21 d. PCOS rats were then treated daily either with metformin, VAC plant extract or VPS at 70, 8 or 8 mg/kg body weight concentration for 15 d. Rats that received none of these treatments were considered as control. Blood and ovaries were collected from all the rats. Serum glucose, cholesterol, triglyceride and high density lipoprotein-cholesterol were measured spectrophotometrically. Serum insulin, estrogen, progesterone, testosterone, luteinizing hormone, follicle-stimulation hormone, catalase, superoxide dismutase, malondialdehide and reduced glutathione were measured using enzyme-linked immunosorbent assay. Results: Rats treated with letrozole demonstrated a significant increase in serum testosterone, estrogen, cholesterol, luteinizing hormone, triglycerides, glucose, insulin, and malondialdehide levels, and a significant decline in progesterone, follicle-stimulating hormone, high density lipoprotein-cholesterol, catalase and reduced glutathione levels compared to control. Contrarily, no significant change in superoxide dismutase was noted in response to letrozole treatment. Rats treated with metformin, VAC or VPS showed a remarkable reversal in the levels of parameters affected by letrozole treatment. Conclusions: Data indicate that VAC and VPS exert potential ameliorative effects against PCOS through the modulation of hormonal and lipid profile as well as oxidative stress. Moreover, the favorable effects of these compounds are comparable to that of metformin.

Abstract:
Objective: To study the effects of co-administration of Gynura procumbens (GP) and kelulut honey (KH) on male fertility and libido in diabetes-induced rats. Methods: A total 42 males Sprague Dawley rats aged 8 weeks were randomly and equally divided into six different groups. All groups except a normal control group were induced with 50 mg/kg of streptozotocin (STZ) intravenously to induce diabetes. A positive control group was treated with an antidiabetic drug, metformin (500 mg/kg) whereas a negative control group remained untreated throughout the experiment. Meanwhile, another three treatments on diabetic rat groups were performed and categorised as Group 1 (450 mg/kg GP + 300 mg/kg KH), Group 2 (450 mg/kg GP + 600 mg/kg KH) and Group 3 (450 mg/kg GP + 1 200 mg/kg KH). Treatments were given for seven consecutive days through oral gavage and all rats were euthanized on day 8th for fasting blood glucose analysis, sperm quality, spermatogenesis, sexual behaviour and implantation sites analysis. Results: Fasting blood glucose levels were significantly reduced after treatment of GP and KH, compared to negative and positive controls. The treated groups showed significant increment in sperm quality compared to all control groups. Testes histology illustrated significant damages on leydig and sertoli cells for both negative and positive controls. On the contrary, co-administration of GP and KH displayed regeneration of leydig and sertoli cells in the testes. Additionally, the number of implantation sites significantly increased in females copulated with treated groups, compared to controls. Besides, the libido analysis displayed improvement of libido in treated groups, compared to all controls. Throughout the study, insignificant variances were recorded between the treated groups, indicating that treatment in Group 1 was sufficient to trigger significant improvement on fasting blood glucose level, fertility, and libido in diabetic male rats. Conclusions: Co-administration of GP and KH has great potential to serve as a pro-fertility agent amongst diabetic patients.

Objective: To evaluate effect of Phaseolus vulgaris (P. vulgaris) on the breastfeeding in female rats. Methods: This experimental study was done from May 2018 to December 2018 in the Anatomical Department of Medical School in Kermanshah University of Medical Sciences in Iran. In this study, after one-week adaptation and fertilization by male, 40 female rats within 20 days of pregnancy (on average, every mother had 10 newborns) were equally separated into four groups (animals were administrated after delivery of offspring). Group 1 was control group receiving normal saline interaperitoneally, and groups 2, 3, 4 were treatment groups receiving the dose of 20, 50, 100 mg/kg of P. vulgaris interaperitoneally respectively once a day for 60 days. The prolactin hormone was measured by radio immune assay, number and diameter of alveoli via histological and morphometrical examinations, and receptor prolactin gene expression by real-time polymerase chain reaction method. Results: P. vulgaris significantly improved alveoli’s number and diameter, prolactin hormone and receptor prolactin expression when compared to the control group (P<0.001). Conclusions: P. vulgaris is helpful to improve the breastfeeding parameters of rats’ mammary glands.

Abstract:
Objective: To investigate the effect of different fractions from the aqueous methanolic root bark of Adansonia digitata (Linn) on the estrous cycle of female Wistar rats and to elucidate their phytochemical content. Methods: Crude aqueous methanol extract of Adansonia digitata (Linn) root bark was fractionated by column chromatography using various ratios of hexane, acetyl acetate, methanol and distilled water. Fractions with similar trails on a thin layer chromatography were pooled into four fractions. Each fraction was then screened for its phytochemical content. Forty mature Wistar female rats weighing (135±28) g with regular estrous cycles were given each fraction at two dose levels while a control group received distilled water of equal volume. Treatments were given per os for 15 days starting from the day of estrus. Vaginal smears were observed daily for the duration of each cycle, frequency of occurrence of each stage of the estrous cycle and number of cycles for 15 days before and during treatment. At the end of treatment, rats were humanely sacrificed. Ovaries and uteri were weighed and processed for histopathology. Results: Hexane acetyl acetate and acetyl acetate methanol fractions at 150 mg/kg body weight and 300 mg/kg body weight prolonged the occurrence of proestrus and diestrus and produced atretic cyst-like ovaries at 300 mg/kg body weight. Acetyl acetate methanol treated rats also had low relative ovarian weights when compared to the control. Conclusions: Sterols and triterpenes in hexane acetyl acetate and acetyl acetate methanol fractions of the root bark may be responsible for the disruption of estrous cycle in female Wistar rats and may have a contraceptive effect.
Objective: To investigate the effect of different fractions from the aqueous methanolic root bark of Adansonia digitata (Linn) on the estrous cycle of female Wistar rats and to elucidate their phytochemical content. Methods: Crude aqueous methanol extract of Adansonia digitata (Linn) root bark was fractionated by column chromatography using various ratios of hexane, acetyl acetate, methanol and distilled water. Fractions with similar trails on a thin layer chromatography were pooled into four fractions. Each fraction was then screened for its phytochemical content. Forty mature Wistar female rats weighing (135±28) g with regular estrous cycles were given each fraction at two dose levels while a control group received distilled water of equal volume. Treatments were given per os for 15 days starting from the day of estrus. Vaginal smears were observed daily for the duration of each cycle, frequency of occurrence of each stage of the estrous cycle and number of cycles for 15 days before and during treatment. At the end of treatment, rats were humanely sacrificed. Ovaries and uteri were weighed and processed for histopathology. Results: Hexane acetyl acetate and acetyl acetate methanol fractions at 150 mg/kg body weight and 300 mg/kg body weight prolonged the occurrence of proestrus and diestrus and produced atretic cyst-like ovaries at 300 mg/kg body weight. Acetyl acetate methanol treated rats also had low relative ovarian weights when compared to the control. Conclusions: Sterols and triterpenes in hexane acetyl acetate and acetyl acetate methanol fractions of the root bark may be responsible for the disruption of estrous cycle in female Wistar rats and may have a contraceptive effect.

Abstract:
Objective: To compare the levels of p38 mitogen-activated protein kinase (MAPK), soluble endoglin and endothelin-1 in the serum of patients with severe preeclampsia, hemolysis, elevated liver enzymes, and low platelets (HELLP) syndrome and normal pregnancies. Methods: This study was an observational analytic cross-sectional study performed at Wahidin Sudirohusodo Hospital, Makassar, Indonesia, in the period of 5th February 2016 to 20th January 2017. P38 MAPK, soluble endoglin and endothelin-1 levels of patients with normal pregnancies, severe preeclampsia and HELLP syndrome were measured by enzymelinked immunoabsorbentassay technique, using kits of human soluble endoglin, endothelin-1 and p38 MAPK, Quantikine immunoassay: R&D System Inc. Results: Level of serum p38 MAPK in HELLP syndrome group was higher than in severe preeclampsia and normal pregnancy groups. Soluble endoglin and endothelin-1 levels in pregnancies with severe preeclampsia and HELLP syndrome were higher than normal pregnancy but there was no significant difference between these two groups (P>0.05). Levels of p38 MAPK, soluble endoglin and endothelin-1 also had a positive linear correlation with systolic and diastolic blood pressures (P<0.05). Conclusions: P38 MAPK in serum may be a marker for evidence of the severe hypoxia and its application may be considered for the diagnosis of HELLP syndrome.

Abstract:
Pyometra is one of the most important and common disorders in canine. The disease results in life threatening condition associated with septicemia and toxemia. The condition commonly occurs during luteal phase of estrous cycle, generally 4 weeks to 4 months of estrous cycle. The age, parity, breeds, administration of hormones are some predisposing factors of the condition. However, interaction between potentially pathogenic bacteria and hormonally primed uterus is believed to result in pyometra. The disease is initiated in the form of cystic endometrial hyperplasia, which later progresses into purulent uterine content fo llowing bacterial infection resulting in pyometra. The disturbance in antioxidant and prooxidant balance succeeding bacterial infection results in oxidative stress. The resultant stress further induces endometrial degeneration, immunosuppression and additionally aggravates the condition. An important clinical sign is malodorous, sanguineous or mucopurulent vaginal discharge with general symptoms such as vomiting, polyuria, polydipsia, depression, anorexia and occasionally fever. Till date, ultrasonography is the best diagnostic method while radiology and serological test are also helpful. Recently, the estimation of inflammatory mediators (acute phase proteins and prostaglandin metabolites) has appeared as marker for diagnosis of the pyometra. Determination of levels of inflammatory mediators has emerged as an important diagnostic method because it can be helpful in prognosis of the condition. The pyometra can be best treated by surgical manipulation (ovariohysterectomy);however, hormonal treatment can be given in less severe cases which aimed at reducing the effect of progesterone on the reproductive tract. Together, provision of antioxidants could be helpful in disease recovery along with the determined treatment. In this review, incidence,predisposing factors, etio-pathogenesis, oxidative stress associated with condition, diagnostic methods and treatment are discussed.

Abstract:
Among resources of mesenchymal stem cells, human umbilical cord appears to be a rising source capable of differentiating into all germ layers, reaching and repairing lesion areas, and promoting wound repair, and it has also the capacity to influence the immune response. Human umbilical cord-derived mesenchymal stem cells are considered to be an optimal resource compared with other mesenchymal stem cells sources because they require a noninvasive recovery. All these characteristics allow their use in heterogeneous applications. Human umbilical cord-derived mesenchymal stem cells can regenerate tissues, stimulate angiogenesis, modulate inflammatory pathway signals and recruit endogenous stem cell. Human umbilical cord-derived mesenchymal stem cells suppress mitogen-induced signals and modulate the activation and proliferation of several immune cells, modifying lymphocyte phenotypes activity. In culture, human umbilical cord-derived mesenchymal stem cellss show the capacity to create several tissues such as bone, cartilage, and fat. Human umbilical cord-derived mesenchymal stem cells can be isolated from the different compartments of umbilical cord and processed by using different techniques. Clinical applications of human umbilical cord-derived mesenchymal stem cells include graft-versus-host disease, autoimmune diseases such as Sj.gren's syndrome and diabetes mellitus types 1 and 2, gynecological disorders like endometriosis. Recent studies have shown possible application on rheumatoid arthritis, osteoarthritis, and neuronal degenerative diseases. This review is focused on the resources, molecular profiles, propriety, in vitro characterizations, clinical applications and possible future usage of human umbilical cord-derived mesenchymal stem cells.

Abstract:
Objective: To investigate ameliorative effects of Vitex agnus-castus (VAC) and VAC containing pharmaceutical supplement (VPS) against polycystic ovary syndrome (PCOS). Methods: PCOS in the rats was induced by daily administration of letrozole at 1 mg/kg body weight concentration for 21 d. PCOS rats were then treated daily either with metformin, VAC plant extract or VPS at 70, 8 or 8 mg/kg body weight concentration for 15 d. Rats that received none of these treatments were considered as control. Blood and ovaries were collected from all the rats. Serum glucose, cholesterol, triglyceride and high density lipoprotein-cholesterol were measured spectrophotometrically. Serum insulin, estrogen, progesterone, testosterone, luteinizing hormone, follicle-stimulation hormone, catalase, superoxide dismutase, malondialdehide and reduced glutathione were measured using enzyme-linked immunosorbent assay. Results: Rats treated with letrozole demonstrated a significant increase in serum testosterone, estrogen, cholesterol, luteinizing hormone, triglycerides, glucose, insulin, and malondialdehide levels, and a significant decline in progesterone, follicle-stimulating hormone, high density lipoprotein-cholesterol, catalase and reduced glutathione levels compared to control. Contrarily, no significant change in superoxide dismutase was noted in response to letrozole treatment. Rats treated with metformin, VAC or VPS showed a remarkable reversal in the levels of parameters affected by letrozole treatment. Conclusions: Data indicate that VAC and VPS exert potential ameliorative effects against PCOS through the modulation of hormonal and lipid profile as well as oxidative stress. Moreover, the favorable effects of these compounds are comparable to that of metformin.

Abstract:
Objective: To determine the effect of different cervical dilators on cervical dilation and reproductive performance of fat-tailed ewes. Methods: In experiment 1 140 ewes were divided into seven groups with seven different treatments as following: 10 mL normal saline (control group), 100 IU oxytocin (OT group), 100 μg estradiol and 100 IU oxytocin (E2+OT group), 5 mL relaxin (R group), 2 mL sensiblex (SEN group), 200 μg misoprostol (MIS group) or 200 μg dinoprostone (DIN group). In experiment 2, artificial insemination was applied for evaluation of reproductive performance in experimental groups. Results: In experiment 1, the highest cervical dilation was observed in OT (90%) and E2+OT (100%) groups (P<0.05), while no significant differences was found among DIN, MIS, SEN and R groups (80%, 75%, 70% and 65%, respectively). In addition, the lowest cervical dilation was observed in control group. Experiment 2 found no significant differences among control, OT and E2+OT groups. The highest pregnancy rate, parturition rate and lambing rate were observed in OT groups (60%, 60% and 70%, respectively) and E2+OT groups (65%, 60% and 70%, respectively) compared to SEN, R, MIS and DIN groups (P<0.05). Conclusions: Oxytocin treatment alone or with estradiol could be used as a suitable dilator for improving reproductive efficiency during artificial insemination in fat-tailed ewes.

Abstract:
Objective: To study the methods of increasing the reproductive qualities and indices of viability in the offspring of Holstein cows under conditions of intensive milk production. Methods: Studies were conducted on 3 groups of Holstein cows with 30 heads in each group. Animals of the experimental groups had a different length physiological period. The study focused on experimental groups of animals: the reproductive indicators, the viability of newborn calves, and their growth rate. All the digital materials of the experimental data were processed by the method of variation statistics for the significance of the difference of the compared parameters using the Student’s criterion, adopted in biology and zootechnics. Results: Studies found that reduction of the duration of the service period, along with a simultaneous increase in the inter-lactation period to 80–90 days, increased the reproductive capacity of the cows, and enhances the viability of the offspring compared with their peers. Conclusions: The study revealed the optimal duration of the physiological periods in highproducing cows under conditions of intensive milk production technology.

Abstract:
Objective: To assess the secondary sex ratio (SSR) of assisted reproduction technology babieswithin a fertility clinic in Melbourne, Australia.Methods: A retrospective cohort study was conducted on 3 369 babies who were born following single embryo transfer between 2011 and 2016. Variables examined included embryo creation date, maternal and paternal ages, maternal body mass index (BMI), type of infertility,sperm parameters, fertilization method, type of embryo and stage of transfer. Multivariate regression analysis was performed on the data set using STRATA V9.2. Results: More males were found to be born to embryos created in summer (adjusted odds ratio=1.46, 95% confidence interval: 1.08-1.95; P=0.01). Lower BMI of mother (30 kg/m2)and younger age of parents (35 years) were associated with an increase in SSR (50.1% vs.47.1%; 50.6% vs. 48.8%; 50.0% vs. 48.9%) respectively. Decreased SSR value was associated with primary subfertility, using in-vitro fertilization procedure and fresh embryo compared to those with secondary subfertility, using intracytoplasmic sperm injection procedure and thawed embryo (49.3% vs. 50.6%; 47.1% vs. 50.8%; 49.4% vs. 50.1%) respectively.Conclusions: The fertilization methods, type of embryo, stage of embryo transfer, parameters of the sperm and status of subfertility do not significantly affect the SSR. SSR is affected by the seasonality, maternal age, and BMI.

Abstract:
This article presents a review pertains the laser irradiation effects and its possible mechanisms of action on spermatozoa functions in domestic animals. To improve artificial insemination, laser is sensitive and cost effective technique, when compared to other conventional methods. Laser may have both positive and negative effects on spermatozoa functions. Since the effects of light are mediated by reactive oxygen species, and the levels of these reactive oxygen species following irradiating spermatozoa with laser may be responsible for determining the effects of laser on sperm. Dose of laser may be regarded as of great significance and this dosage of laser may be responsible for determining its effects on spermatozoa. Optimum dosage of laser for improving seminal attributes may vary among various species and this need to be standardized in each of them. The beneficial effects include improving sperm livability, acrosomal integrity, hypo-osmotic swelling response, mitochondrial function and computer-aided sperm analysis parameters. The increase in cytochrome c oxidase activity, ATP levels and mitochondrial membrane potential, in laser irradiated cells may be responsible for enhanced sperm quality parameters. Improving fertility with laser irradiated spermatozoa has been reported in few species like boar and need to be elaborated in other species. In conclusion laser may be regarded as an easy, cheap and time saving technology for improving artificial insemination; in addition, laser may have various potential applications in the field of reproductive biotechnology as well as in livestock farms and veterinary polyclinics.

Kaki enriched extender (KEE) was prepared by adding to TCF in concentrations 0.0/5.0 mL (control, 0%), 0.5/4.5 mL (1%), 1/4 mL (2%), 1.5/3.5 mL (3%), 2.0/3.0 mL (4%), 2.5/2.5 mL (5%), 3.0/2.0 mL (6%), 3.5/1.5 mL (7%), 4.0/1.0 mL (8%), 4.5/0.5 mL (9%) and 5.0/0.0 mL (10%) to obtain a final volume 5 mL in each tube. Whole egg yolk was added to each tube to obtain KEE with 20% egg yolk (KEEY), all tubes were centrifuged to get rid of debris. Semen was added to the supernatants in other tubes. Extended semen was subjected to evaluation [motility, alive sperm and intact sperm membrane (HOST) %] in both chilled and cryopreserved semen. Conception rate was carried out. Results: Sperm motility was significantly (P<0.000 1) kept high after 11 d of chilling with the concentration 1%, 2%, 3%, 4%, 5% as compared to the control (41.67±1.67, 41.67±1.67, 40.00±0.00, 41.67±1.67 and 41.67±1.67, respectively) and also non-significantly kept high at the other concentrations up to 9 d of chilling. Addition of KEE had significantly(P<0.003 3) improved post thawing sperm motility % with the concentrations 1, 2, 3, 4, 5 and 6% as compared to the control (51.67±5.27, 55.00±3.16, 48.33±1.05, 45.00±3.96, 57.00±2.50,55.00±5.00 and 43.33±5.11 respectively).While the other concentrations exhibit no effect.Addition of KEE maintained alive sperm%, abnormalities% and % of intact spermatozoa membranes (HOST%) as good as the control with all concentrations of kaki used in our study.The conception rate upon using frozen semen in insemination showed higher conception rate in concentrations of 2%, 4% and 6 % KEE in cattle. Conclusion: It could be concluded that some concentrations of Diospyros kaki improved bull semen quality post-chilling and post-freezing.

Abstract:
Objective: To determine the effect of preparation to play a maternal role in mothers fertilized through in vitro fertilization on maternal anxiety. Methods: A total of 60 mothers undergoing in vitro fertilization were assigned into intervention group and control group. Pregnancy concerns and stress questionnaires were research tools. Questionnaires were completed in both groups before organizing preparation program. Then, the preparation program was held for four sessions for the mothers in the intervention group, and the subjects in both groups were immediately investigated again after completion of preparation program and one month later. Data analyses about pregnancy stress and concerns of mothers and its dimensions were performed by repeated measure (analysis of variance), Mann-Whitney, Friedman and Wilcoxon tests. Analysis of demographic variables was performed by using independent t-test and Chi-square test in SPSS 21. Results: The score of pregnancy stress and concerns before the intervention was not significantly different between the two groups. There was a significant difference in the intervention group in the score of pregnancy stress and concerns before and after the intervention (P<0.001), before and one month after the intervention (P<0.001), immediately after and one month after the intervention (P<0.001) which was not significant in the control group. Conclusions: Maternal preparation program can be effective in reducing maternal stress and concerns.

Abstract:
ObjectiveTo determine the effects of the water quality of Manila Bay on allometric parameters and histological biomarkers of selected organs of P. viridis. Methods Green mussels were collected from two coastal sites of Manila Bay, Las Piñas – Parañaque (LPP) and Bacoor, Cavite (BC). Twenty-four green mussels from each site were used for the assessment of allometric parameters, and six green mussels from LPP and eight from BC were used for the assessment of histological structures of gonads, gut, and digestive glands. Gonad development was categorized into five stages, whereas gut and digestive glands were scored into four categories. Results Allometric parameters that include shell height, weight, and total wet and dry soft tissue weight were significantly different between LPP and BC. It was also observed that exposure to the pollutants in Manila Bay resulted to delays in gonadal development, and detrimental changes and lesions in the histostructure of digestive gland and gut. Conclusions Pollutants in Manila Bay have detrimental effects to the growth, reproductive development, and histological structure of digestive organs of P. viridis.

Abstract:
Objective: To explore the effect of BHT on cattle spermatozoa during cooling and cryopreservation. Methods: Pooled bull semen were diluted by Tris-Citrate-Fructose egg yolk (TCFY) diluent considered as control (0 BHT) and different concentrations of BHT (1.0, 2.0, 3.0, 4.0, 5.0 and 6.0 mM were prepared in ethanol in prewarmed (37°C) test tubes. The ethanol was allowed to evaporate so that, a thin crystallized layer of BHT was deposited on the inner surface of the tubes. Then extended semen was added into the tubes and incubated at 37°C for 5 min to allow uptake of BHT by spermatozoa. The tubes were cooled slowly (approximately for 2 h) up to 5 and equilibrated for 4 h. After equilibration, semen freezing process was carried out. Extended semen was subjected to evaluation (motility, alive sperm, intact sperm membrane (HOST) % and acrosome integrity) in both cooled and cryopreserved semen. Results: The result revealed that sperm motility of post-cooled spermatozoa improved (P<0.05) by the use of BHT concentrations (1, 2 and 3 mM) in Tris semen extender if compared to the control (85.00±1.09), (83.33± 0.63), (81.67± 0.63) and (78.33± 0.63), respectively. Alive sperm percent was significantly higher in all concentrations of BHT. Sperm abnormalities percent were significantly lower in concentrations of BHT 1 and 2 (11.2±0.2), (11.8±0.2)and (13.4±0.4), respectively. Sperm membrane integrity were significantly higher in BHT concentrations (1, 2, 3, 4 and 5 mM). It is exhibited that improved sperm motility in post-thawed frozen semen in the concentrations of BHT (1, 2, 3 and 4 mM) if compared to the control. The sperm membrane integrity were significantly improved at all concentrations of BHT. Acrosome integrity was significantly higher at BHT concentration 1 mM (81.80±0.57) and (76.00±2.05), respectively. Conclusions: It could be concluded that some concentrations of BHT improved bull semen quality post-cooling and post-freezing.
