To investigate the role of vascular endothelial growth factor (VEGF)165a, VEGF165b, and VEGF receptor (VEGFR) in the development of bovine follicles. We cultured follicular cells that were collected from small, medium, and large sized bovine follicles with estrogen and measured the expression of VEGF, VEGFR2 and VEGF165b by Western blot analysis and immunofluorescence. The expression of VEGF165 increased in all follicle sizes and the expression of VEGF165b was increased in the small and large follicles after culturing in an estrogen containing medium. The expression of VEGFR2 was increased in the medium and large follicles after culturing with estrogen for 96 h. VEGF165 was activated at 100 ng/mL estrogen in the large follicles for 96 h. In addition, VEGFR2 was upregulated in the medium and large follicles after treated with 100 ng/mL estrogen for 96 h. This evidence suggests that the expression of VEGF165 and VEGFR is associated with estrogen stimulation during the development of bovine follicles and in an autocrine or paracrine manner. This reveals an advantage during oocyte maturation in vitro.

Growing evidence suggests that oxidative stress is a major cause of male infertility. Spermatozoa are highly sensitive cells due to the vulnerability of their membrane fatty acids and the diminished antioxidant defense. Reactive oxygen species (ROS) impact multiple signaling pathways involved in mitochondrial dysfunction, hormonal unbalance and semen quality decline. The origin of ROS is diverse, including generated normal cellular metabolism, environmental exposure, advanced paternal age and inflammation. Research has indicated that antioxidant supplementation can improve oxidative stress and reduce the risk of chronic diseases. Moreover, it is widely known that antioxidant supplementation can enhance sperm quality and increase the pregnancy rate in couples undergoing fertility treatments. The current study highlights the deleterious effect of ROS and its impact on semen function. In addition, it contributes to the development of a clinical approach for the use of antioxidants in the management of male infertility.

Objective: To determine whether a single dose of gonadotropin-releasing hormone (GnRH) agonist administered subcutaneously in addition to the regular progesterone supplementation could provide a better luteal support in antagonist protocol fresh embryo transfer cycles. Methods: This prospective, multicentric, cohort study included total 140 women, 70 in each group. Controlled ovarian stimulation was carried out as per fixed GnRH antagonist protocol. The trigger was given with hCG. In vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) was performed and day-3 embryos were transferred. Patients were divided into groups 1 and 2 based on computer generated randomization sheet. Six days following oocyte retrieval, group 1 received 0.2 mg decapeptyl subcutaneously in addition to regular progesterone support while group 2 received progesterone only. Luteal support was given for 14 days to both groups; if pregnancy was confirmed luteal support was continued till 12 weeks of gestation. The clinical pregnancy rate was the primary outcome. The implantation rate, miscarriage rate, live birth delivery rate, and multiple pregnancy rates were the secondary outcomes. Results: A total of 140 patients were analysed, 70 in each group. Clinical pregnancy rates (47.1% vs. 35.7%; P=0.17), implantation rates (23.4% vs. 18.1%, P=0.24), live birth delivery rates (41.4% vs. 27.1%, P=0.08), and multiple pregnancy rates (21.2% vs. 16.0%, P=0.74) were higher in group 1 than in group 2. Group 1 had a lower miscarriage rate than group 2 (5.7% vs. 8.6%; P=0.75). However, these differences were not statistically significant between the two groups. Conclusions: Administration of a single dose of GnRH agonist in addition to regular natural micronized vaginal progesterone as luteal support in GnRH antagonist protocol cycles marginally improves implantation rates, clinical pregnancy rates, and live birth delivery rates. However, more studies with higher sample sizes are needed before any conclusive statements about GnRH agonist as luteal phase support can be made.
目的:探讨单剂量促性腺激素释放激素(GnRH)激动剂在常规黄体酮补充的基础上皮下注射是否能在拮抗剂方案的新鲜胚胎移植周期中提供更好的黄体支持。方法:这项前瞻性、多中心、队列研究共纳入140名女性，每组70名。对照卵巢刺激按照固定GnRH拮抗剂方案进行。触发剂是hCG。进行体外受精/胞浆内单精子注射(IVF/ICSI)，移植第3天的胚胎。根据计算机生成的随机分组表将患者分为1组和2组。取卵6天后，组1在常规黄体酮支持的基础上皮下注射十肽0.2 mg，组2只注射黄体酮。两组均给予黄体支持14 d;如果确认怀孕，黄体支持持续到妊娠12周。临床妊娠率为主要观察指标。次要指标为着床率、流产率、活产率和多胎妊娠率。结果:共分析140例患者，每组70例。临床妊娠率(47.1% vs. 35.7%;P=0.17)、着床率(23.4% vs. 18.1%， P=0.24)、活产率(41.4% vs. 27.1%， P=0.08)、多胎妊娠率(21.2% vs. 16.0%， P=0.74)均高于组2。1组流产率低于2组(5.7%比8.6%;P = 0.75)。然而，这些差异在两组之间没有统计学意义。结论:在GnRH拮抗剂方案周期中，单剂量GnRH激动剂加常规天然微粉阴道孕酮作为黄体支持剂，可略微提高着床率、临床妊娠率和活产率。然而，在任何关于GnRH激动剂作为黄体期支持剂的结论性声明之前，需要更多样本量更大的研究。

Objective: To assess the potential of plantain-based diet in modulating testicular toxicities in rats exposed to atrazine. Methods: The plantain-based diet at 50%, 25% and 12.5% were prepared from the basal diet by substituting the corn starch with plantain fruit pulp flour at different percentages. Wistar rats were fed plantain-based diet in varying concentrations ranging from 12.5% to 50% of the basal diet for 21 days before or after atrazine treatment in a two-phase experiment: preventive and therapeutic phases. The therapeutic model (n=35) had seven groups with 5 rats each, including the control, atrazine, atrazine recovery, atrazine plus plantain-based diet 50%, 25%, 12.5%, and atrazine plus quercetin groups. The preventive model (n=30) had six groups of 5 rats, consisting of the control, atrazine, 50%, 25%, 12.5% plantain-based diet plus atrazine, and quercetin plus atrazine groups. Gonadal hormones (testosterone, luteinizing hormone and follicle-stimulating hormone), sperm parameters (sperm motility, viability, morphology and concentration), and testicular function indices (protein, cholesterol, glycogen, acid phosphatase, alkaline phosphatase and lactate dehydrogenase) were measured. Results: The gonadal hormones, sperm characteristics, and testicular function indices of the rat testis decreased significantly in the atrazine group alongside degeneration of the histoarchitecture. However, plantain-based diet restored the gonadal hormone concentrations, semen parameters, and testicular function indices in both the preventive and therapeutic models. Conclusions: Treatment with plantain-based diet protects against rat testicular toxicity caused by atrazine via the modulation of gonadal hormones, sperm quality, testicular function index as well as histoarchitecture of rat testes.

Objective: To determine the ovine ovarian histomorphology and follicular staging at various age periods in Awassi breed. Methods: Ovaries were collected from prenatal fetuses [gestational age (95±5) days], neonatal (day 0), and prepubertal ewe lambs (two and four months of age); each age group included six animals. Ovaries (n=12, each group) were dissected and processed for hematoxylin and eosin staining. Stained sections (n=24, each group) were imaged and utilized for histomorphology assessment, follicle measurement, and classification. Results: Prenatal ovaries were mainly enriched with primordial follicles accompanied by a lower proportion of primary follicles. In addition to primordial and primary follicles, neonatal ovaries demonstrated a proportion of centrally located multilayered and antral follicles. In comparison with neonatal ovaries, the proportion of multilayered and antral follicles was significantly higher in the ovaries of two-month-old lambs; conversely, the proportion of peripherally situated primordial follicles dramatically declined compared to that of earlier age of lamb. Although there was no statistical variation in the sizes of primordial follicles across groups, the mean diameter of the primary follicle in the prenatal ovaries was substantially smaller than in postnatal ovaries. Compared to the neonatal ovaries, the size of the multilayered and antral follicles in the prepubertal ovaries was substantially larger. Conclusions: The earliest follicular developmental stages were established prenatally whereas the advanced growth stages started in the neonatal period and greatly increased in the prepubertal period.

Objective: To determine the barriers of joining in-vitro fertilization (IVF) programs among infertile couples in developing countries. Methods: This study assessed infertile couples and the barriers or associated factors resulting in delayed decision-making of joining IVF program by searching databases PubMed, ScienceDirect, EBSCO, ClinicalKey, and Cochrane Library from inception until December 31, 2021. Additional search strategies were snowballing literature search and citation tracking. Results: Eleven articles were included in the scoping review. The cost was the greatest barrier of joining IVF program. Limited access and lack of assisted reproductive technology centers, few qualified infertility trained staff, insufficient government support, low priority in government policy, along with sociocultural factors, such as religion and false beliefs or myths were also majorly considered to be associated obstacles. Conclusions: The main barrier associated with IVF program among infertile couples in developing countries is the high cost of the IVF services.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection may have harmful effects on expectant moms, labor, and newborns born to infected mothers. There is a risk of the initiation of pregnancy with infection. Even if the gametes are non-infected, pregnancies could be exposed later for infection by coronavirus. Investigations of COVID-19 during pregnancy highlighted the non-transmission or surprising transmission of SARS-CoV-2 to the offspring. However, other studies have exhibited the potential mother-to-fetus transmission. In this way, unanswered concerns about SARS-CoV-2 fetal transmission and the particular interface(s) controlling its pathogenesis throughout pregnancy persist. This review focuses on the potential effects of SARS-CoV-2 on vertical transmission, as well as the influence of the virus on pregnancy and placenta.

Objective: To evaluate the effects of three oxidized palm oil diets (OPD) on female rat reproductive function. Methods: Forty-four female Wistar rats presenting five consecutive and regular estrous cycles were divided into 4 groups. The rats were fed with: a standard diet, 70% of standard diet+30% oxidized palm oil diet (OPD1), OPD1+5 g of boiled yolk egg (OPD2) and OPD1+10% sucrose (OPD3) for 125 days, respectively. During the feeding period, morphometric, estrous cycle, sexual behavior, gestation, biochemical and histomorphometric parameters were evaluated. Results: All OPDs significantly increased abdominal circumference, body mass index and Lee index coupled to an irregularity and lengthening of the estrous cycle. They significantly decreased appetite and consumption behaviours, quantic pregnancy index, fertility rate, implantation sites and index, serum progesterone and high-density lipoprotein levels, increased pre-implantation losses, anti-implantation activities, serum estradiol, triglycerides, total and low-density lipoprotein-cholesterol levels, and impaired brain and ovaries oxidative status. Histomorphometric examinations revealed increases in the number of atresic and primary follicles and decreases in secondary, tertiary, Degraaf, total and corpus luteum follicles in ovaries coupled to a neurodegeneration of hypothalamic anteroventral periventricular neurons in the OPD groups compared to the standard diet group. Conclusions: The three OPDs induce obesity and impair the female reproductive function, especially OPD2 and OPD3. These findings contribute to a better understanding of the adverse effects of palm oil bleaching on the reproductive function in female rats, which could be useful in the management of women with obesity-related sexual dysfunction.

Objective: To investigate the protective role of pumpkin seed ethanolic extract against escitalopram-induced reproductive toxicity in male mice. Methods: Swiss albino male mice were randomly divided into five groups with six mice in each group. Group I received normal water orally, Group II, III, IV and V received escitalopram oxalate (10 mg/kg), pumpkin seed extract (300 mg/kg) plus escitalopram oxalate (10 mg/kg), escitalopram oxalate (20 mg/kg), and pumpkin seed extract (300 mg/kg) plus escitalopram oxalate (20 mg/kg), respectively. All test doses were continuously administered orally once daily per animal body weight for 30 days and 60 days. Body weight and sexual organ weight were evaluated on day 31 and 61. Effects of pumpkin seed extract on sperm parameters, biochemical parameters and histology of testis were also investigated. Results: Escitalopram 10 or 20 mg/kg caused reproductive toxicity in male mice after 30 and 60 days of treatment. However, simultaneous administration of escitalopram oxalate (10 or 20 mg/kg) with pumpkin seed extract (300 mg/kg) attenuated escitalopram-induced testicular toxicity. Significant increase in the body weight and relative organ weight was observed. Sperm count, sperm motility and viability significantly increased (P<0.05). The histopathological alterations caused by escitalopram was also ameliorated. Conclusions: Ethanolic extract of pumpkin seeds (300 mg/kg body weight) protects again reproductive toxicity induced by escitalopram. Therefore, dietary intake of pumpkin seed extract might be useful for male patients who expose to antidepressant drug due to depression.

Objective: To elucidate the possible role of unfractionated heparin in patients with failed repeated in in vitro fertilization and embryo transfer (IVF-ET) and thrombophilia. Methods: This case control study evaluated the efficacy of the unfractionated heparin in increasing the pregnancy and implantation ratio in women with recurrent IVF-ET failures. Eighty-six women received in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) with a record of three or more previous IVF-ET failures. Participants were randomly distributed into two groups. Group A (n=43) received unfractionated heparin 5 000 IU twice daily, and group B (n=43) did not take any antithrombotic drugs. Coagulation abnormalities such as factor V Leiden (FVL) mutation, methylene tetra hydro folate reductase (MTHFR) mutation and prothrombin mutation (FII) were evaluated. Age, body mass index, basal follicular stimulating hormone, basal estradiol, duration of infertility, and number of IVF-ET failures were compared between two groups. Results: 45.0% and 17.4% of women were pregnant with and without MTHFR and prothrombin mutation, respectively, when they received unfractionated heparin treatment. The implantation rate was more in group A (12.5%) than group B (4.3%) and differences in the fertilization rate of the two groups were observed (27.7% vs. 35.9%). The clinical pregnancy rate per cycle was remarkably more in group A (30.2%) than group B (14.0%). Conclusions: Heparin is a safe and valuable treatment for patients with repeated IVF-ET failures. The clinical pregnancy and implantation rates are higher in the heparin-treated group in contrast with the control group. Trial registration: The trial registration was done with clinical registration number of “ IRCT138807202575N1”.
目的:探讨未分离肝素在体外受精和胚胎移植(IVF-ET)失败及血栓形成患者中的作用。方法:本病例对照研究评价未分级肝素对提高IVF-ET复发失败妇女妊娠和着床率的疗效。86名接受体外受精/胞浆内单精子注射(IVF/ICSI)的妇女有3次或3次以上IVF- et失败的记录。参与者被随机分为两组。A组(n=43)每日2次给予未分离肝素5 000 IU, B组(n=43)未服用任何抗血栓药物。评估凝血异常，如V - Leiden因子(FVL)突变、亚甲基四氢叶酸还原酶(MTHFR)突变和凝血酶原突变(FII)。比较两组患者的年龄、体重指数、基础卵泡刺激素、基础雌二醇、不孕持续时间和IVF-ET失败次数。结果:接受肝素单次治疗时，MTHFR和凝血酶原突变的孕妇分别占45.0%和17.4%。A组着床率(12.5%)高于B组(4.3%)，两组受精率差异(27.7% vs. 35.9%)。A组临床单周期妊娠率(30.2%)明显高于B组(14.0%)。结论:肝素对于反复IVF-ET失败患者是一种安全且有价值的治疗方法。肝素治疗组临床妊娠和着床率均高于对照组。试验注册:临床注册号为“IRCT138807202575N1”。
