To compare the effectiveness of inositol and metformin on the clinical characteristics, and endocrine and metabolic profiles of infertile polycystic ovarian syndrome (PCOS) women from Vietnam. From June 2018 to August 2022, a randomized trial was undertaken at the Hue Center for Endocrinology and Reproduction on infertile women aged 18 to 40 years with polycystic ovarian syndrome. The clinical, endocrine, and metabolic features of these individuals were assessed before and after 3 months of treatment with 2 g of inositol or 1700 mg of metformin per day. Natural pregnancy rates, adverse effects, and tolerance of inositol were recorded. The study included 171 infertile PCOS women who were eligible to participate and took part in the baseline assessment, of whom 132 women participated in data analysis after 3 months. After metformin treatment, 42.1% of women with oligomenorrhea experienced regular menstruation. Metformin significantly lowered body mass index (BMI), waist circumference and testosterone levels, but had no effect on other clinical characteristics, endocrine profiles, or metabolic profiles. 29.2% Of women reported experiencing side effects. 21% Of them attained pregnancy, which resulted in 17.1% of live births. In the inositol group, the rate of regular cycle increased by 18.2% and the total testosterone concentration significantly decreased. In overweight/obese women with PCOS, inositol significantly decreased weight, BMI, waist and hip circumferences (P<0.05). 100% Of women tolerated inositol and continued treatment. 18.9% Of them became pregnant, leading to 17% of live births. Metformin and inositol can improve weight and waist circumference in overweight/obese infertile women with PCOS. Metformin is associated with a higher rate of regular menstruation, whereas inositol is associated with a lower rate of adverse effects. The spontaneous conception, clinical pregnancy, and live birth rates between two groups are comparable.

To compare embryonic development, ploidy status and clinical outcomes between fresh and frozen-thawed oocytes. This retrospective cohort study evaluated 83 fertilization cycles including both fresh and frozen oocytes from 79 patients at the HP Fertility Center of Hai Phong International Hospital of Obstetrics and Pediatrics in Vietnam. The patient underwent several ovarian stimulation cycles to accumulate a certain number of oocytes that would be vitrified. In the last oocyte retrieval, all patient's oocytes including both frozen and fresh would be fertilized. The outcomes included the rates of oocyte survival, cleavage embryo, blastocyst, ploidy status, pregnancy, biochemical pregnancy and clinical pregnancy. The oocyte survival rate after thawing was 96.5%. No statistically significant difference was found when comparing fresh and frozen oocytes regarding fertilization rate (78.1% vs. 75.5%, P=0.461), usable cleavage embryo rate (86.9% vs. 87.2%, P=0.916) but usable blastocyst rate was found higher statistically in the frozen oocyte group (44.4% vs. 54.0%, P=0.049). The percentages of euploid, aneuploid and mosaic embryos between the fresh group and the vitrified group had no significant differences (33.8% vs. 31.6%, P=0.682; 51.0% vs. 54.2%, P=0.569; 15.2% vs. 12.4%, P=0.787; respectively). The rates of pregnancy, biochemical pregnancy and clinical pregnancy had no statistical difference (68.8% vs. 64.8%, P=0.764; 12.5% vs. 3.6%, P=0.258; 37.5% vs. 46.4%, P=0.565). 17 Mature oocytes are the minimum to have at least one euploid embryo. Oocyte vitrification does not affect embryonic, genetic and clinical results. The number of mature oocytes should be considered for fertilization in some cases.
比较新鲜卵母细胞和冷冻解冻卵母细胞的胚胎发育、倍性状态和临床结果。 这项回顾性队列研究评估了越南海防国际产科和儿科医院 HP 生育中心 79 名患者的 83 个受精周期，包括新鲜和冷冻卵母细胞。患者接受了多个卵巢刺激周期，以积累一定数量的卵母细胞进行玻璃化处理。在最后一次取卵过程中，患者的所有卵母细胞（包括冷冻和新鲜卵母细胞）都将受精。结果包括卵母细胞存活率、卵裂胚胎率、囊胚率、倍性状态、妊娠率、生化妊娠率和临床妊娠率。 解冻后的卵母细胞存活率为 96.5%。新鲜卵母细胞和冷冻卵母细胞在受精率（78.1% 对 75.5%，P=0.461）和可用卵裂胚胎率（86.9% 对 87.2%，P=0.916）方面的差异无统计学意义，但冷冻卵母细胞组的可用囊胚率较高（44.4% 对 54.0%，P=0.049）。新鲜胚胎组和玻璃化胚胎组的非整倍体胚胎、非整倍体胚胎和马赛克胚胎的百分比没有显著差异（分别为 33.8% vs. 31.6%，P=0.682；51.0% vs. 54.2%，P=0.569；15.2% vs. 12.4%，P=0.787）。妊娠率、生化妊娠率和临床妊娠率无统计学差异（68.8% vs. 64.8%，P=0.764；12.5% vs. 3.6%，P=0.258；37.5% vs. 46.4%，P=0.565）。17 成熟卵母细胞至少要有一个单倍体胚胎。 卵母细胞玻璃化不会影响胚胎、遗传和临床结果。在某些情况下，受精时应考虑成熟卵母细胞的数量。

To assess the effect of cryopreservation on stemness and proliferation potential of sheep spermatogonial stem cells (SSCs) in vitro. Sheep testicular cells were isolated and putative SSCs were enriched by the laminin-based differential plating method. Putative SSCs were co-cultured with the Sertoli cell feeder prepared by the Datura Stramonium Agglutinin (DSA-lectin)-based method. The cultured putative SSCs were cryopreserved in Dulbecco's Modified Eagle Medium-10% fetal bovine serum mixture (DMEM-10% FBS) media containing 10% dimethyl sulfoxide (DMSO) alone or 10% DMSO plus 200 mM trehalose. Cryopreserved putative SSCs were evaluated for their proliferation potential using in vitro culture and stemness by immunocytochemistry. Finally, the transfection ability of cryopreserved putative SSCs was analyzed. We isolated 91% viable testicular cells from sheep testes. The majority of the laminin enriched cells expressed the SSC related marker, ITGA6. Co-culture of sheep putative SSCs with Sertoli cell feeder resulted in the generation of stable colonies, and the expression of SSC marker was maintained after several passages. A significantly higher number of viable putative SSCs was recovered from SSCs cryopreserved in media containing 10% DMSO and 200 mM trehalose compared to 10% DMSO alone (P<0.01). Cryopreserved putative SSCs formed colonies and showed SSC marker expression similar to the non-cryopreserved putative SSCs. The appearance of green fluorescent colonies over the Sertoli cell feeder indicated that cryopreserved sheep SSCs were successfully transfected. Cryopreserved putative SSCs can retain their stemness, colony forming ability, and transfection efficiency in vitro. Our research may help in the effective preservation of germplasm and the generation of transgenic ovine species.

To measure seasonal effects on semen quality profiles, seminal biochemical and oxidative stress attributes in fresh and liquid stored semen in monsoon and dry seasons. A total of 10 Teressa bucks (3-4 years) were selected from breeding farm, ICAR-Central Island Agricultural Research Institute, Port Blair, Andaman and Nicobar Islands, India. Semen samples (n=25 per season) were collected through artificial vagina method and preserved at refrigerated temperature (5°C) for 48 h using Tris citrate glucose based extender. We detected semen quality parameters [volume, mass activity, pH, sperm concentration, total motility, viability, total sperm abnormality, and plasma membrane, acrosomal and nuclear integrities], biochemical profiles [aspartate amino transferase (AST), alanine amino transferase (ALT) and total cholesterol], and oxidative stress markers [total antioxidant capacity (TAC) and malondialdehyde (MDA)] during monsoon and dry seasons. Semen quality parameters significantly differed between seasons (P<0.05) and among storage periods (P<0.05). Volume, pH, mass activity, motility, viability, acrosomal, plasma membrane and nuclear integrities, and TAC were significantly higher (P<0.05). Sperm concentration, sperm abnormalities, MDA, AST, ALT and total cholesterol were significantly lower in fresh semen of monsoon than dry season (P<0.05). Motility, viability, acrosomal, plasma membrane and nuclear integrities, and TAC were significantly decreased (P<0.05) while sperm abnormality, AST, ALT, total cholesterol and MDA were significantly increased as liquid semen storage period advanced (P<0.05). Monsoon season has higher beneficial effects on semen quality profiles and liquid stored semen remained usable for upto 48 h. Good quality ejaculates with higher TAC and lower MDA can be cryopreserved and will be used for artificial insemination.

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 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.

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.","PeriodicalId":8564,"journal":{"name":"Asian Pacific Journal of Reproduction","volume":"12 1","pages":"170 - 181"},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47665593","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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 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.
