Objective: The aim of this study was to compare the effects of conventional insemination (in vitro fertilization [IVF]) and intracytoplasmic sperm injection (ICSI) on the fertilization, developmental competence, implantation potential, and clinical pregnancy rate of embryos derived from in vitro matured oocytes of patients with polycystic ovary syndrome (PCOS). Methods: A prospective study was carried out among 38 PCOS patients who had undergone In vitro maturation (IVM) treatment. In total, 828 immature oocytes were collected from 42 cycles and randomly assigned for insemination by IVF (416 oocytes) or ICSI (412 oocytes). After fertilization, the embryos were cultured until the blastocyst stage and single embryos were transferred after endometrial preparation and under ultrasound guidance. Results: No significant differences were found in the maturation rate (78.1% vs. 72.6% for IVF and ICSI insemination, respectively; p= 0.076), fertilization rate (59.4% vs. 66.9% for IVF and ICSI insemination, respectively; p= 0.063), or the formation of good-quality blastocysts (40.9% vs. 46.5% for IVF and ICSI insemination, respectively; p= 0.314). Implantation and clinical pregnancy also did not show significant differences. Conclusion: There was a comparable yield of in vitro matured oocytes derived from PCOS patients in terms of fertilization, blastocyst formation, implantation rate, and clinical pregnancy between IVF and ICSI insemination. These findings provide valuable insights for choosing assisted reproductive treatment in women with PCOS, as IVM offers promising outcomes and is less invasive and less costly.

Anti-$M{\ddot{u}}llerian$ hormone (AMH), a peptide growth factor of the transforming growth $factor-{\beta}$ family, is a reliable marker of ovarian reserve. Regarding assisted reproductive technology, AMH has been efficiently used as a marker to predict ovarian response to stimulation. The clinical use of AMH has recently been extended and emphasized. The uses of AMH as a predictive marker of menopause onset, diagnostic tool for polycystic ovary syndrome, and assessment of ovarian function before and after gynecologic surgeries or gonadotoxic agents such as chemotherapy have been investigated. Serum AMH levels can also be affected by environmental and genetic factors; thus, the effects of factors that may alter AMH test results should be considered. This review summarizes the findings of recent studies focusing on the clinical application of AMH and factors that influence the AMH level and opinions on the use of the AMH level to assess the probability of conception before reproductive life planning as a "fertility test."

Background: Polycystic ovarian syndrome (PCOS) is one of the most common endocrinopathies among reproductive-age women. Its metabolic features often overlap with those associated with metabolic syndrome (MS) and insulin resistance syndrome (IRS). The objective of this study was to determine the prevalence and predictors of MS and IRS in infertile Vietnamese women with PCOS. Methods: A cross-sectional study was conducted at a tertiary fertility centre at Hue University Hospital from June 2016 to November 2017. A total of 441 infertile women diagnosed with PCOS based on the revised 2003 Rotterdam consensus criteria were enrolled. MS and IRS were defined based on the National Heart, Lung, and Blood Institute/American Heart Association Adult Treatment Panel III 2005 and American College of Endocrinology IRS 2003 criteria, respectively. Complete clinical and biochemical measurements of 318 women were available for analysis. Independent predictors of MS and IRS were identified using multivariate logistic regression. Results: The overall prevalence of MS and IRS in women with PCOS was 10.4% and 27.0%, respectively. We identified older age (>30 years) and obesity as independent predictors of MS and IRS. Elevated anti-$M{\ddot{u}}llerian$ hormone levels increased the risk of IRS, but not that of MS. Conclusion: MS and IRS are prevalent disorders among infertile Vietnamese women with PCOS. PCOS is not solely a reproductive problem. Screening and early intervention for MS and/or IRS based on anthropometric, metabolic, and reproductive hormone risk factors should be an integral part of fertility care.

Objectives: The purpose of this systematic review was to overview and evaluate the efficacy of acupuncture treatment for women with polycystic ovary syndrome (PCOS). Methods: Relevant randomized controlled studies (RCTs) were identified by database searches in MEDLINE, EMBASE, and CENTRAL, up to Dec 2013, and by additional hand searches. Data were extracted regarding anovulation, hyperandrogenism, obesity indices. Meta-analyses were separatedly conducted for the symptoms of PCOS. The risk of bias was assessed. Results: Three studies which were included for analysis, but they showed severly heterogeneity therefore meta-analysis could not be performed. Outcomes for evaluating the efficacy of acupuncture treatment for PCOS were anovulation index (menstrual frequency), hyperandrogenism index (free testosterone) and obesity index (body-mass index). For menstrual frequency, acupuncture treatment consistently suggested an interventional benefit. Although other outcomes did not suggest any enough relevant evidence to interventional benefit for acupuncture treatment. Conclusions: Acupuncture treatment appeared to improve menstrual frequency in PCOS patients. Since a limited number of RCTs were available in the current literature and those studies were also clinically heterogeneous, further research is needed to gather evidence to support acupuncture therapy in PCOS.

Polycystic ovarian syndrome (PCOS) is a very common endocrine disorder in women of reproductive age. Nerve growth factor (NGF) may be involved in the pathogenesis of PCOS. In this study, we investigated the effect of Korean red ginseng extract (KRGE) on the ovarian morphology and NGF expression in an estradiol valerate (EV)-induced rat model. Polycystic ovaries were induced by a single intramuscular injection of estadiol valerate (4 mg, dissolved in sesame oil) in adult cycling rats. KRGE was administered orally (200 mg/kg body weight/day) for 60 consecutive days, beginning 60 days after the induction. Ovarian morphology was almost normalized and NGF was normalized in the EV+KRGE group. KRGE lowered the high numbers of antral follicles and increased the number of corpora lutea in the polycystic ovaries. The results are consistent with a beneficial effect of KRGE in the treatment of PCOS.

Objectives: Polycystic ovary syndrome (PCOS) is a condition that occurs frequently among women of reproductive age and is a polygenic, multifactorial, endocrine, and metabolic disorder. PCOS is becoming more common as a result of risk factors such as current lifestyle, overnutrition, and stress. The use of traditional herbal medicine is higher among the global population. Hence, this review article focuses on the potential of Nigella sativa to manage women with PCOS. Methods: A literature search was carried out using databases including Medline, Google Scholar, EBSCO, Embase, and Science Direct, as well as reference lists, to identify relevant publications that support the use of N. sativa in the management of women with PCOS. Results: Several clinical and preclinical studies have demonstrated that the major bioactive constituent of black seed (N. sativa), thymoquinone, has potential for managing women with PCOS. Moreover, N. sativa may help to manage oligomenorrhea and amenorrhea in women with PCOS through its anti-inflammatory and antioxidant properties. Conclusion: N. sativa has potential for use as a herbal medicine for managing women with PCOS as an integrative medicine along with traditional and modern medicine in conjunction with calorie restriction and regular exercise.

Objective: Letrozole and estradiol valerate are used to treat some hormonally-responsive symptoms and also in modeling of the polycystic ovary syndrome. However, the stereological analysis of the ovary has received less attention. Estimation of the whole ovary volume using the Cavalieri method can be applied in any orientation desired, but estimation of the mean volume of the oocytes requires isotropic uniform random sectioning. Here, a combined method was developed for estimating the parameters. To our knowledge, no comparison has been made of the effects of letrozole and estradiol on the ovary. Methods: Sixty rats were divided into 4 groups receiving estradiol (4 mg/kg), olive oil, letrozole (1 mg/kg), or normal saline. After 21 days, their ovaries were studied. Results: Relative to the control group, the total volume of the ovary and the cortex increased in the letrozole-treated and estradiol-treated rats. In addition, the number of the preantral, antral, and granulosa cells decreased by 43% to 56% in the letrozole- and estradiol-treated rats. On average, a 19% increase was observed in the atretic oocytes of the letrozole-treated and estradiol-treated rats, but the mean oocyte volume decreased by 29% to 44% in letrozole- and estradiol-treated rats. Furthermore, the letrozole-treated rats showed a 5-fold and 7-fold increase in the volume of the cysts and corpus luteum, respectively. A 3-fold increase was found in the volume of both the cysts and corpus luteum in the estradiol group. Conclusion: The structural changes of the ovary were most pronounced in the letrozole-treated animals.

It was conducted the experiment, divided into three groups as normal, poor and polycystic ovary syndrome, to detect the change of protein patterns in follicular fluid on ovarian response following controlled ovarian hyperstimulation for human IVF outcome. In the normal group, it was confirmed reproducible 57 spots in the detected total 81 spots. Then 1 spot was not found in the other groups. In the poor responder group, it was found reproducible 53 spots in the detected total 98 spots. 6 spots were down-regulation and 7 spots were up-regulation comparable with normal group. There were not 5 spots in poor responder group comparable with other groups. In the polycystic ovary syndrome group, it was expressed reproducible 53 spots in the detected total 80 spots and 3 spots were just expressed in this group. However, 4 spots were not found in polycystic ovary syndrome. 9 spots were up-regulation comparable with normal group. Significant up and down-regulation spots among the each groups were identified. The results were a cytosolic carboxypeptidase, a signal-induced proliferation-associated protein 1, a ceruloplasmin, a keratin(type II cytoskeletal 1), a polypeptide N-acetylgalactosantinyltransferase 2, a serine/threonine-protein phosphatase 4 regulatory subunit 4. It was identified that 8 spots, 6 kinds of protein are corresponded with NCBInr database research, but 10 spots were failed in the identification. In conclusion, it has been confirmed change and expression of protein on the ovarian response following COH of human.
