Polycystic Ovarian Syndrome (PCOS): Exploring Its Impact on Obstetrical Outcomes

Polycystic ovarian syndrome (PCOS) disrupts ovulation leading to both infertility and miscarriage;yet, its impact on obstetrical outcomes remains largely uncertain due to conflicting findings. We analyzed data from the CDC Pregnancy Risk Assessment of Monitoring System, specifically Standard Core and Phase 8 responses, with 9549 respondents across the United States through SPSS 28 software in this cross-sectional study. Two variables assessed PCOS status in respondents: history of PCOS and PCOS during pregnancy. With a history of PCOS, there were significantly increased odds of diabetic (OR 1.665, p < 0.001), hypertensive disorders (OR 1.589, p < 0.001) during pregnancy, neonatal mortality (OR 1.550, p < 0.001), cesarean section (C/S) (OR 1.489, p < 0.001), and preterm prelabor rupture of membranes (PPROM) (OR 2.081, p < 0.001). With PCOS diagnosed during pregnancy, there were significantly greater odds of diabetes (OR 3.278, p < 0.001), hypertensive disorders (OR 2.935, p < 0.001) during pregnancy, and significantly decreased risk for small for gestational age (2 standard deviations) (OR 0.337, p = 0.024). PCOS is a significant risk factor that contributes to maternal morbidity. Our results support the hypothesis that PCOS’ impact extends well into a woman’s obstetrical journey, with varying degrees of associated adverse maternal and fetal risks. Preliminary pathophysiologic explanations associated with PCOS gestational diabetes include pre-existing insulin resistance. Meanwhile, altered placentation and endovascular changes associated with PCOS secondary to a baseline deranged metabolic environment predispose patients to developing hypertensive disorders, PPROM, and preterm delivery. Associations between neonatal mortality and C/S can be attributed to elevated maternal body mass index. The pathophysiologic link between PCOS and the above obstetrical outcomes still remains unknown, necessitating further investigation;however, this study identifies the outcomes that require the most attention at this time.

Clinical Study on the Therapeutic Effect of Combined Traditional Chinese Medicine with Acupoint Injection and Herbal Paste Application in Treating Ovulatory Dysfunction in Polycystic Ovary Syndrome (PCOS)

Objective: To observe the therapeutic effect of combined traditional Chinese medicine (TCM) therapy with acupoint injection and herbal patch application on patients with ovulatory dysfunction associated with polycystic ovary syndrome (PCOS). Methods: A total of 80 PCOS patients who received treatment at the First Affiliated Hospital of Guangxi University of Chinese Medicine between October 2022 and March 2024 were enrolled in this study. They were randomly divided into a control group (n = 40) and an observation group (n = 40). The control group received conventional Western medical treatments, while the observation group was administered TCM combined with acupoint injection and herbal patch application. Pre- and post-treatment conditions were compared between the two groups. Results: After treatment, the overall effective rate was significantly higher in the observation group compared to the control group (P 0.05). Following treatment, both ovulation and pregnancy rates increased in both groups, but the increase was more evident in the observation group, showing a statistically significant difference (P < 0.01). Conclusion: For patients with oligoovulation or anovulation due to PCOS, the combined use of TCM, acupoint injection, and herbal patch application appears to be effective in improving systemic symptoms and achieving notable clinical outcomes.

Polycystic Ovary Syndrome (PCOS) and Fertility

The polycystic ovary syndrome (PCOS) is defined as a combination of hyperandrogenism (hirsutism and acne) and anovulation (oligomenorrhea, infertility, and dysfunctional uterine bleeding), with or without the presence of polycystic ovaries on ultrasound. It represents the main endocrine disorder in the reproductive age, affecting 6% - 15% of women in menacme. It is the most common cause of infertility due to anovulation, and the main source of female infertility. When in the presence of a menstrual disorder, the diagnosis of PCOS is reached in 30% - 40% of patients with primary or secondary amenorrhoea and in 80% of patients with oligomenorrhea. PCOS should be diagnosed and treated early in adolescence due to reproductive, metabolic and oncological complications which may be associated with it. Treatment options include drugs, diet and lifestyle improvement.

Association between Metal(loid)Exposure and Risk of Polycystic Ovary Syndrome Mediated by Anti-Müllerian Hormone among Women Undergoing In Vitro Fertilization and Embryo Transfer

Objective To investigate the relationship and potential pathways between metal(loid)exposure and the risk of polycystic ovary syndrome(PCOS)in women of childbearing age.Methods This case-control study included 200 patients with PCOS(cases)and 896 non-PCOS controls with the age of 25-37 years.The concentrations of 29 metal(loid)s in the follicular fluid(FF)and clinical indicators in the serum were measured in all participants.Logistic regression analysis and mediation analysis were conducted to evaluate the associations between metal(loid)exposure and PCOS risk and investigate the possible roles of clinical indicators,respectively.Results Logistic regression analysis revealed an association between high copper levels in FF and increased PCOS risk(highest vs.lowest quartile:adjusted odds ratio=2.94,95%confidence interval:1.83-4.72).A high luteinizing hormone/follicle-stimulating hormone ratio and elevated levels of testosterone and anti-Müllerian hormone(AMH)were strongly associated with increased PCOS risk induced by high copper exposure.The mediation analysis indicated a mediating effect of AMH in the association between copper exposure and PCOS risk.Conclusion Copper may affect PCOS risk through the hypothalamic-pituitary-ovarian axis,mediated by AMH.Copper exposure and internal AMH levels are important indicators for early warning of PCOS development.

Impact of alcoholic extract from sea cucumber(Holothuria parva)on letrozole-induced polycystic ovary syndrome in adult female rats

Objective:To explore the potential therapeutic impact of an alcoholic extract derived from the sea cucumber(Holothuria parva)on letrozole-induced polycystic ovary syndrome(PCOS)in adult female Sprague-Dawley rats.Methods:Sixteen female rats,aged 8 to 10 weeks,with a mean weight of(200±20)g,were randomly assigned to four groups:the control,PCOS,and two treatment groups receiving sea cucumber extract and metformin,respectively.PCOS was induced by administering letrozole at a dose of 1 mg/kg to initiate the treatment period at 60 days of age.The study spanned four weeks,during which ovarian and uterine tissues were collected for histological examination,and blood samples were collected for hormonal levels.Results:Significant decreases in luteinizing hormone/follicle stimulating hormone(LH/FSH)and testosterone and increases progesterone levels among groups treated with sea cucumber extract were observed.While no significant differences were observed in follicle-stimulating hormone(FSH)and testosterone levels,the distinctive variations in key hormones suggested a potential role for sea cucumber alcoholic extract in ameliorating PCOS symptoms.Conclusions:This research highlights the moderate efficacy of sea cucumber extract as a therapeutic intervention for PCOS,providing a novel perspective in the search for effective remedies.The observed hormonal alterations,particularly in LH,estradiol,and progesterone,underscore the need for further exploration into the underlying mechanisms and for optimizing the application of sea cucumber extract in PCOS management.

Adult-Type Granulosa Cell Tumor with Similar Clinical Findings Seen during Ovarian Cystectomy Performed at the Same Time as Laparoscopic Ovarian Drilling for Polycystic Ovarian Syndrome: An Extremely Rare Case

Polycystic ovary syndrome (PCOS) is a major cause of anovulatory infertility. Laparoscopic ovarian drilling (LOD) is a treatment for PCOS that allows the laparoscopic identification of other intra-abdominal lesions and the provision of diagnostic treatment. This study reports a case of PCOS with an ovarian mass in which LOD was aggressively used and a granulosa cell tumor (GCT) was found. A 34-year-old woman with secondary amenorrhea and irregular menstrual cycles presented to the emergency department with abdominal pain of unknown etiology. Imaging studies revealed a 6-cm left ovarian mass with an internal appearance suggestive of a hemorrhage. The patient’s secondary amenorrhea was subsequently diagnosed as PCOS, and LOD was performed to preserve her fertility. Simultaneously, a cystectomy was performed to evaluate the tumor in the left ovary;the diagnosis was adult-type GCT. Although concomitant GCT and PCOS are extremely rare, the two conditions have similar clinical manifestations. In women of reproductive age, the impact of surgery on future fertility should be considered, and the initial surgical technique should be chosen carefully.

Enhancement of Sister Chromatid Exchanges (SCEs) in Peripheral Blood Lymphocytes of Women with Polycystic Ovary Syndrome (PCOS) <i>in Vitro</i>

The aim of the present study was to determine the level of underlying DNA damage in females with PCOS. Twenty-two women with PCOS and twenty-two healthy controls were included in this study. Patients were further categorized into three phenotypic subgroups: Subgroup A, oligo/anovulation (ANOV) and polycystic ovaries (PCO);Subgroup B, hyperandrogenism (HA) as a main characteristic (HA + ANOV or HA + PCO);Subgroup C, all three conditions present (HA + ANOV + PCO). The frequency of sister chromatid exchanges (SCEs) was used as an index of cytogenetic damage. Proliferation rate index (PRI), mitotic index (MI), average generation time (AGT) and population doubling time (PDT) were also evaluated. A significant (p < 0.01) increase in SCE levels along with a significant (p < 0.01) reduction in PRIs and MIs were observed in women with PCOS compared with healthy subjects. Additionally, subgroup C demonstrated statistically significant differences compared with others, while subgroup A had similar results with healthy females. Our results suggest that females with PCOS show increased chromosomal instability in peripheral lymphocytes and a consequent inability of the cells to promote their own mitotic cycle. A positive correlation between DNA damage and PCOS phenotypes is also reported.

Effects of Cangfudaotan Tang on Expression of Organic Anion Transporting Polypeptide (oatp2b1) in Liver and Kidney Tissues of Rats with Phlegm Dampness Type Polycystic Ovary Syndrome (PCOS)

Objective: To explore the effect of Cangfudaotan Tang on phlegm dampness type of PCOS and the role of oatp2b1 in transportation and transformation of phlegm dampness. Methods: 36 SD female rats were randomly divided into three groups: blank control group, model group and Cangfudaotan Tang group, 12 cases in each one. After PCOS rat models were made, rats of Cangfudaotan Tang group were treated with Cangfudaotan Tang (1.42 g/kg/d) by intragastric administration for 14 days;blank control and model group were given with isodose saline. The expression of oatp2b1 mRNA/Protein in liver and kidney tissues was measured and the level of testosterone (T), follicle stimulating hormone(FSH), estradiol (E2), luteinizing hormone(LH), Serum total cholesterol (TG), Triacylglycerols (TC), high density lipoprotein cholesterol (HDL-C) and low density lipoprotein cholesterol (LDL-C) were detected at the same time. Results: Compared with blank control group, the expression of oatp2b1 mRNA and the level of TC, TG, LDL, LH, FSH, T in model group were significantly increased (P < 0. 05), while the level of HDL was significantly decreased (P < 0. 05);compared with model group, the expression of oatp2b1 mRNA and the level of TC, TG, LDL in Cangfudaotan Tang group were significantly lowered (P < 0.05);the level of HDL was significantly higher;the oatp2b1 protein in kidney and liver tissues had different degrees of expression, while there was no statistical significance among the three groups. Conclusions: Oatp2b1 might be one of the material bases participating in transportation and transformation of phlegmy dampness. The mechanism of Cangfudaotan Tang treating phlegm dampness type of PCOS may be achieved by regulating the expression of oatp2b1.

Flexible GnRH Antagonist Protocol versus Progestin-primed Ovarian Stimulation (PPOS) Protocol in Patients with Polycystic Ovary Syndrome: Comparison of Clinical Outcomes and Ovarian Response

Polycystic ovary syndrome (PCOS) is one of the most common causes of infertility in women. Progestin-primed ovarian stimulation (PPOS) protocol, which used oral progestin to prevent premature luteinizing hormone (LH) surges in ovarian stimulation, has been proved to be effective and safe in patients with PCOS. The aim of the present study was to compare the efficacy of PPOS protocol with that of the traditional gonadotropin-releasing hormone (GnRH) antagonist protocol in patients with PCOS. A total of 157 patients undergoing in-vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) were recruited into this study. The patients were divided into two groups by the stimulation protocols: the GnRH antagonist protocol group and the PPOS protocol group. There was no significant difference in the clinical characteristics between the two groups. Dose and duration of gonadotropin were higher in the PPOS protocol group. Estradiol levels on the day of human chorionic gonadotropin (hCG) administration were significantly lower in the PPOS protocol group. Fertilization rates and the number of good quality embryos were similar between the two groups. Remarkably, we found 6 patients with moderate ovarian hyperstimulation syndrome (OHSS) in the GnRH antagonist protocol group but 0 in the PPOS protocol group. A total of 127 women completed their frozen embryo transfer (FET) cycles. There were no significant differences between the two groups in terms of clinical pregnancy rate per transfer, implantation rate, first-trimester miscarriage rate and on-going pregnancy rate per transfer. To conclude, PPOS protocol decreased the incidence of OHSS without adversely affecting clinical outcomes in patients with PCOS.

Clinical Value of Serum Anti-Mullerian Hormone and Inhibin B in Prediction of Ovarian Response in Patients with Polycystic Ovary Syndrome

The present study aimed to investigate the clinical value of serum anti-mullerian hormone（AMH） and inhibin B（INHB） in predicting the ovarian response of patients with polycystic ovary syndrome（PCOS）. A total of 120 PCOS patients were enrolled and divided into three groups in terms of the ovarian response： a low-response group（n=36）, a normal-response group（n=44）, and a high-response group（n=40）. The serum AMH and INHB levels were measured by enzyme-linked immunosorbent assay（ELISA）. The follicle stimulating hormone（FSH）, luteinizing hormone（LH）, and estradiol（E2） levels were determined by chemiluminescence microparticle immunoassay. The correlation of the serum AMH and INHB levels with other indicators was analyzed. A receiver operating characteristic（ROC） curve was established to analyze the prediction of ovarian response by AMH and INHB. The results showed that there were significant differences in age, body mass index（BMI）, FSH, total gonadotropin-releasing hormone（Gn RH）, LH, E2, and antral follicle counts（AFCs） between the groups（P〈0.05）. The serum AMH and INHB levels were increased significantly with the ovarian response of PCOS patients increasing（P〈0.05）. The serum AMH and INHB levels were negatively correlated with the age, BMI, FSH level, Gn, and E2 levels（P〈0.05）. They were positively correlated with the LH levels and AFCs（P〈0.05）. ROC curve analysis of serum AMH and INHB in prediction of a low ovarian response showed that the area under the ROC curve（AUC） value of the serum AMH level was 0.817, with a cut-off value of 1.29 ng/m L. The sensitivity and specificity were 71.2% and 79.6%, respectively. The AUC value of serum INHB was 0.674, with a cut-off value of 38.65 ng/m L, and the sensitivity and specificity were 50.7% and 74.5%, respectively. ROC curve analysis showed when the serum AMH and INHB levels were used to predict a high ovarian response, the AUC value of the serum AMH level was 0.742, with a cut-off value of 2.84 ng/m L, and the sensitivity and specificity were 72.7% and 65.9%, respectively; the AUC value of the serum INHB level was 0.551 with a cut-off of 45.76 ng/m L, and the sensitivity and specificity were 76.3% and 40.2%, respectively. It was suggested the serum AMH and INHB levels have high clinical value in predicting the ovarian response of PCOS patients.

Synchrony between Ovarian Function &Sleep in Polycystic Ovary Syndrome Patients

Polycystic ovary syndrome (PCOS) is a complex, multifaceted, heterogeneous disorder, affecting 4% to 18% of reproductive-aged women and is associated with reproductive, metabolic and psychological dysfunction. In this study we determined the relationship between the time to sleep and serum levels of neurohormones in polycystic ovary syndrome (PCOS). Totally 77 PCO patients(case group) and 97 non-PCOS infertile women (control subjects) participated in this study between February 2012 and February 2013. A PSQI sleep questionnaire was completed by each patient in both groups. PSQI sleep questionnaire score and serum concentration of adrenaline, noradrenaline, melatonin, β-endorphin, cortisol and progesterone were compared in two groups. The results of the study indicate that serum levels of melatonin and β-endorphin were lower in women with PCOS. Serum level of stress hormones, adrenaline and noradrenaline were significantly correlated with patients’ sleep time in study group. Serum level of adrenaline in control group was significantly lower in women who wake up earlier in the morning. All hormones except for cortisol had no significant correlation with PSQI global score in both groups and also the people who sleep less than 8 hours had lower cortisol level. These data showed that changes in cortisol in PCO women were due to damage of disturbed sleep at night. Our preliminary work provided this study with new insight into the interactions between sleep-wake cycles in PCO women with specific sleep patterns.

Influence of Thioctic Acid on the Hyperinsulinemia and Ovarian Volume in Female Patients with Polycystic Ovary Syndrome

45 female patients with polycystic ovary syndrome took thioctic acid (Thioctacid-HR), 600 mg (n = 25) or high protein diet (n = 20). Fast insulin and glucose stimulus insulin were investigated before and after 3 months taken treatment. The use of thioctic acid, 600 mg is a new effective pathogenetics therapy of polycystic ovary syndrome on influence of hyperinsulinemia, HOMA-IR index and ovary volume in female patients with polycystic ovary syndrome.

Observation on human ovarian theca cell and granulosa cell interaction in polycystic ovary syndrome

Objective: To investigate the role of human theca cell(TC) and granulo sa cell(GC) interaction and insulin(INS) in steroidogenesis in normal ovarian cy cle and in patients with PCOS. Methods: Ovarian theca and granulosa cells from eleven normal wo men and eight PCOS patients were co-cultured on opposite side of collagen with or without INS. The concentrations of estradiol(E2), progesterone(P) and andro stenedione (A) in the culture medium were examined by ELISA method.Results: When co-cultured with GC, TC in PCOS group produced mo re A and less P than those of normal group. When co-cultured with theca cells, granulosa cells in PCOS group produced more E2 than those of normal group. Add ition of INS increased the difference significantly.Conclusions: The GC and TC interaction from the normal and PCOS ovaries is different. There is a high A and high E2 intraovary loop of PC OS leading to premature arrest of follicle growth and anovulation. Insulin may p lay an important regulatory role.

Effect of Astragalus-hawthorn on ovarian reproductive function and inflammatory mechanism of action in rats with polycystic ovary syndrome

Objective:To investigate the effects of prophylactic administration of Astragalus-Hawthorn on ovarian reproductive function and inflammatory mechanism in rats with polycystic ovary syndrome(PCOS).Methods:Fifty 21-day-old female rats were randomly divided into five groups of 10 rats each:Normal group,Model group,Astragalus group,Hawthorn group and Astragalus-Hawthorn group.All groups,except the normal group,were fed a high-fat model diet.Each treatment group received astragalus,hawthorn and an astragalus-hawthorn solution orally during the molding period for an intervention period of 15 weeks.The estrous cycle of the rats in each group was observed under the microscope from week 8,the interference rate was calculated,changes in ovarian tissues were observed by HE staining and the levels of sex hormones,proinflammatory and anti-inflammatory factors in the serum of the rats were measured by ELISA.Results:Rate of estrous cycle disorders were more frequent in the model group than in the normal group.(P<0.01);ovarian tissue was polycystic,with few corpora lutea and sinusoids and numerous follicular ovarian cysts;Luteinising hormone/follicle-stimulating hormone(LH/FSH),testosterone(T),interleukin 6(IL-6),interleukin 17A(IL-17A)and tumour necrosis factor(TNF-α)levels were significantly higher in the model group than in the normal group;interleukin 10(IL-10)was significantly lower than in the normal group(P<0.05).Compared to the model group,rats in the Astragalus and hawthorn groups had a lower rate of estrous cycle disorders(P<0.01);the number of cystic follicles in the ovarian tissue decreased;the number of mature follicles and corpus luteum increased;LH/FSH,T,IL-6 and IL-17A levels were significantly lower in the Astragalus group,hawthorn group and the Astragalus and hawthorn groups;TNF-αlevels were significantly lower in the astragalus and hawthorn groups;IL-10 levels were significantly higher in the hawthorn and astragalus hawthorn groups(P<0.05).IL-10 levels were significantly higher in the astragalus and hawthorn groups(P<0.05).Compared to the astragalus group,T levels were significantly lower in the astragalus and hawthorn groups and IL-10 levels were significantly higher in the astragalus and hawthorn groups(P<0.05).Compared to the hawthorn group,levels of T and IL-17A were significantly lower in the astragalus-hawthorn group(P<0.05).Conclusion:Astragalus-Hawthorn prophylactic administration can improve ovarian reproductive function in rats with PCOS,and the mechanism of action may be related to reducing the levels of pro-inflammatory factors IL-6,IL-17A and TNF-α,increasing the levels of anti-inflammatory factor IL-10,and reducing the inflammatory state.

Effect of Mitochondrial Function of Ovarian Granulosa Cells on In Vitro Fertilization and Embryo Transfer Outcomes in Obese Polycystic Ovary Syndrome Patients

Objective:To investigate the effect of abnormal ovarian granulosa cell metabolism on in vitro fertilization and embryo transfer(IVF-ET)outcomes in obese polycystic ovary syndrome(PCOS)patients.Methods:Patients with PCOS who met the study criteria were screened according to the inclusion criteria.A total of 32 patients with obese PCOS were recruited into the study group,and 39 patients with non-obese PCOS were recruited into the control group.The general data(age,body mass index,and years of infertility),insulin resistance index(HOMA-IR),follicle-stimulating hormone(FSH),luteinizing hormone(LH),granulosa cell mitochondrial function,and IVF-ET outcome of patients in the study group and control group were retrospectively analyzed.Results:The differences in age and years of infertility between the study group and the control group were insignificant(P>0.05),and the body mass index(BMI)of the study group and control group was 30.5±1.24 kg/m2 and 22.3±1.12 kg/m2,respectively,in which the difference was statistically significant(P<0.05);the HOMA-IR of the study group was significantly higher than that of the control group(P<0.05);the reactive oxygen species(ROS)in the study group was significantly higher than that in the control group(P<0.05),and the ATP content in the study group was significantly lower than that in the control group(P<0.05);comparing the FSH and LH levels between the two groups,the difference was not statistically significant(P>0.05);the rate of IVF-ET failure was significantly higher in the study group than in the control group.Conclusion:PCOS is a complex endocrine disorder,and obesity is one of the independent risk factors for the development of PCOS.

Review of nonalcoholic fatty liver disease in women with polycystic ovary syndrome

Polycystic ovary syndrome(PCOS) is the most common endocrine disorder in reproductive-aged women. Women with PCOS frequently have metabolic complications including insulin resistance(IR), early diabetes, hypertension and dyslipidemia. Recent studies have demonstrated an association between PCOS and another metabolic complication: nonalcoholic fatty liver disease(NAFLD). NAFLD occurs as a result of abnormal lipid handling by the liver, which sensitizes the liver to injury and inflammation. It can progress to nonalcoholic steatohepatitis(NASH), which is characterized by hepatocyte injury and apoptosis. With time and further inflammation, NASH can progress to cirrhosis. Thus, given the young age at which NAFLD may occur in PCOS, these women may be at significant risk for progressive hepatic injury over the course of their lives. Many potential links between PCOS and NAFLD have been proposed, most notably IR and hyperandrogenemia. Further studies are needed to clarify the association between PCOS and NAFLD. In the interim, clinicians should be aware of this connection and consider screening for NAFLD in PCOS patients who have other metabolic risk factors. The optimal method of screening is unknown. However, measuring alanine aminotransferase and/or obtaining ultrasound on high-risk patients can be considered. First line treatment consists of lifestyle interventions and weight loss, with possible pharmacologic interventions in some cases.

Correlation between IL-1β,IL-1Ra gene polymorphism and occurrence of polycystic ovary syndrome infertility

Objective:To explore the relationship between IL-1β.IL-1Ra gene polymorphism and the occurrence of polycystic ovary syndrome(PCOS) infertility.Methods:A total of 59 PCOS infertility cases visiling the reproductive center of our hospital from Mar.2010 to Mar.2012 and 56 healthy women were selected.ELISA method was used lor the detection of IL-1β.IL-1Ra lewis,and the levels of serum supersensitivity C reaction protein(US-CRP).insulin(FINS),follieule-stimulating hormone(FSH) and fasting blood—glucose(FRG) were detected.PCR analysis technology was adopted to detect the gene polymorphism of the.511 site of IL-1βand the second introne of IL- 1Ra.Results:The levels of IL-1β.IL-1Ra.US-CRP.FINS and FBG in blood scrum of patients in PCOS group were significantly higher than those in control group(P【0.05 or P【0.01).The level of FSH in PCOS group was significantly lower than that in control group(P【0.05).The genotypic frequency of T/T.the 511 site of IL-1βin PCOS group was 42.37%.significantly higher than 1250%in control group 【P【0.01).The frequency of T allele was also significantly higher than that in control group(P【0.01).The genotypic frequency ofⅠ/Ⅴ.the second introne of IL-1Ra in PCOS group was 20.34%,signicianlly higher than 3.57%in control group(P【0.05).The frequency of V allele in PCOS group was significantly higher than that in control group(P【0.05).Conclusions: T allele of the 511 site of IL-1βgene and V allele of the second inlrone of IL-1Ra gene might be the genetic basis of the rising of IL-1β.IL-1Ra and US-CRP levels in blood serum of PCOS patients,and are associated with the infertility occurrence of PCOS patients.

Expression of Leptin Long-form Receptor mRNA in Luteinized Granulosa Cells of Obese Women with Polycystic Ovary Syndrome

To investigate the expression of mRNA of leptin long-form receptor （OB-Rb） in luteinized granulosa ceils of obese women with polycystic ovary syndrome （PCOS）, and to determine the role of leptin in the physiopathology of PCOS, luteinized granulosa cells were collected from the follicle fluid of 10 obese women who met the diagnostic criteria for PCOS and their BMI was equal to or greater than 25 kg/m^2, and at the same time, granulosa cells were collected from 10 normal women undergoing IVF-ET who served as the control group. Some luteinized granulosa cells were taken from normal women for in-vitro culture, into which human leptin of different concentrations was added （0, 10, 100 and 1000 ng/mL）. After stimulation with leptin for 48 h, RT-PCR was employed for the detection of the expression of OB-RLInRNA in the luteinized granulosa cells. Our results showed that the level of OB-RLmRNA in luteinized granulosa cells of obese PCOS women was higher than those in the control （P〈0.05）. In luteinized granulosa cells cultured in vitro and stimulated by human leptin for 48 h, the level of OB-RLmRNA was higher than those without leptin stimulation （P〈0.01）, and when leptin concentration was at 100 ng/mL, and the level of OB-RLmRNA reached a peak, It is concluded that in obese PCOS women, the level of serum leptin is increased, which promotes the expression of OB-RL in luteinized granulosa cells and increases the sensitivity of the granulosa cells to leptin. Leptin may contribute to anovulation in obese women with PCOS.

Polycystic ovary syndrome patients with high BMI tend to have functional disorders of androgen excess:a prospective study

Biochemical or clinical changes of hyperandrogenism are important elements of polycystic ovary syndrome （PCOS）. There is currently no consensus on the definition and diagnostic criteria of hyperandrogenism in PCOS. The aim of this study was to investigate the complex symptoms of hyperandrogenic disorders and the correlations between metabolism and hyperandrogenism in patients with PCOS from an outpatient reproductive medicine clinic in China. We conducted a case control study of 125 PCOS patients and 130 controls to evaluate differences in body mass index （BMI）, total testosterone （TT）, modified Ferriman-Gallwey hirsutism score, sex hormone binding globulin （SHBG）, homeostasis model assessment-estimated insulin resistance （HOMA-IR） and free androgen index （FAI） between PCOS patients and controls and subgroups of PCOS. The prevalence of acne and hirsutism did not differ significantly between the hyperandrogenic and non-hyperandrogenic subgroup. Patients with signs of hyper- androgenism had significantly higher BMI （P 〈 0.05）, but differences in TT, SHBG, FAI and waist/hip ratio were insignificant. The odds ratio of overweight was calculated for all PCOS patients. Our results suggest that PCOS patients with high BMI tend to have functional disorders of androgen excess; therefore, BMI may be a strong pre-dictor of hyperandrogenism in PCOS.
