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.

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.

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.

Probiotics supplementation for management of type Ⅱ diabetes risk factors in adults with polycystic ovarian syndrome: a meta-analysis of randomized clinical trial

This meta-analysis of randomized controlled trials aimed to evaluate the effects of probiotic supplementation on glucose homeostasis in patients with polycystic ovary syndrome(PCOS).The meta-analysis was performed in accordance with the Cochrane Handbook guidelines and relevant the preferred reporting items for systematic reviews and meta-analyses(PRISMA)statement criteria.Of 825 identified reports,11 randomized clinical trials were included in the meta-analysis.An analysis of pooled extracted data revealed that supplementation with probiotics significantly decreased fasting blood glucose(FBG,n=7;standardized mean difference(SMD)=−0.40;95%confidence interval(CI):−2.02,−0.02;P=0.04)and insulin levels(n=6;SMD=−0.57;95%CI:−0.89,−0.25;P=0.0004)and the homeostatic model assessment of insulin resistance(n=7;SMD=−0.64;95%CI:−0.96,−0.31;P=0.0001)while increasing the quantitative insulin sensitivity check index(QUICKI,n=5;SMD=0.58;95%CI:0.08,1.09;P=0.02)in patients with PCOS.The FBG-reducing effect decreased as the baseline body mass index(BMI)and mean age of the participants increased.Indeed,a greater number of bacterial species and a higher bacterial dose were shown to reduce QUICKI effectively.The systematic review indicated that probiotic supplementation may help to control glucose homeostasis in adults with polycystic ovarian syndrome.

Effect of vitamin supplementation on polycystic ovary syndrome and key pathways implicated in its development:A Mendelian randomization study

BACKGROUND Many epidemiologic investigations have explored the relationship between viatmins and polycystic ovary syndrome(PCOS).However,the effectiveness of vitamin,vitamin-like nutrient,or mineral supplementation in reducing the risk of PCOS remains a subject of debate.AIM To investigate the impact of plasma levels of vitamins A,B12,D,E,and K on PCOS and key pathways implicated in its development,namely,insulin resistance,hyperlipidemia,and obesity,through Mendelian randomization(MR)analysis.METHODS Single nucleotide polymorphisms associated with vitamin levels were selected from genome-wide association studies.The primary analysis was performed using the random-effects inverse-variance-weighted approach.Complementary analyses were conducted using the weighted median,MR-Egger,MR-robust adjusted profile score,and MR-PRESSO approaches.RESULTS The results provided suggestive evidence of a decreased risk of PCOS with genetically predicted higher levels of vitamin E(odds ratio[OR]=0.118;95%confidence interval[CI]:0.071–0.226;P<0.001)and vitamin B12(OR=0.753,95%CI:0.568–0.998,P=0.048).An association was observed between vitamin E levels and insulin resistance(OR=0.977,95%CI:0.976–0.978,P<0.001).Additionally,genetically predicted higher concentrations of vitamins E,D,and A were suggested to be associated with a decreased risk of hyperlipidemia.Increased vitamins K and B12 levels were linked to a lower obesity risk(OR=0.917,95%CI:0.848–0.992,P=0.031).CONCLUSION The findings of this MR study suggest a causal relationship between increased vitamins A,D,E,K,and B12 levels and a reduced risk of PCOS or primary pathways implicated in its development.

Effect of laparoscopic sleeve gastrectomy on related variables of obesity complicated with polycystic ovary syndrome

BACKGROUND Polycystic ovary syndrome(PCOS)is closely related to obesity,and weight loss can significantly improve the metabolic,endocrine and reproductive functions of obese individuals with PCOS.However,the efficacy of laparoscopic sleeve gastrectomy(LSG)for obesity with PCOS are unclear.AIM The purpose of the study was to investigate the effect of LSG on related variables in obese patients with PCOS.METHODS A retrospective analysis was performed on 32 obese patients with PCOS who received LSG treatment at the Third Hospital of Shanxi Medical University from 2013 to 2020.The changes in anthropometric indices,insulin,testosterone,estradiol,follicle stimulating hormone(FSH),luteinizing hormone(LH),menstrual cycle and LH/FSH ratio before and 1 mo,3 mo,6 mo and 12 mo after the operation were statistically analyzed.RESULTS At 1 mo,3 mo,6 mo and 12 mo after surgery,the anthropometric indices,such as body weight and body mass index,of all patients were lower than those before the operation.The percentage excess weight loss(EWL%)at 1 mo,3 mo,6 mo and 1 year of follow-up were 25,40,46 and 65,respectively.The PCOS-related indices,such as insulin,testosterone,estradiol,follicle stimulating hormone(FSH),luteinizing hormone(LH)and menstrual cycle,were improved to varying degrees.During the 1-year follow-up,the average serum testosterone decreased from preoperative 0.72 ng/mL to 0.43 ng/mL(P<0.05),average fasting insulin level(9.0 mIU/mL,preoperative 34.2 mil,LH level,4.4 mIU/mL,preoperative 6.1 mIU/mL).The level of FSH(3.8 U/L,4.8 U/p0.05)and the ratio of LH/FSH(0.7,1.3/p0.05)were more relieved than those before surgery.During the postoperative follow-up,it was found that the menstrual cycle of 27 patients(nasty 27)returned to normal,and 6 patients(18%)who intended to become pregnant became pregnant within 1 year after surgery.CONCLUSION The weight loss effect of LSG is obvious and affirmative,and the endocrine index of obese patients with PCOS is also improved to some extent,although the mechanism is not clear.Laparoscopic sleeve gastrectomy is expected to become a backup choice for patients with polycystic ovaries in the future.

Effects of Qigongwan on Wnt/β-catenin Signaling Pathway in Rats with Polycystic Ovary syndrome

[Objectives] To explore the therapeutic effect and mechanism of Qigongwan on PCOS model rats by detecting the changes in sex hormone levels in rats with polycystic ovary syndrome (PCOS), and observing the effects of ovarian pathological morphological changes, apoptosis and expression of Wnt/β-β catenin signaling pathway protein. [Methods] Ten of 40 female SD rats were randomly selected as the normal group, and the other 30 rats were treated with letrozole combined with high-fat diet to establish the PCOS rat model. After successful modeling, the model group was randomly divided into Qigongwan group, positive Daying-35 (Ethinylestradiol and Cyproterone Acetate Tablets) group and model group, with 10 rats in each group. Qigongwan group was given 14.7 g/(kg·d) by gavage, Daying-35 group was given 0.21 mg/(kg·d) by oral gavage, and normal group and model group were given the same amount of distilled water, and the intervention lasted for 21 d. ELISA method was used to detect the levels of hormones such as follicle-stimulating hormone (FSH), luteinizing hormone (LH), testosterone (T), estradiol (E 2) and progesterone (P) in serum. HE staining was used to observe the pathological morphological changes of ovarian tissues;TUNEL staining was used to observe apoptosis of ovarian tissue granule cells;the expression of Wnt, β-catenin protein in rat ovarian tissue was detected by immunohistochemistry. [Results] (i) Compared with the model group, Qigongwan group and Daying-35 group could significantly increase serum E 2 and P levels, significantly reduce serum T levels ( P <0.01), significantly reduce serum LH levels and LH/FSH ratio ( P <0.01), and increase serum FSH levels ( P <0.05) in different degrees. (ii)The results of HE staining showed that compared with the model group, Qigongwan and Daying-35 groups could improve follicular development and reduce atretic follicles in different degrees. Compared with Daying-35 group, the number of GC layers in Qigongwan group was significantly increased. (iii) The results of TUNEL staining showed that compared with the model group, the rate of TUNEL-positive cells in the Qigongwan group and Daying-35 group decreased significantly ( P <0.01). (iv) The immunohistochemical results showed that compared with the model group, the expression levels of wnt and β-catenin in the Qigongwan group and the Daying-35 group increased in different degrees ( P <0.05), and the expression range increased. [Conclusions] Qigongwan can regulate the secretion level of sex hormones such as FSH and LH, improve the pathological damage of ovarian tissue, and inhibit apoptosis of ovarian granule cells, and its mechanism may be related to the activation of Wnt/β-catenin signaling pathway.

Research Progress on Mechanism of Ovulation Disorder in Polycystic Ovary Syndrome

Polycystic ovary syndrome(PCOS)is a reproductive endocrine disease characterized by ovulation disorder,hyperandrogenism and/or polycystic ovary.Follicular development disorder caused by PCOS accounts for up to 75%of anovulatory infertility,which is a common cause of infertility and affects up to 15%of reproductive aged women worldwide.Oxidative stress,chronic inflammation,endoplasmic reticulum stress and other pathological conditions coexist in the ovarian microenvironment of PCOS,which are further aggravated under the action of high levels of androgens,synergistically deteriorating the follicular microenvironment,leading to ovulation disorders in PCOS patients.This paper briefly reviewed the research on the mechanism of PCOS ovulation disorder in recent years.

Polycystic Ovary Syndrome-Related Infertility Based on the Theory of“Liver and Kidney Homology”

Polycystic ovary syndrome(PCOS)is an endocrine disorder caused by hypothalamic-pituitary-ovarian(HPO)axis dysfunction.In the field of gynecology and reproduction,PCOS has emerged as both a research hot spot and a challenging area of study.According to Chinese medicine,this disease is related to kidney deficiency,phlegm and dampness obstruction,blood stasis and interconnection,Chong pulse impassability,the lack of Ren pulse,and the loss of uterine nourishment,all of which affect the normal development and maturation of eggs as well as the duration at which menstrual blood stores.In this paper,based on the theoretical basis of“liver collects blood,regulates the flow of qi,and is the master of drainage,”we explore the rationality of the treatment of this disease from the perspective of“liver and kidney have the same origin”and the development of PCOS-related infertility in relation to dysfunctional internal organs.We also explore the feasibility of treatment from the perspective of“liver and kidney homology,”expand the ideas for treatment,as well as develop and innovate the application of organ identification in PCOS in relation to infertility.

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.

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.

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.

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.
