Abstract

PURPOSE:We compared the sexual function in women with classic forms of congenital adrenal hyperplasia (CAH) and polycystic ovary syndrome (PCOS) to find if the cause of androgen excess determines sexual functioning. METHODS:Hundred and four women (21 with CAH, 63 with PCOS and 20 healthy controls) aged 18-40 years were included into the study. All participants completed a questionnaire regarding their sociodemographic background and underwent anthropometric and basic biochemical measurements. Plasma levels of total testosterone, androstenedione, and 17-hydroxyprogesterone were measured with immunoassay. To assess the sexual functions, the Female Sexual Function Index (FSFI) questionnaire was applied. RESULTS:Apart from the higher physical activity in PCOS patients (P = 0.017), we found no significant sociodemographic differences between the studied groups. In clinical assessment, women with CAH had a lower incidence of acne (P = 0.006). Their plasma levels of 17OHP (P = 0.005) and insulin resistance index (P = 0.0248) were higher, while total testosterone (P = 0.0495) and glucose (P = 0.0061) was lower compared to the PCOS group. Significantly more women with CAH were homosexual (P = 0.003) and bisexual (P = 0.006). CAH group showed a lower total FSFI score (P = 0.0043) and lower scores in three domains: lubrication (P = 0.0131), sexual satisfaction (P = 0.0006), and dyspareunia (P < 0.0001). Higher physical activity was associated in all women with higher total FSFI score (P = 0.009) and scores in the domain of desire (P = 0.034) and sexual satisfaction (P = 0.01), while in CAH women apart from the total score (P = 0.03) and sexual satisfaction (P = 0.002) also in the domains of orgasm (P = 0.005), and pain (P = 0.03). CONCLUSIONS:CAH women present more often homosexual and bisexual orientation, while their sexual functions are impaired compared to PCOS patients.

摘要

目的: 我们比较了经典形式的先天性肾上腺皮质增生症 (CAH) 和多囊卵巢综合征 (PCOS) 女性的性功能,以发现雄激素过多的原因是否决定性功能。 方法: 研究纳入了 144 名 18 ~ 40 岁的女性 (21 名 CAH 患者,63 名 PCOS 患者和 20 名健康对照者)。所有参与者完成了关于其社会人口学背景的问卷调查,并进行了人体测量和基本生化测量。采用免疫分析法测定血浆总睾酮、雄烯二酮和 17-羟孕酮水平。应用女性性功能指数 (FSFI) 问卷评估性功能。 结果: 除了 PCOS 患者体力活动较高 (p = 0.017) 外,我们发现研究组之间没有显著的社会人口学差异。在临床评估中,CAH 女性痤疮发生率较低 (p = 0.006)。他们的血浆 17OHP 水平 (p = 0.005) 和胰岛素抵抗指数 (p = 0.0248) 较高,而总睾酮 (p = 0.0495) 与 PCOS 组相比,血糖 (p = 0.0061) 较低。明显更多的 CAH 女性为同性恋 (p = 0.003) 和双性恋 (p = 0.006)。CAH 组显示总 FSFI 评分较低 (p = 0.0043),在润滑 (p = 0.0131) 、性满意度 (p = 0.0006) 三个领域的评分较低,和性交困难 (p <0.0001)。所有女性的总 FSFI 得分 (p = 0.009) 和欲望领域得分 (p = 0.034) 与较高的体力活动相关和性满意度 (p = 0.01),而在 CAH 女性中除了总分 (p = 0.03) 和性满意度 (p = 0.002) 同样在性高潮领域 (p = 0.005),和疼痛 (p = 0.03)。 结论: 与 PCOS 患者相比,CAH 女性表现出更多的同性恋和双性恋倾向,而她们的性功能受损。

METHODS:Polycystic Ovary Syndrome (PCOS) is the most common endocrine disorder amongst women of reproductive age, whose aetiology remains unclear. To improve our understanding of the molecular mechanisms underlying the disease, we conducted a genome-wide DNA methylation profiling in granulosa lutein cells collected from 16 women suffering from PCOS, in comparison to 16 healthy controls. Samples were collected by follicular aspiration during routine egg collection for IVF treatment. Study groups were matched for age and BMI, did not suffer from other disease and were not taking confounding medication. Comparing women with polycystic versus normal ovarian morphology, after correcting for multiple comparisons, we identified 106 differentially methylated CpG sites with p-values <5.8 × 10 that were associated with 88 genes, several of which are known to relate either to PCOS or to ovarian function. Replication and validation of the experiment was done using pyrosequencing to analyse six of the identified differentially methylated sites. Pathway analysis indicated potential disruption in canonical pathways and gene networks that are, amongst other, associated with cancer, cardiogenesis, Hedgehog signalling and immune response. In conclusion, these novel findings indicate that women with PCOS display epigenetic changes in ovarian granulosa cells that may be associated with the heterogeneity of the disorder.

METHODS::Introduction: Approximately 1% of adolescents have polycystic ovary syndrome (PCOS) and almost 40-70% of these patients are overweight or obese. Obese adolescents with PCOS have more severe insulin resistance and hyperandrogenemia, a more adverse lipid profile and a worse quality of life than normal-weight adolescents with PCOS. Accordingly, weight loss is an important component of the management of these patients.Areas covered: The authors discuss the different options for weight loss in obese adolescents with PCOS. Lifestyle changes appear to be effective but adherence to this intervention is suboptimal. There are also limited data regarding the optimal diet in this population. Few small studies have evaluated the effects of pharmacotherapy in these patients. Conflicting data have been reported regarding the effects of metformin on body weight. Notably, agents that have been approved for weight loss in adults have not been evaluated in adolescents with PCOS.Expert opinion: More studies are needed to identify the most appropriate diet for obese adolescents with PCOS. Well-designed randomized controlled studies are also needed to define the safety and efficacy of pharmacotherapy in this population.

METHODS::Polycystic ovary syndrome (PCOS) is a hormonal disorder common among women of reproductive age. Although much is understood concerning the pathology of PCOS, further investigation into the influence of microribonucleic acids (miRNAs) on the proliferation of ovarian granulosa cells (GCs) is needed. This study investigated the role of specific miRNAs in ovarian dysfunction of PCOS and its effect on the proliferation of GCs. Initially, miRNA profiling was performed on the ovarian cortexes of 15 rats in which PCOS had been induced and 15 rats without PCOS (non-PCOS). This mechanical study was performed on ovarian GCs extracted from human chorionic gonadotrophin (hCG)-induced rats. Insulin was used to treat GCs to establish the PCOS cell model. Increased Equus caballus mir-9119 expression was observed and confirmed in the insulin-induced model of PCOS in GCs (GC-PCOS) as well as in the hCG-induced rats when compared to non-PCOS rats and cells. Observation and confirmation were carried out through both miRNA array and quantitative PCR. In contrast, downregulation of the nuclear factor kappa B (NFκB) p65 was observed in the PCOS cell model. Additionally, annexin V, FITC, and propidium iodide flow cytometry showed overexpression of miR-9119-induced apoptosis. In this study, we revealed that miR-9119 inhibition regulates p65 expression levels in insulin-treated GCs by binding to the 3'-untranslated of p65. Additionally, regulation of p65 expression was positively correlated with the expression of the double-stranded RNA endoribonuclease DICER. Moreover, RNA silencing/overexpression of p65 affected the functional role of miR-9119. In conclusion, GCs of PCOS, the expression of miR-9119, and targeted NFκB/p65-DICER axis are upregulated in order to maintain cell viability and prevent apoptosis, thereby promoting Anti-Müllerian hormone production in GCs. This study may provide a new understanding of the mechanism of GC dysfunction.
