Hyperandrogenic Polycystic Ovary Syndrome Women Research Articles

Curcumin and Teupolioside attenuate signs and symptoms severity associated to hirsutism in PCOS women: a preliminary pilot study.

Hirsutism affects 5-15% of women of reproductive age, with approximately 80% of these women having polycystic ovary syndrome (PCOS). The etiopathogenesis of PCOS remains unclear, the clinical characteristics of PCOS include hyperandrogenism, generally manifested as hirsutism and acne, and both these clinical symptoms are treated with oral contraceptive pills (OCPs), topical medications or antiandrogens. Curcumin (diferuloylmethane) and Plant sterols, such as a phenylpropanoid glycosides of Ajuga reptans, known as Teupolioside, have attracted considerable attention due to their pharmacological properties. Taking into consideration wide-ranging pharmacological and biological properties and the safety of herbal extracts, we proposed a combination of curcumin and teupolioside to evaluate the anti-androgenic properties in women with PCOS and clinical signs of hyperandrogenism. Six hyperandrogenic PCOS women with a hirsutism score (HS) > 20, according to Ferriman-Gallwey scoring system, were involved in the study. These women were treated with a galenical preparation mixture containing curcumin and teupolioside and clinical features were assessed after 12 weeks. The nutraceutical combination containing curcumin/teopolioside ameliorated clinical manifestations associated to hyperandrogenism in women with PCOS after a 12-weeks treatment. This pilot study suggests that a curcumin/teopolioside nutraceutical combination is beneficial for improving various clinical manifestations associated to abnormal hormonal parameters in PCOS women, as well as signs and symptoms associated to hyperandrogenism.

Association of severity of menstrual dysfunction with hyperinsulinemia and dysglycemia in polycystic ovary syndrome.

Is the severity of menstrual cyclicity related to hyperinsulinemia and dysglycemia in women with hyperandrogenic polycystic ovary syndrome (PCOS)? Hyperandrogenic PCOS women with amenorrhea, compared to those with oligomenorrhea or eumenorrhea, had a greater risk of post-challenge hyperinsulinemia, which may explain their higher prevalence of dysglycemia. PCOS is associated with metabolic dysregulation including insulin resistance (IR) and hyperinsulinemia, risk factors for type 2 diabetes mellitus (T2DM) and other vascular-metabolic morbidities. Although the severity of menstrual cyclicity is associated with IR in PCOS, it is unclear whether, and to what extent, it is related to hyperinsulinemia and glycemic abnormalities. We prospectively compared the degree of menstrual cyclicity with the presence of dysglycemia (elevated 1-h plasma glucose ≥155 mg/dl; abnormal glucose tolerance [AGT], including prediabetes and T2DM; and AUC for glucose [G-AUC]) or dynamic state hyperinsulinemia (peak insulin levels either at 1 or 2 h of the oral glucose tolerance test (oGTT) and AUC for insulin [I-AUC]) in 333 hyperandrogenic PCOS women. In a tertiary care setting, hyperandrogenic PCOS participants with ovulatory eumenorrhea (Ov-Eumeno, n = 25), anovulatory eumenorrhea (Anov-Eumeno, n = 33), oligomenorrhea (Oligo, n = 150) and amenorrhea (Ameno, n = 125) underwent comprehensive phenotyping and a 2-h 75 g oGTT. Mean BMI was greater among Ameno women than among Oligo, Anov-Eumeno or Ov-Eumeno women. Adjusting for BMI, the Ameno group demonstrated higher mean 1- and 2-h insulin and glucose, peak insulin and I-AUC and G-AUC, and either had a higher, or tended toward having a higher, prevalence of elevated 1-h glucose level and prevalence of AGT than the Oligo, Anov-Eumeno or Ov-Eumeno groups. In logistic regression, adjusting for BMI, Ameno women were more likely to have: AGT than Oligo women (odds ratio [OR]: 2.3; 95% CI: 1.3 to 4.2); elevated 1-h glucose (OR: 10.2; CI: 1.3-79.7) than those with Ov-Eumeno; and both AGT (OR: 1.7; CI: 1.1-2.6) and elevated 1-h glucose (OR: 1.8; CI: 1.1-2.8) than those with Anov-Eumeno or Ov-Eumeno when combined. Race/ethnicity, age, waist-to-hip ratio, fasting insulin and glucose, and biochemical or clinical measures of hyperandrogenism were similar across the four menstrual categories. Our study was limited by its cross-sectional nature and by studying women affected by PCOS as defined by the Androgen Excess & PCOS Society criteria (i.e. Rotterdam Phenotypes A, B and C) who were identified in the clinical setting. Consequently, extrapolation of the present data to other PCOS phenotypes (e.g. PCOS Phenotype D) should be made with caution. In hyperandrogenic PCOS phenotypes, a history of amenorrhea, compared to oligomenorrhea or eumenorrhea, suggests a more severe cardiometabolic risk, including a higher degree of hyperinsulinemia and greater prevalence of glycemic abnormalities. These findings may assist in refining the treatment and screening guidelines for glycemic abnormalities in PCOS.

O-161 Cumulative live birth rate after a freeze-all approach in women with polycystic ovaries: does the PCOS phenotype have an impact?

Abstract Study question Do cumulative live birth rates (CLBR) differ between PCOS phenotypes when a freeze-all strategy is used to prevent OHSS after ovarian stimulation (OS)? Summary answer When conventional-dose OS resulted in high response, a CLBR of ∼ 70% was observed after “freeze-all” in women with PCOS, irrespective of their phenotype. What is known already Previous observational studies have shown that CLBR in women with PCOS who undergo assisted reproductive technologies (ART) may depend on their phenotype. When OS was performed with caution to avoid ovarian hyperresponse, CLBR was lower in women with a hyperandrogenic PCOS phenotype. However, when women with PCOS do exhibit hyperresponse and a freeze-all strategy is used, the impact of the PCOS phenotype on the clinical outcome of the ART cycle is unclear. Study design, size, duration This is a single-centre, retrospective cohort study including 422 women with polycystic ovary syndrome (PCOS) as defined by Rotterdam criteria or PCO-like ovarian morphology-only (PCOM) in whom a freeze-all strategy was applied after GnRH agonist triggering in the context of hyperresponse defined as ³19 follicles of ³11mm in their first or second IVF-ICSI cycle between January 2015 and December 2019 in a tertiary referral hospital. Participants/materials, setting, methods PCOS phenotype was based on hyperandrogenism (H), ovulatory dysfunction (O) and PCO-like ovarian morphology (P). Ovarian stimulation was performed with rFSH or HPhMG, adjusted to BMI. The primary outcome was cumulative live birth rate (CLBR) resulting from the transfer of all cryopreserved embryos from the same IVF-ICSI cycle. Patient and cycle characteristics and laboratory and clinical data were analysed. Data were analysed by multivariate logistic regression adjusting for covariates. Main results and the role of chance In total, 91/422 (21.6%) patients had PCOS phenotype A (HOP); 33 (7.8%) had phenotype C (HP), 161/422 (38.2%) had phenotype D (OP) and 137/422 (32.5%) had PCOM (n = 137). BMI, AMH and AFC were significantly different between phenotype groups (p < 0.001), and highest in PCOS phenotype A. The type of gonadotropin used, as well as the mean daily and total stimulation dose were comparable for all groups. The mean number of retrieved oocytes was comparable among groups (22.4±10.8 for phenotype A, 21.4±7.1 for phenotype C, 20.4±7.8 for phenotype D and 22.2±9.7 for PCOM; p = 0.46). The mean number of embryos available for vitrification differed significantly (4.4±3.7, 5.7±3.4, 5.7±3.4 and 5.2±3.6, respectively; p = 0.005). Following the first frozen embryo transfer, LBR was comparable among groups (41.5%, 43.3%, 49.3% and 38.5%, respectively; p = 0.31). Unadjusted CLBR was also similar (69.2%, 69.7%, 79.5% and 67.9%, respectively; p = 0.11). The multivariate logistic regression model adjusting for age, BMI, number of oocytes and embryo stage (cleavage vs. blastocyst stage) confirmed that the PCOS/PCOM phenotype did not have any impact on CLBR (OR 0.80, CI 0.28-2.29 (phenotype C); OR 1.40, CI 0.67-2.90 (phenotype D); OR 0.65, CI 0.31-1.34 (PCOM); p = 0.1, with phenotype A as reference). Limitations, reasons for caution These data should be interpreted with caution as the retrospective nature of the study holds the possibility of unmeasured confounding factors. The results cannot be generalised to all ART cycles in women with polycystic ovaries as they pertain to those cycles where OS leads to hyperresponse. Wider implications of the findings In subfertile women with PCOS eligible for ART, hyperresponse after OS confers excellent cumulative live birth rates when a freeze-all strategy is used, eliminating unfavourable clinical outcomes that had previously been observed in hyperandrogenic PCOS women after mild OS targeting normal ovarian response and fresh embryo transfer.

Steroid metabolome profiling of follicular fluid in normo- and hyperandrogenic women with polycystic ovary syndrome

Polycystic ovary syndrome (PCOS) is a heterogeneous disease defined by the presence of at least two of the following features: hyperandrogenism, oligoanovulation (OA), and polycystic ovarian morphology (PCOM). Hyperandrogenism is considered the cornerstone of PCOS. However, the most prevalent phenotype in Chinese women with PCOS is OA + PCOM [normo-androgenic PCOS (NA-PCOS)]. It has been reported that PCOS women have higher androgen levels in follicular fluid (FF), but whether NA-PCOS women have the same intrafollicular steroid profiles as hyperandrogenic PCOS (HA-PCOS) women has not been explored.In this study, we analyzed 17 steroids in stimulated size-matched ovarian follicles (16−18 mm) from 166 controls and 141 PCOS women [87 NA-PCOS and 54 HA-PCOS women, defined by a single serum testosterone (T) immunoassay measurement] using liquid chromatography tandem mass spectrometry, and investigated their relationship with baseline characteristics. No significant differences in intrafollicular steroid levels and product/precursor ratios between NA-PCOS and HA-PCOS women were observed, though HA-PCOS women had significantly higher serum luteinizing hormone and T levels than NA-PCOS women. NA-PCOS and HA-PCOS women had significantly higher levels of androstenedione (AD), T and free androgen index, higher enzyme activity of P450c17 (AD/17OH-progesterone), 3βHSD2 (17OH-progesterone /17OH-pregnenolone) and P450c11 (corticosterone /11-deoxycorticosterone), lower levels of pregnenolone, 17OH-pregnenolone and 11-deoxycorticosterone, and decreased enzyme activity of P450aro (estrone/AD and estradiol/T) and 5α-reductase (dihydrotestosterone/T) in FF than controls. NA-PCOS women had significantly higher intrafollicular cortisol levels and lower 11βHSD2 (cortisone/cortisol) activity than controls. Baseline serum T levels were slightly correlated with intrafollicular estrogens (E1: r = 0.192, p = 0.019; E2: r = 0.248, p = 0.002; E3: r = 0.248, p = 0.002) and androgens (DHEAS: r = 0.276, p = 0.001; AD: r = 0.185, p = 0.032; T: r = 0.173, p = 0.044) in controls and PCOS women respectively. Serum anti-Müllerian hormone (AMH) levels and antral follicle count (AFC) were correlated with intrafollicular cortisol (AMH: r = 0.380, p = 0.000; AFC: r = 0.177, p = 0.036) and corticosterone (AMH: r = 0.212, p = 0.048; AFC: r = 0.219, p = 0.009) levels in PCOS women.In conclusion, NA-PCOS and HA-PCOS women had statistically similar steroid metabolome profiles in FF, both of which showed a generally decreased steroidogenesis and hyperandrogenism compared to controls.

The efficacy of gonadotropin-releasing hormone (GNRH) agonist before frozen embryo transfer in improving pregnancy outcome and decreasing miscarriage rate in hyperandrogenic polycystic ovary syndrome women: a randomized clinical trial.

The hyper androgenic status is a major complication of polycystic ovarian syndrome (PCOS) that deteriorates endometrial function and increases miscarriage rate. This study was conducted to investigate the efficacy of GnRH agonist before frozen-thawed embryo transfer in improving pregnancy outcome in infertile women with PCOS. This single-blind, randomized controlled trial was performed at Dr Shariati hospital and Omid Fertility Clinic in Tehran, Iran. In the study were included 178 PCOS women. Patients were then divided into two groups of control and intervention. All women received the standard treatment for the preparation of the endometrial using estradiol valerate at dose of 6-8 mg/day. The intervention group also received diphereline, as GnRH agonist, at two doses, 8 weeks before starting the endometrial preparation. Chemical pregnancy in intervention group was 47.7% compared to 35.6% in the control group, revealing no significant difference between two groups. No statistically significant difference was observed between two groups concerning clinical pregnancy rate (43.2% vs. 27.3%). However, rate of ongoing pregnancy was 42.0% in intervention group but 18.0% in the control group, suggesting a significant difference (P=0.001). The rate of miscarriage in the intervention group was 2.6% and in the control group was 33.3%, which was significantly lower (P=0.001). It can be concluded that endometrial preparation using GnRH improves ongoing pregnancy and decreases miscarriage rate. It seems that reduction of androgen level in PCOS patients affects the endometrium and improves the receptivity and implantation of the embryo, resulting in better pregnancy outcomes by reducing the miscarriage rate.

Hyperandrogenism and Metabolic Syndrome Are Associated With Changes in Serum-Derived microRNAs in Women With Polycystic Ovary Syndrome.

Polycystic ovary syndrome (PCOS) remains one of the most common endocrine disorder in premenopausal women with an unfavorable metabolic risk profile. Here, we investigate whether biochemical hyperandrogenism, represented by elevated serum free testosterone, resulted in an aberrant circulating microRNA (miRNAs) expression profile and whether miRNAs can identify those PCOS women with metabolic syndrome (MetS). Accordingly, we measured serum levels of miRNAs as well as biochemical markers related to MetS in a case-control study of 42 PCOS patients and 20 Controls. Patients were diagnosed based on the Rotterdam consensus criteria and stratified based on serum free testosterone levels (≥0.034 nmol/l) into either a normoandrogenic (n = 23) or hyperandrogenic (n = 19) PCOS group. Overall, hyperandrogenic PCOS women were more insulin resistant compared to normoandrogenic PCOS women and had a higher prevalence of MetS. A total of 750 different miRNAs were analyzed using TaqMan Low-Density Arrays. Altered levels of seven miRNAs (miR-485-3p, -1290, -21-3p, -139-3p, -361-5p, -572, and -143-3p) were observed in PCOS patients when compared with healthy Controls. Stratification of PCOS women revealed that 20 miRNAs were differentially expressed between the three groups. Elevated serum free testosterone levels, adjusted for age and BMI, were significantly associated with five miRNAs (miR-1290, -20a-5p, -139-3p, -433-3p, and -361-5p). Using binary logistic regression and receiver operating characteristic curves (ROC), a combination panel of three miRNAs (miR-361-5p, -1225-3p, and -34-3p) could correctly identify all of the MetS cases within the PCOS group. This study is the first to report comprehensive miRNA profiling in different subgroups of PCOS women with respect to MetS and suggests that circulating miRNAs might be useful as diagnostic biomarkers of MetS for a different subset of PCOS.

Serum miRNAs in women affected by hyperandrogenic polycystic ovary syndrome: the potential role of miR-155 as a biomarker for monitoring the estroprogestinic treatment

MicroRNAs can be used as very efficient circulating biomarkers. The role of microRNAs in polycystic ovary syndrome (PCOS) and the effects of antiandrogen therapy on microRNA expression is still not fully understood. A panel of serum microRNAs were retrotranscribed via looped reverse primer transcription specific for each miRNA and quantified via probe specific RT-PCR in 16 Caucasian hyperandrogenic PCOS women selected according to the Rotterdam criteria and in a subset of seven patients after four months of sequential reverse antiandrogenic therapy. All women recruited underwent an oral glucose tolerance test (OGTT) and a baseline total cholesterol, high density lipoproteins cholesterol, triglycerides, AST and ALT dosage. In the follicular phase women were evaluated for total testosterone, Δ4-androstenedione, DHEAS, 17OHpg, FSH, LH, and 17-β-E2. The AUC2hglucose, ISI Matsuda, oral disposition index (DIo) and visceral adipose index (VAI) were also calculated. We suggest that miR-155 might have a role as biomarker in hyperandrogenic PCOS patients to monitor the effect of antiandrogen therapy.

Using gonadotropin-releasing hormone agonist before frozen embryo transfer may improve ongoing pregnancy rates in hyperandrogenic polycystic ovary syndrome women

Polycystic ovary syndrome (PCOS), affecting more than 5–10% of woman at reproductive childbearing age, is characterized by anovulation and hyperandrogenism. Frozen-thawed embryo transfer (ET) has been widely used for PCOS women to minimize the risk of ovarian hyperstimulation syndrome. However, the hyperandrogenic status of PCOS women deteriorates endometrial function, which has subsequently increased miscarriage rates in PCOS women. Therefore, we conducted this retrospective study to compare the pregnancy outcomes of hyperandrogenic PCOS women with (n = 29) and without (n = 31, controls) pretreatment of gonadotropin-releasing hormone (GnRH) agonist before frozen-thawed ET. We found that pretreatment with GnRH agonist before frozen-thawed ETs could not significantly improve the clinical pregnancy rate in these hyperandrogenic PCOS women. However, the ongoing pregnancy rate was significantly increased in women with GnRH agonist pretreatment (odds ratio: 3.98, 95% confidence interval: 1.12–14.20, p = 0.033). We concluded that androgen deprivation status due to pretreatment with GnRH agonist might improve the ongoing pregnancy rate in hyperandrogenic PCOS women. Additional large, well-designed prospective studies are worthwhile and necessary.

Impact of PCOS on early embryo cleavage kinetics

This study investigated whether polycystic ovary syndrome (PCOS) affected early embryo development assessed by time-lapse analysis of embryo kinetics from fertilization to the blastocyst stage. This was a prospective cohort study of two pronuclei (2PN) embryos from 25 hyperandrogenic PCOS patients (110 2PN embryos), 26 normoandrogenic PCOS patients (140 2PN embryos) and 20 healthy, regularly cycling women (controls, 97 2PN embryos). Patients underwent the same baseline evaluation and the same ovarian stimulation from April 2010 to February 2013. Oocytes were fertilized by intracytoplasmic sperm injection and incubated in an EmbryoScope with pictures taken every 20min in seven focal planes. Time to 2PN breakdown, first cleavage and cleavage to 3, 4, 5, 6, 7 and 8 cells, morula and blastocyst (t2, t3, t4, t5, t6, t7, t8, tM, tB) were annotated. Differences in embryo kinetics between groups were assessed by mixed modelling. Compared with controls, embryos from hyperandrogenic PCOS patients were significantly delayed at 2PN breakdown, t2, t3, t4 and t7 but not at t5, t6, t8, tM or tB. Embryos from hyperandrogenic PCOS women had developed slower from fertilization to the 8-cell stage compared with embryos from controls.We investigated whether polycystic ovary syndrome (PCOS) affected early embryo development assessed by time-lapse analysis of embryo kinetics from fertilization to the blastocyst stage. This was a prospective cohort study of two pronuclei (2PN) embryos from 25 hyperandrogenic PCOS patients (110 2PN embryos), 26 normoandrogenic PCOS patients (140 2PN embryos) and 20 healthy, regularly cycling women (controls, 97 2PN embryos). Patients underwent the same baseline evaluation and the same ovarian stimulation from April 2010 to February 2013. Oocytes were fertilized by intracytoplasmic sperm injection and incubated in an EmbryoScope with pictures taken every 20min in seven focal planes. Time to 2PN breakdown, first cleavage, cleavage to 3, 4, 5, 6, 7 and 8 cells, morula and blastocyst (t2, t3, t4, t5, t6, t7, t8, tM, tB) were annotated. Differences in embryo kinetics between groups were assessed by mixed modelling. With mixed modelling, the ‘patient factor’ is adjusted for, as each patient contributed several embryos for analysis. Compared with embryos from controls, embryos from hyperandrogenic PCOS patients were significantly delayed at 2PN breakdown (P=0.0128), t2 (P=0.0061), t3 (P=0.0171), t4 (P=0.0017), t7 (P=0.04) and but not at t5, t6, t8, tM or tB. We concluded that embryos from hyperandrogenic PCOS women developed slower from fertilization to the 7-cell stage compared with embryos from controls. The clinical impact of the embryo delay was unknown, since this study was not powered to detect differences in implantation and pregnancy rates between groups.

Increased frequency of the DI genotype of the angiotensin-I converting enzyme and association of the II genotype with insulin resistance in polycystic ovary syndrome

The polycystic ovary syndrome (PCOS) is a common and complex disease with unclear pattern of inheritance, characterized by an androgen excess, while hyperinsulinemia and insulin resistance (IR) are common features of the syndrome. The angiotensin I converting enzyme (ACE) insertion (I)/deletion (D) gene polymorphism was proved to be involved in many pathophysiological conditions, including hypertension and IR. The purpose of this study was to evaluate the involvement of the ACE gene polymorphism in the pathogenesis of PCOS. In a case-control association study involving 801 PCOS women and 266 healthy controls, hormonal determinations and ACE polymorphism genotyping were performed. The PCOS women were classified into three groups: Group A presented biochemical hyperandrogenism, combined with anovulation and polycystic ovarian morphology; Group B, clinical hyperandrogenism combined with anovulation and polycystic ovarian morphology; and Group C, chronic anovulation and polycystic ovarian morphology. A significant increase in the frequency of the DI genotype of the ACE polymorphism was detected in PCOS women as a whole (P=0.035), in PCOS Group A (P=0.039) and Group B (P=0.010), while there was no difference in Group C (P=0.939). Significant difference was also observed in hyperandrogenic PCOS women as a whole (Group A+B) (P=0.017). The II genotype was positively correlated with HOMA-IR and QUICKI and with fasting insulin and glucose/insulin ratio in these groups. The association study of the ACE I/D polymorphism in PCOS women demonstrates an increase in the DI genotype incidence and an association of the II genotype with IR.

Metformin therapy increases insulin-like growth factor binding protein-1 in hyperinsulinemic women with polycystic ovary syndrome

Objectives: Polycystic ovary syndrome (PCOS) is associated with hyperandrogenism, insulin resistance, compensatory hyperinsulinemia, and increased levels of free insulin-like growth factor-I (IGF-I), presumably due to a decline in IGF binding protein 1 (IGFBP-1). This study was designed to evaluate effects of metformin therapy on serum levels of IGFBP-1 and IGF-I. Study design: Twenty-seven obese, hyperandrogenic PCOS women with elevated fasting insulin were treated for 12 weeks with metformin (500 mg p.o., t.i.d.). Serum levels of insulin, testosterone, sex hormone binding globulin (SHBG), IGF-I, and IGFBP-1 were measured before and after treatment. Body mass index (BMI) and waist-to-hip ratio (WHR) were assessed at baseline and at the end of therapy. Results: Metformin therapy significantly increased IGFBP-1 concentration by 38% ( P=0.05) but had no demonstrable effect on the total IGF-I levels. Fasting insulin levels declined by 38% ( P=0.0001) while the glucose/insulin ratio increased by 72% ( P=0.0001) and quantitative insulin sensitivity check index (QUICKI) increased by 8% ( P=0.0001). Metformin treatment also significantly decreased testosterone (by 37%, P=0.0001) and increased SHBG concentration (by 16%, P=0.04). Multiple linear regression analysis revealed that baseline IGFBP-1 levels correlated inversely and independently with two baseline parameters: WHR ( P=0.003) and free testosterone index ( P=0.04). Conclusions: The present study shows that metformin therapy not only restores normal levels of insulin and testosterone, but also decreases the pool of free-bioactive IGF-I by increasing the levels of circulating IGFBP-1. We provide further arguments in favor of metformin therapy in hyperinsulinemic women with PCOS.
