Combined oral contraceptives in the treatment of polycystic ovary syndrome

Gut Microbiota and Oral Contraceptive Use in Women with Polycystic Ovary Syndrome: A Systematic Review

Background: Polycystic ovary syndrome (PCOS) is one of the most prevalent endocrine syndromes affecting women at reproductive age. With increasing knowledge of the role of the microbiota in the pathogenesis of PCOS, new management strategies began to emerge. However, data on the impact of established treatment regimens, such as metformin and oral contraceptive agents, on the gut microbiota composition are scarce. This study aimed to evaluate the specificity of the gut microbiota in women with PCOS before and after treatment with oral contraceptives. Methods: We have systematically searched the following databases: PubMed/MEDLINE, Scopus, Web of Science and Google Scholar. The last search was performed on 13 May 2024. We included only full-text original research articles written in English. The risk of bias was assessed using a modified version of the Newcastle-Ottawa Scale. Results: The above described search strategy retrieved 46 articles. Additionally, 136 articles were identified and screened through Google Scholar. After removing duplicates, we screened the titles and abstracts, resulting in three eligible articles constituting the final pool. They were published between 2020 and 2022 and are based on three ethnically distinct study populations: Turkish, Spanish and American. The studies included a total of 37 women diagnosed with PCOS and using OCs. Conclusions: OC treatment does not seem to affect the gut microbiota in a significant way in patients with PCOS in short observation. Well-designed randomized controlled studies with adequate, unified sample size are lacking.

Exploring the therapeutic mechanisms of Yikang decoction in polycystic ovary syndrome: an integration of GEO datasets, network pharmacology, and molecular dynamics simulations

Objective

The incidence of Polycystic Ovary Syndrome (PCOS) is increasing annually. This study aims to investigate the therapeutic mechanisms of Yikang Decoction (YKD) in the treatment of PCOS through the integration of GEO datasets, network pharmacology, and dynamic simulation.

Methods

Active ingredients of YKD and their targets were collected from the Traditional Chinese Medicine Systems Pharmacology (TCMSP) platform. Disease-relevant targets for PCOS were retrieved from several databases, including GeneCards, OMIM, PharmGKB, DrugBank, and GEO. The underlying pathways associated with the overlapping targets between YKD and PCOS were identified using Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis. The mechanisms of interaction between the core targets and components were further explored through molecular docking and molecular dynamics simulations (MD).

Results

139 potential active components and 315 targets of YKD were identified. A topological analysis of the PPI network revealed 10 core targets. These targets primarily participated in the regulation of biological processes, including cell metabolism, apoptosis, and cell proliferation. The pathways associated with treating PCOS encompassed PI3K-Akt signaling pathway, Lipid and atherosclerosis, MAPK signaling pathways, and Endocrine resistance signaling pathways. Moreover, molecular docking and MD have been shown to reveal a good binding capacity between active compounds and screening targets.

Conclusion

This study systematically investigates the multi-target mechanisms of YKD in the treatment of PCOS, with preliminary verification provided through molecular docking and MD. The findings offer compelling evidence supporting the efficacy of YKD in treating PCOS.

Laser and Light-Based Therapies for Hirsutism Management in Women With Polycystic Ovarian Syndrome: A Systematic Review

Importance

Hirsutism represents a significant concern for women with polycystic ovary syndrome (PCOS), with deleterious psychological effects warranting acknowledgment and a clear imperative to provide effective management. To our knowledge, this is the first review to exclusively examine the effectiveness of laser and light-based therapies in addressing hirsutism in women with PCOS.

Objective

To synthesize the existing literature regarding the effectiveness of laser and light hair reduction therapies, either as stand-alone treatments or in combination with systemic agents, in treating hirsutism for women with PCOS.

Evidence Review

A systematic literature review was performed using MEDLINE, Embase, EMCARE, and CINAHL according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guidelines. Articles written in English, reporting on patients who met pre-established inclusion criteria were selected. Objective and subjectively measured outcomes relating to the effect of laser or light-based hair reduction therapies on hirsutism were abstracted. Heterogeneity among included studies precluded a meta-analysis, necessitating a narrative synthesis.

Findings

Six studies reporting data on 423 individual patients with PCOS who underwent laser or light-based hair reduction therapies were included: 4 randomized clinical trials and 2 cohort studies. Alexandrite laser demonstrated significant improvements in hirsutism severity and psychological outcomes, particularly at high-fluence application. Alexandrite laser was also found to be more effective than intense pulsed light (IPL). The combination of diode laser with either metformin or combined oral contraceptive pill was superior to the application of diode laser alone, just as the addition of metformin to IPL demonstrated superior results to IPL treatment alone. Overall, most interventions were well tolerated. The overall certainty of evidence across all outcomes and comparisons was limited in part due to the observational nature of some studies.

Conclusions and Relevance

This systematic review highlights the potential of laser and light hair reduction therapies, both as stand-alone treatments and in combination with other pharmacological agents in PCOS. However, this review was limited by low certainty of the evidence, few studies evaluating effectiveness and safety in those with skin of color, and heterogeneity in outcome assessment. Future studies are needed to provide more robust evidence among diverse individuals with PCOS and hirsutism.

Insights into Vitamin E with Combined Oral Contraceptive on INSR Gene in PCOS by Integrating In Silico and In Vivo Approaches

Polycystic ovarian syndrome (PCOS) is a hormone disorder common among reproductive-aged women. This is associated with the symptoms like an irregular menstrual cycle, excess androgens, and polycystic ovary. Interestingly, vitamin E acts like the hormone progesterone and improves insulin sensitivity in PCOS. The study aims to evaluate the therapeutic effect of vitamin E in combination with combined oral contraceptive (COC) against PCOS by in silico and in vivo methods. The therapeutic effect of vitamin E (25 and 50mg/kg) in combination with COC (0.4mg/kg) was screened by the in silico method using Auto dock vina 4.2.6. Additionally, in vivo studies with a letrozole-induced PCOS model were performed in 30 female SD rats (n = 6 in each group) for 8 weeks with different doses of vitamin E. Furthermore, histopathological features and the insulin receptor (INSR) gene were scrutinized. An in silico study showed that drospirenone and vitamin E have an excellent affinity to bind to INSR and have higher binding energy (- 8.5 kcal/mol and - 8.7 kcal/mol, respectively). In vivo results showed a significant reduction in elevated testosterone levels compared to that of the PCOS group; follicle-stimulating hormone (FSH) and insulin levels also showed significant changes and reversed anti-oxidant levels in a dose-dependent manner. Ovarian histopathological changes were observed in different follicle counts in addition to the INSR gene, which showed changes in densitometry values. Supplementation of vitamin E combined with COC could be effective against PCOS, and clinical studies must be carried out further.

Symptoms of mental disorders and oral contraception use: A systematic review and meta-analysis

Worldwide, over 150 million adolescent and adult women use oral contraceptives (OC). An association between OC-use and the emergence of symptoms of mental disorders has been suggested. This systematic review and meta-analysis provide an overview of published research regarding symptoms of mental disorders in association with OC-use, factoring the influence of OC types, age of first-use, duration of OC-intake, and previous diagnoses of mental disorders. A systematic literature search was conducted between June-July 2022. 22 studies were included. While most found no significant OC-use effects on mental symptoms, some hinted at OCs as a potential risk. The existing evidence regarding the potential link between progestin-only OC-use and an elevated risk of mental symptoms in comparison to combined OC-use remains inconclusive. However, due to emerging indications suggesting that the formulation of OC might play a role in mental health outcomes, this topic warrants further investigation. Moreover, indications of an increased risk for depressive symptoms in adolescent OC-users should be noted. Hence, while general population effects seem unlikely, they cannot be completely disregarded. The decision on OC-use should depend on the patient's medical history and should be re-evaluated regularly.

Nanocomposites based on nanoceria regulate the immune microenvironment for the treatment of polycystic ovary syndrome

The immune system is closely associated with the pathogenesis of polycystic ovary syndrome (PCOS). Macrophages are one of the important immune cell types in the ovarian proinflammatory microenvironment, and ameliorate the inflammatory status mainly through M2 phenotype polarization during PCOS. Current therapeutic approaches lack efficacy and immunomodulatory capacity, and a new therapeutic method is needed to prevent inflammation and alleviate PCOS. Here, octahedral nanoceria nanoparticles with powerful antioxidative ability were bonded to the anti-inflammatory drug resveratrol (CeO2@RSV), which demonstrates a crucial strategy that involves anti-inflammatory and antioxidative efficacy, thereby facilitating the proliferation of granulosa cells during PCOS. Notably, our nanoparticles were demonstrated to possess potent therapeutic efficacy via anti-inflammatory activities and effectively alleviated endocrine dysfunction, inflammation and ovarian injury in a dehydroepiandrosterone (DHEA)-induced PCOS mouse model. Collectively, this study revealed the tremendous potential of the newly developed nanoparticles in ameliorating the proinflammatory microenvironment and promoting the function of granulosa cells, representing the first attempt to treat PCOS by using CeO2@RSV nanoparticles and providing new insights in combating clinical PCOS.

A Systematic Review of the Psychosocial Impact of Polycystic Ovarian Syndrome Before and After Treatment

While polycystic ovarian syndrome (PCOS) is one of the most common hormonal endocrine disorders among women of reproductive age, the psychosocial impact of PCOS has not been evaluated across different quality of life (QoL) indicators. We rigorously analyzed available evidence pertaining to the psychosocial burden of PCOS in women of reproductive age and compared validated QoL scores of women with and without PCOS before and after treatment. We searched and considered publications from PubMed, PsychINFO, Embase, and Cochrane Library that evaluated the association between diagnosed PCOS and QoL by standardized and validated questionnaires at baseline and after treatment. Reviewers assessed the risk of bias using established Cochrane and Newcastle-Ottawa Scale guidelines. A total of 33 studies were included in the review: 14 randomized controlled trials and 19 observational studies. The 36-Item Short Form Survey and World Health Organization Quality of Life - BREF questionnaire both revealed that the diagnosis and life experience of PCOS had a disability score that was similar to or surpassed that of heart disease, diabetes mellitus, or breast cancer. QoL scores, associated with mental health issues, infertility, sexual dysfunction, obesity, menstrual disorder, and hirsutism, were lower at the baseline than after treatment in the majority of instruments measuring these variables in women with PCOS. PCOS is associated with significant psychosocial stress and reduced QoL across baseline measures and in comparison, to other diseases. Evidence suggests that treatment with therapy, medications, and lifestyle management decreased psychosocial burdens and alleviated QoL experienced by women with PCOS.

Quantitative risk-benefit profiles of oral contraceptives, insulin sensitizers and antiandrogens for women with polycystic ovary syndrome: A model-based meta-analysis

Oral contraceptives (OCs), insulin sensitizers, and antiandrogens (AAs), alone or in combination, are commonly used for treating non-fertility indications in polycystic ovary syndrome (PCOS). However, unclear risk-benefit profiles jeopardize their appropriate clinical applications. This study aimed to quantitatively evaluate the effects of the aforementioned medications and to compare their risk-benefit profiles. Randomized controlled trials published until 14th March 2022 were searched in PubMed and Embase. A model-based meta-analysis was developed to examine the time-effect profiles of each medication. The maximal percentage change of the effect (Emax) and time to achieve half of Emax (T50) were estimated. Primary outcomes included menstruation, hirsutism score, free androgen index (FAI), body mass index (BMI), insulin sensitivity, and lipid profiles. Overall, 200 studies (9,685 patients and 385 arms) were identified for modeling. OCs performed exceptionally well in improving menstruation (Emax: 149%; T50: 7.44 weeks), hirsutism score (Emax: 66.2%; T50: 26.2 weeks), and FAI (Emax: 75.7%; T50: 0.51 weeks). However, OCs elevated the triglyceride (TG) level (Emax: 12.6%; T50:1.19 weeks). After 12-week OC treatment, the TG level of approximately 30% of patients, whose baselines were normal, exceeded the reference limit. This suggested that OC-induced dyslipidemia should be routinely monitored. The maximal BMI-lowering effect of metformin was similar to that of placebo (Emax: 3.80%); however, metformin had a shorter T50 (6.67 weeks versus 12.9 weeks). Further, active lifestyle intervention plus placebo significantly decreased BMI (Emax: 8.78%). Adding metformin to active lifestyle intervention accelerated the BMI-lowering effect within 24 weeks, whereas with the extension of this addition beyond 24 weeks, BMI did not reduce further, which indicated that benefits were limited from this prolonged addition. AAs were less potent in reducing hirsutism score (Emax: 40.2% versus 66.2%) and FAI (Emax: 34.5% versus 75.7%) compared to OCs. OC plus metformin combined OC-derived androgen-suppressing effects and metformin-derived insulin-sensitizing effects, and partially relieved the OC-induced TG increase (Emax: 9.76%). Baseline dependency was found in most clinical responses, implying that pharmacotherapies tailored based on baselines achieved more clinical improvements. This study presents new quantitative evidence on pharmacotherapies for PCOS. Currently, long-term risk-benefit profiles and emerging therapies are inadequately reported and require more further research.

Beneficial Effects of a Novel Fenugreek Seed Extract (Trigonella foenum-graecum, Furocyst®) in Women with Polycystic Ovary Syndrome (PCOS): A Follow-up Compliance Clinical Investigation

INTRODUCTION

Polycystic Ovary Syndrome (PCOS) is an endocrine disorder which accounts for infertility around the world. The disease is characterized by elevated secretion of androgens in the women which results in enlargement of ovaries with accumulation of fluid filled cysts, irregular menstrual cycles, and hirsutism. This study reports the efficacy of a patented, standardized Trigonella foenum-graecum extract (Furocyst®) as an effective phytotherapeutic for effective management of PCOS.

OBJECTIVE

This randomized one-arm study assessed the efficacy of Furocyst® in 107 female volunteers over a period of 12 consecutive weeks.

METHOD

Following approvals of the Institutional Ethical Committee and clinicaltrials.gov, 107 female volunteers (age: 18-45 years) were recruited. Subjects consumed Furocyst® capsules (1,000 mg/day p.o.) over a period of 12 consecutive weeks. Physical (Sonographic scan, Hirsutism Score, Menstrual cycle, Body Weight, BMI, Height, Waist Circumference and Blood Pressure) and biochemical parameters (LH/FSH ratio, TSH, Prolactin, Fasting insulin, Fasting Glucose, triglyceride, cholesterol, HOMA Index, free and total testosterone, 2-hour GTT, DHEAS) were assessed at the beginning of the study as well as at intervals of 4 weeks till 12 weeks to determine the efficacy of Furocyst® on PCOS induced damage on reproductive and endocrine system.

RESULTS

Furocyst® treatment induced >40% reduction of mean cyst sizes in both ovaries with corresponding reduction of in ovarian volumes. LH:FSH ratio was also significantly improved with corresponding reduction in total testosterone and prolactin levels. As a result of improvement in endocrine function, menstrual cycle became regular in the subjects. Furocyst® also reduced the severity of other associated ailments such as insulin resistance, dyslipidemia, and improved liver function significantly.

CONCLUSIONS

This study reinstated the efficacy of Furocyst® as a safe phytotherapeutic to reverse the effects of PCOS inflicted damage on the female reproductive system without any adverse events.

Association between preconception anti-androgen therapy and pregnancy outcomes of patients with PCOS: A prospective cohort study

BACKGROUND

Polycystic ovary syndrome (PCOS) not only increases fertility challenges for women of reproductive age, but also leads to increased complications during pregnancy and even affects the birth weight of newborns. Also, hyperandrogenemia is associated with lower pregnancy rates and lower live birth rates and may even play a role in preterm delivery and pre-eclampsia in patients with PCOS. However, it is still controversial whether PCOS patients are treated with androgen-lowering therapy before pregnancy.

OBJECTIVE

To assess the effect of anti-androgen therapy prior to ovulation induction on maternal and infant pregnancy outcomes in patients with PCOS.

METHODS

Prospective cohort study.

RESULTS

A total of 296 patients with PCOS were enrolled in the study. The prevalence of adverse pregnancy outcomes, and neonatal complications was lower in DRSP(with drospirenone ethinyl estradiol tablets (II) pretreatment) group than in NO-DRSP(without drospirenone ethinyl estradiol tablets (II) pretreatment) groups (DRSP vs. NO-DRSP: adverse pregnancy outcomes, 12.16% vs. 27.03%, P=0.001; neonatal complications, 17.16% vs. 36.67%, P<0.001). No significant difference was found in maternal complications. Further subgroup analysis revealed that PCOS with pretreatment decreased the risk of preterm delivery (2.99% vs. 10.00%; Adjusted RR, 3.80; 95% CI, 1.19-12.13), pregnancy loss (9.46% vs. 18.92%; Adjusted RR, 2.07; 95% CI, 1.08-3.96), low birth weight (0.75% vs 7.50%; Adjusted RR, 12.08; 95% CI, 1.50-97.31), fetal malformations(1.49% vs. 8.33%; Adjusted RR, 5.63; 95% CI, 1.20-26.33).There were no significant differences in the incidence of DM and PIH as pregnancy complications between the two groups (P>0.05).

CONCLUSION

Our findings suggest that preconception androgen-lowering therapy in patients with PCOS improves pregnancy outcomes and reduces neonatal complications.

Progesterone Actions and Resistance in Gynecological Disorders

Estrogen and progesterone and their signaling mechanisms are tightly regulated to maintain a normal menstrual cycle and to support a successful pregnancy. The imbalance of estrogen and progesterone disrupts their complex regulatory mechanisms, leading to estrogen dominance and progesterone resistance. Gynecological diseases are heavily associated with dysregulated steroid hormones and can induce chronic pelvic pain, dysmenorrhea, dyspareunia, heavy bleeding, and infertility, which substantially impact the quality of women's lives. Because the menstrual cycle repeatably occurs during reproductive ages with dynamic changes and remodeling of reproductive-related tissues, these alterations can accumulate and induce chronic and recurrent conditions. This review focuses on faulty progesterone signaling mechanisms and cellular responses to progesterone in endometriosis, adenomyosis, leiomyoma (uterine fibroids), polycystic ovary syndrome (PCOS), and endometrial hyperplasia. We also summarize the association with gene mutations and steroid hormone regulation in disease progression as well as current hormonal therapies and the clinical consequences of progesterone resistance.

Effect of Sex Hormone-Binding Globulin on Polycystic Ovary Syndrome: Mechanisms, Manifestations, Genetics, and Treatment

Polycystic ovary syndrome (PCOS) is one of the most common endocrine diseases causing infertility in women of childbearing age. It is characterized by hyperandrogenemia (HA), chronic anovulation, and polycystic ovary morphology (PCOM). Most women with PCOS have metabolic abnormalities. Sex hormone-binding globulin (SHBG), a transport carrier that binds estrogen and androgens and regulates their biological activity, is usually used as an indicator of hyperandrogenism in women with PCOS. Low serum SHBG levels are considered a biomarker of metabolic abnormalities and are associated with insulin resistance (IR), HA, and abnormal glucose and lipid metabolism in PCOS patients. SHBG is also related to the long-term prognosis of PCOS, whereas SHBG gene polymorphism is associated with PCOS risk. In addition, the administration of metformin (MET), glucagon-like peptide-1 receptor agonists (GLP-1 RAs), thiazolidinediones (TZDs), compound oral contraceptives (COCs), as well as nutrient supplements such as inositol (MI), vitamin D, and synbiotics can regulate SHBG levels to ameliorate PCOS complications and improve prognosis. This review focuses on the interaction between SHBG and various PCOS complications as well as the regulation of SHBG by various drugs and nutrients and its therapeutic effects on PCOS.

The Contraindications to Combined Oral Contraceptives among Reproductive-Aged Women in an Obstetrics and Gynaecology Clinic: A Single-Centre Cross-Sectional Study

This study aimed to determine the estimated proportion of contraindications among women taking combined oral contraceptives (COCs) and to assess the risk factors associated with their contraindications. This study was cross-sectional. Reproductive-aged women (18–49 years) on any COCs between 2018 and 2020 were recruited from one obstetrics–gynaecology clinic in a university-affiliated hospital and were included. Contraindications were defined using the World Health Organization (WHO) Medical Eligibility Criteria (MEC) for Contraceptive Use. Data were collected from electronic medical records for all included women, as well as a standardised, pretested, structured survey for one-third of the women. In this cross-sectional study, 380 women using COCs were included. Their mean age was 31.645 ± 7.366 years. Among them, 131 (34.5%) participated via a survey and electronic records, while the other 249 (65.5%) participated via electronic records only. The majority of the participants had a Bachelor’s degree (59.0%) and were married (62.1%). The overall estimated proportion of patients with at least one contraindication to COCs according to category 3 (relative contraindications) or 4 (absolute contraindications) was 31.3% (95% CI 26.63–35.99). The most common contraindications observed were controlled hypertension, category 3 (12.1%); major surgery with prolonged immobilisation, category 4 (4.7%); migraine with aura at any age, category 4 (4.2%); breastfeeding from six weeks to less than six months postpartum, category 3 (4.0%); and diabetes mellitus with complications, category 4 (3.2%). Significant factors associated with contraindications to COCs were married women (OR 2.19, 95% CI 1.38–3.46), those aged 35 years or more (OR 2.33, 95% CI 1.49–3.66), and those with one or more live births (OR 2.19, 95% CI 1.38–3.46). Ensuring proper assessment prior to prescribing and considering alternatives suitable for long-term use among women taking an oral contraceptive regularly is recommended.

Management of cardiometabolic complications in polycystic ovary syndrome: Unmet needs

Polycystic ovary syndrome (PCOS) is the most common endocrine disorder and the most common cause of androgen excess in reproductive-age women. The heterogeneity of the clinical presentation in PCOS patients suggests the involvement of multiples abnormal physiological pathways. In addition, women with PCOS have a high prevalence of cardiometabolic risk factors. Unfortunately, limited effective evidence-based therapeutic agents are available to treat the cardiometabolic complications in PCOS patients. Insights from recent studies highlight the multiple opportunities to deliver timely effective medical care for women with PCOS. This perspective manuscript aims to highlight the unmet need for effective and safe management of the cardiometabolic complications in PCOS patients.

A comparison of the effects of oral contraceptives on the clinical and biochemical manifestations of polycystic ovary syndrome: a crossover randomized controlled trial

STUDY QUESTION

Do oral contraceptives (OCs) containing progestins with low androgenic or antiandrogenic activities have different effects to those containing levonorgestrel (LNG) on clinical, androgenic and metabolic manifestations of polycystic ovarian syndrome (PCOS)?

SUMMARY ANSWER

The three OCs tested had similar effects on clinical findings of hyperandrogenism (HA), whereas products containing LNG were less effective on androgenic profiles and had detrimental effects on lipid profiles.

WHAT IS KNOWN ALREADY

Despite data available on the effects of OCs, the superiority of products with low androgenic or antiandrogenic progesterone components in comparison with older products used in women with PCOS has not been clarified.

STUDY DESIGN, SIZE, DURATION

This study is a crossover randomized controlled six-arm trial, with all six arms including two 6-month treatment periods, one period with OCs containing LNG, and the other with one of three OCs containing desogestrel (DSG), cyproterone acetate (CPA) or drospirenone (DRSP). The trial was conducted between February 2016 and January 2018 and enrolled 200 patients with PCOS.

PARTICIPANTS/MATERIALS, SETTING, METHODS

Two hundred women with PCOS (ages 18-45 years) were recruited at the endocrine outpatient clinic of the Research Institute for Endocrine Sciences (RIES) of the Shahid Beheshti University of Medical Sciences, Tehran, Iran. A blocking or stratification random allocation (block size = 6) using a computer-based random number generator was prepared to assign participants to treatment groups. Both the clinical examiner and data analyst were blinded to participants during the trial. Outcomes of interest, including anthropometric and clinical manifestations and hormonal, and biochemical parameters were assessed at baseline, after 3 and 6 months of each treatment and after the washout period.

MAIN RESULTS AND THE ROLE OF CHANCE

This study detected a higher decrease in free-androgen index (FAI) levels after 3 months of treatment with OCs containing DSG (95% CI: -2.3, -1.0), CPA (95% CI: -2.4, -1.1) and DRSP (95% CI: -2.6, -1.4), compared with products containing LNG (P < 0.001). Use of OCs containing DSG (95% CI: -3.6, -1.5), CPA (95% CI: -3.1, -0.8) and DRSP (95% CI: -3.4, -1.1) for 6 months was associated with more decrease in FAI, compared with products containing LNG (P < 0.001). The study showed that use of OCs containing DSG, CPA and DRSP for 3-6 months was associated with a higher increase of sex hormone-binding globulin (SHBG), compared with products containing LNG (P < 0.001). We also observed more decrease in dehydroepiandrosterone sulfate levels after use of OCs containing DSG (P = 0.003), CPA (P = 0.012) and DRSP (P < 0.001) for 6 months, compared with products containing LNG. Our results showed that the use of OCs containing DRSP for 6 months was associated with more improvement in acne, compared with products containing LNG (P = 0.007). Women treated with OCs containing CPA, and DRSP for 3 months had higher TG and HDL levels and lower LDL levels, compared with those treated with products containing LNG (P < 0.05). After 6 months of treatment, patients treated with OCs containing DRSP had a sharper decline in LDL levels and more increase in HDL levels, compared to those treated with products containing LNG (P = 0.001).

LIMITATIONS, REASONS FOR CAUTION

Considering this trial was conducted in women diagnosed with Androgen Excess Society criteria, the results may not be generalizable for mild phenotypes diagnosed using Rotterdam criteria. Other limitations of the study include the high dropout rate, the lack of a gold standard androgen assay and the multiple end points.

WIDER IMPLICATIONS OF THE FINDINGS

Our results support the views of clinicians, who suggest an OC with a low androgenic or antiandrogenic progestin, if available, to treat PCOS.

STUDY FUNDING/COMPETING INTEREST(S)

Estrogen-progestin oral contraceptive and nicotine exposure synergistically confers cardio-renoprotection in female Wistar rats

Approximately fifty percent of premenopausal women who smoke cigarettes or on nicotine replacement therapy are also on hormonal contraceptives, especially oral estrogen-progestin. Oral estrogen-progestin therapy has been reported to promote insulin resistance (IR) which causes lipid influx into non-adipose tissue and impairs Na⁺/K⁺ -ATPase activity, especially in the heart and kidney. However, the effects of nicotine on excess lipid and altered Na⁺/K⁺ -ATPase activity associated with the use of estrogen-progestin therapy have not been fully elucidated. This study therefore aimed at investigating the effect of nicotine on cardiac and renal lipid influx and Na⁺/K⁺ -ATPase activity during estrogen-progestin therapy. Twenty-four female Wistar rats grouped into 4 (n = 6/group) received (p.o.) vehicle, nicotine (1.0 mg/kg) with or without estrogen-progestin steroids (1.0 μg ethinyl estradiol and 5.0 μg levonorgestrel) and estrogen-progestin only daily for 6 weeks. Data showed that estrogen-progestin treatment or nicotine exposure caused IR, hyperinsulinemia, increased cardiac and renal uric acid, malondialdehyde, triglyceride, glycogen synthase kinase-3, plasminogen activator inhibitor-1, reduced bilirubin and circulating estradiol. Estrogen-progestin treatment led to decreased cardiac Na⁺/K⁺-ATPase activity while nicotine did not alter Na⁺/K⁺-ATPase activity but increased plasma and tissue cotinine. Renal Na⁺/K⁺-ATPase activity was not altered by the treatments. However, all these alterations were reversed following combined administration of oral estrogen-progestin therapy and nicotine. The present study therefore demonstrates that oral estrogen-progestin therapy and nicotine exposure synergistically prevents IR-linked cardio-renotoxicity with corresponding improvement in cardiac and renal lipid accumulation, oxidative stress, inflammation and Na⁺/K⁺-ATPase activity.

Polycystic ovary syndrome (PCOS) and adolescence: How can we manage it?

Polycystic Ovary Syndrome is a very complex syndrome, with typical hormonal and metabolic features. In adolescent girls, this condition shows particular characteristics which are in common with adult sign and symptoms, often making the diagnosis difficult. On the other side, treatment strategy aims to manage the different aspects of this syndrome, and is generally based on lifestyle/diet modifications possibly associated with use of estroprogestins, anti-androgens and insulin-sensitizing agents. In this article, we will briefly review both diagnosis and clinical approach to polycystic ovary syndrome in adolescence which still remain a matter of debate in view of the peculiar hormonal milieu of that critical period.

A comprehensive review of clinical studies with herbal medicine on polycystic ovary syndrome (PCOS)

BACKGROUND

Polycystic ovary syndrome (PCOS) is a frequent medical condition characterized by both metabolic and reproductive disorders. Different pharmaceutical treatments have been proposed for PCOS. However, side effects of long-term treatments and their probable low efficacy have made complementary and alternative treatments a valuable option. Recent reports have indicated the increased use of complementary treatments. Herbal medicine, as part of complementary medicine, was find introduced in traditional Persian and Chinese medicine. Medicinal herbs have used for a long time in the treatment of gynecological and infertility problems of PCOS patients. In this study, we aimed to review herbal medicines used for PCOS worldwide.

METHODS

PubMed, Embase, Cochrane, and Scopus databases were searched for clinical trials and Randomized Controlled Trials based on related keywords. Data were collected from 1990 to 2019.

RESULTS

According to a multitude of studies, a wide spectrum of herbs can be used to improve various aspects of PCOS. Herbs such as Cinnamomum verum, Trigonella foenum-graecum L., and Vitex agnus-castus can impact on menstrual and ovulatory dysfunctions, obesity, insulin resistance, lipid-metabolism dysfunction, and androgen excess-related conditions.

CONCLUSION

Some plants as natural remedies may have beneficial effects on improving different aspects of PCOS; but further studies are needed to investigate their mechanisms and safety.

Polycystic ovary syndrome: An update

Polycystic ovary syndrome (PCOS) is a common endocrine disorder. Patients may present with a combination of hyperandrogenism symptoms, menstrual irregularities, metabolic syndrome, infertility, acne, and obesity. PCOS diagnosis is based on three diagnostic guidelines. Treatment options include oral contraceptive pills, antiandrogens, and metformin.

Uterine progesterone signaling is a target for metformin therapy in PCOS-like rats

Impaired progesterone (P4) signaling is linked to endometrial dysfunction and infertility in women with polycystic ovary syndrome (PCOS). Here, we report for the first time that elevated expression of progesterone receptor (PGR) isoforms A and B parallels increased estrogen receptor (ER) expression in PCOS-like rat uteri. The aberrant PGR-targeted gene expression in PCOS-like rats before and after implantation overlaps with dysregulated expression of Fkbp52 and Ncoa2, two genes that contribute to the development of uterine P4 resistance. In vivo and in vitro studies of the effects of metformin on the regulation of the uterine P4 signaling pathway under PCOS conditions showed that metformin directly inhibits the expression of PGR and ER along with the regulation of several genes that are targeted dependently or independently of PGR-mediated uterine implantation. Functionally, metformin treatment corrected the abnormal expression of cell-specific PGR and ER and some PGR-target genes in PCOS-like rats with implantation. Additionally, we documented how metformin contributes to the regulation of the PGR-associated MAPK/ERK/p38 signaling pathway in the PCOS-like rat uterus. Our data provide novel insights into how metformin therapy regulates uterine P4 signaling molecules under PCOS conditions.

Comparing the Effects of Combined Oral Contraceptives Containing Progestins With Low Androgenic and Antiandrogenic Activities on the Hypothalamic-Pituitary-Gonadal Axis in Patients With Polycystic Ovary Syndrome: Systematic Review and Meta-Analysis

Background

Different products of combined oral contraceptives (COCs) can improve clinical and biochemical findings in patients with polycystic ovary syndrome (PCOS) through suppression of the hypothalamic-pituitary-gonadal (HPG) axis.

Objective

This systematic review and meta-analysis aimed to compare the effects of COCs containing progestins with low androgenic and antiandrogenic activities on the HPG axis in patients with PCOS.

Methods

We searched PubMed, Scopus, Google Scholar, ScienceDirect, and Web of Science databases (1980-2017) to identify randomized controlled trials or nonrandomized studies investigating the effect of COCs containing progestins with low androgenic and antiandrogenic activities, including the products containing desogestrel, cyproterone acetate, and drospirenone, on the HPG axis in patients with PCOS. In this meta-analysis, fixed and random effect models were used. Outcomes of interest were weighted mean differences (WMD) of hormonal parameters, including the follicle-stimulating hormone (FSH), luteinizing hormone (LH), LH-to-FSH ratio, estradiol, total testosterone, and sex hormone–binding globulin. Potential sources of heterogeneity were investigated using meta-regression and subgroup analyses. Subgroup analyses were performed based on the used progestin compound and treatment duration. We assessed quality of included studies and their risk of bias using Cochrane guidelines. Publication bias was assessed using Egger test and funnel plot.

Results

COC use was significantly associated with a decrease in gonadotropin levels, including FSH and LH. Use of products containing cyproterone acetate was associated with a decrease in FSH levels after 3 months (WMD=−0.48; 95% CI −0.81 to −0.15), 6 months (WMD=−2.33; 95% CI −3.48 to −1.18), and 12 months (WMD=−4.70; 95% CI −4.98 to −4.42) and a decrease in LH levels after 3 months (WMD=−3.57; 95% CI −5.14 to −1.99), 6 months (WMD=−5.68; 95% CI −9.57 to −1.80), and 12 months (WMD=−11.60; 95% CI −17.60 to −5.60). Use of COCs containing drospirenone for 6 months decreased FSH (WMD=−0.93; 95% CI −1.79 to −0.08) and LH (WMD=−4.59; 95% CI −7.53 to −1.66) levels. Data for products containing desogestrel were few, but this compound generally had no statistically significant influence on gonadotropin levels similar to that observed with COCs containing cyproterone acetate and drospirenone. Use of COCs was not associated with any significant change in LH-to-FSH ratio. COCs containing cyproterone acetate showed maximum effect on gonadotropin suppression. COCs containing cyproterone acetate significantly decreased estradiol concentrations, whereas those containing drospirenone exhibited no such effect. All COCs demonstrated improvement in androgenic profile and had the same effects on total testosterone and sex hormone–binding globulin concentrations. Progestin compound and treatment duration had no statistically significant effects on changing total testosterone and sex hormone–binding globulin levels.

Conclusions

COCs containing cyproterone acetate can effectively suppress gonadotropins, leading to a decrease in androgenic parameters. Although different products of COCs could significantly suppress the androgenic profile, it seems that products containing cyproterone acetate are more effective in suppressing gonadotropin and estradiol levels in patients with PCOS.

High level of C-type natriuretic peptide induced by hyperandrogen-mediated anovulation in polycystic ovary syndrome mice

Polycystic ovary syndrome (PCOS), which is characterized by hyperandrogenism, is a complex endocrinopathy that affects the fertility of 9-18% of reproductive-aged women. However, the exact mechanism of PCOS, especially hyperandrogen-induced anovulation, is largely unknown to date. Physiologically, the natriuretic peptide type C/natriuretic peptide receptor 2 (CNP/NPR2) system is essential for sustaining oocyte meiotic arrest until the preovulatory luteinizing hormone (LH) surge. We therefore hypothesized that the CNP/NPR2 system is also involved in PCOS and contributes to arresting oocyte meiosis and ovulation. Here, based on a dehydroepiandrosterone (DHEA)-induced PCOS-like mouse model, persistent high levels of CNP/NPR2 were detected in anovulation ovaries. Meanwhile, oocytes arrested at the germinal vesicle stage correlated with persistent high levels of androgen and estrogen. We further showed that ovulation failure in these mice could be a result of elevated Nppc/Npr2 gene transcription that was directly increased by androgen (AR) and estrogen (ER) receptor signaling. Consistent with this, anovulation was alleviated by administration of either exogenous human chorionic gonadotropin (hCG) or inhibitors of AR or ER to reduce the level of CNP/NPR2. Additionally, the CNP/NPR2 expression pattern in the anovulated follicles was, to some extent, consistent with the clinical expression in PCOS patients. Therefore, our study highlights the important role an overactive CNP/NPR2 system caused by hyperandrogenism in preventing oocytes from maturation and ovulation in PCOS mice. Our findings provide insight into potential mechanisms responsible for infertility in women with PCOS.

Contemporary approaches to the management of polycystic ovary syndrome

Polycystic ovary syndrome (PCOS) is a common disorder in women in their reproductive years and is characterized by androgen excess, ovulatory dysfunction, and polycystic ovarian morphology. It is also associated with several metabolic abnormalities, particularly insulin resistance and obesity, which play an important role in the pathophysiology of PCOS and, in particular, negatively influence ovarian function and fertility. This review article summarizes the available treatment for women with PCOS. Specifically, current and potentially new therapies are discussed.

Effects of combined oral contraceptives on the clinical and biochemical parameters of hyperandrogenism in patients with polycystic ovary syndrome: a systematic review and meta-analysis

INTRODUCTION

Nowadays, selection of COCs with maximum antiandrogenic effects is one the main issues in treatment of women with polycystic ovary syndrome (PCOS).

OBJECTIVE

This systematic review and meta-analysis aimed to compare the effects of COCs on the clinical and biochemical parameters of hyperandrogenism (HA) in patients with PCOS.

METHODS

Electronic databases (PubMed, Scopus, ScienceDirect and web of science) were searched from 1987 to November 2015 to identify clinical trials investigating effect of the various COCs on the clinical and biochemical parameters of HA in patients. In this meta-analysis, both fixed and random effect models were used. Potential sources of heterogeneity were explored by meta-regression and subgroup analyses.

RESULTS

Findings showed that COC use for 3-12 months was significantly associated with an increase in sex hormone-binding globulin (SHBG) levels and a decrease in Ferriman-Gallwey (FG) score, total testosterone (TT), free testosterone (FT), androstenedione (A4) and dehydroepiandrosterone sulphate (DHEAS) levels. Type of progestin or duration of treatment had no important effects on declining androgen levels. Long-term use of COCs (6-12 months) was more effective in improving hirsutism, compared to short term. COCs containing cyproterone acetate (CPA) for 12 months had the strongest effect in improving hirsutism.

CONCLUSIONS

This study shows that, in patients with PCOS, COCs can effectively improve biochemical and clinical parameters of HA. All COCs studies have similar effects on the hormonal profiles of these patients, and products containing CPA may be an effective treatment in hirsute patients with PCOS.

Ovarian angiogenesis in polycystic ovary syndrome

Polycystic ovary syndrome (PCOS) is the most prevalent endocrine pathology among women in reproductive age. Its main symptoms are oligo or amenorrhea, hyperandrogenism and the presence of ovarian cysts. It is also associated with infertility, obesity and insulin resistance. Mainly due to its heterogeneity, PCOS treatments are directed to manage its symptoms and to prevent associated diseases. The correct formation and regression of blood vessels during each ovarian cycle is indispensable for proper follicular development, ovulation and corpus luteum formation. The importance of these processes opened a new and promising field: ovarian angiogenesis. Vascular alterations characterize numerous pathologies, either with increased, decreased or abnormal angiogenesis. In the last years, several anomalies of ovarian angiogenesis have been described in women with PCOS. Therefore, it has been suggested that these alterations may be associated with the decreased - or lack of - ovulation rates and for the formation of cysts in the PCOS ovaries. Restoration of a proper vessel formation in the ovaries may lead to improved follicular development and ovulation in these patients. In the present review, we attempt to summarize the alterations in ovarian angiogenesis that have been described in women with PCOS. We also discuss the therapeutic approaches aimed to correct these alterations and their beneficial effects on the treatment of infertility in PCOS.

Risks, benefits size and clinical implications of combined oral contraceptive use in women with polycystic ovary syndrome

BACKGROUND

Polycystic ovary syndrome (PCOS) is a complex condition with high risk for dyslipidemia, dysglycemia, venous thromboembolism, cardiovascular disease and metabolic syndrome. Because the combined oral contraceptive (COC) use has also been associated with impaired fasting glucose, insulin resistance and increased risk of thromboembolism disease, it is rationale to think that the combination of oral contraceptive and PCOS could make it worse or increase the risks.

OBJECTIVE

To examine the current data regarding potential additional risks and benefits of contraceptive use, highlights the major gap in knowledge for designing future studies and, when possible, suggests an adequate COC formulation for a determined PCOS phenotype.

METHODS

English-language publications reporting on the influence of COCS in the development of venous thromboembolism in PCOS patients published until 2017 were searched using PubMed, Cochrane database, and hand search of references found in consulted articles. Ranges of collected data are given; the pooled data are presented as median and first and third quartiles. Wilcoxon signed-ranks test for paired samples was used to compare before-after original data. P value was set at 0.05.

RESULTS

Most of COCs preparations significantly decrease androgens, and increase sex-hormone binding globulin. Therefore, the benefits of COCs are clear in patients with proved hyperandrogenemia. Regarding the impact of COCs on carbohydrate metabolism of PCOS subjects, the data were inconsistent but they tended to show no additional risk. Regarding lipids, most COCs consistently increased high-density lipoprotein cholesterol, triglycerides and total cholesterol concentrations but the clinical implications of these changes need additional studies.

CONCLUSION

The review showed consistent beneficial effect of COCs, particularly for hyperandrogenemic PCOS patients. The benefit size of COC's use by normoandrogenemic PCOS patients is uncertain and need more investigation. The effects of COC use on carbohydrate metabolism of women with PCOS are still unresolved since most studies are observational but the current results demonstrated that COCs do not make their levels worse and may improve insulin sensitivity. The impact of COCs on lipids of PCOS patients seems to be clearer and most preparations increase total cholesterol, high-density lipoprotein cholesterol and triglycerides. In summary, it is important to balance the potential benefits and risks of the COCs individually before prescribing them for PCOS women.

Traditional Persian Medicine and management of metabolic dysfunction in polycystic ovary syndrome

Polycystic ovary syndrome (PCOS) is a common endocrine disorder in women of reproductive age. Its cause is unknown and it remains the most enigmatic of reproductive disorders. The extant written documents of Traditional Persian Medicine (TPM) - with holistic approaches towards human health - contain remedies used for centuries. Before further experimental research on any of these treatments, it is appropriate to study current related scientific evidence on their possible pharmacological actions. This work aims to study PCOS and its treatments in TPM. To collect data from medieval medicinal texts, six of the most famous manuscripts of Persian medicine were studied. Medicinal treatments for a problem similar to PCOS were searched for in these books. The plants were listed and their authentications were confirmed in accordance with botanical books. PubMed and ScienceDirect databases were searched for related mechanisms of action or pharmacological activities of the medicinal plants reported. From numerous articles, the current work tried to cite the latest publications with regard to each reported plant and PCOS-related mechanisms of action. We studied herbal treatments recommended by ancient Persians to treat a condition called Habs-e-tams, which had the same symptoms of PCOS. It could be concluded that ancient physicians not only wanted to treat the irregular menstrual cycle-which is the most obvious symptom of PCOS-but also their treatment options were aimed at ameliorating the related underlying metabolic dysfunctions. The recommended herbs, which have the most scientific proof for their related actions, can be studied further in experimental analyses.

Hormonal contraception in women with polycystic ovary syndrome: choices, challenges, and noncontraceptive benefits

Polycystic ovary syndrome (PCOS) is an endocrine disorder among women of reproductive age characterized by chronic anovulation and polycystic ovary morphology and/or hyperandrogenism. Management of clinical manifestations of PCOS, such as menstrual irregularities and hyperandrogenism symptoms, includes lifestyle changes and combined hormonal contraceptives (CHCs). CHCs contain estrogen that exerts antiandrogenic properties by triggering the hepatic synthesis of sex hormone-binding globulin that reduces the free testosterone levels. Moreover, the progestogen present in CHCs and in progestogen-only contraceptives suppresses luteinizing hormone secretion. In addition, some types of progestogens directly antagonize the effects of androgens on their receptor and also reduce the activity of the 5α reductase enzyme. However, PCOS is related to clinical and metabolic comorbidities that may limit the prescription of CHCs. Clinicians should be aware of risk factors, such as age, smoking, obesity, diabetes, systemic arterial hypertension, dyslipidemia, and a personal or family history, of a venous thromboembolic event or thrombophilia. This article reports a narrative review of the available evidence of the safety of hormonal contraceptives in women with PCOS. Considerations are made for the possible impact of hormonal contraceptives on endocrine, metabolic, and cardiovascular health.

Comparison of Drospirenone- with Cyproterone Acetate-Containing Oral Contraceptives, Combined with Metformin and Lifestyle Modifications in Women with Polycystic Ovary Syndrome and Metabolic Disorders: A Prospective Randomized Control Trial

Background:

While combined oral contraceptives (COCs) are commonly used to treat polycystic ovary syndrome (PCOS), comparative data regarding metabolic effects of different progestogens on this patient population are missing. This study aimed to compare the different effects of drospirenone (DRP)-containing COCs with cyproterone acetate (CPA)-containing COCs, combined with metformin and lifestyle modifications in women with PCOS and metabolic disorders.

Methods:

Ninety-nine women with PCOS and a metabolic disorder between January 2011 and January 2013 were enrolled into this prospective randomized clinical trial. Participants were randomized into two groups such as DRP-containing COCs, and CPA-containing COCs. Participants took COCs cyclically for 6 months, combined with metformin administration (1.5 g/d) and lifestyle modifications (diet and exercise). Clinical measures and biochemical and hormone profiles were compared. Comparisons for continuous variables were evaluated with paired and unpaired Student's t-tests. The Wilcoxon signed rank test was used when the data were not normally distributed. Analysis of covariance was used to control for age, body mass index (BMI), and baseline data of each analyzed parameter when compared between the two groups.

Results:

A total of 68 patients have completed the study. The combination regimen of COCs, metformin, and lifestyle modifications in these patients resulted in a significant decrease in BMI, acne, and hirsutism scores when compared to baseline levels in both groups (P < 0.05). Blood pressure (BP) was significantly different in the CPA group when compared to baseline (75.14 ± 6.77 mmHg vs. 80.70 ± 5.60 mmHg, P < 0.01), and after 6 months of treatment, only the change in systolic BP was significantly different between the two groups (4.00 [–6.00, 13.00] mmHg vs. –3.50 [–13.00, 9.00] mmHg, P = 0.009). Fasting glucose, fasting insulin, and homeostasis model assessment-insulin resistance decreased significantly in the DRP group (5.40 ± 0.41 mmol/L vs. 5.21 ± 0.32 mmol/L, P = 0.041; 13.90 [10.50, 18.40] μU/ml vs. 10.75 [8.60, 13.50] μU/ml, P = 0.020; 3.74 [2.85, 4.23] vs. 2.55 [1.92, 3.40], P = 0.008) but did not differ between the two groups. While individual lipid profiles increased in both groups, no statistically significant difference was observed.

Conclusions:

DRP-containing COCs combined with metformin and lifestyle modifications could better control BP and correct carbohydrate metabolism in women with PCOS and metabolic disorders compared with CPA-containing COCs.

Noncontraceptive use of oral combined hormonal contraceptives in polycystic ovary syndrome-risks versus benefits

The use of steroid sex hormones for noncontraceptive benefits has been endorsed by several medical societies. In women with polycystic ovary syndrome (PCOS), hormonal contraceptives are first-line therapy for concurrent treatment of menstrual irregularity, acne, and hirsutism. The association of PCOS with obesity, diabetes, and dyslipidemia frequently brings up the debate regarding risks versus benefits of hormonal contraceptives in this population. In women with PCOS, the lack of large-scale studies evaluating the risks with varying doses of ethinyl estradiol, types of progestins, and presence of confounding factors such as obesity, smoking, and other cardiometabolic comorbidities is a significant limitation in these deliberations. Although it is important to assess the absolute risk for major morbidities including cardiovascular events, currently, there are a paucity of long-term data for these outcomes in PCOS. Most of the current studies do not suggest an increase in risk of prediabetes/diabetes, clinically significant dyslipidemia, inflammatory changes, or depressive/anxiety symptoms with oral contraceptive pill use. Screening of women with PCOS for cardiometabolic and psychiatric comorbidities is routinely recommended. This information should be used by health care providers to individualize the choice of hormonal contraceptive treatment, adequately counsel patients regarding risks and benefits, and formulate an appropriate follow-up plan.

Systems pharmacology to investigate the interaction of berberine and other drugs in treating polycystic ovary syndrome

Polycystic ovary syndrome (PCOS) is a common multifactorial endocrine disorder among women of childbearing age. PCOS has various and heterogeneous clinical features apart from its indefinite pathogenesis and mechanism. Clinical drugs for PCOS are multifarious because it only treats separate symptoms. Berberine is an isoquinoline plant alkaloid with numerous biological activities, and it was testified to improve some diseases related to PCOS in animal models and in humans. Systems pharmacology was utilized to predict the potential targets of berberine related to PCOS and the potential drug-drug interaction base on the disease network. In conclusion, berberine is a promising polypharmacological drug for treating PCOS, and for enhancing the efficacy of clinical drugs.

Hormonal contraceptives: pharmacology tailored to women's health

BACKGROUND

In recent years, several new oral contraceptives have become available. In some ways, they represent an evolution in terms of individualization and compliance on the part of women. The new formulations make it increasingly possible to prescribe a specific hormonal contraceptive on an individual basis.

METHODS

A systematic literature search of PubMed was performed using the following combination of terms: 'oral contraceptives', 'estroprogestins' and 'combined oral contraceptive'. Only English-language papers published between January 2000 and July 2014 were included in our analysis. The present review analyzes all aspects of the choice of oral contraceptives in the different phases of a woman's life in detail.

RESULTS

Regarding the estrogen component, lowering the dose of ethinylestradiol (EE) helped reduce associated side effects. Natural estradiol is now available and represents a valid alternative to EE. And regarding progestins, the dose has changed over time, as well as the endocrine and metabolic characteristics. These are the fruit of much research into improvement of old products (19-nor-progesterone-derived progestins) with androgenic effects and testing of new molecules with improved metabolic neutrality in terms of insulin sensitivity and lipid parameters. New progestins were a genuine turning point because they greatly reduced major side effects, such as water retention, and their anti-androgenic properties made them indicated for all forms of hyperandrogenism associated with acne and mild hirsutism. The associations of estradiol/dienogest and estradiol/nomegestrol acetate are the most suitable contraceptives for women with abundant menstrual bleeding and can increase the number of potential users of hormonal contraception.

CONCLUSION

Progress in the provision of new oral contraceptives has improved the risk/benefit ratio, by increasing benefits and reducing risks. The present challenge is to tailor contraceptives to individual needs in terms of efficacy and protection of reproductive health.

Polycystic Ovary Syndrome in Adolescents

Polycystic ovary syndrome (PCOS) is a familial heterogeneous disorder affecting 6% to 10% of reproductive-age women. The use of criteria developed for adult women is problematic for the adolescent girl because the clinical features associated with PCOS are normal pubertal events. The recent consensus statement on PCOS in adolescents stated that hyperandrogenism and oligomenorrhea need to persist for at least 2 years to consider the diagnosis of PCOS. Although insulin resistance, hyperinsulinism, and obesity are often associated with PCOS, these features are not considered valid diagnostic criteria. Recent genomewide association studies implicate genetic loci involved in the hypothalamic-pituitary-ovarian axis.

What does a diagnostic label of 'polycystic ovary syndrome' really mean in adolescence? A review of current practice recommendations

Polycystic ovary syndrome (PCOS) is the most common female endocrine disorder, with many women initially presenting during adolescence. Diagnosis during this period is particularly challenging, yet many emphasize the importance of an early diagnosis given the long-term metabolic and reproductive health consequences associated with the syndrome. The objective of this study was to review the current literature to determine whether the diagnostic label 'PCOS' is necessary to effectively manage adolescent girls presenting with features of the syndrome. A literature search was conducted (PubMed, Medline, Informit Health and the Cochrane Database of Systematic Reviews) identifying papers addressing the diagnosis and management of PCOS during adolescence. Articles were selected based on date of publication, relevance of material and the quality of evidence presented. A total of 427 papers were screened, with 40 of these selected from the initial search. A subsequent 154 were included from manual review of reference lists from key papers identified in the initial search. Current guidelines recommend treating the individual manifestations of PCOS. In doing so, there is good evidence identifying that this approach adequately targets the underlying metabolic and reproductive changes associated with the syndrome. This suggests that providing a diagnostic label of PCOS is not actually necessary to effectively manage adolescent girls with features of this syndrome.

Polycystic ovary syndrome: chemical pharmacotherapy

INTRODUCTION

Polycystic ovary syndrome (PCOS) is the most common reproductive endocrine disease among women of childbearing age. The clinical features are heterogeneous and vary in intensity. Hirsutism, menstrual disorders and infertility are the most frequent conditions observed; however, long-term complications (dyslipidemia, hypertension, cardiovascular disease, type 2 diabetes mellitus, endometrial cancer) are also often described. Each disorder may be managed by tailored strategies, employing sequential or combined pharmacological and/or non-pharmacological treatment.

AREAS COVERED

The authors review the drugs used for PCOS management and discuss new approaches. A systematic MEDLINE search regarding the randomized controlled trials, retrospective and observational studies about medical treatments of PCOS, the Cochrane library for reviews and also search for registered trials on ClinicalTrials.gov is performed.

EXPERT OPINION

A uniform treatment for PCOS patients does not exist. Clinicians should perform an accurate evaluation of patients' characteristics, identifying the phenotypic target and, subsequently, the best-tailored treatment to manage one or more clinical issues. Lifestyle intervention should always be the first recommended approach unless other issues indicate that drug or hormonal interventions are superior.

Promising clinical practices of metformin in women with PCOS and early-stage endometrial cancer

Young women with polycystic ovary syndrome (PCOS) have a high risk of developing endometrial cancer (EC). There is an urgent need for non-surgical prevention and treatment strategies for these patients who fail to respond to progesterone treatment and wish to preserve their fertility. Recently, we have reported that the combined treatment with metformin and progesterone-based oral contraceptives has successfully reversed the early-stage EC into normal endometria in addition to improvement of insulin resistance in women with PCOS. More importantly, one of these treated women has successfully delivered a healthy newborn baby. However, before such treatment can be recommended to the clinical practice, the molecular basis of metformin in the endometrium under physiological and pathological conditions must be elucidated.

The effect of drospirenone (3 mg) with ethinyl estradiol (30 mcg) containing pills on ovarian blood flows in women with polycystic ovary syndrome: a case controlled study

OBJECTIVE

To evaluate whether oral contraceptive pill (OCP) therapy has any effects on ovarian stromal blood flow by using pulsed and color Doppler at the end of 3 months follow-up period of OCP-users and non-users with or without polycystic ovary syndrome (PCOS).

STUDY DESIGN

200 patients were included in the study. The patients were designed into four groups as follows; Group 1: PCOS patients that received OCP containing 30 mcg ethinyl estradiol (EE) plus 3mg drospirenone for 3 months (DRP n=50); Group 2: PCOS patients that received no medication (n=50); Group 3: Healthy controls that received OCP (EE plus DRP) (n=50); Group 4: healthy controls that received no medication (n=50). Resistance index (RI) and pulsatility index (PI) of both ovarian arteries, hormonal, anthropometric and biochemical parameters were assessed before and after 3 months.

RESULTS

There was a significant increament in RI and PI of both ovarian arteries in healthy controls (Group 3) and in women with PCOS (Group 1) who received OCP (p<0.001). The increment rate in both Doppler parameters were significantly higher in women with PCOS (Group 1) than healthy controls (Group 3) (p<0.001). Whereas RI and PI values of both ovaries remained unchanged in all untreated women with or without PCOS (Groups 2 and 4).

CONCLUSION

OCP therapy reduced ovarian vascularization in both PCOS and healthy users after 3 months of therapy and this decrease is especially noticeable in women with PCOS.

Therapy in endocrine disease: treatment of hirsutism in the polycystic ovary syndrome

Hirsutism is a common medical complaint among women of reproductive age, and it affects the majority of women with the polycystic ovary syndrome (PCOS). Increased rate of androgen production and its availability in tissue represent the main pathophysiological mechanisms responsible for hirsutism. In addition, androgens may be generated de novo in the hair follicle; therefore, circulating androgen levels do not quantify the real exposure of the hair follicle to androgens, as a quota is locally generated. Hirsutism is a clinical sign and not a disease in itself; its presence does not therefore necessarily require treatment, particularly in mild-to-moderate forms, and when an affected woman does not worry about it. Physicians should decide whether hirsutism is to be treated or not by evaluating not only the severity of the phenomenon but also the subjective perception of the patient, which does not necessarily correspond to the true extent of hair growth. In any case, a physician should manage a woman with hirsutism only on the basis of a diagnosis of the underlying cause, and after a clear explanation of the efficacy of each therapeutic choice. Cosmetic procedures and pharmacological intervention are commonly used in the treatment of hirsutism and are discussed in this paper. Importantly, there are different phenotypes of women with hirsutism and PCOS that may require specific attention in the choice of treatment. In particular, when obesity is present, lifestyle intervention should be always considered, and if necessary combined with pharmacotherapy.

Combination of Diane-35 and Metformin to Treat Early Endometrial Carcinoma in PCOS Women with Insulin Resistance

Background: Young women with polycystic ovary syndrome (PCOS) have a high risk of developing endometrial carcinoma. There is a need for the development of new medical therapies that can reduce the need for surgical intervention so as to preserve the fertility of these patients. The aim of the study was to describe and discuss cases of PCOS and insulin resistance (IR) women with early endometrial carcinoma while being co-treated with Diane-35 and metformin.

Methods: Five PCOS-IR women who were scheduled for diagnosis and therapy for early endometrial carcinoma were recruited. The hospital records and endometrial pathology reports were reviewed. All patients were co-treated with Diane-35 and metformin for 6 months to reverse the endometrial carcinoma and preserve their fertility. Before, during, and after treatment, endometrial biopsies and blood samples were obtained and oral glucose tolerance tests were performed. Endometrial pathology was evaluated. Body weight (BW), body mass index (BMI), follicle-stimulating hormone (FSH), luteinizing hormone (LH), total testosterone (TT), sex hormone-binding globulin (SHBG), free androgen index (FAI), insulin area under curve (IAUC), and homeostasis model assessment of insulin resistance (HOMA-IR) were determined.

Results: Clinical stage 1a, low grade endometrial carcinoma was confirmed before treatment. After 6 months of co-treatment, all patients showed normal epithelia. No evidence of atypical hyperplasia or endometrial carcinoma was found. Co-treatment resulted in significant decreases in BW, BMI, TT, FAI, IAUC, and HOMA-IR in parallel with a significant increase in SHBG. There were no differences in the FSH and LH levels after co-treatment.

Conclusions: Combined treatment with Diane-35 and metformin has the potential to revert the endometrial carcinoma into normal endometrial cells in PCOS-IR women. The cellular and molecular mechanisms behind this effect merit further investigation.

Endometrial progesterone resistance and PCOS

Polycystic ovary syndrome (PCOS) is a state of altered steroid hormone production and activity. Chronic estrogen exposure or lack of progesterone due to ovarian dysfunction can result in endometrial hyperplasia and carcinoma. A key contributor to our understanding of progesterone as a critical regulator for normal uterine function has been the elucidation of progesterone receptor (PR) expression, regulation, and signaling pathways. Several human studies indicate that PR-mediated signaling pathways in the nucleus are associated with progesterone resistance in women with PCOS. The aim of this review is to provide an overview of endometrial progesterone resistance in women with PCOS; to present the PR structure, its different isoforms, and their expression in the endometrium; to illustrate the possible regulation of PR and PR-mediated signaling in progesterone resistance in women with PCOS; and to discuss current clinical treatments for atypical endometrial hyperplasia and endometrial carcinoma in women with PCOS and accompanying progesterone resistance.
