Mild androgen phenotypes.
2006
Mild androgen phenotypes are found in 30-40% of patients referred to an endocrine clinic because of suspected hyperandrogenic syndrome. These disorders are characterized by clinical or biological signs of hyperandrogenism in women with normal ovulatory menstrual cycles. Three main mild androgen disorders may be distinguished: ovulatory polycystic ovarian syndrome (PCOS), idiopathic hyperandrogenism, and idiopathic hirsutism. Ovulatory PCOS includes ovulatory hyperandrogenic patients presenting with polycystic ovaries. Using ESHRE/ASRM criteria for diagnosis of PCOS, this disorder is now part of PCOS spectrum. While in vivo and in vitro studies have confirmed the similarities between the two…
Milder forms of atherogenic dyslipidemia in ovulatory versus anovulatory polycystic ovary syndrome phenotype
2017
BACKGROUND: Dyslipidemia is common in women with polycystic ovary syndrome (PCOS) but its prevalence in different PCOS phenotypes is still largely unknown. METHODS: We measured plasma lipids and lipoproteins in 35 anovulatory PCOS (age: 25 ± 6 years, BMI: 28 ± 6 kg/m2), 15 ovulatory PCOS (age: 30 ± 6 years, BMI: 25 ± 3 kg/m2) and 27 healthy women (controls) age- and BMI-matched with ovulatory PCOS. PCOS was diagnosed by the presence of clinical or biologic hyperandrogenism associated with chronic anovulation and/or polycystic ovaries at ultrasound. In women with normal menses chronic anovulation was indicated by low serum progesterone levels (<9.54 nmol/l) during midluteal phase (days 21…
Influence of sociocultural factors on the ovulatory status of polycystic ovary syndrome.
2009
OBJECTIVE: To evaluate the role of social and cultural differences inside the same ethnic group on the ovulatory status of women with polycystic ovary syndrome (PCOS). DESIGN: To correlate social and cultural status with the phenotypic expression (body weight and ovulation) and with androgen and insulin levels of PCOS. SETTING: University department of medicine. PATIENT(S): Two hundred and forty-four consecutive PCOS women. INTERVENTION(S): All studied patients completed a simple questionnaire to indicate their mean family income and their school education. MAIN OUTCOME MEASURE(S): Ovulation was assessed by measurement of serum progesterone on day 22 of a spontaneous or induced menstrual cy…
Does ovarian blood flow distinguish between ovulatory and anovulatory patients with polycystic ovary syndrome?
2003
The purpose of this study was to determine whether parameters of ovarian blood flow distinguish between women with polycystic ovary syndrome (PCOS) who ovulate and those who are anovulatory.This was a prospectively enrolled trial, carried out as a cross-sectional comparison of 12 ovulatory patients with PCOS and 20 matched subjects with classic PCOS and 10 healthy control subjects. Hormonal parameters and ovarian blood flow by color flow Doppler imaging were obtained in the early follicular phase.Characteristic elevations in luteinizing hormone (LH) and androgens were found in both groups with PCOS compared with control groups. Women with anovulatory PCOS had high insulin levels and lower Q…
Does metformin induce ovulation in normoandrogenic anovulatory women?
2004
Objective: This study was undertaken to evaluate the efficacy of metformin in women with anovulation who do not have evidence for hyperandrogenism and classic polycystic ovary syndrome. Study design: A randomized trial of metformin (1500 mg daily) and placebo in 24 anovulatory women was undertaken for 3 months. Assessments of changes in hormone levels and insulin sensitivity were carried out. Abnormal ormonal values were defined by levels exceeding the range in normal ovulatory controls. Results: Anovulatory women had normal androgen levels and luteinizing hormone but had higher serum insulin and lower insulin sensitivity compared with controls. Over 3 months, there were 16 ovulatory cycles…
Clinical and endocrine characteristics of the main polycystic ovary syndrome phenotypes
2009
Abstract OBJECTIVE: To evaluate the clinical and endocrine differences between main polycystic ovary syndrome (PCOS) phenotypes. DESIGN: To evaluate clinical and hormone parameters in a large group of consecutive women with PCOS diagnosed according Rotterdam criteria and divided according their phenotype. SETTING: University department of medicine. PATIENT(S): Three hundred eighty-two consecutive women with PCOS and 85 ovulatory controls. INTERVENTION(S): Evaluation of clinical and hormone parameters. MAIN OUTCOME MEASURE(S): Blood levels of gonadotropins, testosterone, sex-hormone-binding globulin, dehydroepiandrosterone sulfate, 17α-hydroxyprogesterone, progesterone, glucose, and insulin,…
Long-term consequences of polycystic ovary syndrome on cardiovascular risk
2009
Most available data suggest that the prevalence of cardiovascular diseases in women with polycystic ovary syndrome (PCOS) is smaller than expected based on risk calculations during fertile years; therefore, more studies are needed on long-term cardiovascular consequences. Evidence is accumulating that postmenopausal women with PCOS have an increased risk of cerebrovascular events and cardiovascular morbidity. These events are partially related to persisting hyperandrogenism but are mostly correlated with excessive body weight (mainly visceral obesity); this suggests that our best long-term strategy is to ensure that women with PCOS are informed about their high risk for metabolic and cardio…
PCOS: metabolic impact and long-term management.
2012
Polycystic ovary syndrome (PCOS) is the most frequent endocrinopathy in women, affecting up to 10% of those in reproductive age. Furthermore, PCOS presents a lifetime risk of type II diabetes, cardiovascular diseases and endometrial cancer. Women with PCOS have increased cardiovascular risk; however, the risk is not the same in all patients and it is necessary to assess an individual risk profile. There is a discrepancy between increased cardiovascular risk at young age and postmenopausal number of cardiovascular events, probablu depending on changes in androgen ovarian function after the forties. However, changes with age of metabolic profile in women with PCOS have not been studied yet an…
Influence of obesity on atherogenic dyslipidemia in women with polycystic ovary syndrome.
2013
Background Obesity is known to underlie, at least partially, dyslipidemia in polycystic ovary syndrome (PCOS), but it is unclear whether PCOS status per se increases the risk of alterations of lipoprotein subfractions, which differ in size and atherogenic potential. Our objective was to evaluate whether PCOS influences lipoprotein profile and LDL and HDL subfractions and to study the impact of obesity on these parameters. Materials and methods This was a case–control study conducted in an academic medical centre. The study population consisted of 54 women of fertile age with PCOS and 60 controls adjusted for age and BMI. Biochemical lipid profile and LDL and HDL lipoprotein subfractions (me…
A 20-year follow-up of young women with polycystic ovary syndrome.
2012
OBJECTIVE: To determine whether hormonal, metabolic, and anthropomorphic parameters change over 20 years in women with polycystic ovary syndrome (PCOS). METHODS: One hundred ninety-three women with PCOS, aged 20–25 years, were diagnosed according to Rotterdam criteria, divided into four phenotypes (A–D), and followed at 5-year intervals for 20 years. Androgens, gonadotropins, insulin, glucose, body mass index, waist circumference, and ovarian volume were measured. RESULTS: At diagnosis, 57% had classic features (phenotype A), 9% had classic features without ovarian findings (phenotype B), 26% had the ovulatory phenotype (C), and 7% were nonhyperandrogenic (D). After 10 years, androgens decr…
