Evidence that insulin and androgens may participate in the regulation of serum leptin levels in women
1999
Abstract Objective: Although serum leptin is principally influenced by body mass, to understand the role of insulin and androgens in the regulation of serum leptin in normal weight women. Design: Prospective observational study. Setting: Academic practice in reproductive endocrinology. Patient(s): Twenty-one women with polycystic ovary syndrome (PCOS) of normal body weight, 8 apparently normal women with polycystic-appearing ovaries (PAO), and 21 normal women. Intervention(s): Fasting blood levels of luteinizing hormone, follicle-stimulating hormone, testosterone (T), unbound T, dehydroepiandrosterone sulfate (DHEAS), insulin, insulin growth factor–binding protein-1 (IGFBP-1), and leptin.

Androgen excess and cardiovascular risk.
2007
Cardiovascular diseases represent the major cause of death in most of developed countries and ultimately kill as many men as women. Both genders are exposed to the same risk factors but their rates of cardiovascular morbidity and mortality are very different until old age. This represents a crucial point; in fact, only at age 75 and over cardiovascular rates of women approximate those of men. It has been suggested that differences in hormonal status and mainly in androgen levels may explain such gender disparity. Consistently with this hypothesis, it has been shown that women with polycystic ovary syndrome (PCOS) have elevated cardiovascular risk despite their young age. However, the possib…
Correlates of increased lean muscle mass in women with polycystic ovary syndrome.
2009
ObjectiveMuscle mass plays an important role in determining cardiovascular and metabolic risks in polycystic ovary syndrome (PCOS). In addition, whether lean mass influences carotid intima-media thickness (IMT) in PCOS has not been assessed.DesignProspective investigation.MethodsNinety-five women with PCOS were age- and weight-matched to 90 ovulatory controls. All women had dual X-ray absorptiometry for lean, fat and bone mass, and bone mass density (BMD). Serum testosterone, sex hormone-binding globulin, insulin, and glucose and carotid IMT were determined. Free androgen index (FAI) and insulin resistance (by QUICKI) were calculated.ResultsIn PCOS, waist circumference and insulin were high…
New options in assisted reproduction technology: the Cryotop method of oocyte vitrification
2008
The Cryotop vitrification method has been shown to be a very useful tool for oocyte cryopreservation, giving excellent results regarding survival and clinical outcome. There are several clinical situations in which oocyte cryopreservation provides solutions that have not been available to date. This report describes three of these situations: (i) a low-responder patient who needed a single gene diagnosis due to the presence of a genetic disease; (ii) a patient undergoing endometrial bleeding on the day of oocyte retrieval who was also affected by a genetic disorder; and (iii) a patient who failed to become pregnant after the donation of vitrified oocytes and subsequently had the re-vitrifie…
Assessing cardiovascular risk in Mediterranean women with polycystic ovary syndrome
2010
Background: Although dyslipidemia is common in the polycystic ovary syndrome (PCOS), current diagnostic guidelines suggest to evaluate only plasma HDL-cholesterol and triglyceride concentrations, assuming that, in this disorder, cardiovascular risk is mainly due to the presence of the metabolic syndrome (MS). In the US, MS has been found in up to 50% of PCOS, but in other countries its prevalence is lower. Methods: We compared the prevalence of MS with that of increased LDL- and non-HDL-cholesterol levels in 350 Mediterranean PCOS women (244 anovulatory and 106 ovulatory), and 95 normo-weight and 90 body mass index (BMI)-matched controls. Results: The prevalence of MS was 7.1% in PCOS, high…
Day-3 embryo metabolomics in the spent culture media is altered in obese women undergoing in vitro fertilization
2015
Objective To determine whether the global metabolomic profile of the spent culture media (SCM) of day-3 embryos is different in obese and normoweight women undergoing in vitro fertilization (IVF). Design Prospective cohort analysis. Setting IVF clinic. Patient(s) Twenty-eight young, nonsmoking women with normoweight, nonsmoking male partners with mild/normal sperm factors undergoing a first IVF attempt for idiopathic infertility, tubal factor infertility, or failed ovulation induction: obese ovulatory women (n = 12); obese women with polycystic ovary syndrome (PCOS; n=4); normoweight ovulatory women (n = 12). Intervention(s) Fifty μl of SCM collected from two day-3 embryos of each cohort. M…
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…
