OBJECTIVE To evaluate whether some ultrasound parameters of ovarian morphology can discriminate between control women and patients with polycystic ovary syndrome (PCOS). DESIGN Retrospective data analysis. SETTING Volunteers women in an academic research environment. PATIENT(S) Eighty amenorrheic or oligomenorrheic women and 30 normal ovulatory(More)
BACKGROUND The clinical heterogeneity of polycystic ovary syndrome (PCOS) is mirrored by the unceasing debate on the most appropriate diagnostic criteria. METHODS AND RESULTS To highlight differences and inconsistencies between NIH and ESHRE/ASRM criteria, we applied them to 375 patients with oligo/amenorrhoea and signs of hyperandrogenism. Among them, we(More)
We investigated the impact of pregestationally elevated insulin plasma levels on glycemic control in pregnant women with polycystic ovary disease (PCOD). Twelve patients with PCOD who became pregnant within six months following evaluation of their metabolic status were the study subjects. Four were obese and six (two obese) had a hyperinsulinemic response(More)
BACKGROUND The introduction of transvaginal approach in ultrasound (US) has enabled the accurate evaluation of the structure of the ovary and stroma. Stroma represents an acknowledged US marker for polycystic ovary syndrome (PCOS). The proportion revealed between the stroma and the ovary surface in the median section (S/A ratio) had been indicated as a(More)
Recent data indicate that an altered opioid tone could be involved in the LH hypersecretion and metabolic alterations seen in polycystic ovary syndrome (PCOS). The aim of the present study was to investigate the presence of a common mechanism of action of opioids on altered insulin and gonadotropin release in patients suffering from PCOS. Twenty-eight women(More)
Fifty-four hyperandrogenized women were studied to evaluate the importance of the adrenal or ovarian contribution to androgen secretion. Forty-six had the polycystic ovarian (PCOD) syndrome. Eight normal women represented a control group. The endocrine study was performed during the follicular phase. The plasma samples were collected at 7.00 am (A1) and at(More)
Pituitary adenylate cyclase-activating polypeptide (PACAP) is a novel bioactive peptide isolated from ovine hypothalamus. Recently, its presence and action have been demonstrated also in peripheral tissues such as testis and ovary. On the basis of sequence similarity, PACAP is included in the vasoactive intestinal peptide (VIP)/glucagon/secretin/growth(More)
OBJECTIVE To evaluate the effect of N-acetyl-cysteine (NAC) on insulin secretion and peripheral insulin resistance in subjects with polycystic ovary syndrome (PCOS). DESIGN Prospective data analysis. SETTING Volunteer women in an academic research environment. PATIENT(S) Six lean and 31 obese subjects, aged 19-33 years. INTERVENTION(S) Patients were(More)
Nineteen women with polycystic ovarian disease (PCO; 9 obese) and 15 normal ovulatory women (7 obese) were studied at their follicular phase. All patients had an oral glucose tolerance test (OGTT) before and after treatment with gonadotropin-releasing hormone (GnRH) agonist (Buserelin 400 micrograms/die s.c. for 8 weeks) to investigate the relationship(More)
OBJECTIVE To compare the use of GnRH agonist (GnRH-a) versus hCG in triggering the follicular rupture in patients with polycystic ovarian disease (PCOD) in whom ovulation was induced by gonadotropins. DESIGN Polycystic ovarian disease gonadotropin hyperstimulated cycles outcome was investigated in a prospective study. PATIENTS AND INTERVENTIONS(More)
