Introduction: Within the high prevalence of male infertility there is the rare 45,X/46,XY mosaicism, associated or not with hypogonadism. The phenotypes of this genetical disorder present with a wide variability ranging from Turner stigmata to apparent normal male.Case report: Two men who presented with azoospermia in the context of couple infertility were subsequently found to be affected by 45,X/46,XY mosaicism. Physical examination revealed a complete...

Aim: This study was aimed to estimate the nutritional status and the prevalence of weight excess in a wide unselected population of adolescent and young students from Emilia Romagna.Material and methods: Three thousand and ninety-one high school students, aged 15–19 years were consecutively contacted. One thousand eight hundred sixty out of 3091 (60.2%) accepted to participate in an epidemiologic study, whose procedures included anthropometric measu...

In a previous study, we demonstrated that the concept of functional ovarian hyperandrogenism (FOH), as documented by the exaggerated 17OHP response to buserelin (GnRH-analogue) does not represent a specific feature of all women with PCOS, being present in less than half of PCOS and is a condition characterized by more severe hyperandrogenemia, glucose-stimulated B-cell insulin secretion and worse insulin resistance. INSL3 is produced in the Leydig cells and at reduced levels i...

Obesity is strictly connected with Polycystic Ovary Syndrome (PCOS). However, we still do not know whether a form of PCOS secondary to obesity exists or whether obesity exacerbates manifestations of the syndrome. To answer this question we contacted seventy obese patients with PCOS that attended our Endocrinology Unit in the last 3 years and that lose weight after at least 6 months of dietary treatment. Sixty-five out of 70 patients agreed to take part to the study and gave th...

Among the uncertainties surrounding the etiology of polycystic ovary syndrome (PCOS) the role of increased peripheral cortisol metabolism has become interesting, particularly in relationship to the pathogenesis of adrenal hyperandrogenism. The patways of cortisol metabolism include irreversible inactivation of cortisol by 5α- and 5β-reductase. To evaluate the association of 5α- and 5β-reductase activity with adrenal hyperandrogenism in PCOS, we recruited 90...

Aim: The purpose of the study was to evaluate the prevalence of the metabolic syndrome (MS) in a cohort of young Mediterranean women with PCOS in reproductive age and to evaluate the association of the MS with clinical and biochemical parameters.Setting: Among 200 PCOS (17-31 years) criteria of MS in accordance with the “NCEP-ATPIII” were used to construct 3 groups: no one criteria, 1 or 2 criteria and 3 or more criteria (affected by MS). All p...

Insulin-like factor 3 (INSL3), a member of the relaxin-insulin family, is produced in the Leydig cells and at reduced levels in ovarian thecal cells. As ovaries from most of PCOS are characterized by an hyperplasia of the theca interna, we hypothesized that INSL3 could be overproduced in PCOS women and therefore that circulating levels of this hormone could became a new marker for the syndrome. Forty lean and obese women with PCOS and 20 controls comparable for age and weight ...

Objective: This study was aimed to evaluate the prevalence of non classical congenital adrenal hyperplasia due to 21-hydroxylase deficiency (21-NCAH) in hyperandrogenic women in the reproductive age attending our Endocrinology Unit and to identify specific phenotypic traits among clinical, biochemical and hormonal features.Setting: Outpatient Unit of Endocrinology, S. Orsola-Malpighi University Hospital of Bologna, Italy.Patients a...

Background and Objective: Severe metabolic complications generally manifest at an early age in Berardinelli – Seip congenital lipodystrophy (BSCL) and their management is especially challenging, often requiring prompt pharmacological treatment with insulin-sensitizers, lipid lowering drugs, insulin and eventually metreleptin. Nutritional intervention with low lipid personalized diets is considered by experts a fundamental tool in handling the disease when associated with ...

Background: Excess testosterone in PCOS is accompanied by increased levels of other ovarian and adrenal androgens and precursors. Recently, 11-oxygenated adrenal androgens have been postulated as major components of the circulating androgen pool in PCOS. Obesity is strictly connected with androgen excess and with the derangement of hormone circadian rhythmicity. To date, it has not been clarified whether hyperandrogenism in PCOS, either complicated by obesity or not, is accomp...
