OBJECTIVE The syndrome of polycystic ovaries (PCOS) is a known risk factor for type 2 diabetes. It is not known, however, whether the increase in diabetes risk is related to endocrine abnormalities associated with PCOS such as hyperandrogenemia, or whether it is a consequence of the anthropometric or metabolic alterations frequently observed in PCOS women.(More)
The syndrome of polycystic ovaries (PCOS) is associated with adiposity and metabolic changes predisposing to insulin resistance and diabetes mellitus. Because the recently discovered GH secretagogue, ghrelin, is intimately involved in the control of appetite and weight regulation, we studied ghrelin levels in a group of 26 otherwise healthy women with PCOS.(More)
Purpose: The premature LH surge in ART programs seems to be avoided by daily administration of the GnRH-antagonist Cetrorelix during the midcycle phase in controlled ovarian hyperstimulation with hMG. The dosage necessary for sufficient suppression of the pituitary gland is not yet defined. Methods: To elucidate this question three daily dosages (3, 1, 0.5(More)
OBJECTIVE The polycystic ovary syndrome (PCOS) is associated with obesity and insulin resistance predisposing to diabetes mellitus type 2 and atherosclerosis. Adiponectin is a recently discovered adipocytokine with insulin-sensitizing and putative antiatherosclerotic properties. The aim of the study was to elucidate determinants of circulating adiponectin(More)
Endometriosis is an oestrogen-dependent disease that is treatable by oestrogen withdrawal, a therapy that has been effectively provided by the use of a gonadotrophin-releasing hormone (GnRH) agonist. Complete oestrogen withdrawal results in unacceptable side-effects, in particular in accelerated bone density loss. This problem has been effectively overcome(More)
Direct intracytoplasmic sperm injection (ICSI) is a successful treatment of severe male subfertility. Conventional in vitrofertilization shows poor pregnancy rates especially in cases of severe teratozoospermia. The objective was to determine if severe morphological defects of spermatozoa in oligoasthenoteratozoospermia (OAT) have any impact on the(More)
OBJECTIVE To evaluate the risk of testicular damage from testicular biopsies that are carried out for testicular sperm extraction (TESE) in infertile men. DESIGN Prospective controlled clinical study. SETTING Academic hospital. PATIENT(S) Forty infertile males with azoospermia. Examination of the clinical, endocrine, biochemical, and sonographic data(More)
We describe the case of a couple whose infertility was caused by the absence of seminal emission following retroperitoneal surgery for testicular cancer. Ejaculate could be retrieved from the husband by rectal probe electroejaculation (RPE) but sperm quality was so poor that conventional in-vitro fertilization was impossible. With intracytoplasmic sperm(More)
Polycystic ovary syndrome (PCOS) is a risk factor of type 2 diabetes. Screening for impaired glucose metabolism (IGM) with an OGTT has been recommended, but this is relatively time-consuming and inconvenient. Thus, a strategy that could minimise the need for an OGTT would be beneficial. Consecutive PCOS patients (n=118) with fasting glucose <6.1 mmol/l were(More)
OBJECTIVE Polycystic ovary syndrome (PCOS) is a risk factor for type 2 diabetes mellitus and screening for abnormal glucose metabolism has been recommended by an oral glucose tolerance test (OGTT). This procedure is time-consuming and inconvenient, limiting its general use. Therefore, an easy method is wanted to separate PCOS women with normal from those(More)
