STUDY QUESTION Does the expression of LHCG receptor (LHCGR) protein and key enzymes in the androgen biosynthetic pathway differ in normal human versus polycystic ovarian tissue? SUMMARY ANSWER LHCGR and 17α-hydroxylase/17-20-lyase (CYP17A1) protein levels are increased in polycystic ovaries (PCOs). WHAT IS KNOWN ALREADY The predominant source of excess androgen secretion in women with polyc...

BACKGROUND Insulin resistance and hyperinsulinaemia are well-recognized characteristics of anovulatory women with polycystic ovary syndrome (PCOS) but, paradoxically, steroidogenesis by PCOS granulosa cells remains responsive to insulin. The hypothesis to be tested in this study is that insulin resistance in the ovary is confined to the metabolic effects of insulin (i.e. glucose uptake and meta...

This study was designed to investigate the effect of environmental factors on the appearance of polycystic ovaries (PCO) during the first two decades of life. Ninety-four female-female twins who underwent a transabdominal ultrasound at the Royal Hospital for Women were sent a questionnaire asking about their birth details, feeding history as a baby, childhood illnesses and vaccination as w...

OBJECTIVE Idiopathic hirsutism (IH) or polycystic ovary syndrome (PCOS) are the most common causes of hirsutism which affects 5-10% of all women. The aim of this study was to evaluate the efficacy of flutamide plus diane 35 in the treatment of idiopathic hirsutism and polycystic ovary syndrome. MATERIALS AND METHODS 26 polycystic ovary syndrome and 24 idiopathic hirsutism patients were evalua...

OBJECTIVES We aimed to investigate whether glucocorticoid receptor gene polymorphisms are associated with clinical and metabolic profiles in patients with polycystic ovary syndrome. Polycystic ovary syndrome is a complex endocrine disease that affects 5-8% of women and may be associated with metabolic syndrome, which is a risk factor for cardiovascular disease. Cortisol action and dysregulation...

Background: Meta-analysis was used to evaluate the efficacy and safety of aspirin combined with letrozole in treatment polycystic ovary syndrome (PCOS).

Objective: We examined the relationship between insulin resistance and vascular function in three insulin resistant states (type 2 diabetes mellitus, non-HIV lipodystrophic diabetes, and non-diabetic polycystic ovary syndrome (PCOS)) and in healthy controls. Research Design and Methods: The population included 12 women with type 2 diabetes, 6 with lipodystrophic diabetes, 10 with polycystic ova...

OBJECTIVES: Polycystic ovary syndrome is a heterogeneous endocrine disorder that affects reproductive-age women. The mechanisms underlying the endocrine heterogeneity and neuroendocrinology of polycystic ovary syndrome are still unclear. In this study, we investigated the expression of the kisspeptin system and gonadotropin-releasing hormone pulse regulators in the hypothalamus as well as facto...
