... Abstract Polycystic ovary syndrome (PCOS) is a common metabolic and reproductive disorder in women. An increased cardiovascular risk has to be anticipated in PCOS as it is a metabolically unstable condition. Among cardiovascular risk factors, dyslipidemia is certainly the most persistent...

... Abstract In utero androgen excess reliably induces polycystic ovary syndrome (PCOS)-like reproductive and metabolic traits in female monkeys, sheep, rats, and mice. In humans, however, substantial technical and ethical constraints on fetal sampling have curtailed safe, pathogenic exploration...

... Abstract Most research efforts addressing the pathophysiology of polycystic ovary syndrome (PCOS) applied targeted approaches focusing on specific genes and/or proteins that were selected on the basis of previous knowledge about their putative roles in metabolic and signalling pathways...

... Abstract Both prevalence and incidence of the metabolic syndrome is very high in women with polycystic ovary syndrome (PCOS). Obesity and visceral fat enlargement play a dominant role in determining the final phenotype of PCOS. Androgen excess and insulin resistance may be responsible...

... Abstract Polycystic ovary syndrome (PCOS) is an oligogenic condition, with a heritability of ∼70%. PCOS is also associated with obesity, which itself is heavily influenced by genetic variants. PCOS is inherently difficult to study genetically, and most of the current literature (>70 studies...

... Abstract The polycystic ovary syndrome (PCOS), the most common disorder characterized by hyperandrogenism and ovarian dysfunction, is often associated with metabolic alterations, chiefly insulin resistance and obesity. Based on available scientific evidence, PCOS should be regarded...

... Abstract Amongst the commonest endocrine symptoms encountered in premenopausal women are those related to excessive androgen secretion or action, along with menstrual irregularity. The vast majority of women presenting with such symptoms will be found to have the polycystic ovary syndrome (PCOS...

... Abstract Polycystic ovary syndrome (PCOS) constitutes a continuum spectrum of symptoms starting from the early prepubertal years and continuing after menopause. The phenotypic expression varies through time, depending on several internal (e.g. ovarian/adrenal steroidogenesis, insulin resistance...

... Abstract In addition to its effects on reproductive health, it is now well recognized that polycystic ovary syndrome (PCOS) is a metabolic disorder, characterized by decreased insulin sensitivity which leads to an excess lifetime risk of type 2 diabetes and cardiovascular disease. PCOS patients...

... Abstract The cardinal features of polycystic ovary syndrome (PCOS) are hyperandrogenism and oligoanovulation. The increase in ovarian androgen production is a fundamental characteristic of PCOS and, although enigmatic, it is at the heart of one of the major issues about the pathophysiology...

... and subfertility. The resemblances between NCAH and polycystic ovary syndrome (PCOS) are manifest, and a relation between the two has been sought by many authors trying to identify subtle alterations in the CYP21 gene transcription end-products as the cause or a contributing cause of PCOS. On the other hand...

... Abstract When the symptoms of hyperandrogenism are mild in an adolescent girl, it is difficult to establish whether they are related to the physiological androgenization of puberty or to an incipient disease. The most frequent etiology is the polycystic ovary syndrome (PCOS). Its diagnosis...

... to being responsible for infertility. Undoubtedly, the polycystic ovary syndrome (PCOS) is the most common androgen excess disorder worldwide, and although this disorder is not the main focus of this book, some particular aspects are still discussed. One relevant part of this book focuses...

... Abstract Management of patients with polycystic ovary syndrome (PCOS) who wish to become pregnant should include exclusion of other diseases in the woman and additional fertility disorders in the couple. Before the initiation of any pharmacological intervention, the importance of lifestyle...

... Abstract Polycystic ovary syndrome (PCOS) is the commonest endocrine condition encountered in young women and has many reproductive, metabolic and psychological features that lead to patients consulting medical practitioners and the health service. Overweight and obesity are common among many...

... Abstract From the conceptual point of view, there are several reasons to expect that improvement of insulin sensitivity may produce several benefits in the treatment of a complex disorder like polycystic ovary syndrome (PCOS), including a decrease in insulin and androgen levels, improvement...

... Abstract Although polycystic ovary syndrome (PCOS) is the most common androgen excess disorder, screening for Cushing’s Syndrome (CS) should be considered in women with PCOS phenotype, particularly if they are also affected by other disturbances that increase their pretest probability (e.g...

... excess may also suggest the potential development of the polycystic ovary syndrome (PCOS). A new hypothesis, based on long-term lifestyle intervention programs or bariatric surgery, supports the concept that a “PCOS secondary to obesity” may exist, as confirmed by the complete resolution of all features...
