Reassessment of adrenal androgen secretion in women with polycystic ovary syndrome
1995
Objective To reevaluate the clinical significance of elevations of adrenal androgens in polycystic ovary syndrome (PCOS). Methods Thirty women with PCOS and ten ovulatory controls were evaluated. Serum dehydroepiandrosterone (DHEA) sulfate and 11β-hydroxyandrostenedione were measured before and after 3 and 6 months of GnRH agonist (GnRH-A) therapy. All controls and 15 women with PCOS received intravenous ACTH before and after GnRH-A therapy. Results Twenty-one (70%) of the women with PCOS had elevations of DHEA sulfate, and 16 (53%) had elevations in 11/3-hydroxyandrostenedione. Only two women with PCOS had normal values of both adrenal androgens. After GnRH-A therapy, only 11 subjects (37%…
The follicular hormonal profile in low-responder patients undergoing unstimulated cycles: is it hypoandrogenic?
2012
STUDY QUESTION What is the final hormonal milieu of pre-ovulatory follicles of low-responder (LR) patients undergoing unstimulated cycles? SUMMARY ANSWER Neither androgen secretion nor LH was impaired in pre-ovulatory follicles of LR women. WHAT IS KNOWN ALREADY Therapies currently used to improve ovarian response in LR women have an impact on the final hormonal follicular milieu, and these changes are believed to be partially responsible for determining the success rate in these women. Surprisingly, as far as we know, there is no report of the final hormonal profile of LR women undergoing unstimulated cycles or evidence that follicular androgen secretion in LR women is impaired. STUDY DESI…
PCOS Phenotypes: Impact on Fertility
2018
Polycystic ovary syndrome (PCOS) is characterised by an extreme heterogeneity and at least four main phenotypes may be distinguished. In referred population, anovulatory hyperandrogenic phenotype (classic PCOS or phenotypes A and B) is by far the most common phenotype and presents the most severe endocrine and metabolic alterations. Ovulatory PCOS and normoandrogenic phenotype represent a mild form of PCOS that is more common in general population and/or (normoandrogenic) in some particular ethnic group. During their life, because of changes in lifestyle or because of spontaneous changes in ovarian and adrenal androgen secretion that occur during late reproductive age, patients may move fro…
Polycystic ovary syndrome: metabolic consequences and long-term management.
2014
Young women with polycystic ovary syndrome (PCOS) present an increased risk for type II diabetes and cardiovascular diseases. The prevalence of altered glucose tolerance ranges between 20 and 35 % in patients while the prevalence of type II diabetes ranges between 2 and 8 % and seems related to body weight and ethnic group. Moving from the young fertile age to the 40s and the menopause the prevalence of type II diabetes continues to increase compared to the general female population and may reach 10-16 % of PCOS women. However, prevalence of altered glucose tolerance does not increase. Also cardiovascular risk is increased in a large part of young PCOS women but this risk tends to be normal…
Hirsutism: investigation and management.
2019
In all hirsute women, a careful diagnostic evaluation should be performed, and the findings will largely influence the therapeutic decisions and the follow-up of the patients. An assay of serum 17-OH progesterone is needed, while the measurement of total testosterone and sex hormone-binding globulin, with the calculation of free androgen index, are useful to assess androgen secretion. Other tests should be suggested only according to responses of specific clinical questions. Owing to their high cardiovascular and metabolic risk, patients with polycystic ovary syndrome should have an oral glucose-tolerance test and a complete lipid profile. No ideal treatment for hirsutism exists but, with c…
Ovarian and Adrenal Hyperandrogenism
2007
Because in normal women androgens are secreted in almost equal quantities by both adrenals and ovaries, for many years many studies have tried to distinguish the source of androgen excess. However, in the last 10-15 years, the diagnoses of ovarian or adrenal hyperandrogenism have almost disappeared. This is due to the lack of specificity of dynamic tests as well as to the emphasis given on clinical information and ovarian sonography for the diagnosis of hyperandrogenic syndromes. However, determination of the source of increased androgens may still be useful for improving the classification and the understanding of androgen excess disorders. The aim of this review is to examine the source o…
