difficult diagnosis in endocrinology, gynecology, and reproductive medicine. to help solve this issue, the rotterdam consensus conference proposed to include the ultrasonographic follicle count as a new diagnostic criterion, in addition to hyperandrogenism and oligo-anovulation. unfortunately, its assessment does not offer sufficient reliability worldwide. objective: to explore the possible rol...

the androgen insensitivity syndrome is a heterogeneous disorder with a wide spectrum of phenotypic abnormalities, ranging from complete female to ambiguous forms that more closely resemble males. the primary abnormality is a defective androgen receptor protein due to a mutation of the androgen receptor gene. this prevents normal androgen action and thus leads to impaired virilization. a point m...

background: polycystic ovarian syndrome (pcos) is one of the most common endocrine disorders which cause anovulatory infertility and hyperandrogenism in young women. the common feature in pcos women is increased ovarian androgen secretion which can effect on the prevalence of miscarriage rate. objective: the aim of this study was to investigate the effect of pcos patient's serum on in vitro dev...

background: androgen receptors (ar) play an important role in proliferation of cancerous prostatic cells and prevention of apoptotic signaling. current drugs cannot inhibit the activity of these receptors very well. establishment of appropriate animal models is essential for discovery of new drugs of target therapy in hormone dependent prostate cancer. materials and methods: standard prostatic ...

The Wnt signaling pathway is aberrantly activated in many tumor types, including those of the prostate, in which beta-catenin accumulates in cell nuclei and acts as a transcriptional coregulator for the androgen receptor. Because activating mutations in the beta-catenin gene are rare in prostate cancer, we have looked for altered expression of other components of the Wnt signaling pathway in pr...

PCOS is one of the most common endocrine disorders among women between 12 and 45 years age, affecting 5-10% women. The patients were included in current study based on criteria Rotterdam diagnosis polycystic ovarian syndrome with at least two following three criteria: menstrual cycle disorder, chemical for high levels androgen, detection ovary using ultrasound (10 or more cysts 2-10 mm diameter...

Objective: The scientific community has recently directed its attention towards investigating the role of androgens in female sexuality. This narrative review aims to elucidate central and peripheral androgen-mediated mechanisms involved sexual health function. Additionally, current state androgen therapeutic options is discussed. Mechanism: We searched several literature databases, including E...

Background: It is well known that there is a close relationship between elevated androgen plasma levels and the ultrasound findings of stromal hypertrophy in polycystic ovary syndrome (PCOS). The objective of this study was to investigate the effects metformin on the hyperandrogenism and ovarian volume in PCOS. Methods: The study is an unrandomized clinical trial with before–after desig...

This study was carried out to determine the mechanisms associated with loss of androgen dependency and disease progression in prostate cancer. We investigated the role of the androgen receptor and its relationship to other signal transduction proteins. A hormone-refractory prostate cancer cell line [high-passage LNCaP (HP-LNCaP)] was established in vitro. Cells were treated with inhibitors of m...
