Introduction: Hirsutism affects 5–8% of the whole female population. In most patients, hirsutism is associated with hyperandrogenemia and the most common cause of androgen excess is polycystic ovary syndrome; however, the clinical presentation of non-classical congenital adrenal hyperplasia(NCAH) in females is often indistinguishable from other hyperandrogenic disorders because of common clinical signs with hirsutism and poly cystic ovary syndrome(PCOS).<p class="abst...

Objective: Hirsutism, affects between 5% and 10% of women during reproductive age. Hirsutism associated with normal ovulatory function and normal circulating androgen concentrations is defined as idiopathic hirsutism and little information is available regarding the molecular pathogenesis.Aim: Significance of polymorphisms of the genes involved in androgen/oestrogen biosynthesis (SRD5A2,CYP19) and their expressions inmodulating the susceptibility ...

Although the existence of the interaction between sex steroids and immune system is well known, the mechanisms of this interaction are still unclear. Recently a second form of GnRH (GnRH-II) has been described in human, which is significantly expressed in immune tissues suggesting a potential function. In a recent in-vitro study it has been demonstrated that GnRH-II decreases local expression of IL-2R in peripheral lymphocytes (1). However in-vivo interactions of...

Introduction: The pathogenesis of idiopathic hirsutism (IH) is not clear. On the other hand, human skin possesses all the enzymes necessary for androgen synthesis and catabolism indicating that it is an independent peripheral endocrine organ. Thus, in the present study we aimed to investigate the mRNA expression of aromatase enzyme and the other enzymes having functional roles in the steroidogenic pathway, in freshly obtained skin tissue from subumblical skin and the arm of wo...

Context: The prevalence of NCAH among Turkish women with hirsutism has not been established so far.Objective: To evaluate the prevalences of 21-hydroxylase (21-OHD) and 11-β hydroxylase deficiencies by ACTH stimulation test among hirsute women.Patients and methods: The study population consisted of 285 premenopousal women, aged 16–46 years (mean: 23.2±0.3). All were hirsute and hyperandrogenic. Androgen secreting tum...
