Objective: Acne is not solely a cosmetic problem. The clinical importance of acne in the estimation of androgen excess disorders is controversial. Recently, the Amsterdam ESHRE/ASRM-sponsored third PCOS Consensus Workshop Group suggested that acne is not commonly associated with hyperandrogenemia and therefore should not be regarded as evidence of hyperandrogenemia. Our aim was to investigate whether acne is a sign of androgen excess disorder or not.Study Design: This is a cross sectional study that was performed in a university hospital involving 207 women, aged between 18 and 45 years, suffering mainly from acne. The women were assigned as polycystic ovary syndrome (PCOS), idiopathic hirsutism (IH), idiopathic hyperandrogenemia (IHA). Women with acne associated with any of the androgen excess disorders mentioned above were named as hyperandrogenemia associated acne (HAA). Women with acne but without hirsutism and hyperandrogenemia and having ovulatory cycles were named as "isolated acne". Serum luteinizing hormone, follicle stimulating hormone, estradiol, progesterone, 17-hydroxyprogesterone, dehydroepiandrosterone-sulfate (DHEAS), androstenedione, total testosterone and lipid levels were measured.Results: Acne score was similar between the women with isolated acne and HAA. The most common cause for acne was PCOS and only 28% of the women had isolated acne. 114 (55%) women had at least one raised serum androgen level.Conclusions: In this study, 72% of acneic women had clinical and/or biochemical hyperandrogenemia. In contrast to the suggestion of ESHRE/ASRM-sponsored third PCOS Consensus Workshop Group, our data indicate that the presence of androgen excess disorders should be evaluated in women presenting with acne.

Objective: Gonadotropin releasing hormone agonists (GnRHa) decrease the expression of growth factors involved in the development of human endometriotic tissue. As endometriosis has been found to be associated with a mild increase in prolactin (PRL) serum levels, we aimed to evaluate changes in PRL serum levels as well as other hormones relevant to endometriosis and infertility during long-term administration of GnRHas in women with endometriosis.Study Design: In this prospective pilot study we obtained blood samples on the first day of leuporeline administration and then subsequently after 4, 8 and 12 weeks in 22 patients.Results: Median PRL levels were unchanged after 4 weeks, but significantly decreased 8 and 12 weeks after the first leuporeline administration (p1=0.085, p2=0.020, p3=0.001). There was no significant decrease in serum anti-Mullerian hormone (AMH) levels over the whole period of down regulation with leuporeline (p1-3>0.05).Conclusion: Our data support the hypothesis that the decrease of PRL levels might contribute to the known effect of GnRH treatment in patients with endometriosis via suppression of VEGF expression in endometriotic lesions. Moreover this study lends support to the thesis that AMH remains stable under GnRHa therapy and therefore can be also used as a marker of ovarian function prior to IVF-stimulation during down regulation.
