Ovarian Endocrine Status and ART 0utcomes in Women within PCOS Based on Different Testosterone Levels.

Background: It is estimated that in women at reproductive age, the risk of polycystic ovary syndrome (PCOS) is about 5-21%. In PCOS cases with ovulation dysfunction, assisted reproductive techniques (ART) are useful for infertility treatment. Objective: This study aimed to evaluate the ART outcome in infertile PCOS women based on different testosterone levels. Finally, the relationships between testosterone in different levels and reproductive parameters including endocrine status, the response of ovaries, and pregnancy outcomes were assessed. Methods: In this retrospective study, 352 infertile PCOS women were examined. The women were categorised into five groups according to their testosterone levels: A = T < 0.4, B = 0.4 < T > 0.6, C = 0.6 < T > 0.8, D = 0.8 < T > 1.0 and E = T > 1.0 ng/dL. All study cases were in similar hyper-stimulation protocol and finally, hormonal profile and ART outcomes were compared between testosterone levels. P value ≤ 0.05 was statistically significant. Results: In testosterone levels >1.0, the levels of anti-mullerian hormone (AMH) and luteinising hormone (LH) were higher than in other testosterone level groups. AMH (P = 0.05) and LH (P = 0.001) levels showed significant differences. No correlation was present between testosterone levels and ART outcomes, including stimulation duration, endometrial thickness, oocyte numbers, numbers of matured oocytes, number of obtained embryos, fertilisation rate, implantation rate clinical pregnancy and abortion rate. Conclusions: Serum testosterone levels did not show any correlation with pregnancy outcomes in ART cycles of PCOS. However, basal testosterone levels are a good predictor for ovarian reserve and ovarian response. Consequently, we suggest that some prospective studies must be designed to approve the role of testosterone in the prediction of the outcome of pregnancy in ART cycles.

Is there any association between vitamin D levels and polycystic ovary syndrome (PCOS) phenotypes?

ABSTRACT Objective The aim of this study was to assess the serum vitamin D level in a retrospective study in women with polycystic ovary syndrome (PCOS), according to the different phenotypes of the disease. Subjects and methods In this retrospective study, the records of 351 infertile women who were diagnosed with PCOS were examined, and 200 of them were enrolled in the study randomly in 4 PCOS phenotypes. Fifty normal ovulatory women with the history of male factor were selected as the control group. Parameters, including age, infertility duration, body mass index (BMI), hormone profile, as well as the serum vitamin D level were compared among the 4 phenotypes, with the P-value ≤ 0.05 considered statistically significant. Results The findings showed a higher serum vitamin D level in the control group than in PCOS patients, which was statistically significant (P < 0.001). In addition, there was no significant difference in the serum vitamin D level among the four phenotypes of PCOS. Conclusions No significant difference was found in the serum vitamin D level of the different phenotypes of PCOS. Further studies with larger sample sizes are recommended to be done to establish the role of the serum vitamin D level in PCOS patients.
