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.
