RESUMO
The aim of this retrospective analysis was to evaluate the association between serum levels of various hormones and in vitro fertilization (IVF) parameters in poor responder patients. Serum levels of anti-Müllerian hormone (AMH), dehydroepiandrosterone sulfate (DHEAS), androstenedione and testosterone were measured before the start of IVF treatment cycle. We found that serum AMH and DHEAS levels were positively correlated with the number of mature oocytes, fertilized oocytes and developed embryos, both in pregnant and in non-pregnant patients. In contrast, we found a positive correlation between serum androstenedione levels and IVF parameters in pregnant, but not in non-pregnant patients. In this latter group, androstenedione levels were positively associated with the number of mature oocytes and were negatively correlated with the number of fertilized oocytes. No correlation was observed with developed embryos. Finally, we reported a negative correlation between serum levels of testosterone and IVF parameters in pregnant women whereas no correlation was observed in non-pregnant patients. Our results suggest that serum AMH and DHEAS could be predictive for oocyte retrieval and embryo development. Moreover, the positive correlation between serum androstenedione levels and IVF parameters in pregnant patients, together with the lack of a consistent correlation in non-pregnant women seem to identify androstenedione as a more predictive marker for pregnancy outcome than testosterone. In addition, in our analysis testosterone shows a negative correlation with IVF parameters.
