Objective: To relate the levels of follicular steroid hormones with the ovarian stimulation cycle and its overall results. Method: It was included patients ≤ 38 years old with sterility of male, tubaric or unknown origin who underwent a long protocol with GnRH agonists and rFSH. Samples were obtained from the first and second follicular aspiration of each ovary. A chemiluminescent immunoassay of estradiol, progesterone, testosterone and DHEAS was performed. Results: Figures of follicular DHEAS decreased as the days of treatment with GnRH agonists increased (p=0.0003) and levels of follicular testosterone and DHEAS increased along with the days of treatment with rFSH (p=0.03, p=0.03). In regard to the outcomes of the overall cycle it was found a negative correlation between follicular testosterone levels and the number of punctured complexes (r= -0.360; p=0.002) and between follicular testosterone and the number of D quality embryos (r= -0.233; p=0.047). The number of mature oocytes was lower in patients with higher levels of follicular testosterone (p=0.008). Follicular progesterone was higher in good quality oocytes as compared to those of no remarkable quality (p=0.006) and very poor quality (p=0.04). Conclusions: High levels of follicular testosterone were correlated with a fewer number of punctured complexes, mature oocytes and D quality embryos. Good oocyte quality was associated with higher follicular progesterone levels.
