[Evaluation of the cervical factor in ovulation induction].

Post coital sperm penetration tests performed in 66 women under study for infertility, the purpose was to evaluate the ovulation induction effect over mucus quality and over sperm penetration. They were divided in three groups: 1) 28 women with evidence of spontaneous ovulation (control group), 2) 26 patients in which ovulation was induced with comiphene citrate and 3) 12 patients in which ovulation was induced with menotropins. The results showed that CC had an adverse effect over cervical mucus (p < 0.001), while in patients treated with menotropins the cervical mucus quality was not modified. Sperm penetration in patients under CC had a tendency to lower values than those in women of the control group, but these were statistically lower than those in patients under menotropins (p < 0.05). These results show the adverse effect of CC and the benefit of menotropins over cervical mucus and sperm penetration.
