[Evidence of luteotropic activity of chorionic gonadotropin in patients with controlled ovarian stimulation]

Fourty seven women with infertility with controlled ovarian hyperstimulation with menotropins, were studied to corroborate the evidence of the luteotropic activity after the administration of human chorionic gonadotropin (hCG). They were divided in two groups: Group 1; 23 patients with (hCG). Group 2; 24 patients without (hCG). Seric progesterone level was determined at the 21 day of the cycle in both groups, with a significant difference (P < 0.05). We report 7 pregnancies; 5 in Group 1, and 2 in Group 2.
