title: The effect of progesterone supplementation around the time of oocyte recovery in patients superovulated for in vitro fertilization.
abstract: A randomized control trial involving 42 superovulated in vitro fertilization (IVF) patients was carried out to investigate the effects of providing supplementary progesterone (P) around the time of laparoscopy. P was given 12 to 15 hours and 1 hour before and 24 hours after laparoscopy in one group (group B); human chorionic gonadotropin was given 12 hours before laparoscopy in another group (group C); and the remainder received no treatment in addition to normal IVF procedures (group A). There was no difference in fertilization rate, the proportion of normally developing embryos, pregnancy rate, or birth rate between the treatment groups, We conclude that in the superovulation schedule used, P supplementation around the time of laparoscopy does not affect success rate of IVF.
