The results of laparoscopic (lap) and transvaginal (TV) oocyte pickups (OPUs) performed concurrently for in vitro fertilization in 232 consecutive treatment cycles have been reviewed. The patients were compared for age, preoperative estradiol concentration, luteal-phase support, and number of follicles aspirated and were found to be similar but were not matched for cause of infertility. The lap OPU group had more oocytes recovered per follicle aspirated (P less than 0.001), but because of a lower fertilization rate (P less than 0.01), the number of embryos transferred was similar. Nevertheless, more (P less than 0.05) pregnancies occurred in the TV OPU group. Patients were subgrouped so that comparisons of patients with the same cause of infertility, tubal disease alone, were considered. This showed that the pregnancy rate was still higher in the TV OPU group (P less than 0.05). TV OPU was less painful and not associated with increased morbidity, and since the data suggest that TV OPU was at least as successful as lap OPU, it is recommended that all oocyte pickups in the future be performed transvaginally.
