Transvaginal recovery of oocytes for in vitro fertilization using vaginal ultrasound.

Vaginal recovery of oocytes for in vitro fertilization (IVF) was performed in 75 patients using a vaginal puncture transducer. Follicles were aspirated and flushed four times using a controlled vacuum. Oocytes were collected in 74 patients and an average of 5.1 oocytes was collected per patient. An average of 8.8 follicles was aspirated per procedure, giving an oocyte recovery rate of 58% per follicle. Pregnancy was obtained in seven patients (9.3%). The only complication was bleeding from the vagina of an estimated 40 ml in one case.
