Transvaginal sonographically controlled ovarian puncture for oocyte retrieval for in vitro fertilization.
Two hundred twenty-two patients took part in a trial of follicle puncture via the transvaginal route under sonographic control for the purpose of in vitro fertilization (IVF). Induction protocols were mainly human menopausal gonadotropin (hMG) + human chorionic gonadotropin (hCG) and clomiphene + hMC + hCG. In 79.7% oocyte aspiration could be achieved without difficulty via the transvaginal route. An average number of 4.7 oocytes per attempt was obtained; 10.7% evolutive pregnancies were obtained. No major incident was noted. This technique offers several crucial advantages: it reduces surgical risk, reduces the length of the patient's stay in hospital as well as the overall cost of the procedure, and it also makes possible puncture in some cases hitherto regarded as excluded.
