A nurse, 27, primary sterility for 5 years, had normal menstruation, normal size of uterus anterior. HSG: Rt. tube was not visible, Lt. tube slightly enlarged at ampulla. Ovaries were over-stimulated by clomiphene, HMG and hCG.8 ova were taken through vaginal aspiration under B-mode ultrasound scanning. Direct introduction of ova and washed sperms simultaneously into the uterus on Sept. 19, 1991 resulted in successful single pregnancy up to 36(+1) weeks. A 2 250 g normal baby boy was delivered on May 15, 1992 spontaneously. The base and prospect of this manoeuver are discussed with a reference to Craft's procedure.
