From June 1986 to February 1987 125 sonographically guided ovum pickups were performed vaginally. On comparison of the pelviscopic oocyte collection a 4% higher success rate was found using the ultrasound technique with regard to transfer and pregnancy rate. Despite two complications out of these 125 punctures, the sonographically guided aspiration technique has proved to possess several advantages in respect of its applicability and a lower incidence of stress factors for the patient.
