[Initial experiences with transvaginal vagino-sonographically controlled follicle aspiration in an in vitro fertilization program].

From March to May 1987 41 sonographically guided follicular punctures have been performed vaginally. Altogether 208 follicles were aspirated and 149 oocytes (71.7%) could be found. No complications like of bleeding or pelvic inflammatory disease have been observed after puncture. The sonographically guided aspiration technique has proved to possess several advantages in respect of its applicability.
