Abstract
Between December 1986 and November 1987, 588 transvaginal sonographically-guided oocyte retrievals, using a vaginal transducer, were performed for in vitro fertilization at the University of Bonn. All follicles were accessible. No complication occurred except one case of pelviperitonitis in a patient with preoperatively diagnosed sactosalpinx. Because this technique is safe, non-invasive, and performable without general anaesthesia, we also retrieved eggs in patients despite poor hormonal values and endogenous LH-surge. In all, clinical pregnancies were diagnosed in 85 patients. Pregnancy rates per embryo transfer, oocyte retrieval and stimulated cycle, respectively were 19.0%, 14.5% and 12.0%. The advantages of the transvaginal technique, using a vaginal transducer compared with the laparoscopically-guided as well as with other sonographically-guided techniques of oocyte retrieval, are obvious (possibly without general anaesthesia, in general all follicles are accessible, very low complication rates, low discomfort to patient, and less amount of time and staff). Therefore, this technique seems to be the method of first choice. A laparoscopically-guided oocyte retrieval is only indicated, when a laparoscopic screening of pelvic organs or a gamete intrafallopian transfer are to be performed simultaneously.
