[Comparison of vaginosonographic, transabdominal sonographic and laparoscopic follicle puncture for the retrieval of oocytes within the scope of an in vitro fertilization program].

For follicular aspiration and oocyte retrieval for in-vitro-fertilization (IVF) laparoscopy, laparotomy and different ultrasound guided methods like transvesical and transvaginal puncture can be used. Sonographically guided follicular aspiration has become more important because this procedure is less invasive. In this study we compared the results of 28 laparoscopical, 35 transabdominal and 21 transvaginal follicle puncture after successful cycle stimulation. Performing transvaginal puncture 4.7, using laparoscopy 3.4 and performing transvesical puncture 2.0 oocytes per attempt were retrieved. The advantages of transvaginal follicle aspiration were a shorter operation time, a superficial anesthesia and compared to laparoscopy a less invasive and simple technique. Therefore this method is now commonly used for routine IVF procedures in our institution.
