Transvaginal sector scan sonography for needle guided transvaginal follicle aspiration and other applications in gynecologic routine and research.

A transvaginal sector scanner probe has been developed for precise needle-guided transvaginal follicle aspiration under sonographic control. The first results of transvaginal needle-guided follicle aspiration are presented. A high recovery rate was obtained (86% /follicle). The pregnancy rate after in vitro fertilization and embryo replacement was remarkably high (21.3%/cycle). Because exceptionally high-quality images of the organs in the pelvis are obtained, there are numerous other potential applications for the trans-vaginal sector scanner.
