title: Use of a vaginal transducer for oocyte retrieval in an IVF/ET program.
abstract: Sonography has proved to be an important diagnostic and operative instrument in an in-vitro fertilization and embryo transfer (IVF/ET) program. In some IVF/ET programs the technique has even replaced laparoscopy for oocyte retrieval. To date, transvesical follicle aspiration has been the main technique for ultrasound-guided oocyte pick-up. However, this technique has some disadvantages. Therefore, we have developed a transvaginal ultrasound-guided puncturing technique. A new high-frequency vaginal sector transducer was utilized (Brüel & Kjaer). This new transducer, equipped with a needle guide, changed the oocyte retrieval into a simple, safe, and rapid procedure that can be performed under local anesthesia without any discomfort for the patient.
