Use of a vaginal transducer for oocyte retrieval in an IVF/ET program

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.
