Technical and clinical aspects of ultrasound guided oocyte recovery.

In our experience, as well as that of many other IVF groups, transvaginal, ultrasound-guided follicle aspiration is less invasive and comparable to, or better than laparoscopy with regard to the efficiency of oocyte recovery and safety. For these reasons, we believe that ultrasound-guided follicle aspiration will gradually become the method of choice if the only purpose is to retrieve oocytes.
