  • Title: Ultrasound directed follicle aspiration for oocyte collection using the perurethral technique.
    Author: Parsons J, Pampiglione JS, Sadler AP, Booker MW, Campbell S.
    Journal: Fertil Steril; 1990 Jan; 53(1):97-102. PubMed ID: 2403937.
    Abstract:
    Our experience in 242 consecutive ultrasound directed follicle aspirations using the perurethral technique is reported. The mean number of follicles punctured per patient was 9.6 (range 20 to 35), resulting in a mean oocyte yield of 6.1 (range 0 to 31) per patient. It was necessary to change to another ultrasound directed route in 20 patients, and we failed to retrieve oocytes in a further 6 patients. There were no serious complications. The fertilization and cleavage rates were 68% and 91%, respectively. Embryo transfer was performed in 178 cases, resulting in 39 clinical pregnancies (21.9%). Ultrasound directed follicle aspiration by the perurethral route is an efficient way of collecting oocytes and is acceptable to patients. There is no need for general anaesthesia, so this technique is well suited to in vitro fertilization programs based on outpatient procedures.
