Ultrasonic and endocrinologic investigation of ovarian follicle and free fluid in cul-de-sac for monitoring follicular development and ovulation.
The accuracy of ultrasound as a means of monitoring follicular development and ovulation detection was studied in 31 infertile women. The follicular diameter measured by ultrasound correlated well actual diameter found during laparotomy (r = 0.88), and estradiol-17 beta (E2) and progesterone in follicular fluid aspirated from large follicles (greater than or equal to 16 mm) indicated high levels. Furthermore, in 23 out of the 55 cycles, ultrasound examinations demonstrated free fluid in cul-de-sac at ovulation, and concentrations of E2 and progesterone (P) in peritoneal fluid by the puncture of cul-de-sac dramatically increased after ovulation. We suggested that ultrasound monitoring provided a reliable measure of follicular growth and prediction of ovulation, and a combined use of ultrasound and puncture of cul-de-sac could be developed into a new tool for the study of the mechanism of human ovulation.
