title: In vitro fertilization: sonographic perspective.
abstract: The applications of sonography were evaluated in 220 patients undergoing 354 in vitro fertilization cycles. A baseline sonogram demonstrated adnexal abnormalities in 10.7% of cycles. Serial sonograms were beneficial in monitoring follicular development. Oocyte harvest was canceled in 18.4% of cycles owing to inadequate follicle growth progression, as demonstrated by ultrasound. An additional 9% of cycles were canceled owing to the development of a single lead follicle. Six percent of cycles were accompanied by a spontaneous rise in serum luteinizing hormone values, necessitating sonographic correlation to exclude ovulation.
