follicular tracking
Serial ultrasound monitoring of ovarian follicle development during controlled ovarian stimulation cycles.
Full Definition
Follicular tracking involves repeated transvaginal ultrasound examinations to monitor the number, size, and growth rate of ovarian follicles during assisted reproductive treatment cycles. This monitoring allows clinicians to adjust medication dosages and determine the optimal timing for trigger injection and oocyte retrieval. The process typically begins on day 5-7 of stimulation and continues every 1-3 days until follicles reach appropriate maturity. Editors should note this term is specific to fertility treatment protocols and differs from routine gynecological monitoring.
Usage
Usage note: Always hyphenate when used as an adjective (follicular-tracking ultrasound) but not as a noun phrase.
