To estimate the probability of live birth, adverse treatment outcome, and extremes of ovarian response at different antral follicle count (AFC) cutoff levels in a large prospective cohort of women undergoing IVF treatment.
University-based assisted conception unit.
A total of 1,012 consecutive subjects of all ages undergoing their first cycle of assisted reproductive techniques.
Transvaginal three-dimensional ultrasound assessment and venipuncture in the early follicular phase of the menstrual cycle.
Main Outcome Measure(s):
Live birth rate, poor ovarian response, and ovarian hyperstimulation syndrome (OHSS).
Analysis was performed in 1,012 subjects. Both age (r = 0.88) and AFC (r = 0.92) thresholds show significant linear relationship with the probability of live birth, but AFC demonstrates a stronger correlation. At AFC quartiles of 3–10, 11–15, 16–22, and ≥23, the mean live birth rates were 23%, 34%, 39%, and 44%, respectively. No live birth was observed in women with AFC
Although age and AFC are significantly correlated with live birth, AFC demonstrates a stronger correlation. Antral follicle count thresholds are useful to predict live birth rates and risks of poor ovarian response and OHSS during IVF treatment.
