Antral follicle count in the prediction of poor ovarian response and pregnancy after in vitro fertilization: A meta-analysis and comparison with basal follicle-stimulating hormone level

Transvaginal ultrasonography is an easy-to-perform and noninvasive method that provides essential predictive information on ovarian responsiveness. The predictive performance of AFC toward poor response is significantly better than that of basal FSH. Therefore, AFC might be considered the test of first choice in the assessment of ovarian reserve prior to IVF.
