BACKGROUND:

The association between ovarian reserve test and ovarian response is well established, however, its ability to predict clinical pregnancy and the live birth is limited.

OBJETIVE:

Evaluate the clinical usefulness of the antral follicle count (AFC) to predict clinical pregnancy and live newborn.

MATERIALS AND METHODS:

Retrospective cohort study was made. In fresh IVF cycles, performed at INPer between 2011-2016. Including patients diagnosed with infertility, who underwent in vitro fertilization with fresh embryo transfer. The study variables were age, antral follicle count, basal FSH concentration and number of oocytes captured. A binary logistic regression model was performed. Statistical Package for Social Sciences (SPSS) was used for the statistical analysis. The probability of error alpha <5% was considered significant.

RESULTS:

A total of 923 in vitro fertilization cycles were included. The antral follicle count has a prediction for clinical pregnancy (ABC 0.59) and live birth (ABC 0.57). The optimal cut-off value with the highest percentage of clinical pregnancy (9%) and live birth (10.4%) was presented with a CFA ≥ 8. A higher pregnancy rate is reported when there is a follicular count above ≥8 follicles.

CONCLUSIONS:

It is expected the highest number of clinical pregnancy and live birth when the antral follicle count is for ≥8 follicles.
