OBJECTIVE:

To evaluate the relationship between antral follicular count and antimüllerian hormone with the number of oocytes retrieved and live birth rate.

MATERIALS AND METHODS:

Retrospective, observational, descriptive and comparative study carried out in patients attended at a tertiary level hospital. Study parameters: IVF-ICSI cycles performed between January 2017 and March 2021. The cycles, for study purposes, were divided into three groups: 1) antral follicular count, 2) antimüllerian hormone and 3) both parameters altered. To evaluate the relationship of the markers with the number of oocytes recovered and the live birth rate, an exploratory statistical analysis was performed. Sociodemographic and clinical characteristics were compared between the three groups using Kruskal-Wallis and 2 tests for continuous and categorical variables, respectively. A level of less than 0.50 was considered significant; STATA 12 statistical software was used.

RESULTS:

Among the three groups analyzed, 222 cycles were included: with antral follicular count, antimüllerian hormone or both altered. Fifty-four (24.3%) were found with a live birth. The number of antral follicles and live birth rate were significantly lower in patients with both markers altered. Patients with altered antimüllerian hormone concentrations had better prognosis (MR 2.3; 95%CI: 1.08-4.93, p < 0.03). FSH dose and number of embryos transferred were the variables that influenced the probability of having a live newborn.

CONCLUSIONS:

Antimüllerian hormone concentration less than 1.2 ng/mL is related to better ovarian response and higher live birth rate. This higher probability is influenced by the number of gonadotropins used and embryos transferred.
