Abstract

PURPOSE:

The study aims to describe the newborn health parameters of the 50 first children conceived after autologous oocyte vitrification in France.

METHODS:

The 50 children born after autologous oocyte vitrification/warming cycle (VAO children) have been retrospectively compared with 364 children conceived by micromanipulation using freshly recovered non-vitrified oocytes (ICSI children). Children included in the study were born between 2011 and 2015. Maternal characteristics (age, body mass index, smoking habits), obstetric outcomes (diabetes, hypertension, placenta previa, parity, mode of delivery), and perinatal outcome (twinning, sex, birth weight, macrosomia, birth defects) were analyzed. The generalized estimating equation for correlated data was performed to evaluate perinatal outcomes and caesarean section.

RESULTS:

No statistically significant difference was found between VAO children and ICSI children, even after adjusting confounding factors (low birth weigh odds ratio (OR) 0.8, 95 % confident interval (CI) 0.3-2.2, adjusted (AOR) 0.5, 95 % CI 0.2-1.7; large for gestational age OR 1.5, 95 % CI 0.3-7.0, AOR 1.6, 95 % CI 0.3-7.5; birth defects OR 0.4, 95 % CI 0.1-3.2, AOR 0.5, 95 % CI 0.1-3.7; caesarean section OR 1.8, 95 % CI 0.9-3.4, AOR 1.8, 95 % CI 0.9-3.7).

CONCLUSIONS:

According to our results, newborn health parameters of children conceived in our center by micromanipulation using vitrified/warmed autologous oocytes seem not to be different from children born after micromanipulation on freshly recovered oocytes.
