Live births after oocyte in vitro maturation with a prematuration step in women with polycystic ovary syndrome.

ABSTRACT:

Purpose

Standard oocyte in vitro maturation (IVM) usually results in lower pregnancy rates than in vitro fertilization (IVF). IVM preceded by a prematuration step improves the acquisition of oocyte developmental competence and can enhance embryo quality (EQ). This study evaluated the effectiveness of a biphasic culture system incorporating prematuration and IVM steps (CAPA-IVM) versus standard IVM in women with polycystic ovarian morphology (PCOM).

Methods

Eighty women (age < 38 years, ≥ 25 follicles of 2-9 mm in both ovaries, no major uterine abnormalities) were randomized to undergo CAPA-IVM (n = 40) or standard IVM (n = 40). CAPA-IVM uses two steps: a 24-h prematuration step with C-type natriuretic peptide-supplemented medium, then 30 h of culture in IVM media supplemente
