In patients with polycystic ovary syndrome (PCOS), the proportion of optimal embryos-blastomere number and fragmentation rate-derived from in vitro-matured oocytes after the hCG priming protocol was higher (43.3%) than the proportion of optimal embryos derived from oocyte in vitro maturation with the FSH priming protocol (11.1%). The embryos derived from in vitro-matured oocytes after the hCG priming protocol also showed a lower incidence of multinucleated blastomeres. Pregnancies were recorded only in the hCG primed patients.
