Amino acid turnover by human oocytes is influenced by gamete developmental competence, patient characteristics and gonadotrophin treatment.

Amino acid turnover by human oocytes is influenced by gamete developmental competence, patient characteristics and gonadotrophin treatment.
OBJECTIVE
Can amino acid profiling differentiate between human oocytes with differing competence to mature to metaphase II (MII) in vitro?
CONCLUSIONS
Oocytes which remained arrested on the germinal vesicle (GV) stage after 24 h of in vitro maturation (IVM) displayed
