5-oxoproline supplementation enhances maturation and developmental competence of low-quality porcine cumulus-oocyte complexes during in vitro maturation.
This study investigated whether 5-oxoproline, a key metabolic intermediate in the gamma-glutamyl cycle, improves the maturation and developmental competence of low-quality porcine cumulus-oocyte complexes (COCs) during in vitro maturation (IVM). High-quality grade A COCs were used as the positive control (PC), whereas...
