Eligible GV oocytes from each enrolled participant are allocated within participant in a 1:1 ratio to either conventional r-IVM or r-IVM with OSC co-culture. The primary outcome is the metaphase II (MII) maturation rate after 24 hours of culture. Secondary outcomes include fertilization rate, day 3 embryo formation, good-quality day 3 embryo rate, blastocyst formation, and good-quality blastocyst rate.
