Summary

This completed Phase 3 trial compared two fertility drugs—follitropin delta (Rekovelle) and follitropin alfa (Gonal-F)—in 301 Chinese women undergoing IVF. The goal was to see which starting dose leads to the best number of eggs retrieved. Participants received daily injections for up to 20 days, with doses adjusted based on response.
