Apply Biphasic IVM for POSEIDON Group 1

The goal of this clinical trial is to learn if biphasic In Vitro Maturation (IVM) works to help young women who produce very few oocytes after controlled ovarian stimulation. The study focuses on women under age 35 who have a good number of follicles in their ovaries but do not respond well to standard ovarian stimulation by Gonadotropin (known as POSEIDON Group 1a). The main questions it aims to answer are: How many mature oocytes can be obtain after biphasic -VM? Researchers will use biphasic-IVM system to see if it can bypass the problems these patients face with standard treatments, such as high costs and the risk of medical complications like Ovarian Hyperstimulation Syndrome (OHSS). Participants will: Have their immature eggs collected from the ovaries without the need for high-dose hormone injections. Have their eggs matured in a specialized laboratory using a two-step process (biphasic IVM) to improve egg quality. Follow up with researchers to check the number of embryos created and the safety of the procedure.
