This clinical trial is focused on studying treatments for female infertility. The study will compare two different methods of preparing the body for a procedure called DUOSTIM, which involves stimulating the ovaries to produce multiple eggs. The first method uses a medication called Progevera, which contains the active ingredient medroxyprogesterone acetate. This medication is taken in the form of a tablet. The second method uses a medication called Ganirelix, which is given as an injection under the skin. Both medications are used to help control the body’s hormone levels during the treatment process.

The purpose of the study is to determine if there is a difference in the number of healthy embryos that can be obtained using these two different methods. Participants in the study will undergo a process called embryo accumulation, where multiple eggs are collected and fertilized to create embryos. These embryos are then tested to ensure they have the correct number of chromosomes, a process known as PGT-A (Preimplantation Genetic Testing for Aneuploidies). The study will compare the effectiveness of the two methods in producing embryos that are suitable for this testing.

Participants will be divided into two groups, with each group receiving one of the two treatments. The study will last for a period of time during which participants will receive the medication and undergo the necessary procedures. The goal is to see which method results in a higher number of healthy embryos. This information could help improve treatment options for women experiencing infertility.
