How to Choose an Ovarian Stimulation Plan for Surrogacy in Mexico?

For families planning to build their family through surrogacy in Mexico, embryo quality is often one of the key factors to consider throughout the process. Before embryos are created, however, the number and quality of eggs are closely related to the ovarian stimulation stage. Therefore, many people researching surrogacy in Mexico naturally ask an important question: how should the ovarian stimulation plan be chosen?

What Does Ovarian Stimulation Do?

During a natural menstrual cycle, usually only one follicle becomes dominant and releases an egg through ovulation. During an IVF cycle, ovarian stimulation uses medication to encourage multiple follicles to develop at the same time, creating an opportunity to retrieve more mature eggs in a single egg retrieval procedure.

After ovarian stimulation, the doctor schedules egg retrieval based on follicular development. The retrieved eggs can then be fertilized with sperm and continue through embryo culture.

Therefore, ovarian stimulation is an important stage between eggs and embryos, but it is not the only factor determining the final outcome.

Ovarian responses vary significantly among women. Age, AMH levels, antral follicle count, baseline hormone levels, and previous responses to ovarian stimulation can all affect how the ovaries respond to medication. Retrieved eggs need to be assessed for maturity, fertilized, and then cultured as embryos. The number that ultimately develops into blastocysts will decrease further.

Therefore, when developing an ovarian stimulation plan, it is important to consider both egg maturity and the potential for subsequent embryo development. The number of eggs retrieved in one cycle cannot be directly equated with the final number of embryos available for transfer.

Embryo Culture and IVF-PGT Are Also Important

After fertilization, embryos need to continue developing in the laboratory. Some embryos can successfully develop to the blastocyst stage, while others may stop developing during the early stages. IVF-PGT can be performed after embryos develop into blastocysts to conduct relevant genetic testing and analyze the chromosomal status of embryos, providing more information for subsequent embryo selection and transfer.

When the entire reproductive plan extends from eggs and sperm to embryo culture and subsequent transfer, each stage is connected. Understanding the logic behind ovarian stimulation in advance can also make the overall planning of surrogacy in Mexico clearer.
