For advanced-age intended parents choosing Mexico surrogacy to fulfill their wish for a family, a core question is: "How many eggs do I need to retrieve to finally hold a healthy baby?" COSTAIVF experts emphasize that in advanced-age parenthood, the key to success is no longer the absolute number of eggs retrieved, but the quality of the embryos and the reserve of healthy blastocysts. Understanding this "quantity-to-quality" conversion process can help you plan your IVF and Mexico surrogacy journey more scientifically.
The Challenge of Advanced Age: Converting from Quantity to Quality
As a woman's age increases, the rate of chromosomal abnormalities in her eggs rises significantly. This means that even if a relatively large number of eggs are obtained through ovarian stimulation, the proportion of healthy blastocysts that can pass IVF-PGT (Third-Generation IVF Genetic Screening) will drop substantially. This is a medical reality that must be addressed.
Core Difference: A younger woman might achieve a sufficient number of healthy embryos with just one retrieval cycle. In contrast, an advanced-age woman, due to the high attrition rate, may need to undergo multiple retrieval cycles to accumulate healthy embryos.
Key Goal: Our objective is not to pursue the peak number of retrieved eggs, but to obtain high-quality eggs that can develop into healthy blastocysts through an optimized stimulation protocol.
Healthy Blastocyst Reserve: The Cornerstone of Surrogacy Success
The biggest advantage of successful surrogacy lies in the optimization of the uterine environment, but the prerequisite is that the embryo quality must meet the standard.
Blastocyst Quantity Needed: To ensure the success rate of a single transfer in Mexico surrogacy, it is generally recommended to reserve 2–3 healthy blastocysts screened through IVF-PGT. This is based on the success rate of a single transfer and consideration for future family planning.
Precise Assessment: POWER FERTILITY CLINIC experts will predict your egg retrieval potential based on your AMH (Anti-Müllerian Hormone) value and Antral Follicle Count (AFC). If the assessment indicates insufficient retrieval in a single cycle, a multi-cycle strategy to accumulate enough eggs will be recommended.
IVF-PGT Screening Assurance: Before transferring the blastocysts to the surrogate mother, IVF-PGT screening is an indispensable step. It effectively avoids the risk of chromosomal abnormalities and miscarriage caused by advanced-age eggs, making it the core technology for guaranteeing the success rate of Mexico surrogacy.
Ultimately, when you have 2–3 healthy blastocysts screened through IVF-PGT, the success rate of the transfer to the surrogate mother will be greatly ensured, making your Mexico Surrogacy journey more manageable and reassuring.
