Fertility Timeline: Storage Limits for Egg, Sperm, and Embryo Freezing in Mexico Surrogacy

For intended parents planning to use In Vitro Fertilization (IVF) technology combined with Mexico surrogacy, fertility preservation is a crucial step. Whether choosing egg freezing, sperm freezing, or embryo freezing, understanding the storage limits of these reproductive cells and tissues is key to formulating a long-term parenting plan. The vitrification cryopreservation technique adopted by professional fertility centers allows these valuable reproductive resources to be preserved long-term and safely at extremely low temperatures, providing ample time assurance for future Mexico surrogacy.

 The Long-Term Preservation Capacity of Reproductive Cells and Embryos

Egg freezing, sperm freezing, and embryo freezing are all achieved through ultra-low temperature storage in liquid nitrogen at -196°C. At this temperature, cellular metabolism is almost completely halted, theoretically allowing for indefinite preservation.

1.  Sperm Freezing Storage Limit

     Mature Technology: Sperm freezing is the earliest cryopreservation technique applied clinically, and the technology is relatively mature.

     Storage Duration: Scientific research and clinical practice indicate that sperm can be effectively preserved in liquid nitrogen for the long term. Successful cases have proven that sperm frozen for over 30 years still possess motility and fertilization capacity. For men, sperm freezing is the most direct and most effective way to preserve fertility.

2.  Egg and Embryo Freezing Storage Limit

     Technological Advancement: Egg freezing and embryo freezing (blastocysts) primarily rely on the vitrification cryopreservation technique, which prevents the formation of intracellular ice crystals, significantly increasing the survival rate upon thawing.

     Eggs and Embryos: Whether it is an egg or an embryo, once it reaches -196°C in liquid nitrogen, cellular activity is paused. This means its quality and viability do not diminish with extended storage time. Although legal or ethical requirements may impose time limits (often 10 years or longer), from a biological perspective, they can be preserved indefinitely. There are already successful cases of conception using eggs and embryos frozen for over 10 years.

The maturation of egg, sperm, and embryo freezing technologies empowers people with the ability to proactively manage their timing for parenthood.
