There are two different ways by which embryo freezing can take place- Vitrification and Slow Programmable Freezing (SPF).
The ability to freeze and preserve embryos is undoubtedly one of the greatest achievement in the field of Assisted Reproductive Technology. Below are the benefits you can get for future pregnancy/s with embryo freezing
Success rates of frozen embryo transfer is usually higher as compared to fresh IVF embryo transplant because of the age increase in the couple from the time of last egg retrieval. Success of both frozen and fresh embryo depends on the maternal age of the mother at the time of embryo transfer. Women below the age of 35 years of age have 60 percent higher chances of getting pregnant with a frozen embryo. However, the success rate of pregnancy with frozen embryo keeps decreasing with rising maternal age and also with the length of freezing.
