Updates on Egg Freezing

With so many life projects and goals to reach, many women decide to postpone maternity as much as they can. Some might not even be sure if maternity is in their plans for the future, but don’t rule it out. Others might need to undergo medical treatment that can affect their future fertility. Unfortunately, female fertility starts a rapid natural decline after age 40, and they may have trouble conceiving. For all these women looking to delay maternity, egg freezing could be their best option.

NYU Langone Fertility Center conducted a study over 15 years where they observed success rates of using women’s own frozen eggs. The study had 543 participants with an average age of 38, who had eggs removed and frozen. The patients underwent in total 800 egg freezing cycles, 605 egg thaws (frozen egg recovery process), and 436 embryo transfers between 2005 and 2020.

The results showed that around 70% of women who froze their eggs before age 38 later had a baby, and 39% of the women who were between 27 and 44 years old when they had their eggs frozen had at least one child from those eggs. Those who thawed 20 mature eggs, regardless of age range, had a 58% live birth rate (a considerable figure for women past their reproductive prime). The study also showed that women who froze their eggs past the optimal age to undergo the process (14 patients aged 41 and 42) could have children from their frozen eggs successfully. IVF and embryo transfers did not seem to be affected by how long the eggs had been frozen; actually, they had higher pregnancy success rates than using fresh embryos with assisted reproductive technology.
