In this article, we discuss the importance of considering fertility preservation, the maximum age for freezing eggs, what egg cryopreservation involves, its advantages, and how you can prepare for it with Ana García Sifre, a fertility specialist embryologist at Vida Fertility.

Age for feezing eggs | Why is Fertility Preservation Important?

Fertility is a critical aspect of many people’s lives, but it can be vulnerable to various factors, with age being one of the most critical. Women are born with a finite number of eggs, and both their quantity and quality naturally decline over time. This means that the ability to conceive gradually decreases with each passing year.

However, age isn’t the only factor to consider. Certain diseases, such as cancer, may require treatments that can harm fertility. Additionally, more women are choosing to delay motherhood to pursue higher education, careers, or personal goals.

This is where fertility preservation comes into play. It offers the possibility of preserving reproductive options, even when challenges arise. This approach provides flexibility and allows for informed decisions about when to start a family.

How Are Eggs Frozen in a Laboratory?

Egg cryopreservation, also known as oocyte cryopreservation, is the process by which a woman’s eggs are collected, frozen, and stored for future use.

The Step-by-Step Process of Egg Vitrification

  1. The process begins with hormone injections to stimulate egg production.
  2. Once the eggs mature, they are retrieved via ovarian or follicular puncture.
  3. Vitrification: These eggs are preserved at very low temperatures, effectively maintaining their current state until the woman decides to use them.

When ready to conceive, the eggs are thawed, fertilized in the laboratory, and the resulting embryos are implanted into the uterus.

Maximum age for Egg Freezing: When is the best time to Freeze Eggs?

Egg freezing should ideally be done at an age when a woman has a good quantity and quality of eggs, meaning that fertility preservation depends on having a healthy ovarian reserve.

It’s recommended to undergo this process preferably before the age of 36, although this age can vary depending on a woman’s ovarian reserve. To assess ovarian reserve, a blood test to measure the antimüllerian hormone (AMH) is necessary.

How long does a frozen egg last?

Once eggs are frozen, a woman can choose to postpone motherhood until the right time. The storage of eggs has no time limit, and they will maintain their quality even after several years of vitrification.

If a woman is unable to conceive naturally, she can use her preserved eggs, avoiding the need for more complex treatments due to declining egg quality.

Fertility Preservation in Spain

Fertility preservation in Spain is becoming increasingly relevant for those who wish to delay motherhood, face fertility issues due to medical treatments or health problems, or simply want to plan their reproductive future.

According to data from the National Institute of Statistics, this practice has experienced a significant increase in demand in Spain in recent years. This has led to greater availability of services, including egg freezing, and specialized centers in this field.
