Vitrification of eggs: a good idea to preserve your fertility

More and more women delay the moment of being mothers. Social, labor, economic circumstances … postpone a biological process that has an expiration date. But vitrification of eggs is an option for those women who do not want to give up anything, or who see their fertility in danger. Do you know what it is?

It is a fact. The ability of a woman to achieve a healthy pregnancy plummets from 36 years. That does not mean that there are many women who become mothers for the first, second or third time from that strip and even after the quarantine has been reached. But, of course, not with the ovarian quality that is enjoyed at 20 or 25 years.


But what is the alternative? Who can afford to be a mother at such an early age? How to ignore the voices of nature, when hardly a woman begins to live her adult life to giving life to a new being, with what that entails? Egg Vitrification is a process of preserving female germ cells at extremely low temperatures for an indeterminate period of time until the future mother in question decides to take the plunge.

And, attention, we are not talking about freezing properly. Vitrification of eggs is a somewhat more sophisticated process, which allows a number of advantages in conserving biological material. Are you curious?

The advantages over freezing

If we imagine the preservation of eggs, we are likely to come to the head with immense coolers filled with test tubes. But the truth is that, although the freezing continues to be used, vitrification is somewhat different, and it has a number of advantages over simple freezing. First, vitrification is performed in liquid nitrogen, thereby preventing ice crystals from forming that could damage the cells. Thus, a greater number of oocytes are ensured intact and ready to fertilize when their recovery is carried out.

It is of this material and not in water that the structures (straws) in which the oocytes are stored are immersed. At about -196 degrees Celsius, the “freezing” occurs super fast, in just a few seconds. In addition, the influence of cryoprotectants, which are injected into the cells before being submerged, ensures that they remain intact over time.

Thus, vitrification allows time to stop for your fertility, and you can pick up the eggs from when you were 25 or 30 years old, the age at which you submit to the process, to be a mother exactly when you decide. Of course, as long as your body is still healthy to face a pregnancy. At that time, the oocytes are “devitrified” to be used in an assisted reproduction treatment.

To whom is vitrification intended?

Any woman, who has funds for it, can undergo a process of vitrification of eggs to delay maternity. Although the truth is that, in its origins, egg vitrification was designed to preserve the fertility of women with cancer, since chemotherapy and radiation treatments carry a risk of 50% decrease in female fertility. Even vitrification is an excellent option for women who donate eggs, and who need their biological material to be retained until used by another woman or couple wanting access to paternity.

In contrast, vitrification of eggs has become an option for those healthy women who are at their best reproductive moment but who can not, or do not want, to become mothers yet.

Studies, access to working life, economic stability, couple, housing … There are endless reasons why a woman may not feel prepared to have a child … yet. But one day it will be, and when that time comes, it will not be willing to sacrifice its reproductive quality. A way to reconcile biology and society, thanks to science. And you do you think?
