Vitrification of gametes

Freezing eggs before a woman reaches 35 years of age

Preserving fertility consists in choosing the best moment to become a mother without the pressure of the biological clock. In addition to the different social reasons that may cause us to postpone motherhood, egg vitrification is advisable before undergoing aggressive medical treatment, where medication could affect the quality of the eggs or ovarian function.

A woman’s fertility peaks between the ages of 20 and 25, and this is when it is most likely that she will become pregnant naturally and healthily. Between 25 and 30 years of age, fertility begins to decline slowly and progressively, but after 35 years of age, a woman’s reproductive capacity decreases significantly. In addition, the number of eggs (ovarian reserve) decreases and those left are of poorer quality. After 38 years of age, the ovarian reserve generally decreases and the egg could contain alterations in its cellular structure, causing chromosomal alterations.  

For this reason, in Equipo Juana Crespo we insist that women who are sure that they wants to be mothers but do not know when the perfect moment will be should freeze her eggs before reaching 35, to allow us to obtain good-quality eggs (which is the most important) and a good quantity of them (greater opportunity).

The technique that we use to freeze is vitrification (eggs and embryos) or freezing (sperm) with nitrogen. Unlike other clinics, we have a specialised and differentiated cryopreservation laboratory. Each patient has their space in the tank and does not share space with another patient. This way the eggs are protected from potential cross contamination and are easy to locate when needed.
