What is it?
The vitrification of ovules is a very recurrent procedure for women of reproductive age who wish to postpone their motherhood since it is a reality that over time fertility decreases considerably, in each menstrual cycle hundreds of oocytes are lost, after the age of 35, only the total ovarian reserve is available, however, not only does the quantity decrease, the quality of the oocytes is also affected as time passes and the chances of having a baby with a chromosomal problem increase year by year.
Due to these reasons, the best age for egg preservation is before the age of 35, when the quantity and quality of oocytes begin to decline.
The uncertainty that the future produces is a good reason to bet on vitrification or if the decision to be a mother or not has yet been made.
Why should you do it?
As the woman ages, the number and quality of oocytes decrease. It is an option for all those women who for medical or personal reasons cannot or do not want to get pregnant immediately but who do contemplate it at some point in their life. If you are still not sure, you can still consider it as an option in case your opinion is different in the future.
It is recommended to women who wish to postpone their motherhood, suffer from any disease, are still not sure of wanting children in the future, or must undergo treatment where their reproductive capacity may be affected, such as cancer that directly affects fertility..
The first step in the vitrification of ovules consists of ovarian stimulation so that a greater number of mature oocytes are produced. These must be extracted through a puncture, once they are in the laboratory they are protected against the low temperatures to which they will be exposed to different substances called cryoprotectants to prevent the cell membrane from breaking, that is why the vitrification of female gametes are performed quickly to avoid ice formation and are preserved in liquid nitrogen for as long as required. The number of oocytes to be frozen will depend on the ovarian response to the stimulation of each woman, it is estimated that about 80% of the preserved eggs can be used for fertility treatment. To achieve a pregnancy with preserved eggs it is necessary to use In Vitro Fertilization, ICSI or PICSI,.
