Despite the fact that history has taught us that after a crisis the natality, now with the health crisis of the coronavirus, experts point out that the fertility rate in 2020 will even be lower than in 2019. Not only is it a health crisis, but also an economic crisis that is added to that of 2018, so the phenomenon baptized as “coronaboomers”Will follow the same line of births that we have been observing in recent years: fewer children at an older age.

In our country, the average age at which one has the first child exceeds 32 years, according to data from the latest survey of fertility of the National Institute of Statistics (INE). A situation that is complicated if we take into account that in 2019 the lowest number of births was registered since 1975.

Socio-economic factors such as the delay in the emancipation of young people – a consequence of the difficulty in finding work that is not precarious and, therefore, their economic independence – make it impossible for a woman to start her own family during her life. most fertile stage, included between 20 and 35 years.

The lack of real information on how the fertility exacerbates the problem. Few patients come to a center for Assisted reproduction knowing that beyond the age of 35 the quality and quantity of your eggs will begin to decline and, with it, the probability of getting pregnant. Also, a large percentage of the population will have difficulties conceiving after 38 years of age.

“The maternal age factor is present in the 70% of couples who consult for reproductive problems in our Assisted Reproduction center ”, says Dr. Sergio Roger, Medical Director of the clinic IVF-Spain Alicante.

Faced with a social reality that is difficult to modify, the Reproductive medicine brings to the table an answer and a solution to stop the biological clock: the oocyte vitrification. Advances in Assisted Reproduction such as the increase in the survival rate of eggs or embryos after freezing allow that today there are women who can preserve their fertility for when they decide to be mothers. It is advisable to do it at an age that guarantees obtaining higher quality oocytes to increase the chances of success.

Regarding the amount of ovules necessary to achieve pregnancy it is difficult to give an exact figure, but experts consider that if around 15-20 are obtained, an 80% chance of achieving a pregnancy can be reached after vitrification.

The feeling of instability and uncertainty that our society is going through dilutes, even more, the possible idea of ​​starting a family in the coming years. However, beyond this crisis, which will also pass, we must think that the ovarian reserve is not finite and that the idea of ​​saving fertility allows us to preserve it for when the right time comes.
