The age of the father also matters

And the latest research suggests that it does so faster than previously thought. From the age of 35, the quality of your sperm accumulates mutations that can influence the health of your children. The older they are, the greater the risks.

Until recently, it was considered that it was after 55 years when the father’s age could have an impact on the baby’s health. The cause? Greater accumulation of chromosomal alterations in sperm.

Now, a new study from the Stanford University School of Medicine suggests that the risks begin at 35 and are significant after 45.

Being a retrospective study, these results should be viewed with caution.

More than 40 million births have been analyzed in the US, and mothers are grouped into age ranges that are too broad to assess whether there are other risks. However, they highlight the need to study the incidence of paternal age and the male biological clock in more depth.

Preservation of male fertility is a very simple process that consists of adding a medium (cryoprotectant) to the seminal sample that allows the sperm to freeze without the formation of ice crystals, preventing the deterioration of the sperm.

Subsequently, it is introduced into liquid nitrogen at -196ºC, where the sample will be kept until it is decided to use it, maintaining the same quality as when it was frozen.
