Covid fertility vaccine

For a year now, since the vaccination against Covid-19 was launched, there are many questions and fears, both on the short-term and long-term effects. If on the short-term ones we now have very clear answers, a question that many women have asked themselves concerns the consequences that could have on a future conception. So let's talk about Covid vaccine, fertility and any problems.

Covid vaccine and menstrual cycle abnormalities

There have been many reports of women saying they experienced abnormal menstrual cycles after vaccination against Covid, already at the first doses or at the booster. These are mostly advances or longer durations, but despite these variations, confirmed by some research, there do not seem to be any other consequences. 



Covid vaccine and fertility

What is certain, however, is that vaccinating against Covid-19 has no impact on fertility, neither feminine nor masculine. This is confirmed by numerous studies, the latest carried out by some researchers at Boston University and published in the American Journal of Epidemiology. 



For the study, 2000 couples were examined, some vaccinated, others not, and then they compared the data on conception. The results show that there are no differences, not even by comparing different types of vaccine or a different number of doses: who is vaccinated, whether the woman or the man or both are equally likely to conceive that those who are not vaccinated have, also taking into account other variables that are always present regardless of the vaccine (in fact the researchers used data from the Pregnancy Study Online - PRESTO).

Covid infection and fertility

Instead, what emerged from the research is that in couples where the man has contracted the Covid infection, the fertility rate is decreased, even if apparently only for a temporary period. What has been noted, in fact, is that the conception rate decreases in menstrual cycles in which the man had Covid up to 60 days earlier. This is a slight decrease, 18%, but still considerable when compared to the data of the vaccinated, who do not register any decline in fertility. If you go back more than two months before the attempts, however, the data realigns and the probabilities remain the same.

Fever and decreased fertility

It is established that the fever can reduce the sperm count and their motility, for this probably the men who contract the Covid have a drop in fertility in the following two months, which however seems to return without any consequence. 

In any case, the study confirms the importance of get vaccinated, in particular women who intend to become pregnant or who are already pregnant: the vaccine in pregnancy is safe and indeed protects against the more aggressive forms of Covid-19 that can affect the pregnant women in particular, and also the fetus, with very serious consequences. 

Il vaccine against Covid-19 does not reduce the fertility, neither feminine nor masculine, this is why it is always recommended to do it to protect yourself and loved ones, even when looking for a child.
