Covid-19 can cause male infertility, study shows

Covid-19 may have an impact on male fertility, according to a review of studies conducted by the Evidence-Based Medicine Center at the Faculty of Medical Sciences of Santos. The change occurs both in sperm count and in the drop in testosterone levels, shows the survey recently published in the International Brazilian Journal of Urology.

In the articles evaluated, there are reports of changes in patients' semen, such as low levels of sperm or even changes in their mobility.

The changes were more pronounced in those who were seriously ill. In some cases, there was information that the patients already had children, which rules out the possibility that this was a problem prior to Covid.

The good news is that researchers rule out the possibility of sexual contagion, as the presence of the virus in semen was extremely rare.

and why this happens?

One of the explanations for the urological complications of covid is the systemic inflammation caused by the disease.

Furthermore, the cells that the virus uses to invade the body – the angiotensin-converting enzyme receptors – are present in several organs, such as the lungs, but also in the urinary and reproductive systems, suggesting that these locations could also be directly affected by the virus. .

How was the search done?

The review was carried out in the main databases from more than 8 thousand articles. Of these, 49 met the authors' criteria, such as presenting relevant outcomes, totaling more than 3 thousand individuals.

The drop in hormone levels has also been associated with the severity of the disease. According to one of the articles, this rate was inversely associated with admission to the Intensive Care Unit (ICU), suggesting that testosterone levels may be an early marker of the severity of the disease.

“We don’t know whether the impacts are transitory or whether they will have a long-term effect,” says Luca Schiliró Tristão, one of the study’s authors. “There is still a lot to be studied, there is a lack of long-term research because of this type of study”, he highlights, regarding the survey that was carried out with patients still hospitalized.

Problems such as increased urinary frequency and inflammation in the testicles, but of lesser relevance, also appeared in the review.
