Men who contracted coronavirus had fertility problems for 60 days, study finds; the expert explains why
RELATED: COVID-19 vaccines do not affect fertility in women or men, study finds
A research paper funded by the National Institutes of Health shows that men who tested positive for COVID-19 within 60 days of their partner’s cycle were 18% less likely to conceive during that cycle.
“Our hypothesis is that contracting COVID and potentially having fever associated with COVID could affect sperm genesis, which is the process by which sperm develop. Other studies have shown that fever, qu “whether it’s COVID or something else, can affect sperm quality for the next two months,” said Amelia Wesselink, PhD, co-author and assistant research professor of epidemiology at the Boston University School of Public Health. .

Dr. Wesselink was the co-author of this study. His team followed 2,100 couples between the ages of 21 and 45 for about a year, with 75% of them getting vaccinated during that time.
Luz Pena: “Have you noticed any sort of impact on fertility in women who have contracted COVID or been vaccinated?”
Dr. Wesselink: “In our study, we observed no effect of vaccination or infection in women. This was independent of time since vaccination or time since infection. We looked at different brands of vaccination, and really overall, very little association between either exposure with fertility in women.”
They also did not find fertility problems in vaccinated men.

Dr. Michael Eisenberg, director of the male reproductive medicine and surgery program at Stanford, explains why body temperature is critical.
Luz Pena: “Why does fever play a role in this? »
Dr. Eisenberg: “Because fever reacts to infection as the body normally does, it can slow sperm production and is somewhat toxic to sperm.”
Dr. Eisenberg also pointed out that men who contract COVID could also experience challenges beyond fertility within 60 days of infection.
“There may be impacts not only on sperm production, but also on sexual function. We are also seeing links to erectile dysfunction in some of these more acute episodes. All of these episodes probably contribute, to some degree, to this lower pregnancy change in this first window,” Dr. Eisenberg said.

According to this study, this decline in fertility in men after contracting COVID improved after these 60 days.
These experts have stressed the importance of getting vaccinated to avoid these setbacks if you want to conceive.
