Men infected with the SARS-CoV-2 virus can lead to infertility, even if they are only mildly ill, the researchers found. According to an Israeli study, the sperm count of men infected with Covid-19 has halved after 30 days since they were diagnosed with the disease.
Dr. Dan Aderka, from the Sheba Medical Center in Tel Aviv also found that the sperm’s ability to move, or its ability to move on its own, is also hindered from slowing down.
However, it is unclear whether Covid-19 will permanently damage fertility, and even the flu causes a temporary decrease in sperm count.
Experts believe that the decrease in sperm production in Covid-19 patients is caused by fever and that even the common flu can do the same.
Some previous studies have suggested that viral infections may affect fertility, but there isn’t any solid evidence to back this claim. Many people assume that fever is the cause of the decrease in sperm production because cells need 34 ° C (93.2 ° F) to produce, although their numbers may rise again after infection. coincide.
Several large studies are currently underway to determine whether the virus affects fertility. The first study, supported by the National Institutes of Health (NIH), will examine the medical records of more than 20,000 pregnant women to determine the difference between them and 1500 women who are already pregnant and have Covid. -19.
The aim of the study is to understand how viruses affect the health of pregnant women and how changes in access to health care are affecting them.
An ASPIRE study is also underway that will look at cases in the first trimester, when the baby’s organ system forms and the placenta develops. Researchers hope to understand the impact of Covid-19 on this critical early stage of development.
According to the Jerusalem Post, the affirmative study report was published in the journal Fertility and Infertility, claiming changes were seen in men with mild illness, but no mention was made. number of participants. However, the magazine responded and said there was no record of Dr. Aderka submitting the report to them.
There have not been any journals published yet, which means that scientists around the world have yet to come to conclusions. However, doctors stressed that the reports of men with lower sperm counts were likely due to fever, a symptom of Covid-19. This makes it harder for the body to produce sperm and can end after the infection is gone.
Professor Allan Pacey, a male researcher at the University of Sheffield, former president of the British Fertility Association says he is not surprised if Covid-19 causes a temporary decrease in sperm production: “Even the flu a temporary decrease in sperm count. But the question is whether it will be permanent and recoverable.
Previous research has shown that any damage caused to the testicles by an infection is not permanent. Dr. Aderka, from the Sheba Medical Center, who conducted the study claims that Covid-19 can damage testicles by binding to ACE2 receptors on their cells. These receptors act as a gateway for viruses to enter cells, like receptors in the lungs, heart, and intestines. However, scientists have previously shown that SARS-CoV-2 needs to go into the bloodstream, but there is no clear mechanism for this.
Professor Ian Jones, a virologist at the University of Reading said that the virus that causes Covid-19 does not normally move in the blood: “The main place for the virus to replicate is the respiratory tract. The virus normally travels in the blood but in general this is not what the virus does.
