Jakarta, TOPNews Indonesia —
If you hesitate to follow vaccination because of the vaccine news Covid-19 that interfere with male fertility, now you don’t have to worry. New study finds Covid-19 vaccine doesn’t damage quality sperm.
Recent studies published in the journal JAMA The study examined the number and quality of men’s sperm after receiving Pfizer and Moderna’s Covid-19 vaccines. As a result, no damage was found.
This study examined sperm samples of 45 men aged 25-31 years who were declared healthy. Samples were taken before the injection of the first dose of vaccine and 70 days after the injection of the second dose. Researchers then checked sperm count, concentration, and motility.
“We found no sperm changes in healthy young men who had received two doses of the mRNA vaccine,” said study author Ranjith Ramasamy, reproductive expert at the University of Miami Health System. TOPNews.
Although not conducting trials on other vaccine recipients, such as Johnson & Johnson and Astrazeneca, Ramasamy is confident that the same results will be found.
“We think the mechanism of action of these vaccines is quite similar, although the genetic material is different. So, based on biological reasons, we don’t think there will be a different effect with other vaccines,” Ramasamy said.
However, Ramasamy said, larger studies are still needed to include men of various ages to confirm the results of the study.
Commenting on the study, University of Sheffield, UK andrologist Alan Pacey said that the results of the study could provide convincing data regarding the relationship between sperm and the Covid-19 vaccine.
“This [hasil studi] showed that sperm quality did not change after getting two injections of the Covid-19 vaccine,” Pacey said.
Corona Virus Affects Sperm
While the vaccine did not have a significant impact, the corona virus was found to be harmful to male reproduction.
A small study published in January found an increase in inflammation in the sperm cells of men who tested positive for Covid-19. Changes can be seen from the concentration, mobility, and shape of sperm. This is due to the ACE2 receptor which is also found in the testes.
The study also found that the severity of the disease makes the impact experienced by sperm is also different.
