China has received 1.2 billion doses of the new crown vaccine, but Americans are worried about affecting male fertility

According to a report from the National Health Commission on the 29th, as of June 28, 2021, China’s 31 provinces (municipalities and autonomous regions) and the Xinjiang Production and Construction Corps have reported a total of more than 1.

According to media reports, only 56% of people in the United States expressed their desire to get the new crown vaccine, that is, 44% of people are unwilling to get the new crown vaccine, and one of the reasons why they hesitate to get the new crown vaccine is that the new crown vaccine has not been tested for reproductive toxicity.

Will the new crown vaccine affect male fertility? Research results are just the opposite

In order to study the impact of the new crown vaccine on sperm, a research team at the University of Miami recruited 45 healthy volunteers aged 18-50 who were planning to receive the COVID-19 mRNA vaccine before the first dose and 90 days after the second dose.

It was found that among the healthy men who participated in the study, no one had a significant decrease in sperm parameters

It can also be seen from the research data that contrary to what people are worried about, after the volunteers are vaccinated with the new crown vaccine, the semen volume, total live sperm count, sperm concentration and sperm motility have all increased significantly

The new crown vaccine not only does not reduce sperm quality, but it seems to have a little "improvement" effect? In fact, the study recruited only 45 volunteers, the number was small, the follow-up time was short, and there was no control group, so there were some limitations

In addition, it should be noted that semen analysis is the basis for assessing male fertility, but it is not a complete indicator of male fertility

Can men who plan to become pregnant receive the new crown vaccine?

Although the University of Miami study did not find that the new crown vaccine has a negative impact on male fertility, in view of the limitations of the current research on the reproductive toxicity of the new crown vaccine, it is recommended that men do not receive the new crown vaccine during pregnancy

Considering the importance of vaccinating new crown pneumonia in preventing new crown pneumonia and improving herd immunity, it is recommended that male friends who have a pregnancy plan delay pregnancy
