Why do some people think that COVID shots have destroyed the fertility of young men?

The usual suspects…
COVID Shots Have Not Destroyed the Fertility of Young Men
As anti-vaccine influencers often do, to try and scare you into thinking that COVID vaccines have “destroyed the fertility of young men,” they are simply misusing an actual study about sperm motility.
“The motile sperm concentration and total motile sperm count (TMSC) in ejaculates—both measures of sperm quality—declined by as much as 22% from 2019 to 2022.”

To be clear though, the study never blames COVID vaccines for this change.
“We should be mindful that many other aspects of life also altered around this time. For example, widespread lockdowns may have led to changes in working patterns, diet, and levels of physical activity. Several studies have shown that each of these factors can impact sperm motility.”

They seem to favor blaming lifestyle changes brought on by lockdowns, ignoring the fact that COVID infections themselves could be to blame simply because they were “closed and did not process any semen samples for 11 weeks in the spring of 2020.”

The thing is, they continued to collect samples through 2022…

A time when Denmark had a rather large COVID surge.
“Adjusting for test sensitivity (estimates ranging from 74%–81%) and November seroprevalence, we estimate that 66% (95% confidence intervals (CI): 63%–70%) of the healthy, similarly aged Danish population had been infected between November 1, 2021, and March 15, 2022.”

And after this surge, we seem to see some of the biggest changes in this Denmark semen study, especially in the Accepted donors group who provided the great majority of semen samples!
“We cannot determine from the available data the causes of the decline in semen quality of donor candidates from 2019 to 2022. However, as this period coincides with lockdowns and changes in work patterns during the coronavirus disease 2019 pandemic, it is possible that changes in motile sperm concentration and TMSC were the result of changes in the lifestyles of the men whose semen was analyzed.”

It is puzzling that these researchers ignored this and went solely with their lockdown/lifestyle change theory, especially since there were no lockdowns in Denmark in 2021 or 2022!
Does COVID Disease Affect Fertility?
Not surprisingly, there are studies that confirm that COVID disease might affect fertility.
And although most who are infected return to normal fertility, at least one study reported that it could take three or more months to return to baseline after they recover from COVID.
For women, the American College of Obstetrics and Gynecology (ACOG) recommends that pregnant and lactating women be offered the COVID-19 vaccine. Similarly, the Society for Maternal Fetal Medicine has recommended that pregnant women have access to the currently approved Pfizer COVID-19 vaccine. Finally, the American Society for Reproductive Medicine does not recommend withholding the vaccine from patients who are planning to conceive, and emphasizes that ”patients undergoing fertility treatment and pregnant patients should be encouraged to receive vaccination based on eligibility criteria.“

Which is why your best best to avoid fertility problems is to get vaccinated and protected against COVID.
