Recent studies have shown that some people fear that the Covid-19 vaccine may cause infertility. However, various publications from different institutions have clearly stated that this is not the case. The Robert Koch-Institut (RKI) has also confirmed that the claim is false. The clinical trials conducted before the approval of the vaccines did not provide any evidence that the vaccines promote infertility. In fact, some studies have shown that the vaccine has no effect on fertility.
The Covid-19 vaccine is one of the most important measures in the fight against the pandemic, along with protective masks. However, a high vaccination rate of about 90 percent is necessary. In Germany, only 74 percent of the population has received their first dose of the vaccine as of January 4, 2022. This is partly due to some vaccine opponents who believe that the current vaccines cause infertility.
A study published in the Reproductive Biology and Endocrinology journal in May 2021 analyzed data from 36 couples who received the vaccine while undergoing treatment for artificial insemination. The quality and quantity of eggs and sperm were almost identical before and after vaccination. Another study from Israel in December 2021 with 129 women fully vaccinated with Biontech also concluded that the vaccine does not affect fertility. The researchers at the Schiba Hospital near Tel Aviv examined the level of the anti-Müller hormone, which indicates how many eggs a woman produces. The results showed that there was no change in the hormone level after vaccination.
According to a publication in the JAMA journal by researchers from the University of Miami, men also do not need to worry about the vaccine affecting their fertility. The sperm of 45 men between the ages of 18 and 50 were equally fit before and after receiving two doses of an mRNA vaccine. Overall, the studies clearly show that there is no evidence that the approved vaccines affect the fertility of women or men.
