On the contrary, the couples in the study had slightly lower chances of conception if the male partner had been infected with the coronavirus within 60 days – which offers even more reason to get vaccinated against Covid-19, because the disease could affect male fertility in the short term. term, according to the study, published Thursday in the American Journal of Epidemiology.
There is no link between Covid-19 vaccines and infertility. here's why

“These results indicate that male SARS-CoV-2 infection may be associated with short-term decline in fertility and that COVID-19 vaccination does not impair fertility in either partner,” said the researchers – from the Boston University School of Public Health and other institutions across the United States – wrote in the study. SARS-CoV-2 is the name of the virus that causes Covid-19.

“This adds to evidence from animal studies, studies of humans undergoing fertility treatment, and COVID-19 vaccine trials, none of which have found an association between COVID-19 vaccination and a lower fertility,” the researchers wrote. “Similarly, multiple studies have documented no appreciable association between COVID-19 vaccination and risk of miscarriage.”

The study included data on 2,126 women, ages 21 to 45, in the United States and Canada. The women enrolled in the study from December 2020 to September 2021, and the researchers followed them through November 2021.

Infertility not a risk with Covid-19 vaccines for children

During the study, the women completed online questionnaires every eight weeks about their reproductive and medical history, among other factors, and they were given the option of inviting their male partners to complete questionnaires. Among the participants, 73% of women and 74% of their male partners had received at least one dose of the Covid-19 vaccine.

The researchers analyzed the responses to the questionnaire and found no association between having been vaccinated against Covid-19 and the probability of conceiving a child during a menstrual cycle. Yet the data showed that although previous Covid-19 infection was not strongly associated with the likelihood of conceiving in women, men who had Covid-19 were associated with a “transient reduction” in probability of conceiving.

the The National Institutes of Health announced the results of the study in a press release on Thursday and noted that couples in which the male partner tested positive within 60 days were 18% less likely to conceive during that menstrual cycle, but there was no difference in rates conception for couples in which the male partner had tested positive more than 60 days before a cycle, compared to couples in which the male partner had not tested positive.
Further research is needed to determine what might be driving these results, but fever is known to reduce sperm count and is a symptom of Covid-19, according to the NIH.

“The results provide reassurance that vaccinating couples seeking pregnancy does not appear to impair fertility,” said Dr. Diana Bianchi, director of the Eunice Kennedy Shriver National Institute of Child Health and Human Development. NIH, which funded the study. “They also provide information to doctors who counsel patients who are hoping to conceive.”
