What affects fertility in women or men: the vaccine or …

Dubai, United Arab Emirates (CNN) There is no link between vaccines against Covid-19 and a decrease in the possibility of pregnancy, according to a study published Thursday, in the scientific journal America Journal of Epidemiology.

This study revealed that the chances of pregnancy decline for the couple, if the man is infected with the Corona virus within 60 days, which gives an additional argument for receiving the anti-Covid-19 vaccine, as long as the disease may affect the fertility of the man in the short term.

The researchers participating in the study from the School of Public Health at Boston University and other institutes in the United States wrote, These discoveries indicate that the infection of men with the emerging coronavirus, SARS-CoV-2, can be linked to a short-term decline in fertility, while the vaccine against Covid does not affect them. 19 on the fertility of men and women.

The researchers added, This discovery is in addition to the evidence found by previous studies conducted on animals, and others that have been ongoing, about fertility treatments and tests for the anti-Covid-19 vaccine, and none of them found a link between the anti-Covid-19 vaccine and reduced fertility. . They added that, as well, several studies have documented no association between the COVID-19 vaccine and the risk of miscarriage.

The study was based on the data of 2,126 women between the ages of 21 and 45 years, in the United States of America and Canada. The women participated in the study between December 2020 and September 2021, and the researchers followed up with them through November 2021.

During the study, women filled out online forms every 8 weeks, addressing reproductive issues, health history, and other factors. They were also given the option to invite their male partner to fill out the form. Among the participants, 73% of women and 74% of men received a single dose of the COVID-19 vaccine.

The researchers analyzed the answers and found that there was no link between receiving the Covid-19 vaccine and the possibility of pregnancy during one menstrual cycle. Also, previous infection with Covid-19 does not affect the possibility of pregnancy among women, while there is a link between men who were infected with Covid-19, and a transient decline in their fertility.

And the National Institutes of Health announced, in a press statement, Thursday, that the discoveries noted a decrease of 18% in the man who was infected with Covid-19 within 60 days, compared to another who did not have corona.

More research is needed to determine the reason behind this decline, but what is known, according to the institutes, is that the temperature reduces the number of semen, which is one of the symptoms of Covid-19.

These findings confirm that there is no link between a couple getting the vaccine and fertility, said Dr. Diana Bianchi, director of the National Institutes of Healths Eunice Kennedy Shriver National Institute of Child Health and Human Development, which funded the study. And she continued, It broadens the horizon of knowledge for doctors who see patients who aspire to have children.
