Covid vaccines do not cause male or female infertility

Covid vaccines do not cause male or female infertility

Researchers have found no link between COVID-19 vaccines and infertility in studies done so far.
The vaccines of covid-19 do not cause infertility or women or men, as shown by scientific studies and experts EFE explain the general advice of doctors and pharmacists, whose findings contradict rumors that went viral internationally.

EFE Verifica has received a query on its WhatsApp channel about the possibility that these vaccines cause infertility, after numerous publications on social networks in various countries have generated an alarm in this regard.

In Spain and Latin America, the messages that warn that these drugs cause infertility or that there is a desire to sterilize the vaccinated have been disseminated by denialist websites and associations, such as Doctors for Truth or Biologists for Truth.

FACTS: Researchers have found no relationship between COVID-19 vaccines and infertility in studies so far, although they believe more information needs to be gathered.

However, there is also no theoretical approach to suggest that drugs have these effects.

"In an unequivocal way, we can affirm that there is no association between vaccines against covid-19 and presumed infertility," emphasizes Juan Martínez Hernández, member of the advisory commission on this disease of the Collegiate Medical Organization (WTO).

To do this, he argues that neither messenger RNA (mRNA) vaccines -such as Pfizer and Moderna-, nor viral vector vaccines -as is the case of AstraZeneca and Janssen preparations- contain elements that can act in this way in the human organism.

He adds that neither the adverse effect databases nor the scientific literature reflect reproductive problems linked to covid-19 vaccines.

In the UK, the Association of Clinical and Reproductive Scientists and the British Fertility Society have jointly published an information guide stating that "there is absolutely no evidence, or any theoretical reason, that neither vaccine can affect the fertility of women or men ".

Among the investigations carried out, a study prepared by the University of Miami and published on June 17 by the Journal of the American Medical Association (JAMA) stands out.

It concludes that Pfizer or Moderna vaccines are "safe for male reproduction" and do not have a negative impact on male fertility.

The researchers examined 45 healthy male volunteers between the ages of 18 and 35 and assessed sperm parameters before and after vaccinating them.

On the contrary, the head of that study, Ranjith Ramasamy, has warned that the disease itself carries more risks, since "covid-19 could cause male infertility and sexual dysfunction, but vaccines do not."

Other studies carried out with animals "do not indicate direct or indirect harmful effects with respect to toxicity for reproduction", recalls Carlos Fernández Moriano, from the General Council of Pharmaceutical Associations.

Fernández Moriano points out, however, that studies are yet to be completed, something that the US health information service for the media and Health Desk verifiers also indicates.

"Until now, no data suggests any damage or risk," explains this service in response to a query from EFE Verifica.

Although it specifies that "scientists are collecting data to continue studying the relationship between covid-19 vaccines and fertility to ensure that the vaccines do not represent any risk or potential harm to fertility."

In any case, as the Health Desk itself points out, "the American College of Obstetrics and Gynecologists (ACOG) has advised all women over 18 years of age, women planning to become pregnant, all pregnant women and nursing mothers get vaccinated ", while warning of the risks of contracting covid-19 during pregnancy.

In conclusion, there is no scientific evidence or theoretical approach to suggest that COVID-19 vaccines can cause infertility in women or men, compared to the risks that the disease itself carries, although the researchers are continuing their analyzes to find out more information.
