Families who intend to have children through fertility treatments can breathe a sigh of relief and receive Covid-19 vaccines. In the first study to examine how immunizers affect fresh embryo transfer IVF, published in JAMA, scientists at the University of Iowa in the United States found no negative correlation in pregnancy rates between these vaccinated and unvaccinated patients.
With the work, the researchers hope the findings will provide new information and data for healthcare professionals to advise fertility patients about the safety of vaccines.
Previous research has shown that Covid-19 immunizers do not negatively affect fertility outcomes in IVF patients using frozen embryos or a couple’s chance of conceiving a child.
Frozen vs fresh embryo transfer
In vitro fertilization is a procedure designed to help women who are unable to conceive by natural means. It uses different processes to harvest human eggs from a woman and fertilize them outside her body. Once fertilized, this egg becomes an embryo that can be frozen for later use in a frozen embryo transfer cycle or implanted in the woman’s uterus a few days after fertilization, a procedure called a fresh embryo transfer.
In this study, Emily Jacobs, a reproductive endocrinologist at the University of Iowa and lead author, and her team analyzed data from patients who received fresh embryo transfer between December 2020 and September 2021. Of this population, 142 women were vaccinated against Covid-19. and 138 patients were not vaccinated. “Despite the previously published literature, at the time this study was conducted, patients, both fertile and infertile, still had a significant concern about vaccination and the potential impact on future fertility,” she said.
The researchers, however, found no evidence suggesting that vaccination negatively affected the results of in vitro fertilization of fresh embryo transfer. Additionally, the research team says there were no significant differences between pregnancy and miscarriage rates between vaccinated and unvaccinated patients. “Our data confirm the previously published literature that Covid-19 vaccination does not adversely affect any aspect of female fertility – egg numbers, fertilization, embryonic development, implantation and clinical pregnancy,” said Emily.
According to the paper, physicians should be encouraged to advise their patients to be vaccinated if they are planning to become pregnant, as pregnant women have a higher risk of serious illness and death than non-pregnant women, and the vaccine is safe for anyone. stage of pregnancy.
