Washington: A recent study has raised rumors that Covid-19 vaccination led to infertility.
This study was published in the ‘American Journal of Epidemiology’ confirmed that Covid-19 vaccination did not seem to affect fertility.
Prospective studies of couples who try to get pregnant have not found the relationship between vaccination and fecundability Covid-19 – Probability of conception per menstrual cycle – on partners of women or men who receive vaccines Pfizer-Bionontech, Moderna, or Johnson & Johnson.
Conversely, findings show that Covid-19 infection among men can temporarily reduce fertility – results that can be avoided through vaccination.
“Many reproductive individuals have quoted concerns about fertility as the remaining reasons are unknown,” said the study writer, Dr.
Amelia Wesselink, assistant professor of epidemiology in Busfh.
“Our study shows for the first time Covid-19 vaccination in one partner is not related to fertility among couples who try to get pregnant through sexual relations.
Time to pregnancy is very similar to vaccination status,” he added.
Wesselink and colleagues analyzed survey data on Covid-19 vaccination and infection, and fecundelability, among female and male participants in the BUSF-based pregnancy study (Presto), a study that was underway that was ongoing that registered them to get pregnant and Follow it.
prejudice through six months after giving birth.
Participants include 2,126 women in the US and Canada who provide information about sociodemography, lifestyle, medical factors, and their partner characteristics from December 2020 to September 2021, and participants are followed in this study until November 2021.
Researchers counts per menstruation cycle The probability of conception uses the last period of self-reported menstrual period, the length of the menstrual cycle is typical, and pregnancy status.
The fertility rate among female participants who received at least one vaccine dose was almost identical to women who were not vaccinated.
Fecundity is also similar to male partners who have received at least one dose of Covid-19 vaccine compared to male participants who are not vaccinated.
Additional analysis considers the number of vaccine doses, vaccine brands, history of infertility, employment, and geographical areas also show the effects of fertility vaccination.
While Covid-19 infection is not strongly associated with fertility, men who test positive Covid in 60 days of certain cycles have reduced fertility compared to men who have never been tested positively, or men who are most valid for 60 days.
This data supports previous studies that have linked Covid-19 infection in men with poor sperm quality and other reproductive dysfunction.
“This data provides convincing evidence that Covid vaccination in both partners does not affect fertility between couples who try to get pregnant,” said Senior writer Dr.
Lauren Wise, professor of epidemiology on busph.
“Prospective study design, a large sample size, and a geographically heterogeneous research population is the strength of the study, such as our control for many variables such as age, socio-economic status, existing health conditions, work, and stress levels,” he added.
New data also helps extinguish concerns about the covid-19 vaccine and fertility that arises from female anecdotal reports that experience changes in menstrual cycles after vaccination.
