Researchers said that when a pregnant woman becomes infected with the Covid-19 virus, the gender of the fetus may affect the activity of the immune system.

The new study included 68 women about to give birth, as thirty-eight women were infected with the Corona virus during the third trimester of pregnancy, while 30 of them remained healthy from the virus, and in both groups, half of the fetuses were male and the other half were female.
The researchers found that in the affected women, the male placenta had significantly higher levels of certain genes and proteins associated with increased immune activity than the female placenta.
While this increased immune activity may provide male fetuses with better protection against infection with the Corona virus, the resulting inflammation may pose risks to the fetus while it is in the womb and to the baby after birth, explained senior study author Dr. Andrea Idlow, a maternal-fetal medicine specialist at Massachusetts General Hospital in Boston.
The researchers also found that infected pregnant women pass on significantly lower immunity to the virus to male fetuses than female fetuses, which may affect the infant’s risk of SARS-Covid-2 infection.
“The gender of the fetus affected the mother’s ability to produce antibodies to the Corona virus and transmit it to her child,” Idlow said in a hospital press release.
The researchers noted that this study was motivated by previous research that showed that adult males, children and infants have a higher rate of infection with the Corona virus and develop more severe disease than females.
The next step is to examine the antibodies caused by the COVID-19 vaccine and see how they are affected by the timing of the vaccine as well as the gender of the fetus.
What happens to the placenta when mothers are vaccinated against the Corona virus?
“We want to know what happens to the placenta when mothers are vaccinated against COVID-19 at each trimester and how the sex of the fetus affects this response,” Idlow said.
