The placenta is a temporary body part that allows the baby to receive nourishment from the mother while in the womb. So, even if the SARS-CoV-2 virus targets the placenta, I doubt it’s going to permanently prevent people from having kids.
A concern to me is that male and female germ cells contain ACE2 receptors, the receptors that SARS-CoV-2 binds to. So, I think there is a possibility that Covid-19 infection in children could reduce their fertility, possibly even leave them sterile.
