Unclear effect. Hepatitis c does not have any obvious effect on pregnancy and has a very low (5%) chance of being transmitted to the infant (and it is usually found to be asymptomatic in the infant). Some studies have found that infants of hepatitis C mothers are of lower birth weight, small for gestational age, more likely to need a ventilator or nicu care. More studies are needed to establish this definitively.
Depends. The risk of transmission of hepatitis c depends on the viral load and activity of the virus. The risk of transmission is higher from mothers top babies than fathers. For infected fathers ivf and icsi is recommended. But there is no good treatment so fetal effects when they occur can be severe over time.
