Can hepatitis B women with high viral replication first reduce viral load before pregnancy?

In general, women with hepatitis B who have high viral replication are advised to reduce their viral load before pregnancy, as this significantly lowers the risk of mother-to-child transmission and ensures the health of both mother and baby. The detailed explanation is as follows:

For women with high hepatitis B virus replication, becoming pregnant directly may allow the virus to remain highly active during pregnancy, increasing the likelihood of fetal infection via the placenta. It also raises the risk of complications in the pregnant woman, such as abnormal liver function or hepatitis during pregnancy. Clinically, doctors will evaluate each patient's condition and prescribe antiviral medications that are safe for the fetus—such as tenofovir disoproxil fumarate—prior to conception. Once the viral load has decreased to a low level and liver function has stabilized, the woman can be guided toward planning her pregnancy. This approach not only reduces the risk of mother-to-child transmission from 20%-40% to less than 1%, but also alleviates the burden on the liver during pregnancy and lowers the chance of severe liver disease in the mother.

Therefore, women with high hepatitis B viral replication should not attempt pregnancy blindly. Instead, they should first visit a specialist clinic for a thorough assessment of their condition. Under medical guidance, they should complete antiviral treatment and meet the necessary criteria for pregnancy preparation before planning to conceive. Throughout this process, strict adherence to medical advice is essential, along with regular monitoring of viral load and liver function, to ensure both treatment effectiveness and safety during preconception planning.
