If a man is hepatitis B minor third-positive, he can prepare for pregnancy just like a normal healthy person. If a woman is hepatitis B minor third-positive, the test requires normal liver function before she can get pregnant. If the liver function is not normal, she needs to be treated and can have children only when the liver function is back to normal and stable, the same applies to IVF, there is no difference. Women doing IVF need to do the normal mother-to-child blocking after a successful pregnancy, which requires the newborn to be vaccinated with hepatitis B vaccine and hepatitis B immunoglobulin after birth.
