Under normal circumstances, patients suffering from hepatitis B can have sex, but we should pay attention to the following issues: first, the condition of hepatitis B patients is stable and light, the patient has no uncomfortable symptoms, liver function is not a problem, the body’s hepatitis B virus content is normal or low. Secondly, during the process of sexual life, the health and safety of the sexual partner should be protected, and condoms can be used to avoid the transmission of hepatitis B to each other through semen or vaginal secretions. However, the most effective protection is to have the sexual partner vaccinated against hepatitis B as soon as possible to obtain protective antibodies against the hepatitis B virus and to obtain long-term safety protection.
