Whether a person with hepatitis B can get married should be considered from two aspects: on the one hand, because hepatitis B is an infectious disease, will marriage transmit the hepatitis virus to the spouse? On the other hand, it is better for people with hepatitis B to get married in what kind of physical condition? During a relationship, a person with hepatitis B should take the initiative to tell the other person about his or her condition and urge the other person to go to the hospital to check for markers of the hepatitis B virus (the main items should include: HBsAg, anti-HBs, anti-HBc). Common results may appear in the following 3 situations, which have different meanings: ① if anti-HBs is positive, it means that the other party is already resistant to the hepatitis B virus and will not be infected with the hepatitis B virus and can get married. ②If HBsAg is positive, it means that the other party is also infected with hepatitis B virus, although there is no mutual transmission between the two, but at this time the two people who are ready to get married, still both should further check the situation of liver function to determine the timing of marriage. ③ such as hepatitis B virus markers are negative, indicating that the other party has not been infected with the hepatitis B virus and no resistance, if the marriage is easy to be infected at this time, so it is not appropriate to get married immediately. At present, the hepatitis B vaccine can be administered to produce sufficient anti-HBs in the body to achieve the effect of resistance and avoid hepatitis B infection. Some people with hepatitis B or their family members may think that they should get married only after the HBsAg or HBeAg has turned negative through treatment. Since there is no effective treatment for hepatitis B at home and abroad, and no drugs can “cure” hepatitis B, the idea of waiting for HBsAg or HBeAg to turn negative before getting married is extremely unrealistic. The most reliable way to avoid transmission of the hepatitis B virus because of marriage is to go to the hospital for examination and vaccination against hepatitis B for those who need it. The liver function of the person with hepatitis is an important factor that should be considered as to whether the person with hepatitis can get married. Due to the numerous preparations before and after the marriage, various social activities, heavy mental burden, easy to strain; more sexual life during the newlywed period will consume a lot of physical strength and energy, for patients with abnormal liver function, it will increase the burden on the liver and may aggravate the liver disease. Therefore, it is not advisable to get married immediately during the active period of acute hepatitis or chronic hepatitis. Acute hepatitis has a short course and can be married after six months of cure. Chronic hepatitis patients, should be stable, liver function completely normal 1 year after marriage is good. If only hepatitis B virus markers (such as HBsAg, etc.) positive and normal liver function of virus carriers, there is no restriction on when to get married, but attention should still be paid to prevent overexertion and reduce the frequency of sexual life to prevent induced hepatitis attacks. It should be emphasized that during the newlywed period, alcohol consumption should be avoided and spousal protection should be strengthened, such as using condoms during sex to reduce the chance of transmission. Is it possible for a person with hepatitis B to have children? For a man with hepatitis B, if his liver function is normal and stable and his wife has protective antibodies (anti-HBs), it is possible to have children because the sperm quality of a hepatitis B patient is not affected. If the wife lacks protective antibodies, she needs to produce protective antibodies through hepatitis B vaccination before pregnancy. For women with hepatitis B, the situation is much more complicated. Although no evidence has been found that the hepatitis B virus causes fetal malformations, pregnancy is contraindicated in women with acute hepatitis, active chronic hepatitis, or cirrhosis of the liver. The reason is that when a woman is pregnant, she needs to provide a lot of nutrients for the fetus, which will increase the burden on the liver of the pregnant woman, and the immune function and endocrine changes of the body during pregnancy often aggravate the existing liver disease, and even progress to heavy hepatitis with a high mortality rate. Although the hepatitis B vaccine and hepatitis B immunoglobulin (HBIG) are two weapons that can be used to prevent mother-to-child transmission of hepatitis B virus, about 5% of newborns may still be infected with hepatitis B virus, which is often the last thing people want to see. Therefore, for women with hepatitis B, pregnancy is not advisable when liver function is abnormal, and the appropriate time to conceive can be chosen after 1 year of normal liver function and under the guidance of a physician. To protect the next generation from being infected by hepatitis B virus, newborns should be given hepatitis B vaccine as early as possible after delivery and complete the vaccination according to the procedure (hepatitis B vaccination is now free in China).
