The danger of conception after male drinking needs to be determined according to the amount of alcohol consumed. If a man conceives after drinking a small amount of alcohol once in a while, it is generally not harmful to the fetus and the fetus can be retained, but close pregnancy checkups should be done to follow up the development of the fetus. If the man is a frequent drinker or a heavy drinker, it may jeopardize the development and health of the fetus. Alcohol can affect the quality of male sperm and cause defects in fertilized eggs, and pregnancy after heavy drinking may result in abnormalities such as poor embryonic development or fetal arrest, or malformation of the fetus. It is generally recommended to stop drinking 3 months before pregnancy, and if you get pregnant after heavy drinking, you need to do a good job of obstetric examination, and terminate the pregnancy in time if there are abnormalities.
