Five beers a day is usually fertile, but it is usually recommended to abstain from alcohol for three months before preparing for childbirth. Alcohol can cause some damage to sperm and eggs, and if severe sperm and egg damage occurs, abnormalities such as embryo cessation and fetal developmental abnormalities may occur. Since the production cycle of sperm in men is about 70 to 90 days and follicle development in women takes about 30 days, it is best to abstain from alcohol for 3 months before preparing for childbearing, which is conducive to obtaining better quality embryos. If abnormalities are found in the fetus during regular pregnancy tests, it is recommended to go to the hospital in time to improve the examination to clarify the cause of the disease and then give targeted treatment or standardized treatment.
