The duration of a drink affecting sperm is related to the amount of alcohol consumed, and usually affects sperm for at least a week. After drinking alcohol, alcohol will enter the body’s liver and kidneys with the blood circulation, affecting the whole body, especially after alcohol abuse, which will cause more damage to the body and will have a killing effect on the weak sperm. After the damage, the sperm’s vitality will be significantly reduced, so it takes some time to recover, and the recovery time is about a week. In short, alcohol abuse is harmful to the human body and needs to be consumed in moderation. If you need to prepare for pregnancy, you should not have sex until at least a week after drinking to ensure that the quality of sperm is not affected by alcohol. In addition, during the recuperation period, you need to drink plenty of water, rest in bed, get enough sleep, and eat nutritious foods such as beans, milk, eggs, lean meat, fresh fruits and vegetables and foods with lots of vitamins to ease the damage of alcohol.
