The number of days it takes to return to normal after ejaculation is uncertain and can vary from person to person. It can be as short as two days or as long as five days. For young men, it can take about two days to recover after sperm discharge. But if you are in poor health, it takes about five days to recover. It takes about a week for the sperm to mature, so men should avoid having sex again for a short time after ejaculation. If you have sex frequently, the quality of sperm may decrease and the number of sperm will become less and less. It is recommended to have sex 1~2 times a week, not frequently, otherwise fatigue will cause the quality of sex to decline, but also can cause some harm to the health of men. For couples preparing for pregnancy, sexual life needs to be restrained, it is best to arrange sexual life in the ovulation period, to ensure the quality of sperm.
