Generally, sperm can be replenished in the epididymis after 3-5 days of abstinence, but it is not absolute and depends on individual circumstances. Sperm are produced every day, especially for those who have more secretion of gonads during puberty, sperm production may be more. After being generated in the testes, normal sperm will undergo a series of changes, mature and be energized in the epididymis. This cycle is usually 24-48 hours, i.e. 1-2 days to produce a large number of active sperm. In daily life, we should pay attention to adjusting our dietary habits and work and rest habits, and not to drink alcohol or stay up late to improve the quality of sperm. If there is a situation of sperm overflow, do not be too panic, it may be related to the vigorous secretion of puberty, abstinence for too long, etc. It is recommended to adjust in time. The number of times of normal sex needs to vary from person to person, and the needs of each person vary, but regardless of age, sex needs to be done regularly. The number of times a healthy young adult has sex may be relatively frequent, and as age increases, the number of times a person has sex may gradually decrease. If the number of sex is too frequent for a long time, physical fatigue, fatigue, weakness, back pain, etc., it is recommended to make adjustments and reduce the number of sex to avoid unnecessary harm to the body.
