Each male body quality may be different, so how long abstinence from sperm full of self overflow is not the same, need specific analysis, not a generalization. In general, a healthy male usually needs to discharge semen once in 3-7 days. If you don’t have semen discharge, semen may appear to flow out on its own, which is generally more common in adolescence and is a reflection of the self-regulatory function, which is usually not harmful to the human body. Some men may be abstinent for 2-4 weeks before they experience semen overflow, and there are individual differences. However, as men grow older, the rate of semen production will slow down and the frequency of semen overflow will gradually decrease. If there is no depression, weakness of the waist and knees, or coldness of the hands and feet, there is usually no need to worry too much. However, if the above symptoms occur, it is recommended to visit the urology department in time for the doctor to determine whether treatment is needed. Sperm overflow is usually a normal phenomenon, and if it is not particularly frequent, it usually does not need to be treated with medication, but only requires adjustment of living habits, such as regular sex life and avoiding frequent sexual stimulation.
