Semen retention is an ancient practice that's similar to celibacy and is motivated by the belief that ejaculation weakens a man's health. Proponents of semen retention believe that semen contains essential nutrients, vitamins, and minerals that contribute to overall health and vitality. They believe that by retaining semen, the body can redirect and use these elements for various physiological functions, such as improved mental clarity, physical endurance, and emotional stability. Other health benefits that some ascribe to semen retention include improved fertility and testosterone levels, and more intense orgasms. However, there isn't enough scientific evidence to recommend semen retention to all men.
