There are some little-known benefits of male semen besides making women pregnant. Recently, the major U.S. knowledge website “The Unbiased? Health” recently published an article listing some new findings about semen. Relieves depression. Scientists have found that semen has stimulant properties, and some of its substances can boost mood and make people happy. Surveys have shown that women who are regularly exposed to semen (sex without condoms) are less likely to suffer from depression and less likely to commit suicide. Prevention of gynecological diseases. Studies have found that male semen contains an important antibacterial substance, semen cytokinin. It kills pathogenic bacteria such as staphylococcus, streptococcus and pneumococcus, and helps protect the female genitals from microorganisms. Women who have not had sex for a long time are more likely to suffer from vaginitis, endometritis and tubal infection. Relief of premenstrual syndrome. The seminal plasma in semen contains prostaglandins and some enzymes. Some studies have shown that prostaglandins can cause strong contractions of the uterus, prompting blood to flow out of the pelvic area faster and reducing various discomforts during menstruation. Stable marriage. Generally, a woman will only let a man ejaculate into her body if she is assured of sexual safety. This act mostly occurs between married couples, and the entry of semen into the body increases the bonding between the two parties and gives women a sense of happiness in their marriage. However, researchers point out that semen, although good, can also spread disease, so it is important to make sure both partners are healthy and have taken other contraceptive measures before semen enters the body.
