Sperm is not absorbed. When sperm enters a woman’s genitals, it is not absorbed by the body. After a single ejaculation, the semen will be expelled from the body after accompanying the woman’s activities. Only a small portion of the sperm will travel down the uterus to the fallopian tube area, where it will combine with the egg and eventually form a fertilized egg. Most of the other sperm will liquefy and die, and will be discharged along with the vaginal secretions of the woman. Don’t wear too tight pants, balanced nutrition, reduce psychological stress, avoid staying up late, and moderate exercise can all improve sperm quality to some extent, which is conducive to conception. If you suspect that there is a problem with the quality of the sperm, you can have a semen test, including trait examination, microscopic examination, chemical examination, as well as immunological examination, microbiological examination and so on to determine the problem.
