It constantly supplies your body with sperm able to travel through the vagina to an unfertilized ovum in a woman's ovaries to conceive.
There is no specific frequency with which a man should ejaculate. There is no solid evidence that failure to ejaculate causes health problems. However, ejaculating frequently can reduce the man's risk of getting prostate cancer. Ejacu-lation can be through having sex or masturbating a few times a day.
