Ejaculation
Ejaculation refers to the release of semen from the penis. It is triggered by rhythmic contractions of the muscles in the reproductive ducts and the pelvic floor, and usually occurs in connection with sexual arousal and orgasm. The semen is expelled in spurts.
The term is used in medical, sexual, and everyday language. Ejaculation is not always identical with pleasure or orgasm; it can be experienced differently depending on the person, the situation, and overall health. If there is pain, unusual changes, or difficulty with ejaculation, medical evaluation is advisable.
