What is the expulsion of seminal fluid from the male urethra known as?

The expulsion of seminal fluid from the male urethra is referred to as ejaculation. This process occurs during sexual climax and involves the rhythmic contraction of the muscles at the base of the penis and in the pelvic region, which helps propel the semen out of the urethra. Ejaculation is typically accompanied by a pleasurable sensation and signifies the end of the male orgasm.

Erections are related to the engorgement of erectile tissue in the penis that allows for sexual intercourse but do not involve the expulsion of fluid. Emission refers to the process whereby semen is moved into the urethra in preparation for ejaculation but is not the act of expelling the fluid itself. Discharge can have various meanings and does not specifically refer to the expulsion of seminal fluid, which is why it is not the correct term in this context.
