It's called ejaculation
Ejaculation is the term meaning releasing semen from the penis.
Semen is not produced in the penis itself. Semen is produced in the testes, which are outside the penis, and it travels through a tube called the ejaculatory duct before being released from the penis during ejaculation.
The mixture of sperm cells and other fluids that are ejaculated from the penis is called semen. It is produced by the male reproductive system and contains sperm cells along with fluids from the prostate gland and other glands.
The scientific term for the hole in the penis where urine and semen are expelled is called the urethral meatus.
That tube is called the Urethra
It is a natural occurence of a substance called semen.
Prostate secretion is called semen. It is a fluid with a milky appearance and helps to nourish and carry the sperm via penis (from testicles) during ejaculation. Prostatic secretion actually mixes with semen. The secretion liquefies the semen to allow it move through the penis during ejaculation.
The tube that runs from the bladder to the tip of the penis is called the urethra. It serves as a passage for both urine and semen to pass through.
I'm pretty sure it's the Urethra...
