How does it work?!


Question:

How does it work?

how actually does the ejaculation cycle work? I mean like how does stuff come out when you have sex? does the muscle in your penis relax thus releasing available liquids in the genitals? how does it work?!


Answers:

It's a little more complicated than muscles, because there are no muscles in the penis itself, none.

There are tubes (corpora cavernosa) in the penis that fill up with blood, this is what causes the penis to erect.

Sperm from the testes is released by a tiny thin muscular tissue on the vas deferens, it relfexes and releases the sperm.
"During ejaculation the smooth muscle in the wall of the vas deferens contracts reflexively, thus propelling the sperm forward. The sperm are transferred from the ductus deferens into the urethra, collecting fluids from the male accessory sex glands en route."

What causes the ejaculate to flow out of the penis - "During ejaculation proper, the semen is ejected through the urethra with rhythmic contractions". These blood vessels in the penis perform rhythmic contractions causing a wave like motion.

There you have it.
