The human Penis is made up of three chambers. There are two on top and one on the bottom. The two areas (chambers) on top are made of a spongy tissue that fills up with blood when you get an erection. The medical term for the two chambers on top is the “corpora cavernosa”. That is the main part of the anatomy of a human penis.
The third chamber, which runs along the bottom of the penis is called the “corpus spongiosum”. This section encloses the urethra, which is a tube that urine and sperm exit the body from.
The Cowper’s glands secrete a small amount of pre-ejaculate fluid prior to orgasm. This fluid neutralizes the acidity within the urethra itself.
The foreskin is a roll of skin which covers the head of the penis in uncircumcised men.
The frenulum is a thin strip of flesh on the underside of the penis that connects the shaft to the head.
The prostate gland produces a fluid that makes up the semen. The prostate gland squeezes shut the urethral duct to the bladder so urine won’t mix in with the semen.
The Scrotum is a sac that hangs below the penis. It’s purpose is to hold the testes and keep them at 34C, the optimal temperature for producing sperm.
The two testes produce sperm and testosterone. Each testicle produces nearly 150 million sperm every 24 hours.
