Penis Anatomy Diagram and Description

Diag

Corona: The raised ridge of flesh separating the head of the penis from the shaft.

Corpora Cavernosa (sing. Corpus Cavernosum): The two sponge-like masses of erectile tissue that lie along the body of the penis and join together in the head of it. These expandable erectile tissues contain spaces/cavities/chambers which fill with blood during sexual excitement and thus causing erection. Penis enlargement techniques focus on expanding the corpora cavernosa chambers with the use of natural enlargement programs, penis enlargement pills, and/or devices.

Cowper’s Glands: Two small glands attached to the urethra, which produce and secrete a small amount of clear, sticky fluid called pre-ejaculate (”pre-cum”), which neutralizes the acidity of the urethra during sexual arousal.

Ejaculatory Ducts: Two ducts (passageways) that start in the vas deferens and empty into the urethra – passing through the prostate gland. This is the path semen travels during ejaculation, before it exists the body through the penis.

Epididymis: A coiled, narrow tube that connects each testis to its vas deferens. Immature sperm produced by the testis proceed to the epididymis, where they are stored for maturation processes to complete.

Foreskin (Prepuce): In uncircumcised men, the loose fold of skin which surrounds the head of the penis.

Glans Penis (Glans, also known as the head of the penis): The sensitive tip of the penis. It is usually covered by the foreskin in uncircumcised men.

Prostate Gland: The prostate gland contributes about one-third of the volume of semen. During ejaculation, the prostate gland shuts the urethral duct to the bladder to prevent the semen from mixing with urine which has low PH that may kill the sperms.

Scrotum: The loose pouch of skin that hangs below the penis, and contains the testes. The main function of the scrotum is to keep the testes at temperature around 34 C (which is slightly lower than the temperature on the rest of the body; about 37 C), at which temperature the testes perform most effectively.

Seminal Vesicles: A pair of tubular glands that produce about 60 percent of the volume of semen.

Testicles (Testes; sing. Testis): The two sexual glands located inside the scrotum. The testicles mainly produce sperm and male sex hormones, such as testosterone.

Urethra: A muscular tube which carries urine from the urinary bladder, and semen from the prostate gland and seminal vesicles to outside the body through the meatus, the opening of the urethra at the end of the head of the penis.

Vas Deferens (pl. Vasa Deferentia): One of the paired, muscular tubes that carry mature sperm from the epididymis to the ejaculatory ducts. These are the tubes that are cut during the procedure known as vasectomy.
