Male Reproductive System

Path of SPERM

The sequence of structures through which sperm travels in the male reproductive system.

SPERM

Male sex cell responsible for fertilization.

SEMEN

Thick fluid produced by the seminal vesicles, prostate gland, and bulbourethral glands, which nourishes and protects sperm.

ERECTION

The process in which erectile tissue fills with blood, causing the penis to become rigid.

EJACULATION

The process by which sperm exits the body through muscle contractions, pushing semen out through the urethra.

NOCTURNAL EMISSION

Also known as a "wet dream," it is the occurrence of ejaculation during sleep, particularly common during puberty.

SCROTUM

The external pouch that holds the testes and epididymis.

TESTES

The male reproductive organs that produce testosterone and sperm.

EPIDIDYMIS

The tube located on the back of each testicle, where sperm matures and is stored.

VAS DEFERENS

The tube that transports sperm from the epididymis to the urethra.

SEMINAL VESICLES

Glands that produce fluid to nourish sperm.

PROSTATE GLAND

Gland that produces fluid to nourish sperm and increases the pH level of semen.

BULBOURETHRAL/COWPER'S GLANDS

Glands that produce fluid to lubricate the urethra and neutralize acid from residual urine.

URETHRA

The tube that transports urine from the bladder and expels semen from the body.

PENIS

The external organ composed of erectile tissue.

Erectile tissue

Sponge-like tissue that fills with blood, causing an erection.

Circumcision

The removal of the foreskin covering the tip of the penis.

Health benefits of circumcision

Lower risk of certain sexually transmitted infections (STIs), urinary tract infections (UTIs), and penile conditions.
