MythCancers of the male reproductive system only affect older men.
Fact Cancer of the testes (testicular cancer) most often occurs in teens and young men.
Epididymis: Long, coiled tube that rests on the backside of each testicle. It transports and stores sperm cells that are produced in the testes.
Vas Deferens: Long, muscular tube that travels from the epididymis into the pelvic cavity, to just behind the bladder. They transport mature sperm to the urethra.
Ejaculatory Ducts: These are formed by the fusion of the vas deferens and the seminal vesicles. These ducts empty into the urethra.
Urethra: The tube that carries urine from the bladder to outside the body. When the penis is erect during sex, the flow of urine is blocked from the urethra, allowing only semen to be ejaculated at orgasm.
Seminal Vesicles: Sac-like pouches that attach to the vas deferens near the base of the bladder. They produce sugar-rich fluid that provides sperm with a source of energy to help them move. This fluid makes up most of the volume of a man’s ejaculatory fluid.
Prostate Gland: A walnut sized structure that is located below the urinary bladder in front of the rectum. It contributes additional fluid to the ejaculate to help nourish the sperm.
Bulbourethral Glands: Also called Cowper’s glands, pea-sized structures located on the sides of the urethra just below the prostate. They produce a clear, slippery fluid that empties directly into the urethra to lubricate and neutralize any acidity due to residual drops of urine in the urethra.
Sperm travel through the vas deferens to the seminal vesicles.
Seminal vesicles add a fluid that provides a source of energy for the active sperm.
The prostate gland adds a fluid that protects the sperm.
The bulbourethral glands add a lubricating fluid that aids the passage of sperm through the urethra.
The Pathway of Sperm
Sperm are produced in the testes. They mature and are stored in the epididymis.

Days 1–4 The uterine lining is shed during menstruation.
Days 5–13 An egg matures in one of the ovaries, and the uterine lining starts to thicken.
Days 14–15 The ovary releases the mature egg during ovulation.
Days 16–22 The egg travels through the fallopian tube to the uterus, and the uterine lining continues to thicken.

Caring for the female reproductive system involves
The reproductive cells in females.

The female sex hormone that signals certain physical changes at puberty and controls the maturation of eggs.
A hormone that signals changes to a woman’s reproductive system during the menstrual cycle and pregnancy.
The process during which one of the ovaries releases a ripened egg.
The passageways that carry eggs away from the ovaries.
The hollow, muscular, pear-shaped organ in which a fertilized egg develops and grows.
The hollow, muscular passage leading from the uterus to the outside of the female body.
The process during which an ovary releases a mature egg that travels to the uterus; if the egg is not fertilized, the uterine lining is shed and a new cycle begins.
The time of life during which the ovaries slow down their hormone production and no longer release mature eggs.
A medical procedure in which a sample of cells is taken from the cervix and examined under a microscope.
