Learning About the Male Reproductive System

What does the male reproductive system do?

The male reproductive system makes sperm and delivers it out of the body. It allows a man to have sex and father children.

This system is made up of:

• The penis.
• Testicles. This is where sperm is made.
• The scrotum. This is a sac at the base of the penis that holds the testicles.
• Epididymides. This is where the sperm mature.
• Seminal vesicles and the prostate gland. They make the liquid semen that carries the sperm.
• The vas deferens tubes. These carry semen to the urethra and out of the penis during sex.

What problems can happen with the reproductive system?

Problems may include:

• Injuries to the genitals. This could happen when you play sports, do other activities, or take a fall.
• Infections of the testicle (orchitis), epididymis (epididymitis), prostate gland (prostatitis), or other areas.
• Sexually transmitted infections (STIs). These include chlamydia, genital herpes, genital warts, and gonorrhea.
• Sperm problems. They could cause you to be infertile.
• Erection problems (impotence or erectile dysfunction).
• Torsion of a testicle. This emergency happens when a testicle twists in the scrotum. The twisting can cut off its blood supply.
• Cancer of the testicle, penis, or prostate.

How can you prevent reproductive system problems?

• If you play contact sports, make sure to wear a cup or other protection for your genitals.
• Having one sex partner (who does not have STIs and does not have sex with anyone else) is a good way to avoid STIs.
• Do not smoke. Smoking can lower your overall sexual health. If you need help quitting, talk to your doctor about stop-smoking programs and medicines. These can increase your chances of quitting for good.
