How Male Reproduction Works
The male reproductive system includes both external and internal organs that, with the help of hormones, allow physically mature males to produce children.

How Male Reproduction Works
The two main functions of the male reproductive system are to produce and store sperm and transfer them to the female’s body during sexual intercourse.
SpermMale gametes

How Male Reproduction Works
Hormones produced in the pituitary gland stimulate the production of testosterone, which initiates physical changes that signal maturity.
TestosteroneThe male sex hormone

External Reproductive Organs
A male’s external reproductive organs include the testes, the penis, and the scrotum.
TestesTwo small glands that secrete testosterone and produce sperm

External Reproductive Organs
The testes are located in the scrotum.
ScrotumAn external skin sac

External Reproductive Organs
The penis is composed of spongy tissue that contains many blood vessels.
Penis
A tube-shaped organ that extends from the trunk of the body just above the testes

External Reproductive Organs
When the penis becomes erect, semen can be ejected from the body.
Semen
A thick fluid containing sperm and other secretions from the male reproductive system

Internal Reproductive Organs
Sperm must travel through the vas deferens, the urethra, the seminal vesicles, and the prostate and Cowper’s glands before they are released from the body.

Maintaining Reproductive Health
Male reproductive health involves care and monitoring throughout a male’s lifetime.
As with any other body system, the male reproductive system needs care.

Male Reproductive System Problems
The organs of the male reproductive system can be affected by both functional and structural problems.
Males should watch for the signs of reproductive system problems, as well as signs of infections from STDs.

Male Reproductive System Problems
An inguinal hernia occurs when part of the intestines push through a tear in the abdominal wall.
Surgery can repair an inguinal hernia.

Male Reproductive System Problems
Sterility occurs as a result of too few sperm or sperm of poor quality.
SterilityThe inability to reproduce

Male Reproductive System Problems
With early detection, most testicular cancer is treatable through surgery, radiation, or chemotherapy.
Testicular cancer occurs most often in males between the ages of 14 & 40 years old.
Figure skater and Olympic gold medalist Scott Hamilton is a testicular cancer survivor.

How to Do a Testicular Self-Exam (TSE)
The American Cancer Society recommends that males perform a self-exam for testicular cancer once a month.

The scrotum holds the testes outside the body so that they are kept at a temperature slightly lower than body temperature.
