The male reproductive system is mostly located outside of the body. These external organs include the penis, scrotum and testicles. Internal organs include the vas deferens, prostate and urethra. The male reproductive system is responsible for sexual function, as well as urination.

The male reproductive system includes a group of organs that make up a man’s reproductive and urinary system. These organs do the following jobs within your body:

They produce, maintain and transport sperm (the male reproductive cells) and semen (the protective fluid around sperm).
They discharge sperm into the female reproductive tract.
They produce and secrete male sex hormones.
The male reproductive system is made up of internal (inside your body) and external (outside your body) parts. Together, these organs help you urinate (rid your body of liquid waste materials), have sexual intercourse and make children.
