The purpose of the organs of the male reproductive system is to perform the following functions:
-To produce, maintain, and transport sperm (the male reproductive cells) and protective fluid (semen)
-To discharge sperm within the female reproductive tract during sex
-To produce and secrete male sex hormones responsible for maintaining the male reproductive system.
Unlike the female reproductive system, most of the male reproductive system is located outside of the body. These external structures include the penis, scrotum, and testicles.
