The male reproductive system generates semen in the testicles, which is stored in the epididymis for several days. During ejaculation, semen is expelled through the vas deferens and seminal vesicle into the ejaculatory duct and urethra. The muscular movements of ejaculation propel the sperm forward and out of the body. The functions of the male reproductive system are to produce, maintain and transport sperm and semen, discharge sperm in the female reproductive tract, and produce male sex hormones like testosterone.

4. How does it work? Semen is generated in the testicles and is led to the epididymis, where it is stored for several days. Once a mature, ejaculation occurs and is expelled through the vas deferens to the spermatic cord. Here, the vas deferens joins the seminal vesicle to form the ejaculatory duct. This crosses the prostate and empties into the urethra. Upon ejaculation, the muscular movements propel the sperm forward. Seminal vesicle Deferens duct Epididymis Testicle

5. Functions To produce, maintain and transport sperm and protective fluid (semen). To discharge sperm within the female reproductive tract. To produce and secrete male sex hormones. For example: testosterone.
