What is the male reproductive system in order? The male reproductive system includes the penis, scrotum, testes, epididymis, vas deferens, prostate and seminal vesicles. 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. During puberty, increased gonadotropin secretion stimulates a rise in sex steroids creation from the testes. The increased secretion of testosterone from the testes during puberty causes the male secondary sexual characteristics to be manifested. Testis has two major functions: to produce sperm by meiotic division of germ cells within the seminiferous tubules, and to synthesise and secrete androgens that regulate the male reproductive functions. The site of production of androgens is the Leydig cells that are located in the interstitium between seminiferous tubules.
