The male reproductive system consists of both primary and secondary sex organs. The primary organs are the testes, which produce sperm through spermatogenesis within the seminiferous tubules. Sperm then travel through the epididymis, vas deferens, and other ducts. The testes are controlled by hormones from the pituitary gland. Secondary sex organs include the seminal vesicles, prostate, and bulbourethral glands which produce fluid for semen. The penis is also a secondary sex organ used for copulation.
