Step 1
The male reproductive system is made up of many sex organs that are involved in human reproduction. These organs can be found on the exterior of the body as well as within the pelvic. The male reproductive system is a collection of exterior and internal organs that work together to create, maintain, transport, and deliver viable sperm for fertilization. The epididymis, ductus deferens, ejaculatory duct, and urethra are all used to transfer sperm from the testes to the urethra.
