Question

why male reproductive system is called as urinogenital system ??

Answer 1

The word urogenital is used because the urinary and reproductive systemsin males merge. The male urogenital system consists of several parts, including the testes, epididymis, vas deferens, ejaculatory ducts, urethra, penis, prostate and accessory glands..

Answer 2

The genitourinary system or urogenital system is the organ system of the reproductive organs and the urinary system. These are grouped together because of their proximity to each other, their common embryological origin and the use of common pathways, like the male urethra.
