Answer:
A. It isn't necessary to vital signs.
Step-by-step explanation:
The Male Reproductive System is made up of internal and external organs. They undergo a slow maturation ending in puberty, that is, when the sex cells are available to originate another being. This system differs from other systems in the body because it does not need vital signs.
The organs that make up the male reproductive system are: urethra, penis, seminal vesicle, prostate, vas deferens, epididymis and testicles.
