Final answer:
The gonads, including the testes and ovaries, are responsible for producing sex hormones, developing secondary sexual characteristics, and assisting in sexual maturation, but not for the production of urine, which is a role of the kidneys in the excretory system.
Step-by-step explanation:
The gonads, which are the male testes and female ovaries, play multi-faceted roles in the endocrine system. Among these roles are the production of sex hormones such as testosterone in males and estrogen and progesterone in females, the development of secondary sexual characteristics, and the progression of the body through various sexual stages like puberty and menopause. These functions are crucial for sexual maturation and reproductive capabilities.
However, one function that is not a role of the gonads is the production of urine. This activity is actually a function of the excretory system, particularly the kidneys. Urine production is related to the removal of waste and regulation of bodily fluids, which is separate from the hormonal and reproductive functions of the gonads.
Therefore, the correct answer to the question 'Which of the following is NOT one of the roles of the Gonads in the Endocrine System?' is (D) Production of Urine.
