Ques: Q: The deepest region of the adrenal cortex is the zona reticularis, which produces small amounts of a class of steroid sex hormones called what?   Read this paragraph and choose the correct option from the provided answers:  Hormones of the Zona Reticularis The deepest region of the adrenal cortex is the zona reticularis, which produces small amounts of a class of steroid sex hormones called androgens. During puberty and most of adulthood, androgens are produced in the gonads. The androgens produced in the zona reticularis supplement the gonadal androgens. They are produced in response to ACTH from the anterior pituitary and are converted in the tissues to testosterone or estrogens. In adult women, they may contribute to the sex drive, but their function in adult men is not well understood. In post-menopausal women, as the functions of the ovaries decline, the main source of estrogens becomes the androgens produced by the zona reticularis.   Choices:  - estrogen  - dioxins  - testosterone  - androgens   A:
Ans: androgens
