Which zone of the adrenal cortex produces gonadocorticoids?

The zona reticularis is the region of the adrenal cortex responsible for the production of gonadocorticoids, which are sex hormones such as androgens. This layer is the innermost zone of the adrenal cortex, situated beneath the zona fasciculata and above the adrenal medulla. Gonadocorticoids play a crucial role in the development and regulation of sexual characteristics and reproductive functions.

In contrast, the zona glomerulosa, which is the outermost layer, primarily produces mineralocorticoids such as aldosterone, which are involved in the regulation of salt and water balance in the body. The zona fasciculata is responsible for the synthesis of glucocorticoids like cortisol, which are critical for metabolism and stress response. The adrenal medulla, on the other hand, is part of the central part of the adrenal gland and produces catecholamines like epinephrine and norepinephrine, involved in the fight-or-flight response.

Understanding the specific functions associated with each zone of the adrenal cortex helps clarify the role of the zona reticularis in hormone production, underscoring why it is correctly identified as the site for gonadocorticoid synthesis.
