Which adrenal cortex layer secretes estrogens and androgens?

Explanation:
The innermost layer of the adrenal cortex, the zona reticularis, is responsible for estrogens and androgens. It produces weak androgens such as DHEA and androstenedione, which can be converted to more potent androgens or estrogens in peripheral tissues (like adipose tissue and gonads). The other layers have different primary hormones: the outer zona glomerulosa makes mineralocorticoids (aldosterone), the middle zona fasciculata makes glucocorticoids (cortisol), and the adrenal medulla secretes catecholamines (epinephrine and norepinephrine).
