The main subset of androgens, known as adrenal androgens, is composed of 19-carbon steroids synthesized in the zona reticularis, the innermost layer of the adrenal cortex. Adrenal androgens function as weak steroids (though some are precursors), and the subset includes dehydroepiandrosterone (DHEA), dehydroepiandrosterone sulfate (DHEA-S ...
Adrenal steroids such as glucocorticoids and mineralocorticoids are commonly used as treatments in diseases such as Congenital adrenal hyperplasia. [2] CAH commonly causes overproduction of androgens, glucocorticoid treatment is used to reduce Adrenocorticotropic hormone (ACTH) and reduce the production of androgens allowing for symptoms of CAH to be managed though treatment is required to be ...
The adrenal cortex is the outer region and also the largest part of the adrenal gland. It is divided into three separate zones: zona glomerulosa, zona fasciculata and zona reticularis. Each zone is responsible for producing specific hormones. It is also a secondary site of androgen synthesis. [2]
The fetal zone produces large amounts of adrenal androgens (male sex hormones) that are used by the placenta for estrogen biosynthesis. [39] Cortical development of the adrenal gland is regulated mostly by ACTH, a hormone produced by the pituitary gland that stimulates cortisol synthesis. [40]
Androgens, or sex hormones, are synthesized in the innermost layer of the adrenal cortex known as the zona reticularis. These hormones, such as estrogen in females and testosterone in males, are commonly known for promoting sexual characteristics and the maturation of reproductive organs of the respective gender. [2]
synthesis of corticosteroids (glucocorticoids and androgens) in adrenocortical cells: 15 Angiotensinogen and Angiotensin. AGT Peptide: liver: angiotensin receptor → IP 3: vasoconstriction. release of aldosterone from adrenal cortex dipsogen. 16 Antidiuretic hormone (or vasopressin, arginine vasopressin) ADH Peptide: posterior pituitary
Cells in the zona reticularis produce precursor androgens including dehydroepiandrosterone (DHEA) and androstenedione from cholesterol. [2] DHEA is further converted to DHEA-sulfate via a sulfotransferase, SULT2A1. [3] These precursors are not further converted in the adrenal cortex if the cells lack 17β-Hydroxysteroid dehydrogenase.
[citation needed] These C11-oxy androgens can contribute to the pathology of congenital adrenal hyperplasia, polycystic ovarian syndrome, and prostate cancer. [7] [8] The androgen backdoor route is activated during normal prenatal development and leads to early male sexual differentiation.
