Steroid hormone synthesis

    • Steroid Hormone - an overview | ScienceDirect Topics

      Pregnenolone is a steroid hormone made in your adrenal glands and is the precursor to DHEA, cortisol and the sex hormones. Your body synthesises this hormone from cholesterol and it is often referred to as the “mother of all steroid hormones”. From ages 35 to 75, most people have a 65% decline in pregnenolone. Functions:

      Defect of StAR prevents all steroid hormone synthesis and leads to sexual infantilism. GC receptor defect causes overstimulation of ZF/ZR leading to excessive DOC and cortisol (ineffective). MC receptor defect leads to overproduction of aldosterone but no effect in ZF/ZF. Hypercortisolism (Cushing’s Disease) – Elevated serum cortisol levels.
