What is the Origin of Steroidogenesis Substrate Diversion?

This term is rooted in the biochemistry of the adrenal cortex and gonadal steroidogenic pathways, specifically the "Pregnenolone Steal" or "Cortisol Steal" hypothesis. It describes the competitive nature of the steroidogenic enzymes for the common precursor molecules. Clinical endocrinology uses this concept to understand and address hormonal imbalances resulting from chronic stress or enzyme polymorphisms.

What is the Mechanism of Steroidogenesis Substrate Diversion?

The diversion is primarily mediated by the rate-limiting enzymes in the pathway, such as cytochrome P450 enzymes. Under chronic physiological stress, the sustained high signaling of the Hypothalamic-Pituitary-Adrenal (HPA) axis upregulates the enzymes responsible for cortisol synthesis. This upregulation effectively pulls the shared substrate, often pregnenolone or progesterone, away from the pathways leading to DHEA, testosterone, and estrogen production, resulting in a clinically relevant imbalance.

Steroidogenesis Substrate Diversion

Meaning

A clinical concept describing the shift in the metabolic flow of cholesterol and its immediate derivatives (substrates) away from the production of one class of steroid hormones and toward another, often influenced by enzymatic activity or substrate availability. For instance, increased stress can divert precursors toward cortisol production (glucocorticoids) at the expense of sex hormones (androgens and estrogens). This diversion impacts the entire steroid hormone cascade.
