On the basis of the intra-adrenal steroid hormone concentrations, we found that androstenedione is the most abundant Δ 4 adrenal androgen synthesized via the classic steroidogenic pathway throughout the first and second trimesters. Objective Preterm infants have relative adrenal and kidney immaturity. Steroidogenesis in the adrenal, gonads, and placenta is a directional process designed to synthesize one or a few final steroid products unique to each cell type. The morbidity of the various forms of adrenal hyperplasia is best understood in the context of the steroidogenic pathway, shown below, used by the adrenal glands and gonads.

Recently, we linked their urine sodium loss to a hypoaldosteronism at variance with an appropriate stimulation of the renin-angiotensin system. Brooks, M. &. The majority, CYP21A1 mutations, result in 21-hydroxylase deficiency, with: inability to synthesise cortisol and aldosterone; diversion of increased steroid precursors, including 17-hydroxyprogesterone (17-OHP), into androgen production (figure 1). An appreciation of these pathways serves as the basis for understanding the different forms of congenital adrenal hyperplasia (CAH) and isolated hypoaldosteronism in which there are defects in the function of the enzymes involved in adrenal steroid hormone synthesis.
