17-Hydroxy Progesterone is a steroid derived primary from enzymatic
metabolism of Progesterone and 17-Hydroxy Pregnenolone. It is converted
enzymatically to Androstenedione and 11-Deoxycortisol. It is produced
in both the gonads and adrenal glands. It is excreted into the urine in
conjugated and unconjugated forms of 17-Hydroxy Progesterone and
as Pregnanetriol. This assay measures the total of the conjugated and
unconjugated forms. It is stimulated by ACTH and suppressed by
Dexamethasone. Levels of urine 17-Hydroxy Progesterone are greatly
increased in patients with Polycystic Ovarian Disease and Congenital
Adrenal Hyperplasia and show exaggerated responses to ACTH in
these cases. 17-Hydroxy Progesterone is the marker steroid for
determining cases of 21a-Hydroxylase Deficient Congenital Adrenal
Hyperplasia. Urine levels are frequently elevated in patients with
