Background: Patients with 21-Hydroxylase deficiency (21OHD) present increased levels of cytochrome P450 21-hydroxylase substrates, like progesterone and 17α-hydroxyprogesterone. Previous studies could show that these hormones are involved in the production of androgens via the backdoor pathway. As a second source of androgens, 11-oxyandrogens derived from the human adrenal glands are recognized as being major androgens. Specifically, 11-oxyandrogens ...
