Congenital Adrenal Hyperplasia (CAH) includes a group of disorders, in which the cortisol production by
adrenals is lowered. There are several different forms of CAH, each related to one of the enzymes
necessary to transform precursors to cortisol. When one of these enzymes is deficient, this leads to a
hyper function and increased size (hyperplasia) of the adrenals.
Among the various forms of CAH, the 21-hydroxylase deficiency is by far the most frequent, representing
more than 90 of all cases. 21-hydroxylase deficiency results in high level of circulating 17-
hydroxyprogesterone. Various mut

Progesterone is a C-21 female sex steroid hormone with a variety of physiological effects. In the follicular phase of the menstrual cycle, progesterone is produced in low levels. It increases to the LH peak and then sharply rises 3 to 4 days later to higher levels, remaining elevated through the 10th to 12th days after the LH peak. Next there is a sharp decline to the low levels of the follicular phase. Progesterone is responsible for the induction of the cyclic changes in the endometrium of the uterus allowing implantation and successful growth of the fertilized ovum and maintenance of pregna
