title: Normal gestation and diminished androgen responsiveness in an untreated patient with 21-hydroxylase deficiency.
abstract: A 22-year-old woman with 21-hydroxylase deficiency but minimal clinical evidence of androgenization was studied. She had conceived twice and had borne a normal male infant without therapy of any kind. The diagnosis of 21-hydroxylase deficiency was substantiated by the findings of 17-ketosteroid and pregnanetriol excretions of 18.1 and 8.1 mg/24 hours, respectively. Adequate basal compensation was indicated by a fasting plasma cortisol of 17.5 mug/dl. Plasma ACTH (207 pg/ml), testosterone (216 ng/dl) delta4-androstenedione (649 mg/dl), progesterone (249 ng/dl) and 17alpha-hydroxyprogesterone (4820 ng/dl) were all significantly elevated.
