A 17-year-old girl seeks your advice about 3 months of amenorrhea. Since menarche at age 12, her menstrual periods have occasionally been regular, but she has had several episodes of amenorrhea, some lasting up to 3 months. In the past, medroxyprogesterone (10 mg/d for 5 days) had always resulted in menstrual bleeding. A similar course of this medication completed last week has so far not resulted in menstruation. Physical examination shows an adolescent female who stands 168 cm (66 in) and weighs 80 kg (176 lb). Her physical examination is also remarkable for some breast engorgement and tenderness, but no galactorrhea is seen. Pelvic examination, although limited by her weight, appears normal.
Her mother works in a clinical chemistry laboratory and is able to give you the following laboratory studies done on blood drawn 5 days ago: serum prolactin, 38.2 ng/mL; serum T4, 12.4 µg/dL; resin T3, 23.8% uptake.
What is the most appropriate first step for you to take?
(A) Order magnetic resonance imaging of the pituitary with gadolinium.
(B) Prescribe bromocriptine, 2.5 mg at bedtime.
(C) Order measurement of her serum thyrotropin (TSH) level.
(D) Order measurement of her serum beta–human chorionic gonadotropin (hCG) level.
(E) Order measurement of her serum follicle-stimulating hormone (FSH) level.
