Impairment of the opioidergic control of luteinizing hormone secretion in Turner's syndrome: lack of effect of gonadal steroid therapy.


We studied the activity of endogenous opioid peptides in regulating LH secretion in patients with Turner's syndrome. To do so, we determined the LH secretory response to opiate receptor blockade by naloxone (0.08 mg/kg BW, iv) in 17 patients (age range, 9-23 yr). Eight patients were untreated (3 of whom had had spontaneous menarche), and 9 patients were… (More)
