In this study, we investigated the cut-off values of the GnRH (gonadorelin) stimulation test to discriminate between IHH and CDP by estimating the values of LH and FSH at various time points after GnRH stimulation, and evaluating the sensitivity and specificity of the test.

The measurement of hormone reserve and regulation by dynamic tests [L-arginine test (300 mL 10% L-arginine IV within 30 min: normal increase of growth hormone), thyrotropin-releasing hormone test, gonadotropin-releasing hormone test (Gonadorelin; Relefact LH-RH 0.100 mg; 1 mL as bolus IV; normal increase of follicle-stimulating hormone and luteinizing hormone), adrenocorticotropic hormone (ACTH) test (121 pg corticorelin-trifluoroacetate IV; normal increase of cortisol, testosterone, dehydroepiandrosterone-S, 17 [alpha]-hydroxyprogesterone, and androstendion) (11)] revealed normal results, which ruled out the possibility of a disturbance of the hypothalamic-pituitary--target system.
This test involves intravenous infusion of 30 U of GnRH gonadorelin and measurement of gonadotropins at 0, 20, 40, and 60 minutes after infusion.
