Efficacy of Prolonged GnRH Test in Male Adolescents With Postoperative HH

The Hypogonadotropic Hypogonadism(HH) could be caused by sellar lesions, sellar surgery or sellar radiotherapy. The incidence of HH after sellar surgery was higher in men than in women, and the therapy of HH was insufficient. Gonadotropin-releasing hormone(GnRH) stimulation test is used to evaluate the function of pituitary-gonadal axis. GnRH can be used to diagnose and treat fertility disorders and other endocrine disorders caused by HH. After a single injection of GnRH, the patients with poor response of luteinizing hormone and follicle stimulating hormone need to take extended provocation test, which is conducive to the formulation of the following treatment. GnRH pump can pulse subcutaneous injection of gonadorelin, which can be used as the extended provocation test.
