Summary

The goal of this clinical trial is to learn if Triptorelin test works to early diagnose hypogonadotrophic hypogonadism in adolescents. The main questions it aims to answer are: • Does gonadotropin and gonadal steroids responses to Triptorelin test be useful to diagnose early hypogonadotrophic hypogonadism? Researchers will compare gonadotrophins and gonadal steroids in response to Triptorelin subucutaneos test with clasiccal GnRH infusion to diagnose hypogonadotrophic hypogonadism. Participants will performed two test: * Triptorelin test (subcutanous) * LHRH infusion test

Conditions

• Pubertal Delay
• Hypogonadism, Hypogonadotropic
• Constitutional Delay in Growth and Puberty (CDGP)

Interventions

Type	Name	Description
DIAGNOSTIC_TEST	Triptorelin (GnRH agonists)	1. Triptorelin test. A baseline blood sample will be taken to determine LH, FSH, Estradiol/Testosterone, AMH, and Inhibin B. Then, Triptorelin Acetate 100 ug/m² of body surface area will be administered subcutaneously, maximum dose 0.1 mg (Decapeptyl Daily prefilled syringe of 0.1 mg for subcutaneous administration. Three hours later, a new sample will be taken to determine LH and FSH. The patient may return home and lead a normal life. An appointment will be made the following day to perform the last sample of this test 24 hours after the subcutaneous administration of Triptorelin Acetate, with the determination of LH, FSH, Estradiol/Testosterone, and Inhibin B. 2. GnRH Infusion: This consists of determining LH and FSH in baseline blood samples, 15, 30, 45, 60 and 120 minutes after slow infusion of GnRH. GnRH 0.83 μg/min during the 120 minutes that the study lasts (Luteoliberin 100 μg)
