Argentina48 participantsStarted 2022-08-01

Plain-language 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

Inclusion Criteria: * Female patients presenting with Tanner breast stage 1 or 2 at age ≥ 13 years or male patients with testicular volume \< 5 cc at age ≥ 13.5 years, or who have had pubertal changes but have arrested pubertal development for a period of one year. Female patients presenting with primary amenorrhea (absence of menarche at age 15) \> 4 years after the onset of puberty or secondary amenorrhea \> 6 months with no other apparent cause (having ruled out other hormonal disorders such as premature ovarian failure, hypothyroidism, hyperprolactinemia, non-classical congenital adrenal hyperplasia, and polycystic ovary syndrome) may also be included. Patients with or without olfactory disorders, and with or without a previous diagnosis of other pituitary deficiencies will be included. In the case of a history of CNS tumor pathology, inclusion in this study will be considered only if the patient is in remission from the oncological disease and if they have received CNS radiotherapy, at least one year has passed since the beginning of the treatment. If patients have started HRT, they may be included as long as they stop taking it for two half-lives of the compound used, therefore a 2-month free period is necessary for oral tablets or patches and 3 months for monthly testosterone injections or 7 months for testosterone undecanoate injections. Exclusion Criteria: * Patients will be excluded if, due to previous history or relevant clinical history or initial lab…

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
