About this trial

This is an interventional treatment trial for Hypogonadotrophic Hypogonadism focused on measuring Hypogonadism, Endothelial dysfunction, Inflammation, Insulin resistance, Testosterone replacement therapy

Eligibility Criteria

18 Years - 26 Years (Adult)MaleDoes not accept healthy volunteers

Inclusion Criteria:

  • Men
  • Treatment naive
  • Hypogonadotrophic hypogonadism

Exclusion Criteria:

  • Previous history of androgen replacement

Daily testosterone transdermal gel

Injectable Testosterone esters

Arm Description

Testosteron 250mg injection per 3-4 weeks for 6 months

Outcomes

Primary Outcome Measures

The alterations in the measures for endothelial functions
The alterations in Endothelial functions are determined by measuring plazma ADMA levels, as a surrogate. ADMA measurement is pereformed by ELISA kit (Immundiagnotik, Bensheim, Germany)(Catalog Number 7828) with a minimal detection limit of 0.05µmol/L.
The alterations in the measures of insulin resistance
The alterations in insulin sensitivity are estimated by using the HOMA index by the formula, HOMA-IR = (insulin x glucose)/405.
The alterations in the measures of inflammation
The alterations in the measures of inflammation are determined by measuring Human Pentraxin-3 levels. ELISA kiti /R&D Systems, Inc. Minneapolis, MN, ABD) (Catalog number DPTX30) with a minimal detection limit of 0.025ng/ml, intraassay CV of 3.8-4.4%, and interassay CV of 4.1-6.1% was used.
