Brief Summary

In this prospective open clinical study, Pubertal Replacement in Boys Study (PRIBS), boys 14-16 years with delayed puberty in terms of slow pubertal progression, were randomized to SoC treatment with TE: Testostoviron depot® 75 mg intramuscularly (i.m) / month (6 injections), or low dose TU: Nebido® 250mg i.m. / 3 months (2 injections). Our goal was to implement a study similar to clinical routine.
