Effects of Andriol Testocaps in Symptomatic Late-Onset Hypogonadism (43203)

Phase 2

Completed

• Conditions: Androgens; Hypogonadism
• Interventions: Drug: Placebo; Drug: Oral testosterone undecanoate (Andriol)

• Registration Number: NCT00434824
• Lead Sponsor: Merck Sharp & Dohme LLC

Brief Summary

In this study we have evaluated the effects of three different doses of oral testosterone undecanoate in aging men presenting with a combination of symptoms suggestive of hypogonadism and low blood levels of the male hormone testosterone.

Specifically, we have studied the effects on:

* symptoms suggestive of low testosterone levels

* blood testosterone and other hormone levels

* bone mass

* muscle mass and fat mass

* muscle strength

* prostate

* lipids, hematocrit
