Mechanisms of Control of the Intratesticular Hormonal Milieu in Man

University of Washington·interventional·Posted Oct 6, 2010·Updated Mar 31, 2014

In Brief

A Phase 2 clinical trial evaluating Acyline, Testosterone gel, and 5 other interventions for Healthy Males. Completed, enrolled 46 participants across 1 site.

Detailed Summary

The purpose of this research study is to determine how much male hormone, testosterone, is necessary to maintain sperm production in the testis. This knowledge will be used to help in the development of a safe male hormonal contraception. Specific Aims: 1. to determine if ketoconazole plus acyline will suppress intratesticular testosterone(ITT) to a greater degree than acyline alone. 2. to determine if dutasteride plus acyline will suppress intratesticular dihydrotestosterone (IT-DHT) to a greater degree than acyline alone. 3. to determine if anastrazole plus acyline will suppress intratesticular estradiol(IT-E2) to a greater degree than acyline alone.
