Sleep apnea testosterone study pulled before starting

NCT ID NCT01850992

First seen Jun 26, 2026 · Last updated Jun 26, 2026

Summary

This study was designed to understand how obstructive sleep apnea (OSA) speeds up the natural drop in testosterone as men age. Researchers planned to use CPAP machines—one real, one placebo—to test hormone changes in men aged 30 to 70 with moderate to severe OSA. However, the study was withdrawn before enrolling any participants, so no data or conclusions are available.
