Obstructive Sleep Apnea Also Linked to Decreased Testosterone Levels in Men
Another study suggests that male patients who suffer from obstructive sleep apnea produce lower levels of testosterone, resulting in decreased libido and sexual activity. Researchers at the Technion-Israel Institute of Technology found that nearly half of the subjects who suffered from severe sleep apnea also secreted abnormally low levels of testosterone throughout the night. Previous research had failed to establish a scientific link between decreased libido in men and OSA, because the studies only measured testosterone levels upon awakening. The current study monitored patients through the night.
"Should follow-up studies confirm these findings," said Professor Rafael Luboshitzky, an endocrinologist on the research team, "then therapeutic intervention of sleep apnea could become a recommended remedy for certain forms of male sexual dysfunction." The study appeared in The Journal of Clinical Endocrinology & Metabolism.
