Patients With Sleep Apnea and Low Testosterone
Adult male patients between 18-70 years of age with nely diagnosed OSAS documented by all night polysomnography(PSG)
Obstructive Sleep Apnea Syndrome(OSAS) is a highly prevalent disease in the population, affecting at least 4% of males and to a lesser extent females, yet it is currently under diagnosed. OSAS is associated with various disorders including cardiovascular disease, insulin resistance, diabetes mellitus, fatigue and erectile dysfunction. Currently the standard treatment for OSAS is Continuous Positive Airway Pressure(CPAP).
Low testosterone levels are present in some patients with OSAS leading to erectile dysfunction. However, the true prevalence of low testosterone levels and its correlation with sexual health is poorly understood and undefined. Prior data suggest treating these patients with CPAP therapy, usually increases testosterone levels, but unclear if this makes any meaningful difference in patient outcome, that is improvement in libido and sexual function.
There are several postulations to the pathophysiology of low testosterone levels in patients with OSAS. CRP(C-reactive protein), a strong marker of inflammation was shown to be elevated in patients with OSAS. The association between elevated CRP and low testosterone level would support the notion that inflammation plays a primary role in sexual dysfunction in patients with OSAS.
The objective of this study is to identify correlation between low free testosterone levels, sexual dysfunction and Obstructive Sleep Apnea before and after treatment with CPAP. Evaluate the role of CRP and inflammation secondary to OSAS in the pathogenesis of sexual dysfunction.
