Prevalence of sleep apnea in men with erectile dysfunction.

Sleep studies were performed on 1,025 patients complaining of erectile dysfunction. In addition to standard measures of sleep stage and nocturnal penile tumescence, respiratory activity was evaluated. The number of episodes of sleep apnea per hour (Apnea Index--AI) was calculated for each patient. The overall prevalence of sleep apnea activity in this sample was: 43.8 percent with AI greater than or equal to 5; 27.9 percent with AI greater than or equal to 10; and 19.6 percent with AI greater than or equal to 15. These results confirm that sleep apnea activity is common in men with erectile dysfunction. This high prevalence also indicates that further study is needed to elucidate pathophysiology of erectile failure in men with sleep apnea.

Uterine activity during sleep.

REM-related increases in uterine activity were found in 10 healthy young adult volunteer subjects. Contraction baseline pressures were elevated compared with NREM sleep, stage 2 sleep, stages 3 and 4 slow wave sleep (SWS), and stage 0. Contraction amplitudes during REM sleep were greater than those during SWS and stage 0, while contraction rates differed only between REM sleep and SWS. The results strongly indicated a cycle of genital activity in women that parallels the penile erection cycle in men. The implications of this finding and suggestions for future research are discussed.
