Cialis may ease ED caused by sleep apnea

Sleep apnea may cause erectile dysfunction. Cialis (tadalafil) may ease the problem.
Researchers say that erectile dysfunction (ED) is common condition among men with obstructive sleep apnea (condition when breathing stops several times per night).
New experiments on mice showed decrease in sexual activity within a week of being exposed to brief but chronic bouts of oxygen deprivation during sleep.
The researchers mixed Cialis pills and peanut butter for the male mice. This resulted the mice became more sexually active, but this activity was lower than before the study began.
The researchers tried to find how sleep apnea and ED are linked. There were no problems with testosterone level and with the mice's anatomy, either.
The problem was in lower levels of an enzyme, making nitric oxide during the experiment. Male mice may need more nitric oxide for erections. Cialis settled the problem, but only partially.
The researchers are not sure in recommending Cialis for men with sleep apnea, but they note that treating sleep apnea using a continuous positive airway pressure (CPAP) machine can help with ED, caused by sleep apnea.
