Dr. Darius Paduch -- a urologist and male sexual medicine specialist at NewYork-Presbyterian/Weill Cornell Medical Center and director of Sexual Health and Medicine at Weill Cornell Medical College -- said Cialis is currently approved for treatment of erectile dysfunction and benign prostate hypertrophy, enlargement of the prostate.
Researchers conducting a meta-analysis of 17 double-blind, placebo-controlled clinical trials of men with erectile dysfunction concluded about 70 percent of men who used Cialis during sexual activity for 12 weeks were able to ejaculate most of the time and to reach orgasm, compared to 30 percent in the placebo group.
The benefits were seen independent of the level of a man's erectile dysfunction severity.
"There are many men who have, at most, very mild problems achieving an erection but who cannot easily ejaculate," Paduch said in a statement. "Our study shows Cialis works very well for these men with problems ejaculating."
Paduch said as many as 18 percent of men have a normal erection but don't ejaculate, or take a long time to do so. He said it might be more prevalent in the elderly, but it affects men of all ages.
"Many of my patients are young men who want to have children and so they want to solve their issues with ejaculation," Paduch said. "We don't know why this occurs."
The findings are scheduled to be published in the February issue of the British Journal of Urology International.
