What is this trial about?

This research is being done to compare the effect of tadalafil with placebo (an inactive substance that looks like the study drug, but should have no effect) on the frequency of recurrent priapism (prolonged erection, unassociated with sexual interest or desire) and the nature of sexual experiences in male patients with sickle cell disease.
