Clinical Trials

Clinical trials showed Xialla to be effective in treating moderate to severe ED when used alone and in combination with drug or injection therapy.

Xialla’s effectiveness was demonstrated in two peer-reviewed clinical trials. Both were featured in the Journal of Sexual Medicine, the world’s premier, authoritative publication in the field of sexual function and dysfunction.

Research findings

In the first study, Xialla—referred to as a “silicone loop occlusive device”—offered significant erectile function and sexual function benefit to 66% of patients. The second study presented similar findings, with 14 out of 21 post-radical prostatectomy patients experiencing significant benefits. The researchers concluded that Xialla offers “unique properties of fixation and force vector application” in comparison to other penis rings or occlusion devices. Feedback from sexual partners also indicated that Xialla is less obtrusive and more comfortable than other devices.
