Xialla was evaluated in two clinical studies, both presented at the World Meeting on Sexual Medicine and published in the Journal of Sexual Medicine. They evaluated Xialla in men with moderate to severe erectile dysfunction, including men using it on its own and men using it with oral medication or injection therapy. The question in each study was whether holding the ring at the base — so venous outflow stays reduced during sex — improved erectile function where a conventional ring, or the existing treatment alone, had not.
Men with moderate to severe ED had improved erectile function. That is 66%. The men had different causes of ED. Some used Xialla alone, and some used it with medication or injections.
