Official title: A double blind, parallel group, placebo controlled study to evaluate the effect of a single oral dose of GSK958108 on ejaculatory latency time (ELT) in male patient suffering from premature ejaculation
Trial description: The purpose of this study is to determine if the administration of GSK958108 can delay ejaculation in patients with primary premature ejaculation as measured by the ejaculatory latency time (ELT) using the masturbation model and sexual visual stimulation, and to evaluate the safety and tolerability of GSK958108 in healthy men with PE
