Dual-Site Botulinum Toxin Type A Injection for Lifelong Premature Ejaculation

Summary

Premature ejaculation is a common sexual condition that can cause distress for men and their partners. Different treatments are available, but some men do not respond well to standard therapies. This study was designed to evaluate whether injecting botulinum toxin type A into two areas of the penis and surrounding muscles can help delay ejaculation in men with lifelong premature ejaculation. Participants were randomly assigned to receive either botulinum toxin injections or placebo injections. The study evaluated ejaculation time, sexual satisfaction, and quality of life over a follow-up period of six months. Safety and possible side effects were also monitored during the study.
