Summary

This study tests two injection treatments for men with lifelong premature ejaculation that hasn't improved with standard drugs or therapy. Eighty men will receive either hyaluronic acid into the penis head or botox into a pelvic muscle. Researchers will track changes in ejaculation time, symptom scores, and side effects over one year to see which works better.
