Official title
Hyaluronic Acid Versus Botox Injection in Treatment of Life Long Drug Resistant Premature Ejaculation. Which is Better? Randomized Study
Overview
Premature ejaculation (PE) is one of the most common male sexual dysfunctions, often resistant to conventional pharmacological and behavioral treatments. This randomized clinical trial aims to compare the safety and efficacy of two minimally invasive treatment options - hyaluronic acid (HA) injection into the glans penis versus botulinum toxin type A injection into the bulbospongiosus muscle - in men with lifelong drug-resistant premature ejaculation. Eighty participants will be randomly assigned in a 1:1 ratio to receive either HA or botulinum toxin injection. The primary outcome is change in intravaginal ejaculatory latency time (IELT). Secondary outcomes include changes in Premature Ejaculation Diagnostic Tool (PEDT), Arabic Index of Premature Ejaculation (AIPE) scores, Premature Ejaculation Profile (PEP), patient satisfaction, and treatment-related adverse events during a 12-month follow-up period.
Interventions
- Drug Botulinum toxin type A
Botulinum toxin type A will be reconstituted by diluting 100 units in 10 milliliters of sterile normal saline. Using ultrasound guidance, 5 milliliters will be injected into each side of the bulbospongiosus muscle through a single puncture site while the patient is in the lithotomy position. The aim is to achieve even distribution of the toxin within the muscle fibers to reduce muscular contractions associated with ejaculation. - Drug Hyaluronic acid
Two milliliters of 3.5 percent micronized hyaluronic acid gel will be injected into the dermis of the glans penis using the Fanning Technique. The injection will be performed through a single puncture site with a 27-gauge needle, advancing from the tip of the glans toward the coronal sulcus to distribute the gel evenly. Topical anesthetic cream containing lidocaine and prilocaine will be applied for 30 minutes before the procedure.
Primary outcome measures
- Change in intravaginal ejaculatory latency time [Time frame: Baseline, 1 month, 3 months, 6 months, and 12 months after intervention]
Secondary outcome measures (4)
- Change in Premature Ejaculation Diagnostic Tool (PEDT) score [Time frame: Baseline, 1 month, 3 months, 6 months, and 12 months after intervention]
- Change in Arabic Index of Premature Ejaculation (AIPE) score [Time frame: Baseline, 1 month, 3 months, 6 months, and 12 months after intervention]
- Change in Premature Ejaculation Profile (PEP) score [Time frame: Baseline, 1 month, 3 months, 6 months, and 12 months after intervention]
- Patient satisfaction score [Time frame: 1 month, 3 months, 6 months, and 12 months after intervention]
