Botox for Premature Ejaculation

Botulinum toxin (Botox) has been investigated as a treatment for premature ejaculation (PE), mainly by injecting it into muscles involved in ejaculation, such as the bulbospongiosus muscle. The theory is that temporarily reducing muscle contractions may delay ejaculation.

However, Botox is not currently a standard or established treatment for PE. The AUA/SMSNA guideline notes that clinical development of botulinum toxin for PE was discontinued after interim analysis showed insufficient efficacy, and the guideline does not recommend it as standard care.

Current guideline-supported options include:

• Dapoxetine, where available
• Topical lidocaine/prilocaine anesthetics
• SSRIs or clomipramine in appropriate cases
• Behavioral/psychosexual techniques, often combined with medication
• Treating an underlying problem such as erectile dysfunction or prostatitis when present

The 2026 EAU guideline update also continues to emphasize evidence-based pharmacological and psychosexual approaches; botulinum-toxin injections remain an area requiring more evidence rather than an established Premature Ejaculation treatment.
