Which agent is commonly used as a topical desensitizing treatment for premature ejaculation?

• A. Lidocaine
• B. Sertraline
• C. Sildenafil
• D. Tramadol

Answer: (A)

Reducing penile sensitivity with a topical local anesthetic is a common approach to treating premature ejaculation. Lidocaine, used in creams or gels applied to the glans before sex, works by blocking sodium channels in nerve endings, which dampens sensory input from the penis. With less sensation, the ejaculatory reflex takes longer to trigger, helping to increase the time to ejaculation. This approach is different from systemic options. Sertraline is an oral SSRI that can delay ejaculation through central nervous system effects, but it isn’t a topical desensitizer. Sildenafil improves erectile function, not ejaculation control, and tramadol is an opioid analgesic with no typical role as a topical desensitizer for ejaculation. So lidocaine is the best choice here because its role as a topical anesthetic directly decreases penile sensitivity to help delay ejaculation.
