What this trial studies

This investigation assesses the effectiveness of two types of NRL condoms containing benzocaine in prolonging time to ejaculation compared to a standard NRL condom without benzocaine. Healthy adult men who feel they ejaculate too quickly during vaginal sex will participate in the study. Participants will use either a condom with 5% benzocaine, one with 3% benzocaine, or a control condom, and their experiences will be evaluated. The study aims to determine if these benzocaine-infused condoms can help improve sexual performance.

Who should consider this trial

Good fit: Ideal candidates are healthy adult men aged 18 to 60 who are sexually active and in a stable, monogamous relationship.

Not a fit: Patients with pregnant or breastfeeding partners, or those with a history of substance abuse, may not benefit from this study.

Why it matters

Potential benefit: If successful, this could provide a non-invasive option for men experiencing premature ejaculation, enhancing their sexual experience.

How similar studies have performed: While similar approaches have been explored, this specific use of benzocaine in condoms is relatively novel and has not been extensively tested.
