Sildenafil does not improve erections in healthy young men. However, this study found it may reduce the time needed to recover after ejaculation, suggesting potential use for premature ejaculation.

Area of Science:

Pharmacology
Urology
Sexual Medicine

Background:

Sildenafil is approved for erectile dysfunction (ED).
Anecdotal reports suggest recreational use by young men seeking enhanced sexual performance.
The effects of sildenafil in young men without ED are not well-established.

Purpose of the Study:

To investigate the efficacy of sildenafil in improving erectile quality in young healthy men without ED.
To assess the impact of sildenafil on postejaculatory refractory time in this population.

Main Methods:

Randomized, double-blind, placebo-controlled, single-dose home-use study.
60 healthy men aged 20-40 without ED were enrolled.
Participants received either 25 mg sildenafil or a placebo before intercourse.

Main Results:

No significant difference in reported erection quality improvement between sildenafil and placebo groups (P=0.79).
Sildenafil significantly reduced postejaculatory refractory time compared to placebo (P=0.04).

Conclusions:

Sildenafil does not enhance erections in young men without ED.
Recreational use of sildenafil by healthy young men for erectile enhancement is not supported.
Sildenafil may potentially reduce postorgasmic refractory time, warranting further investigation for premature ejaculation treatment.
