Right now, there's no conclusive evidence that sildenafil stops premature ejaculation like there is for SSRI medications. However, studies show that sildenafil does have several effects that could be useful in treating PE and improving male sexual performance.

Does sildenafil increase ejaculation time?

In a small 2007 study, researchers found that sildenafil (the active ingredient in Viagra) was linked to an increase in ejaculation time in men affected by premature ejaculation. Another study from 2005 found that men who used sildenafil experienced a small increase in time before ejaculation.

Can Viagra cause delayed ejaculation?

While Viagra isn't linked to delayed ejaculation and generally won't make you last longer in the sense most people think of, it could potentially improve your general sexual performance.
