Evidence-based men's health information Emergency? An erection lasting 4+ hours needs urgent care.

About Erenyl

Erenyl exists to give men clear, honest, evidence-based information about erections and erectile dysfunction, without shame and without hype.

How we write our guides

  • We base guides on clinical guidelines (such as the American Urological Association and the NHS), regulatory drug information and peer-reviewed research, and list our sources on every page.
  • We explain uncertainty honestly. Where the evidence is mixed, we say so.
  • We don't promote products with unproven claims, including "natural" erection supplements.
  • We update guides when guidelines or evidence change.

Medical review

We are working with qualified clinicians to review our guides. Reviewed pages will clearly show the reviewer's name and credentials, and the review date.

How Erenyl is funded

Erenyl may earn a commission when readers sign up for some services we link to, such as licensed online clinics. These links will always be labelled. Commissions never decide what we recommend, and we only link to providers that require a proper medical assessment.
