What happened

‘Gym penis’ is real, says nurse — why it happens and when to see a professional See more of our coverage in your search results.

Why it matters

Add The New York Post on Google It’s the opposite of the “pump.” Summer’s in full swing, and men are looking for any way to get bigger, from a good long gym session to a below-the-belt enhancement.

Common ground

But unlike the increased blood flow gymgoers feel after lifting weights, “gym penis” may leave men with an unwanted post-gym surprise.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.
