What happened

Women aren’t the only ones getting boob jobs.

Why it matters

While gynecomastia, or enlarged male breast tissue, often resolves on its own, a growing number of men are turning to plastic surgery to achieve a flatter, more contoured chest.

Common ground

The condition most commonly appears during natural hormonal shifts like puberty, but other triggers can play a role as well.

Perspective signals

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