The tunica albuginea is the primary limiting anatomical factors in determining erect penis size, especially girth.

Here's why:​

  • What is the tunica albuginea?
    It's a tough, fibrous sheath that surrounds the corpora cavernosa, the two sponge-like regions that fill with blood during an erection.
  • Its role in erections:
    During arousal, blood flows into the corpora cavernosa and causes expansion. The tunica albuginea limits how much they can expand—like a balloon with a tough outer wall—which directly affects both the length and girth of the erect penis.
  • Thickness and elasticity vary:
    Some men have a thicker or less elastic tunica, which may limit expansion more than in others. This variation contributes to natural differences in penis size.

Why it's a "limiting" factor:​

  • It determines the maximum pressure the penis can handle during erection.
  • Surgical or trauma-induced modifications (e.g., in Peyronie’s disease treatments) that affect the tunica can result in changes to size—sometimes increasing, but often decreasing it.
  • Stretching devices or techniques aim to induce plastic changes in the tunica over time, but clinical evidence for size increase is mixed and slow.
In short:
✅ Yes, the tunica albuginea is a key structural limiter of penis size—especially during erection.
But it's not the only factor—genetics, hormone levels during puberty, and vascular health also play significant roles.


 
I thought this was gonna be a "too much girth is a bad thing" type of thread. :ogre:
