Episode notes
Penis Structure Drives Erection And Sensation
- The penis contains erectile tissues (corpora cavernosa and corpus spongiosum) that fill with blood to cause an erection.
- The glans, corona, and frenulum have high nerve density and play central roles in sensation and ejaculation.
Frenulum's Role In Sensation And Ejaculation
- The frenulum connects the foreskin to the shaft and contains many nerve endings that influence sensation.
- Shorter frenulums may increase tension during erection and could be linked to premature ejaculation in small studies.
Monthly Testicular Self-Check
- Examine your testicles monthly to learn their normal feel and detect abnormalities early.
- If you find something unusual, get an ultrasound and consult your doctor promptly because testicular cancer is highly treatable.
