Researchers measure penis size in boys with and without hypospadias
NCT ID NCT03593720
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study measured the size of the glans (head of the penis) and total penile length in 410 boys undergoing urological surgery. Some had hypospadias (a birth defect where the urinary opening is not at the tip), others had other conditions. The goal was to see if glans size differs between the two groups and to track growth patterns by age and ethnicity.
