Story summary
- Researchers documented internal penile triplication after medical students found three penises in a 78-year-old UK donor, a condition occurring in one in five to six million births.
- Dissection measured the penis at 7.7 cm × 2.4 cm and the two others at 3.8 cm × 1.3 cm and 3.7 cm × 1.2 cm, with a urethra winding through the second penis.
- Researchers suggested the anomaly resulted from triplication of the genital tubercle, noting similar cases often have urinary or reproductive complications.
