Testicle Size Calculator

Enter your linear dimensions (length and width in centimeters) to estimate volume using the ellipsoid formula.

Understanding Testicular Volume

Testicular volume is an important clinical parameter used by healthcare providers to assess developmental stages, hormonal health, and reproductive function. Normal adult testicular volume typically ranges from 12 to 25 milliliters (mL) per testicle. Dimensions are commonly measured using an orchidometer or medical ultrasound imaging.

The Calculation Formula

This tool uses the standard scientific Prader ellipsoid formula to estimate volume based on length and width measurements:

Volume = Length $\times$ Width $\times$ Width $\times$ 0.523

Clinical Reference Ranges

  • Pre-pubertal: 1 to 3 mL
  • Early Puberty: 4 to 10 mL
  • Adult Normal: 12 to 25 mL
