Qué hace esta calculadora
Provides an ellipsoid volume estimate for ovarian and testicular measurements.
Choose the organ and enter length, width, and height in the displayed units.
Antes del cálculo
- Measure three orthogonal dimensions for each side on the same examination and select the correct organ.
- Keep units, planes, and the organ-specific coefficient consistent between sides.
Alcance clínico
Use this tool to estimate right and left ovarian or testicular volume from three orthogonal ultrasound dimensions. It is a geometric measurement aid, not a diagnostic classification.
Aplicabilidad y exclusiones
- Do not combine dimensions from different planes or examinations.
- Irregular masses, postoperative anatomy, large cysts, and distorted organs may not be represented well by an ellipsoid approximation.
Método y lógica de cálculo
Select the organ and enter three perpendicular dimensions for each side. The calculator applies its organ-specific ellipsoid coefficient and returns volume in milliliters.
Estimated volume = length × width × height × organ-specific coefficientTabla de interpretación
| Output | Interpretation |
|---|---|
| Right volume | Geometric estimate for the right gonad |
| Left volume | Geometric estimate for the left gonad |
| Side-to-side difference | Describe with age, pubertal status, symptoms, and morphology |
Errores frecuentes
- Applying an ellipsoid formula to a markedly irregular, distorted, cyst-replaced, or postoperative organ.
- Interpreting volume without age, pubertal or menopausal status, symptoms, and morphology.
The output is an organ-specific geometric estimate, not a diagnosis or a universal normal-range assessment.
Ejemplo práctico
Caso: Fictional example: three perpendicular dimensions are recorded for each testis on the same ultrasound examination.
Cálculo: Select testis, enter dimensions in the displayed units, and calculate both sides with the same method.
Interpretación: Report the estimated volumes with the formula or coefficient used and correlate any asymmetry with morphology and clinical context.

Preguntas sobre esta calculadora
Is an estimated volume a diagnosis?
No. Normal ranges vary with organ, age, pubertal or menopausal status, and technique.
Why should the same technique be used on both sides?
Using the same planes, units, and coefficient reduces artificial side-to-side differences.
