1. What is Testicular Volume Calculation?

Definition: This calculator estimates normal testicular volume in milliliters (1 cm³ = 1 ml).

Purpose: Used in urology to assess testicular size, which can indicate various medical conditions.

2. How Does the Calculator Work?

The calculator uses the ellipsoid formula:

Where:

• \( V \) — Volume in milliliters (ml)
• \( L \) — Length in centimeters (cm)
• \( W \) — Width in centimeters (cm)
• \( H \) — Height in centimeters (cm)

Explanation: The formula approximates the testis as an ellipsoid and calculates its volume.

3. Normal Testicular Volume Range

Details: Normal adult testicular volume typically ranges between 10-20 ml per testis.

4. Using the Calculator

Tips: Measure length, width and height using ultrasound or orchidometer. Enter values in centimeters.

5. Frequently Asked Questions (FAQ)

Q1: Why measure testicular volume?
A: Volume assessment helps diagnose conditions like hypogonadism, varicocele, or testicular tumors.

Q2: How accurate is this calculation?
A: It's an approximation. Ultrasound provides more precise measurements than physical examination.

Q3: What's considered abnormal volume?
A: Volumes <10 ml may indicate atrophy, while >25 ml may suggest pathology.

Q4: Does age affect normal volume?
A: Yes, testicular volume increases during puberty and may decrease with aging.

Q5: Can I use this for pediatric patients?
A: Yes, but normal ranges differ by age and Tanner stage.
