1. What is Testicular Volume Calculator?

Definition: This calculator estimates normal testicular volume using the ellipsoid formula based on length, width, and height measurements.

Purpose: It helps medical professionals assess testicular size, which is important for evaluating sexual development and detecting abnormalities.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( V \) — Volume (cubic centimeters)
• \( L \) — Length (centimeters)
• \( W \) — Width (centimeters)
• \( H \) — Height (centimeters)

Explanation: The formula approximates the testicle as an ellipsoid, with π/6 (≈0.52) being the ellipsoid correction factor.

3. Importance of Testicular Volume

Details: Normal adult testicular volume ranges from 10-20 cm³. Volume assessment helps diagnose conditions like hypogonadism, varicocele, or tumors.

4. Using the Calculator

Tips: Measure length, width, and height in centimeters using ultrasound or orchidometer. Enter all three dimensions for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What's the normal range for testicular volume?
A: Typically 10-20 cm³ in adults, 1-2 cm³ in infants, and 3-8 cm³ in prepubertal children.

Q2: How accurate is this calculation?
A: The ellipsoid formula is about 80-90% accurate compared to water displacement methods.

Q3: When should I be concerned about testicular volume?
A: If volume is <12 cm³ in adults, or if there's significant asymmetry (>2 cm³ difference).

Q4: Can I use this for pediatric patients?
A: Yes, but normal ranges differ by age and Tanner stage of development.

Q5: What's the clinical significance of testicular volume?
A: Correlates with sperm production, testosterone levels, and overall reproductive health.
