1. What is Testicular Volume?

Definition: Testicular volume is a measurement of the size of the testicles, calculated using the ellipsoid formula.

Purpose: It's used in medical evaluations to assess testicular development, monitor conditions, and evaluate fertility potential.

2. How Does the Calculator Work?

The calculator uses the ellipsoid formula:

Where:

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

Explanation: The formula approximates the testicle as an ellipsoid shape, which is the standard method for clinical volume estimation.

3. Importance of Testicular Volume

Details: Testicular volume correlates with sperm production and is an important parameter in assessing male reproductive health.

4. Using the Calculator

Tips: Measure the testicle dimensions using ultrasound or orchidometer and enter the values in centimeters. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is normal testicular volume?
A: Average adult testicular volume is 15-25 cm³ per testis, but normal ranges vary by age and individual.

Q2: How accurate is this calculation?
A: The ellipsoid formula provides a good estimate but may differ slightly from actual volume due to natural variations in shape.

Q3: When would testicular volume be measured?
A: Common in fertility evaluations, puberty assessments, and monitoring for conditions like varicocele or testicular atrophy.

Q4: What's the difference between length, width and height?
A: Length is the longest dimension, width is side-to-side, and height is front-to-back measurement.

Q5: Can this calculator be used for pediatric patients?
A: Yes, but normal values differ significantly by age and Tanner stage of development.
