1. What is a Testicular Volume Calculator?

Definition: This calculator estimates testicular volume using the ellipsoid formula, adjusted for age norms.

Purpose: It helps medical professionals and researchers assess testicular development and detect abnormalities.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( V \) — Volume of testis (cm³)
• \( L \) — Length (cm)
• \( W \) — Width (cm)
• \( H \) — Height (cm)

Explanation: The formula approximates the testis as an ellipsoid. The result can be compared to age-specific normative values.

3. Importance of Testicular Volume Measurement

Details: Testicular volume is an important parameter for assessing puberty development, fertility potential, and detecting conditions like varicocele or hypogonadism.

4. Using the Calculator

Tips: Measure length, width, and height in centimeters using ultrasound or orchidometer. Enter the patient's age for age-adjusted interpretation.

5. Frequently Asked Questions (FAQ)

Q1: What are normal testicular volumes by age?
A: Newborns: ~1 cm³; Prepubertal: 1-2 cm³; Puberty: rapid increase; Adults: 15-25 cm³ per testis.

Q2: How accurate is the ellipsoid formula?
A: It's a good approximation, though ultrasound provides more precise measurements than physical exam.

Q3: When should I be concerned about testicular volume?
A: Significant asymmetry (>2 cm³ difference) or volumes outside age-expected ranges warrant evaluation.

Q4: How does age affect the interpretation?
A: Volume norms vary dramatically by age, especially during puberty. Always consider age in interpretation.

Q5: Can this calculator diagnose conditions?
A: No, it only provides volume estimation. Clinical correlation and additional tests are needed for diagnosis.
