1. What is Normal Ovary Volume Calculator?

Definition: This calculator estimates the volume of an ovary using ellipsoid formula based on its three-dimensional measurements.

Purpose: It helps medical professionals assess ovary size which is important for evaluating reproductive health and detecting abnormalities.

2. How Does the Calculator Work?

The calculator uses the formula for ellipsoid volume:

\[ V = \frac{\pi}{6} \times L \times W \times H \]

Where:

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

Explanation: The formula calculates the volume of an ellipsoid, which approximates the shape of a normal ovary.

3. Importance of Ovary Volume Calculation

Details: Normal ovary volume ranges between 5-15 cm³ in premenopausal women. Volume changes can indicate conditions like PCOS, ovarian cysts, or menopause.

4. Using the Calculator

Tips: Enter the three orthogonal measurements (length, width, height) obtained from ultrasound imaging. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is the normal range for ovary volume?
A: Typically 5-15 cm³ in reproductive-age women, varies with age and menstrual cycle phase.

Q2: Why use the ellipsoid formula?
A: It provides a good approximation of ovary volume which is often ellipsoid in shape.

Q3: How accurate is this calculation?
A: It's a close estimate; actual volume may vary slightly depending on ovary shape.

Q4: When would ovary volume be abnormal?
A: Increased volume may indicate PCOS (typically >10 cm³) or cysts; decreased volume may suggest menopause.

Q5: Should both ovaries be measured?
A: Yes, both ovaries should be measured as they may differ in size.
