Question
Does the survival rate of a patient’s sperm change with age or other factors? Is a 65% sperm survival rate normal?
Answer
The normal range for semen volume is 1.5 milliliters to 6.0 milliliters; the color should be milky or grayish-white, while yellow-green may indicate infection or inflammation; the pH level should be between 7.0 and 7.8, as either too low or too high can reduce sperm vitality.
