What is the normal size of egg in folliculometry test?

In a folliculometry test, the normal size of a mature egg, or follicle, typically ranges from 18 to 24 millimeters in diameter. Follicles of this size are considered ready for ovulation. Smaller follicles may be monitored for growth, while those that are significantly larger may indicate potential issues. Regular monitoring is important for assessing ovulation and fertility.
