What does 14mm left ovarian follicle mean?

A 14mm left ovarian follicle means that there is a follicle, which is a small sac containing an immature egg, on the left ovary that measures 14 millimeters in diameter. Follicles grow during the menstrual cycle in preparation for the possible release of an egg during ovulation. Typically, ovulation occurs when a follicle reaches around 18-25mm in diameter. It is important to note that the size and development of ovarian follicles can vary from person to person and cycle to cycle. Monitoring follicle development is often done using ultrasound imaging during fertility treatments or when trying to understand the menstrual cycle.
