Sometimes the maturing follicle ( dominant follicle ) grows at a good pace but fails to ovulate, and later becomes a cyst filled with fluid only.Follicular monitoring is the process of tracking growth of the ovarian follicles to identify maturation status of eggs. This is done by serial ultrasound imaging. Ovarian follicles are the basic units of female fertility. Each of the follicles contains a single egg. These structures are periodically initiated to grow and develop, leading to release of a single mature egg in female. Apart from nurturing the egg, follicles also contain cells which produce hormones in you. Follicular monitoring tells us about the time of follicular growth and release of egg. This helps in administering medications in time. Follicular monitoring is an important part of IUI and IVF program.
