What Is Follicular Study Test?

Follicular study is charting the follicular growth after the menstruation. Follicular monitoring is completed at ovulation. Usually follicles start growing 3 to 5 days after menstruation. Slowly they grow with rise of hormones to attain a size of 16mm to 20mm. At this stage the egg is mature enough for fertilisation. After release of egg, that is after ovulation the follicle start releasing progesterone hormone. Thus it turns into a supporting organ for pregnancy.
