It is a simple technique used by gynecologists for assessing ovarian follicles at regular intervals for tracking and documenting ovulation in women who are trying to get pregnant.
It is a serial ultrasound done mostly by transvaginal route.
Follicles are not oocytes. The follicle is a functional anatomical structure which forms part of the ovary and the egg is the cell that will mature in a microscopic part of the inner wall of a follicle over spontaneous or stimulated ovarian cycle in normal conditions .It also contains other cell types which produce estrogen required for normal development of egg maturation
