It contains a single oocyte. An ovarian follicle can be initiated to grow and develop, culminating in ovulation of usually a single competent oocyte in humans. Approximately 10 ovarian follicles begin to mature during a normal menstrual cycle and out of these usually one will turn into a dominant ovarian follicle.
An ovarian follicle is a roughly spheroid cellular aggregation set found in the ovaries. It secretes hormones that influence stages of the menstrual cycle. Women begin puberty with aboutfollicles,  each with the potential to release an egg cell ovum at ovulation for fertilization.
The image shows part of a section of the ovary. Follicles consisting of an oocyte surrounded by layers of follicle cells develop in the cortex of the ovary. The arrow bar shows the diameter of one mature or Graafian follicle.

This image shows primordial follicles. Can you identify them, together with the tunica albuginea - the thick collagenous capsule, together with the germinal epithelium that covers it, and the connective tissue in the cortex of the ovary, known as the stroma. Primordial germ cells migrate into the developing gonad early in embryogenesis, and differentiate into oogonia.
The cortex also contains remnants of ovulated follicles and, in mammals, clusters of interstitial cells that, in some species, are glandular. The cortical components are…. He was also important for his studies on the pancreas and on the reproductive organs of mammals.
Related to Graafian follicle: ovarian follicleovulationcorpus luteum. At puberty each ovary has a large number of immature follicles primordial follicleseach of which contains an undeveloped egg cell. About every 28 days between puberty and the onset of menopause, one of the follicles develops to maturity, or ripens, into a graafian follicle or vesicular ovarian follicle. As it ripens, it increases in size.
Graafian follicle A fluid-filled, spherical vesicle in the ovary of a mammal, containing an oocyte attached to its wall, and responsible for oestrogen production in the ovary. A cavity first appears amongst follicle cells surrounding the oocyte, around the end of the period of cytoplasmic growth of the oocyte. In mammals with an oestrus cycleit enlarges during the early part of the cycle, so that follicle cells separate into two layers, one around the oocyte and the other an external layer, until the follicle bursts on to the surface of the ovary, discharging the oocyte ovulation.
