There are three categories when performing an ultrasound to cheek the antral follicle count: Low follicle count (1-3): low ovarian reserve and increased risk of menopause in the next 7 years. Normal follicle count (4-24): Normal follicle amount for women in reproductive age. High follicle count (>=): High risk of hyperandrogenism. It has been ...
Antral follicles are cells early in the process of developing from an oogonium into a mature oocyte. A physician may use a transvaginal ultrasound to visualize and count the number of antral follicles in each of a woman's ovaries in order to determine her ovarian reserve; however AFC is not predictive of embryo quality.

The ovary is generally thought of as an egg bank from which the woman draws during her reproductive life. The human ovary contains a population of primordial follicles.At 18–22 weeks post-conception, the female ovary contains its peak number of follicles (about 300,000 in the average case, but individual peak populations range from 35,000 to 2.5 million [3]). p The size of the initial ...
Transvaginal ultrasonography can be used to determine antral follicle count (AFC). This is an easy-to-perform and noninvasive method (but there may be some discomfort). Several studies show this test to be more accurate than basal FSH testing for older women (< 44 years of age) in predicting IVF outcome. [17]
The rise in FSH levels recruits five to seven tertiary-stage ovarian follicles (this stage follicle is also known as a Graafian follicle or antral follicle) for entry into the menstrual cycle. These follicles, that have been growing for the better part of a year in a process known as folliculogenesis, compete with each other for dominance. [5]
Regarding antral follicle count, with the GnRH antagonist protocol initial follicular recruitment and selection is undertaken by endogenous endocrine factors prior to starting the exogenous hyperstimulation. This results in a smaller number of growing follicles when compared with the standard long GnRH agonist protocol.
Investigators are trying to determine how a woman got past multiple security checkpoints this week at New York’s JFK International Airport and boarded a plane to Paris, apparently hiding in the ...
An ovarian follicle is a roughly spheroid cellular aggregation set found in the ovaries. It secretes hormones that influence stages of the menstrual cycle . At the time of puberty , women have approximately 200,000 to 300,000 follicles, [ 1 ] [ 2 ] each with the potential to release an egg cell (ovum) at ovulation for fertilization . [ 3 ]
