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.

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.
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 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 ...
The risk is further increased by multiple doses of hCG after ovulation and if the procedure results in pregnancy. [2] Using a GnRH agonist instead of hCG for inducing final oocyte maturation and/or release results in an elimination of the risk of ovarian hyperstimulation syndrome, but a slight decrease of the delivery rate of approximately 6%. [3]
Social workers generally have even less training than doctors on drug testing, and little authority to question test results, she said. Investigating the cause of a positive drug test is not ...
This loss is not necessarily a direct effect of the chemotherapeutic agents, but could be due to an increased rate of growth initiation to replace damaged developing follicles. [20] Antral follicle count decreases after three series of chemotherapy, whereas follicle stimulating hormone (FSH) reaches menopausal levels after four series. [21]
