An antral or secondary follicle, also known as Graafian follicle and tertiary follicle, is an ovarian follicle during a certain latter stage of folliculogenesis. Definitions differ in where the shift into an antral follicle occurs in the staging of folliculogenesis, with some stating that it occurs when entering the secondary stage, [ 1 ] and ...
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. [12] A higher number of antral follicles indicates a higher likelihood of pregnancy by IVF.
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]
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.
A clomiphene challenge test is a variation on this approach. [9] Another approach is to examine the ovaries by gynecologic ultrasonography and to determine their size as ovaries depleted of egg cells tend to be smaller [10] and to examine the number of antral follicles visible by sonography. [11]
Device for both vaginal ultrasonography and abdominal ultrasonography Transvaginal ultrasonography to check the location of an intrauterine device (IUD). The examination can be performed by transabdominal ultrasonography, generally with a full bladder which acts as an acoustic window to achieve better visualization of pelvis organs, or by transvaginal ultrasonography with a specifically ...
The most accurate ultrasound test can detect 96% of ovarian cancers in postmenopausal women, new research suggests. The findings indicate that the test should replace the current standard of care ...
Anti-Müllerian hormone (AMH) and antral follicle count (AFC) are the primary markers used to evaluate the remaining oocyte pool. AMH, secreted by granulosa cells of preantral and small antral follicles, offers a cycle-independent, minimally invasive method for predicting ovarian response in assisted reproductive technology (ART).
