Antral Follicle Count
ثبت نشده
چکیده
The number of antral follicles (a stage of folliculogenesis) determinates the quantity of oocytes potentially available for ovulation. It is one of the characteristics used to specify so called ovarian reserve which represents important factor to predict the result of IVF cycle, among other things. AFC can be set by usage of transvaginal ultrasonography (a sonography that applies an ultrasound transducer in the vagina to visualize organs within the pelvic cavity). AFC is reflecting quite accurately the pool of recruitable follicles in ovaries affected by follicle-stimulating hormone (FSH) and correlates with ovarian response in IVF programmes. AFC also correlates with menopausal transition. To comprehend the importance of antral follicle count, it needs to be explained at least briefly the definition of antral follicle itself.

CONTEXT Increased Anti-Mullerian Hormone in polycystic ovary syndrome, may be due to overactive follicles rather than reflect antral follicle count. OBJECTIVE Does Anti-Mullerian Hormone reflect antral follicle count similarly in women with or without polycystic ovary syndrome or polycystic ovarian morphology?

متن کاملPredictors of antral follicle count during the reproductive years.
BACKGROUND We sought to identify indicators of antral follicle count which would be serviceable to clinicians seeking to estimate the number of ovarian follicles without relying on sonographic counts. METHODS We examined the relations of chronological age and four potential indicators of ovarian age-ovarian volume, FSH, dimeric inhibin B and estradiol-to antral follicle count in 176 recently ...
متن کاملImpaired ovarian blood flow and reduced antral follicle count following laparoscopic salpingectomy for ectopic pregnancy.
BACKGROUND Whether salpingectomy affects ovarian function is controversial. In this study, ovarian function was assessed by antral follicle count, ovarian volume and ovarian stromal blood flow measured by three-dimensional (3D) power Doppler ultrasonography. The objectives of the study were to compare the ovarian function of the operated side with the non-operated side after unilateral salpinge...

BACKGROUND Several studies have reported a correlation between antral follicle count by conventional 2D transvaginal sonography and serum anti-Müllerian hormone levels. However, few studies have investigated the effectiveness of 3D SonoAVC transvaginal ultrasound technology, particularly in infertile women. Therefore, this study aims to evaluate the usefulness of three-dimensional (3D) SonoAVC ...
