Antral follicle count in cattle: advantages, challenges, and controversy

Antral Follicle Count

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 ...

Antral Follicle Count as Predictor of Ovarian Reserve

Infertility is the inability to conceive following 1 year of unprotected intercourse in cases where the female is ≤35 years of age or following 6 months of unprotected intercourse for women >35 years of age. The female factor infertility is found in 40% of cases, the male in 20% of cases and the both male and female factors in 20% of cases. Female factors can further be divided into tubal (40%)...

Predictors 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 ...

Antral follicle count reliably predicts number of morphologically healthy oocytes and follicles in ovaries of young adult cattle.

Methods to predict numbers of healthy oocytes in the ovaries of young adults could have important diagnostic relevance in family planning and animal agriculture. We have observed that peak antral follicle count (AFC) determined by serial ovarian ultrasonography during follicular waves is very highly reproducible within individual young adult cattle, despite 7-fold variation among animals. Herei...
