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%)...

Ovarian Follicle Activity in Yak versus Cattle and Buffalo

A comparison of the ovarian follicular system in cattle, buffalo and yak yields potentially useful information in developing methods for the improvement of reproduction efficiency in yaks. The ovaries in yaks were generally smaller than in both cattle and buffalo. The histological structures of the yak ovaries and follicular system resembled in all aspects those described for cattle and buffalo...

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 ...
