BACKGROUND The significance of the high variation in numbers of follicles produced during reproductive cycles in humans and cattle is unknown. METHODS We selected beef heifers with high (> or =25) or low (< or =15) numbers of ovarian follicles and determined the association with alterations in FSH and estradiol concentrations, as well as responsiveness to superstimulation and embryo quality. The variation in follicle numbers was also compared with oocyte quality in natural cycles using IVF… Expand
Causes and consequences of the variation in the number of ovarian follicles in cattle.
Inherent capacity of the pituitary gland to produce gonadotropins is not influenced by the number of ovarian follicles > or = 3 mm in diameter in cattle.
Recovery of COCs from ovaries with high follicle numbers enhances in vitro embryo yield in sheep.
