Development of a bovine model without ovarian follicular waves (waveless) and transient increases in gonadotropin secretion during estrous cycles may lead to new methods to more consistently regulate ovulatory follicle growth thereby improving effici

The causes of the inherently high variation in number of follicles and oocytes in ovaries of mammals are unknown. Evidence suggests that the ovarian reserve (total number of healthy follicles and oocytes in ovaries) can be programmed by events occurr

Anti-Mullerian hormone (AMH) is an ovarian growth factor that plays an important role in regulation of ovarian follicle growth. The objectives of this study were to estimate the genomic heritability of AMH and identify genomic regions associated with

Mammals such as cattle, swine, sheep and humans are born with a highly variable number of ovarian follicles and oocytes in the ovaries that dwindle during ageing and are never replenished. This variation in the ovarian reserve is reflected in the num

Low progesterone concentrations and diminished ovarian reserves (total number of healthy oocytes) during reproductive cycles are linked to infertility in single-ovulating species like cattle. However, the extent and mechanisms whereby the inherently

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 ultr

The bovine dominant follicle (DF) model was used to identify molecular mechanisms potentially involved in initial growth of DF during the low FSH milieu of ovarian follicular waves. Follicular fluid and RNA from granulosa and theca cells were harvest

We hypothesize that granulosa and theca cells from growing dominant follicles, with relatively high intrafollicular concentrations of estradiol, have a greater expression of genes involved in inhibiting apoptosis pathways and lower expression of gene

Intrafollicular concentrations of inhibin A and estradiol vary inversely during development of dominant follicles in cattle. Thus, we hypothesized that inhibin has a negative autocrine or paracrine effect on estradiol production by granulosa cells. T

Antral follicle development in cattle is initially FSH dependent and then LH dependent. The aim of the present study was to determine the effects of oestradiol- and progesterone-induced suppression of FSH and LH on growth and differentiation of first
