The ovarian follicular reserve has been linked to fertility in cattle. Young adult cattle with low vs. high numbers of antral follicles ≥ 3 mm in diameter in follicular waves also have fewer preantral follicles and decreased fertility. This undersc

In cattle and other species in which the pool of resting, primordial follicles is formed during fetal life, little is known about the regulation of the early stages of ovarian follicular development. We used histological morphometry and a combination

The mechanisms controlling the initiation and early stages of follicular growth are poorly understood. Our laboratory developed a serum-free culture system that supports spontaneous and wholesale activation of primordial follicles in pieces of cortex

The first critical transition in follicular development, the activation of primordial follicles to leave the pool of resting follicles and begin growth, is poorly understood, but it appears that the balance between inhibitory and stimulatory factors

In mice deficient in progesterone receptor (PR), follicles of ovulatory size develop but fail to ovulate, providing evidence for an essential role for progesterone and PR in ovulation in mice. However, little is known about the expression and regulat

The activation of primordial follicles appears to be regulated by a myriad of factors, and the current evidence suggests that whether an individual follicle stays in the resting pool or initiates growth may depend on the balance of stimulatory and in

This study examined the onset of puberty, follicular dynamics, reproductive hormone profiles, and ability to maintain pregnancy in cloned heifers produced by somatic cell nuclear transfer. Four adult somatic cell-cloned heifers, derived from a 13-yr-

The development of ovarian follicles is a protracted process. Even in rodents, it is estimated to take about 8 weeks for development from the primordial to the preovulatory stage (Hirshfield 1991), and estimates for larger mammals like humans and cat

A critical transition in ovarian follicular development is the selection of a dominant follicle, capable of ovulating, from a cohort of synchronously growing antral follicles. However, little is known about mechanisms and factors that regulate the se

Low molecular weight insulin-like growth factor binding proteins (IGFBPs), particularly IGFBP-4, are believed to inhibit the actions of insulin-like growth factors (IGFs). We showed previously that ovarian follicular dominance in cattle is associated
