Objectives of this study were to determine if concentrations of steroids, insulin-like growth factor -I (IGF-I), and IGF binding proteins (IGFBP) in follicular fluid and numbers of LH and IGF-I receptors change during growth of the dominant follicle.
Insulin-like growth factor-binding protein-2 and -3: their biological effects in bovine thecal cells

This study was aimed at testing the hypothesis that the insulin-like growth factor-binding proteins (IGFBP)-2 and -3 can modulate the hormone-dependent differentiation of thecal cells in vitro. Thecal cells from large (or = 8 mm) follicles were colle

Ovarian function of nutritionally induced anoestrus cows was evaluated in vivo (Expt 1) and in vitro (Expt 2). In Expt 1, 32 nutritionally induced anoestrous beef cows were divided into four treatment groups receiving: (1) saline infusions at one pul
