Synthetic peptide with an amino acid sequence identical to that of the amino terminal of the alpha subunit of porcine inhibin, and bovine inhibin each increased ovulation rate and the number of follicles of the ewes; bovine inhibin, and not the peptide, increased plasma FSH and LH concentrations. Porcine inhibin had no effect on ovarian activity but markedly elevated plasma FSH and LH. The results suggest that ovulation rate is at least partly determined by intraovarian factors.
