| Abstract: | The effect of prostaglandin F2α (PGF2α) on the sperm output of six boars was investigated in two studies. Although PGF2α did not significantly affect sperm numbers in the ejaculate, a significantly longer (P < 0.05) ejaculation of the sperm rich fraction occurred following injection of PGF2α. In the second study it was found that PGF2α produced a 49% increase (P < 0.05) in the number of sperm in the sperm rich fraction of the ejaculate. The implications of these results on artificial breeding are discussed. |
