title: The effects of prostaglandin F2alpha on sperm output in boars.
abstract: The effect of prostaglandin F2alpha (PGF2alpha) on the sperm output of six boars was investigated in two studies. Although PGF2alpha did not significantly affect sperm numbers in the ejaculate, a significantly longer (P less than 0.05) ejaculation of the sperm rich fraction occurred following injection of PGF2alpha. In the second study it was found that PGF2alpha produced a 49% increase (P less than 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.
