The effects of prostaglandin F2alpha on sperm output in boars.
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.
