摘要

PGF2alpha in semen has been shown to induce uterine contractions, thereby, facilitating sperm transport during fertilization. Previously, we demonstrated that extended boar semen used in artificial insemination does not increase myometrial contractility, but PGF2alpha supplementation did. In this study, we determined the concentrations of endogenous PGF2alpha in pre-sperm and sperm-rich fractions of the boar ejaculate and examined whether changes in the concentration of exogenous PGF2alpha occurred when added to extended boar semen after 72-h incubation at a 17 degrees C storage temperature. Concentrations of endogenous PGF2alpha (n = 10 boars) in pre-sperm and sperm-rich fractions were 69.6 +/- 7.6 and 58.9 +/- 4.4 pg/ml, respectively. No differences were observed in the concentrations of exogenous PGF2alpha in the extended boar semen at 0 h (59.3 +/- 3.3 microg/ml) and after a 72-h incubation period (52.0 +/- 2.1 microg/ml). These results suggest that the concentration of endogenous PGF2alpha in boarsemen used for artificial insemination is < 100 pg/ml. The concentration of exogenous PGF2alpha in the extended boar semen did not differ after 72 h, which indicates that it is not metabolized during this period of time.
