In the present study, elevated temperatures promoted
PGE2 production, but did not affect PGF2a production in
the cultured ampullary oviductal epithelial cells (Fig. 3).
The body temperature of cows is w38.5 8C, but itincreases under hot conditions. For example, the vaginal
temperature of cows was found to increase to w40.5 8C
under high-temperature conditions
