Abstract

Secretion of prostaglandins (PG) E2 and PGF by the bovine endometrium and the effects of oxytocin (OT) on these secretions during the estrous cycle were investigated. Bovine uteri were classified into five luteal stages (early I: Days 2-3; early II: Days 5-7; mid-: Days 8-12; late: Days 15-17; regressed: Days 19-21). After l h of pre-incubation, endometrial tissues (20-30 mg) were exposed to 0 or 100 nM OT for 4 h. PGE2 concentration in the medium was higher than that of PGP during the luteal phase, and declined at the regressed luteal stage (P2α secretion reached the highest value at the regressed luteal stage (P2 and PGF secretion at the early luteal stage (P2α secretion at the late and regressed luteal stages (P2 secretion was reduced by OT at the same time (P2 secretion by the bovine endometrium during the estrous cycle and suggest that OT may play a role in modulating the secretion of PGE2 as well as PGP.
