Effect of hCG and eCG Treatments on Prostaglandins Synthesis in the Porcine Oviduct

Contents The oviduct plays a crucial role in fertilization, gamete maturation and embryo transport. Prostaglandins are some of the main factors determining its roles. The present study investigated the influence of oestrus synchronization and superovulation on prostaglandins synthesis in the porcine oviduct. Mature cross-bred gilts after exhibiting oestrous cycles were divided into four groups: I, cyclic; II, inseminated; III, synchronized and inseminated; and IV, superovulated and inseminated. Oviducts were collected on the third day of the oestrous cycle or after insemination and divided into isthmus and ampullary parts. This study demonstrated lower mRNA (in the isthmus and ampulla; p
