It is well established that in ruminants, and in other species with estrous cycles, luteal
regression is stimulated by the episodic release of prostaglandin F2α (PGF2α) from the …

The new corpora lutea (CLs) in pigs are formed from the preovulatory follicles after the
luteinizing hormone (LH) surge. However, total autonomy and independence of CLs from LH …

In swine, episodic release of prostaglandin (PG) F 2α is responsible for corpus luteum (CL)
regression, but the stimulus for its secretion from the endometrium has not been established …

The role of endogenous prostaglandin F2α (PGF) in the induction of luteolysis by exogenous
PGF was studied by simultaneous inhibition of endogenous PGF with flunixin meglumine …

Luteal cells were obtained by digestion of luteal tissue of cyclic (day 12) and early pregnant
(days 12, 20 and 30) pigs. Suspensions of the dispersed luteal cells (5× 10 4 cells ml− 1) …

The aim of this study was to characterize certain prostaglandin family members in the bovine
corpus luteum (CL) during the estrous cycle and pregnancy. The CL tissue was assigned to …

Contents Prostaglandin F2α (PGF2α) is a main luteolytic factor in vivo; however, its direct
luteolytic influence on steroidogenic cells of bovine corpus luteum (CL) is controversial and …

Porcine corpora lutea (CL) develop sensitivity to regression by prostaglandin F2α (PGF2α),
termed luteolytic capacity, about 13 d after estrus. We postulated that PGF2α regulation of …

Prostaglandin F2a (PGF2a) released from the uterus causes alterations in luteal blood flow,
reduces progesterone secretion, and induces luteolysis in the bovine corpus luteum (CL) …
