The corpus luteum (CL) is critical for establishment and maintenance of pregnancy in all
mammals. However, the fate of the CL in ruminants is dependent on the presence of a …

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 …

[EN] For many years prostaglandin E2 and prostaglandin F2a have been known to exert
luteotrophic and luteolytic actions on the corpus luteum (CL) of most mammalian species …

Current and emerging concepts on regulation of bovine corpus luteum function by various
metabolites of arachidonic acid are reviewed. A series of experiments are presented which …

Prostaglandin (PG) F2α that is released from the uterus is essential for spontaneous
luteolysis in cattle. Although PGF2α and its analogues are extensively used to synchronize …

The luteal phase in dogs is governed by many poorly understood regulatory mechanisms.
Functioning of the corpus luteum (CL) is unaffected by hysterectomy. Recently, the role of …

Secretion of progesterone from the corpus luteum is required for normal pregnancy in all
domestic animals. However, if pregnancy does not occur following estrus and mating …

In ruminants, uterine pulses of prostaglandin (PG) F2α characterize luteolysis, while
increased PGE2/PGE1 distinguish early pregnancy. This study evaluated intrauterine (IU) …

Prostaglandins (PGs) are important regulators of the early corpus luteum (CL) in the dog.
Whereas, initially, CL is gonadotropin independent, in the second half of its lifespan …

Prostaglandin F2α (PGF) induces the precipitous loss of steroidogenic capabilities and
cellular death in the corpus luteum of many species, yet the molecular mechanisms …
