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

Administration of prostaglandin (PG) F2α in cattle during the mid-luteal phase (Days 8–12 of
the estrous cycle) drastically reduces the plasma progesterone concentrations and the …

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 …

Natural luteolysis involves multiple pulses of prostaglandin F2alpha (PGF) released by the
nonpregnant uterus. This study investigated expression of 18 genes from five distinct …

Prostaglandin (PG) F2α is the primary luteolysin in most species. A single treatment with
PGF2α will cause regression of the mid-cycle but not the early-cycle (Days 1-5 after estrus) …

Prostaglandin F2 alpha (PGF2alpha) brings about regression of the bovine corpus luteum
(CL). This luteolytic property of PGF2alpha is used in beef and dairy cattle to synchronize …

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 …

Prostaglandin (PG) F 2α released from the uterus in a pulsatile fashion is essential to induce
regression of the corpus luteum (CL) in the cow. In addition to the uterus, the CL has also …

In ruminants, the corpus luteum (CL) of early pregnancy is resistant to luteolysis.
Prostaglandin (PG) E 2 is considered a luteoprotective mediator. Early studies indicate that …

In heifers and mares, multiple pulses of prostaglandin F2alpha (PGF) are generally
associated with complete luteal regression. Although PGF pulses occur before and during …
