In ruminants, endometrial prostaglandin F2α (PGF2α) is responsible for luteolysis and
prostaglandin E2 (PGE2) is thought to be involved in maternal recognition of pregnancy. In …

Contents Cyclooxygenase (COX) is the rate‐limiting enzyme that catalyses the initial step in
prostaglandins (PGs) production. In the present studies, endometrial COX‐1 and COX‐2 …

Prostaglandins (PGs) are important regulators of reproductive functions. In ruminants,
interferon (IFN)-τ is the embryonic signal responsible for recognition of pregnancy. This is …

In ruminants, the production of prostaglandins by the endometrium is critical for recognition
of pregnancy. In the absence of an embryonic signal, luteolytic pulses of PGF2 are released …

In this study we investigated the expression of the two cyclooxygenases, cox-1 and-2, in
sheep uterine tissues during the estrous cycle and early pregnancy. We identified the cox-2 …

Luteolysis in domestic species is mediated by the release of luteolytic pulses of
prostaglandin (PG) F2α by the uterus at the end of diestrus, which must be suppressed by …

Prostaglandins are involved in the regulation of several reproductive processes such as
ovulation, luteolysis, and establishment of pregnancy. Prostaglandin E2 (PGE2) appears to …

Endometrial prostaglandins (PGs) and the PGE2/PGF2α ratio play an important role in
regulating the estrous cycle and establishment of pregnancy. The enzymes downstream of …

Prostaglandins are involved in mediating several important processes in mammalian
reproduction, including the initiation of parturition. In the present study, we examined the …

Abstract Background Cyclooxygenases (COXs) are the rate limiting enzymes in the process
of prostaglandins (PGs) synthesis, which are critical regulators of a number of reproductive …
