The Timing of the Maternal Recognition of Pregnancy Is Specific to Individual Mares
Animals, 2023 The present experiment aimed at determining whether the timing of the maternal recognition of pregnancy (MRP) was specific to individual mares by determining when luteostasis, a failure to return to oestrus, reliably occurred in individuals following ...

Loss of luteotropic prostaglandin E plays an important role in the regulation of luteolysis in women [PDF]
Molecular human reproduction, 2017 STUDY QUESTION: Do intraluteal prostaglandins (PG) contribute to luteal regulation in women? SUMMARY ANSWER: Prostaglandin E (PGE), which is produced in human granulosa-lutein cells stimulated with luteotropic hCG, exerts similar luteotropic effects to ...

Multiple roles of hypoxia in bovine corpus luteum
The Journal of Reproduction and Development, 2020 There has been increasing interest in the role of hypoxia in the microenvironment of organs, because of the discovery of hypoxia-inducible factor-1 (HIF1), which acts as a transcription factor for many genes activated specifically under hypoxic ...
