Prostaglandins impact on ovarian, uterine, placental, and pituitary function to regulate
reproduction in female livestock. They play important roles in ovulation, luteal function …

The majority of pregnancy loss in ruminants occurs during the first three weeks after
conception, particularly during the period of conceptus elongation that occurs prior to …

This review integrates established and new information on the role of progesterone,
interferon tau (IFNT), and prostaglandins in uterine biology of ruminants. Establishment of …

Studies on the control of PGF 2α secretion by hormone receptors in the ovine uterus based
on in vivo infusion experiments in the autotransplanted uterus are summarized. In addition …

The establishment of pregnancy in ruminants occurs during the peri-implantation period and
involves the suppression of the endometrial luteolytic mechanism to maintain progesterone …

Abstract Ovine trophoblastic protein-1 (oTP-1), an early secretory protein of the sheep
blastocyst, was purified after culturing day 14–16 conceptuses for 24 h in vitro. The …

In ruminants, both the endometrium and the conceptus (embryo and associated
extraembryonic membranes) trophectoderm synthesizes and secretes prostaglandins (PG) …

Oestradiol acting on a progesterone-primed uterus stimulates prostaglandin (PG) F2α
synthesis by the endometrium. In some species (notably the sheep, cow and goat) oxytocin …

This review integrates established and new information on the biological role of ovarian
progesterone (P4) and interferon tau as well as conceptus-and endometrial-derived factors …

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 …
