Veterinary Medicine and Science, Volume 11, Issue 2, March 2025.To model the hormonal environment of sheep during pregnancy, estradiol (E2), progesterone (P4) and interferon‐tau (IFN‐τ) were used. The sheep endometrial epithelial cells (sEECs) were then stimulated with different concentrations of lipopolysaccharide (LPS) to determine suitable concentrations for inducing inflammation, while FABP4 expression was ...

Regulation of intraluteal production of prostaglandins [PDF]
, 2003 There is clear evidence for intraluteal production of prostaglandins (PGs) in numerous species and under a variety of experimental conditions. In general, secretion of PGs appears to be elevated in the early corpus luteum (CL) and during the period of ...

Effects of Splenectomy on Luteolysis in Pseudopregnant Rabbits.
Journal of Veterinary Medical Science, 1995 The effects of splenectomy on luteolysis in pseudopregnant rabbits were observed. Pseudopregnancy was induced in the rabbits by mating with vasoligated mature males and injection of human chorionic gonadotrophin (D0). In these rabbits, the concentration of serum progesterone increased for 7 days after the induction of pseudopregnancy.

Unraveling the Clinical FSH Conundrum: Insights From the Small Ovarian Reserve Heifer Model
Molecular Reproduction and Development, Volume 92, Issue 2, February 2025.ABSTRACT High doses of follicle stimulating hormone (FSH) are used during ovarian stimulation to maximize the number of oocytes recovered for in vitro fertilization (IVF) during assisted reproductive technology (ART) in women. Whether high FSH doses are detrimental to embryo viability remains controversial.

The physiological role of macrophages in reproductive organs
Reproductive Medicine and Biology, Volume 24, Issue 1, January/December 2025.Abstract Background Macrophages are essential immune cells critical to reproductive physiology. They regulate key processes such as follicular development, ovulation, and luteinization in the ovaries. Macrophages are also involved in endometrial remodeling, immune tolerance, and placentation in the uterus.

Exacerbated conceptus signaling does not favor establishment of pregnancy in beef cattle
Journal of Animal Science and Biotechnology, 2018 Background Insufficient production of anti-luteolytic signals by the pre-attachment embryo is considered a major cause of pregnancy failure in cattle. We tested the hypothesis that transfer of multiple blastocysts (n = 5/recipient) and progesterone (P4 ...
