Progesterone (P4) from the corpus luteum is critical for the establishment and maintenance
of pregnancy and plays a major role in regulating endometrial secretions essential for …

After parturition, dairy cows undergo a plethora of metabolic, inflammatory, and immunologic
changes to adapt to the onset of lactation. These changes are mainly due to the homeorhetic …

Women with polycystic ovary syndrome (PCOS) have hyperandrogenism and insulin
resistance and a high risk of miscarriage during pregnancy. Similarly, in rats, maternal …

The bovine pre-implantation embryo secretes bioactive molecules from early development
stages, but effects on endometrial function are reported to start only after elongation. Here …

We aimed to evaluate the effects and the interaction of size of the preovulatory follicle (POF)
and long-acting progesterone (P4) supplementation after timed-AI on CL function and …

Beef cows and ewes grazing native pastures are exposed to cycles of undernutrition that
reflect the seasonal variations of biomass production. In grazing dairy cows, the …

We aimed to study the association between CL characteristics assessed by color-Doppler
ultrasonography (Doppler-US) at the time of embryo transfer (ET) and pregnancy rate (P/ET) …

Cattle with subclinical endometritis (SCE) are sub-fertile and diagnosing subclinical uterine
disease remains a challenge. The hypothesis for this study was that endometrial …

In cattle, starting 4–5 days after estrus, preimplantation embryonic development occurs in
the confinement of the uterine lumen. Cells in the endometrial epithelial layer control the …

In cattle, molecular control of oviduct receptivity to the embryo is poorly understood. Here,
we used a bovine model for receptivity based on size of the pre-ovulatory follicle to compare …
