This review focuses on the paracrine and endocrine actions of interferon tau (IFNT) during
pregnancy recognition and establishment in ruminants. Pregnancy recognition involves the …

Metabolic regulation plays important roles in embryo development and uterine receptivity
during early pregnancy, ultimately influencing pregnancy efficiency in mammals. The …

A major unresolved issue is how the uterus influences infertility and subfertility in cattle.
Serial embryo transfer was previously used to classify heifers as high-fertile (HF), subfertile …

Progesterone (P4) acts via the endometrium to promote conceptus growth and implantation
for pregnancy establishment. Many cells release extracellular vesicles (EVs) that are …

Secretions of the endometrium are vital for peri-implantation growth and development of the
sheep conceptus. Extracellular vesicles (EVs) are present in the uterine lumen, emanate …

Oviduct fluid extracellular vesicles (oEVs) have been proposed as bringing key molecules to
the early developing embryo. In order to evaluate the changes induced by oEVs on embryo …

This review integrates established and new information on the factors and pathways
regulating conceptus–endometrial interactions, conceptus elongation and establishment of …

Pregnancy establishment in cattle is contingent on conceptus elongation—a fundamental
developmental event coinciding with the time during which most pregnancies fail …

The objectives were to determine the effects of supplementing docosahexaenoic acid (DHA)-
rich algae on reproduction of dairy cows. Holstein cows were assigned randomly to either a …

This study combined in vitro production of bovine blastocysts, multiple embryo transfer
techniques, and a conceptus-endometrial explant co-culture system to test the hypothesis …
