Pregnancy-associated glycoproteins (PAGs) are abundantly expressed products of the
placenta of species within the Cetartiodactyla order (even-toed ungulates). They are …

Elongation of the preimplantation conceptus is a prerequisite for successful pregnancy in
ruminants and depends on histotroph secretion by the endometrium. Lipids are an essential …

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 …

Establishment of pregnancy in cattle is complex and encompasses ovulation, fertilization,
blastocyst formation and growth into an elongated conceptus, pregnancy recognition …

In cattle, conceptus development after elongation relies on well-characterized, paracrine
interactions with the hosting maternal reproductive tract. However, it was unrecognized …

Uterine infection is associated with infertility in women and dairy cows, even after the
resolution of infection. However, the mechanisms causing this persistent infertility are …

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 …

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