چکیده

The in vitro production of bovine embryos by in vitro fertilization or nuclear transfer procedures is a valuable tool in wide routine use for both scientific and commercial purposes. However, this technology is associated with in utero abnormalities that may culminate in increased rates of pregnancy losses, hydrops of the fetal membranes, prolonged gestation, diminished signs of parturition, dystocia, and birth of large calves with lower postnatal survival. Understanding morphological, physiological and molecular features in IVP-derived pregnancies will be of significance for the prevention or attenuation of such abnormalities, with direct scientific and economical implications.
