The embryo transfer is a biotechnological technique that allows increasing the descendant of animals with high genetic value. The positive results, represented in pregnancy after the application of this technique, are affected by some factors that are inherent to the donor, the embryo, the technique, and the recipients which receive a strange embryo in the uterus allowing pregnancy. This review describes some factors affecting the reproductive efficiency of the recipients of bovine embryos within a program of embryo transfer. Its important to evaluate the parameters in this kind of recipients, as race, age, physiological status, health status, weight, reproductive tract integrity and management, and also too monitoring the ovarian structures while the estrus synchronization, and within previous and posterior stages in embryo transfer procedure. Therefore an optimum follicular development will be determinant to corpus luteum formation which generates enough serum progesterone concentrations to offer a right uterine environment allowing the optimum embryo development. Controlling the factors that affect the efficiency of the embryo transfer, it will obtain an increasing of positive results represented in pregnancies and births of individuals come from animals with high genetic value. |
