In vitro fertilization and embryo transfer in domestic animals: applications in animals and implications for humans.
Extensive research has been conducted in domestic animals, particularly in cattle, in the reproductive technologies of sperm handling, capacitation, and acrosome reaction, superovulation, and embryo handling, sexing, bisection, cryopreservation, and transfer. Because of the economic importance of cattle these technologies have been tested and improved under clinical conditions. The results of employing these procedures are available on tens of thousands of pregnancies and offspring. This information has implications in applying some of the same technologies in human reproduction. The large number of normal progeny produced in cattle after a long prenatal development period, similar to humans, provides some assurance that these technologies, carefully applied, are safe. The basis for these conclusions is documented in the publications cited in this review.
