The U.S. is currently the leader in cattle embryo exports, shipping off about 15,000 embryos a year, according to the American Embryo Transfer Association, the trade group that certifies and tracks ET procedures. The AETA's numbers are a rough estimate, given that embryo-transfer service providers voluntarily submit data on an annual basis, and many businesses resist sharing information for fear competitors will encroach on their market.
