In the 1980s, a breakthrough in semen-sexing technology was made by USDA researchers in Livermore, Calif., and Beltsville, Md. The patents for this technology were licensed to XY Inc., Fort Collins, Col., which performed a considerable amount of research during the 1990s to optimize efficiency of these sorting procedures. Commercialization of sexed semen in the United States was initiated with a 2003 license granted to Sexing Technologies (ST), now providing highly skilled personnel to staff their different laboratories around the world.

Sexing Technologies Inc. was created with the goal of producing Sexed Sorted Semen around the globe. In 2003 they acquired the license and in 2004 the first lab started operations in Navasota, TX. Sexing Technologies success along with the success of the technology is in big part due to the addition of the majority of the big semen companies in the world.

In 2007 Sexing Technologies acquired XY Inc; this is a major step towards the improvement of the technology. This acquisition will make possible for ST to put its know-how in the practical application of the technology in conjunction with the R&D capabilities of its personal to take this product to the next step.
