Abstract	It is estimated that in the past five years, flow cytometric sorting of gender pre-selected sperm using DNA as the marker has produced over 30,000 offspring. The majority of these offspring were cattle for two reasons: 1) The cattle industry has accepted the use of gender specific sperm for commercial reproduction and 2) Cattle have a distinct advantage over swine in requiring a significantly lower number of spermatozoa for fertilization. In the swine industry, using gender pre-selected sperm has not progressed at the same pace. Nevertheless, the ability to pre select gender of the offspring in the pig is one of the most sought after reproductive innovations because it would have a huge economic impact on pork production by reducing animal maintenance costs and supporting production goals. However, the current methods for producing gender pre-selected sperm and then delivery to the uterus require development to make them more productive, efficient and cost effective in swine production. While porcine embryo transfer (ET) has been practiced for about 50 years in a research setting, it has been employed more recently to salvage a specific genotype from a disease scenario or for international transfer of valuable genetics. While ET is a practical application
