Researchers led by XY Inc., a global biotech company in Fort Collins, Colo., were recently successful in their quest to produce the first sex-selected offspring of the world’s first sex-selected mare and first sex-selected stallion. “First Lady” was born April 20. The filly was produced via artificial insemination (AI) using an extremely low dose of fresh, sexed sperm.

First Lady’s dam, “Call Me Madam,” captured global attention in 1998 as the first horse in the world to have her sex selected prior to conception via a cutting-edge cell-sorting technology developed by researchers led by XY Inc. (see article #1012)
