Biological factors may influence hormonal umbalances in utero, and the influence could skew an unborn baby’s future sexual orientation. To test this theory, scientists at the U.S. Sheep Experiment Station in Oregon have identified rams who show an interest in mounting other rams, electro-ejaculated them to collect sperm, and used the sperm to impregnate ewes. The offspring rams will be tested to see if they show a homosexual orientation.
