Homo issues are common in nearly every species. Years back a fellow researcher worked with sheep. A gay ram is not an issue if one has a 1000 animals. In a hobby flock with only a single ram, however, a breeding season could be a complete loss. Gay issues in sheep are at about a 5 to 10% rate.
The research project involved hopping up rams on every conceivable hormone possible in an attempt to kick them into gear using both blood and brain pump injections. Shipped in some really hot ewes from Nevada, and not a single ram came around. It's a wiring issue as opposed to hormones.
Hormones are often used in AI breeding programs to determine when cows are ready for breeding. In those instances a cow is hopped up with male hormones, and she will then exhibit male behavior humping anything that smells or postures correctly. When she singles out an individual, it's hustled into the chute and inseminated.
Have a nephew that's come out, and he's sat literally in tears telling his mom and grandmother that he'd do anything to be straight. He is a very unhappy kid.
