Pregnancies from imipramine and xylazine-induced ex copula ejaculation in a disabled stallion.
Breeding or semen collection was attempted using: natural cover, manual stimulation, artificial vagina, pharmacologic induction of ejaculation, and electroejaculation. Sperm cells were recovered from the ductus deferens and epididymides post mortem. Only semen collected ex copula by imipramine and xylazine treatment resulted in conceptions (4/5). This is the first report of pregnancies in horses from ex copula semen collection.
