The procedure of “pharmacologically inducing ex copula Ejaculation” may be used to collect stallion’s sperm from horses suffering from physical disabilities or ejaculatory malfunction. This procedure is also known as “chemical ejaculation” and may prove beneficial for horses suffering from severe musculoskeletal problems, neurologic defects, penile paralysis or other issues. A pair of medications may be administered in a sequential order to achieve chemical ejaculation. Tricyclic antidepressant medication imipramine hydrochloride is used to lower the ejaculation threshold. About 30-75% of horses treated with imipramine-xylazine ejaculate. The volume of ejaculates is usually low and the sperm content high. Chemical ejaculation allows you to inseminate mares right away, and can also be frozen for future use. This chapter explains the steps involved in performing chemical ejaculation.
