Injections of sclerosing agents into the caudae of the epididymides of adult and prepubertal dogs induced a long-lasting and probably irreversible azoospermia. The technique is easy to do and inexpensive, does not seem to cause undesirable side effects, and appears suitable for large-scale sterilization programs in male dogs.
