Clinical management of the subfertile stud dog

Many subfertile stud dogs can sire pups with appropriate management. Determination of the area of the problem (libido, ability to breed, semen quality) is the first step. Each of these areas can often be improved or managed. A complete history, physical examination, and semen evaluation should be performed on every patient. In specific cases, additional diagnostics may be helpful, including a CBC, biochemistry profile, urinalysis, semen cultures, ultrasonography, and biopsy. Management of breeding, including ovulation timing and intrauterine insemination, can be vital in dogs with low spermatozoal numbers or motility. Treatment of underlying prostatic disease can dramatically improve semen quality and fertility.
