title: Breeding soundness examinations of rams and bucks, a review.
abstract: Breeding soundness examinations of rams and bucks may be performed by veterinarians as a service for clients. A physical examination for breeding soundness includes a general examination for health with special consideration of the reproductive organs. Careful examination of the penis, prepuce, and testicles may reveal diseases or abnormalities which decrease reproductive potential. Rams with small or hypoplastic testicles are unsatisfactory potential breeders as testicle size is positively related to sperm production. Libido may be assessed during semen collection procedures or from observations of the owner. Semen quality may be evaluated using tests for motility, concentration, and morphology of spermatozoa. Rams may be declared satisfactory, questionable, or unsatisfactory potential breeders as a result of the examination.
