The evolution of the bull breeding soundness examination (BBSE) that is currently in use is a testimony to the foresight and persistence of a group of veterinarians and animal scientists who identified a problem, specifically subfertility in bulls, and worked to continually improve the metrics that could be used to validate the fertility or subfertility of a : Richard M. Hopper. Sperm motility and morphology evaluations are performed as described for the bull (see Breeding Soundness Examination of Bulls); however, the sperm concentration is much lower in stallions (typically – million/mL), so only individual sperm motility is evaluated. Assessment of motility should be performed with both raw semen and semen.
Breeding soundness refers to a bull's ability to get cows pregnant. A standard breeding soundness evaluation identifies bulls with substantial deficits in fertility, but does not consistently. Regardless of bull status, records of the breeding soundness exam should be available and retained for the duration of the bull’s time on the farm or ranch. These valuable documents contain much needed information for the veterinarian and owner should a problem arise, and can help interpret findings at the next breeding soundness exam.
Published by: VetLearn Foundation ISBN: Evaluation of Bulls for Breeding Soundness is an invaluable resource for all cattle veterinarians involved in reproductive management of dairy, beef, and particularly bull-breeding herds. An important part of any breeding soundness exam is an evaluation of sperm morphology. In the most fundamental case, the size and shape of the head, midpiece and tail are examined. Additional information can be gained by evaluating integrity of the acrosome and sperm membranes. Sperm from different species vary in size and shape.

The average breeding soundness exam costs between $55 to $65 per bull and depending on the veterinarian the cost can go down based on the volume of animals tested. Both Koziol and Armstrong believe the benefits of performing a yearly breeding soundness exam outweigh the costs and time it takes to do the exam.
In bulls, assessment of libido is often not possible during a routine breeding soundness examination (BSE). However, if possible, the bull should be observed serving cows to allow assessment of his desire to breed, ease of mounting, ability to achieve erection and extend the penis, and presence of penile deviation or other abnormalities that may prevent successful.
