Although practitioners are often asked to collect semen and perform AI without detailed semen analysis, every sample of semen collected should be evaluated (at least progressive forward motility, total sperm count and morphology) before it is used for artificial insemination or cryopreservation. Most procedures used for semen deposition are neither detrimental to the bitch, nor interfere with animal welfare, and even allow protection against certain diseases.
