Evaluation of infertility in the bitch

The majority of bitches that are brought to a veterinarian for reproductive evaluation are actually healthy. Infertility in the bitch is most commonly due to inappropriate breeding management rather than an inability to conceive. Before embarking on an exhaustive medical evaluation, it is important to obtain a thorough history and physical examination to identify any problems. Completion of a routine database assists in detecting significant systemic illness that may impact infertility. After consideration of history, physical examination, and minimum database, fertility problems are most commonly considered in one of four categories: abnormal estrous cycles, normal estrous cycles, failure to breed, or failure to carry a litter to term. This classification system aids in construction of a differential list and systematic evaluation of all differentials. The majority of diagnostic tests required are available to the general practitioner. Before any treatment for infertility, adequate health management must be ensured. Specific treatment for the most common causes of infertility is centered on appropriate breeding management. © 2002 Elsevier Science (USA).
