    Abstract / Zusammenfassung

    A literature survey of causes of infertility and subfertility in the bitch serves as an introduction.The purpose of this work is to present a diagnostic approach to infertility that is suited for veterinary practices. In the course of this study, 61 dogs of 21 different breeds were examined and their fertility was evaluated. The animals were placed into 6 groups based on diagnostic data subjected to flow diagram analysis. The control groups 1 and 2 were comprised of 25 dogs. 18 dogs were placed in group 3 based on documentation of hormonal dysbalances. Group 4 consisted of 9 dogs with abnormalities of the uterus. Group 5 consisted of 12 dogswith suspected husbandry errors causing infertility. In 6 dogs o cause of infertility was diagnosable (group 6).in some cases, the placement of animals into groups was difficult due to the presence of more than one cause of infertility. Their individual parameters such as haematocrit, basal thyroxin levels or progesteron levels and the identification of bacterial pathogens from the vagina showed no direct relationship to fertility, but were, however, helpful in a systematic approach to diagnose sterility using the flow diagram developed for this purpose.A direct relationship between nutrition and fertility was not detectable under practice conditions.
    The successful diagnosis and treatment of fertility disturbances are greatly influences by owner compliance. Due to the special reproductive biology of monoestric bitches, some diagnostic measures are restricted to just a few days of the year. This limitation illustrates the need of a systematic diagnostic approach (possibly with the aid of an appropriate flow diagram) from the beginning, to efficiently use available diagnostic measures.
