This book has been written to address the need for a comprehensive guide to the practical applications of veterinary andrology, frozen semen technology, and artificial insemination. The author has drawn on their extensive experience and research to provide clear and informative explanations of these subjects, accompanied by relevant illustrations. The book has been designed to be a valuable resource for scientists and managers working in frozen semen production stations, semen quality control laboratories, and andrological diagnosis laboratories, as well as students of andrology and artificial insemination. The book covers the topics outlined in the syllabus for the practical course of andrology and artificial insemination for undergraduate students of veterinary science, and will also serve as a useful teaching aid for graduate students of animal reproduction or veterinary andrology. The book does not aim to duplicate existing literature on the subject, but rather to provide a focused and practical guide to the subject matter.
