Sperm Morphology of Domestic Animals – J. H. Koziol, C. L. Armstrong

A practical guide to interpreting sperm morphology of domestic animals

Sperm Morphology of Domestic Animals is a concise, clinically-oriented resource for discovering any impairment to fertility caused by sperm anomalies in domesticated animals. As a bench-side reference, the book examines common sperm defects, their causes, and their prognosis for fertility.

An easy-to-use reference, it is organized according to the placement of the deformity in the sperm to increase the speed of consultation, and to help with diagnosing fertility issues. Focusing particularly on the bull, stud horse, boar, ram, buck, and dog, it contains hundreds of high-quality color images accompanied by brief descriptions for additional diagnostic help. Readers will find:

• An easy-to-use reference work that is suitable for use next to the microscope
• Organization according to location of abnormality
• Hundreds if high-quality color images for easy comparison
• Brief descriptions accompanying each photo, for additional diagnostic help

An ideal resource for veterinarians, andrologists, and veterinary students, Sperm Morphology of Domestic Animals fills a gap in current reproductive medicine resources with detailed information that is easy to consult.
