Veterinary Andrology and Reproductive Techniques

INTRODUCTION

• Any deviation from normal morphological structure of spermatozoa is called as abnormal sperm.
• Every ejaculate will have some abnormal sperms in it.
• An increased prevalence of abnormal sperm is associated with a decrease in fertility.
• The appearance of an increased number of abnormal sperm in the ejaculate is a reflection of lesions of the testes and/or the excurrent duct system and provides a convenient clinical diagnostic aid.

Each ejaculate collected from male animals will have some abnormal sperms. If it exceeds beyond a level the fertility is affected.
