Certain types of infertility found in various animal populations may be due to genetic causes. This type of lowered reproduction becomes increasingly important in the male as the use of artificial insemination extends to more species. The extensive use of affected males tends to increase the frequency of these deleterious alleles in a population and thus lower the rate of reproduction of the species. In poultry, poor reproductive performance is a commercially important problem in broiler and turkey production. Any information, either genetic or physiological in nature, which might help correct this problem should be met with prompt attention. fr
