Generally, individuals with an odd number of chromosomes are not fertile. Such individuals cannot make proper pairs of homologous chromosomes during meiosis. Thus such organisms cannot make viable gametes, and hence they are infertile.
But in the real world, nothing is static. There are undoubtedly some exceptions, so there are several species of animals that have odd numbers of chromosomes and are fertile, such as certain types of fish, amphibians, and reptiles. For example, the Mexican tetra fish and the Chinese soft-shelled turtle.
