Reproduction in Male Animals

Reducing infertility in agriculturally important males, including aquatic species, is of major importance for efficient animal production. The major factors that limit reproductive success in males include: lack of libido (sex drive), low production of sperm, or production of sperm with low fertility. In addition, to obtain large numbers of offspring from genetically superior males, it is often necessary to collect and preserve large quantities of sperm. NIFA has supported a number of basic and applied research projects to enhance and predict the fertility of genetically superior males.
