Sperm-mediated gene transfer (SMGT) is a transgenic technique involves transfer of the genes based on the spermability to bind spontaneously and internalize the exogenous DNA, and transport it into an oocyte during fertilization to produce genetically modified animals. Spermatozoa play a major role in transgenesis in virtually all species. Their ability to take up exogenous DNA molecules to transmit novel genetic information to the offspring after fertilization can be exploited. The assisted techniques like electroporation, lipofection, Restriction Enzyme Mediated Integration (REMI), Intracytoplasmic Sperm injection (ICSI) and linker based SMGT have been developed to increase the DNA uptake by the spermatozoa. SMGT can be regarded as a potential source of mutation for the host genome. Avian species, particularly chickens, have been increasingly used in transgenic research due to their inherent advantages, such as short generation times, high semen production and potential applications as transgenic bioreactors for heterologous protein production. The application of transgenic technology to domestic poultry offers an alternative to conventional practices for the improvement of this highly productive agricultural species and its use as a bioreactor model.
