An enormous number of strains of hereditarily designed creatures have been produced around the world. Sperm safeguarding is a fundamental instrument for keeping up these strains as future hereditary assets. Besides, the danger of hereditary and microbial sullying during reproducing has been diminished by sperm protection. For the most part, sperm is saved in fluid nitrogen. Despite the fact that this is a highest quality level technique, it is expensive since particular gear and a consistent gracefully of fluid nitrogen is required. Posterity can be delivered from oocytes treated with sperm after freeze-drying , and victories have been accounted for in mice, rodents, hamsters and bunnies. Comparable examination is presently being attempted on household creatures and primates. Safeguarding of sperm by freezedrying is a creative technique since fluid nitrogen isn't required. Extra points of interest of freeze-dried sperm are that they can be put away at 4°C for quite a while, and put away and shipped for brief periods at room temperature without the utilization of fluid nitrogen or dry ice as cooling operators. Besides, it has been shown that mouse and rodent sperm can be saved for quite a while after freeze-drying utilizing a basic arrangement containing 10 mM Tris and 1 mM EDTA (Ethylenediaminetetraacetic Acid) balanced pH~8.0 [2,3]. Transient safeguarding of freeze-dried sperm at room temperature additionally prompted simpler oversea transportation of protected strains. Likewise, significant strains can be put away incidentally at room temperature even in case of a force disappointment, interference to the fluid nitrogen gracefully, or different crises brought about by fiascos, for example, tremors and tropical storms. Freeze-drying of sperm, as opposed to cryopreservation, is required to turn into another basic protection strategy for hereditary assets. Procedures to deliver hereditarily designed creatures have been set up. Despite the fact that it got conceivable to deliver knockout creatures by buildup of Embryonic Stem (ES) cell, a basic and viable technique was accounted for as of late whereby knockout creatures were delivered by the presentation of Zinc-Finger Nucleases (ZFNs)  and Transcription Activator-Like Effector Nucleases (TALENs)  without utilizing ES cell. Co-infusion of freeze-dried sperm and exogenous DNA into oocytes is one of the strategies to create transgenic creatures . This implies freeze-dried sperm can be utilized to create transgenic and knockout creatures by co-infusion of exogenous DNA/RNA. Freeze-drying of sperm can contribute not exclusively to the conservation technique for hereditary assets, yet additionally to the straightforward and compelling creation strategy for hereditarily designed creatures. This recommends in future fluid nitrogen ought not to be important to safeguard sperm. These reports propose re-thought of the conservation technique for sperm and resulting applications.
