Answer :
Answer:
Explanation:
Nitrogen is use to store semen for artificial insemination because if it's inert characteristics which it help to maintain the semen inertness and also it maintain the low temperature of the semen which is good for it's quality.
Nitrogen also help to prevent it's biological deterioration thereby maintaining it's viability and effectiveness.
Nitrogen is used in artificial insemination for storing semen at -196°C, a temperature that preserves the viability and fertility of sperm cells over long periods. The freezing process involves a protective semen extender mixture that is slowly cooled, then frozen in nitrogen vapour, and finally stored in a liquid nitrogen refrigerator.
Nitrogen is used for the storage of semen in artificial insemination because it is capable of maintaining extremely cold temperatures that are necessary for the preservation of biological materials. Frozen semen requires a stable, very low-temperature environment to keep sperm cells viable over long periods. Liquid nitrogen, with its boiling point at
-196°C, is ideal for creating such an environment.
During the semen freezing process, a semen extender containing nutrients, protectants, and buffers is mixed with the semen. This mixture is gradually cooled to 5°C, equilibrated, packed into straws, and finally frozen in nitrogen vapour. Lastly, it is stored in vacuum-sealed liquid nitrogen refrigerators, providing an uninterrupted, ultra-cold state to preserve the sperm's fertility functions.
By using this method, semen can be extended in volume for multiple inseminations and protected during freezing, which significantly enhances reproductive efficiency and allows for fertility management, such as sperm donation and sex selection.
