ABSTRAK: Sperm plasma membrane
was rich unsaturated fatty acid and vulnerable to peroxydative damage.
Vulnerability sperm against lipid peroksidation could be caused by increased
cold shock. The peroxydative processed alter the structure of. sperm,
particularly in the membrane and akrosom, lost motility, metabolic changed and
the rapid released intraseluler component. This condition could be prevented by
adding antioxidants to semen extender, such as vitamin E and BHT. Vitamin E has
been proven to protected sperm plasma membrane during freezing to thawing,
while Butylated Hydroxytoluene (BHT) prevent the sperm plasma membrane damage
caused cold shock and provide protection against changes due to freezing.
Vitamin E and BHT prevent lipid peroksidation through its the hidrogen atom to
the radical peroksil rapidly. It can be concluded that an antioxidant could be
prevent damage the sperm plasma membrane was caused cold sho(:k and provide
protection against changes due to freezing and to prevent lipid peroksidation.
