Caprine Semen Cryopreservation and the Factors Affecting it: An Overview
Amit Sharma1* and Pankaj Sood2
ABSTRACT
Semen cryopreservation is a complex process that which involves balancing many factors in order to obtain satisfactory results. It causes ultrastructural, biochemical and functional damage to the spermatozoa leading to reduced motility, viability, impaired transport and fertility. Caprine sperms are extremely sensitive to cryopreservation compared to other species which is mainly attributed to the compositional variation of the sperm plasma membrane. Different factors affect affects the semen cryopreservation viz. species, breed, semen collection technique, collection season, extender composition, type of cryoprotectant used, cooling rate, equilibration time, freezing and thawing rate. All these factors should be given due credit for achieving better post-thaw post thaw quality of semen to be utilized in different advanced reproductive techniques.
