Abstract:
Sperm cryopreservation enables long term preservation of male germ plasm for future use in assisted reproduction, like artificial insemination (AI) and in vitro embryo production /transfer across the species. The ultimate aim of sperm cryopreservation for AI is genetic improvement of farm animals, controlled/desired breeding of valuable pet breeds and conservation of endangered species. A lot of efforts have been made for genetic improvement of dairy cattle through artificial insemination using cryopreserved semen. Therefore, protocols have been standardized for cattle and with some modifications for buffalo. Bull semen is actually the most studied sample for germplasm cryopreservation. Since zoologists deal with conservation of germplasm across the species, they have the opportunities of sperm cryopreservation across the species for sperm cryobanking for futuristic use in conservation breeding programs. In this context, fish sperm cryopreservation is of relevance for reducing inbreeding issues, genetic drift, synchronous breeding and transport of cryopreserved milt at distant hatcheries. However, fish sperm cryopreservation needs a lot of efforts for development of species-specific protocols. Amphibian and reptiles are most neglected group and many species of these groups are in danger of extinction. Conservation of amphibians and reptiles through gene banking is direly needed and Zoologists have the opportunity to work and develop sperm banks for conservation breeding programs. Avians and mammals are relatively well studied group, however many species need attention, specifically the endangered species and some breeds of livestock that are ignored due to excessive exploitation of commercially important breeds. All such avenues / opportunities and challenges for the Zoologists in the field of sperm cryopreservation will be discussed in the invited lecture.
