Semen Banking and Cryobiology
نویسنده
چکیده
Cryo banking of spermatozoa is an essential aspect of fertility preservation. With the advancements in cryobiology and better understanding of cryoprotectants and assisted reproduction, indications for semen banking are expanding. The exponential developments that have occurred over the years in the field of cryopreservation have proved that frozen sperm is as good as fresh sperm in fertilizing oocytes. Semen banking has major role in fertility preservation in cancer patients.

Effect of pre-freeze semen quality, extender and cryoprotectant on the post-thaw quality of Asian elephant (Elephas maximus indicus) semen.
Semen cryopreservation and artificial insemination (AI) are potentially valuable methods for supporting the breeding management of endangered species like the Asian elephant. Cryopreservation of Asian elephant semen has however proven problematic with respect to maintenance of both adequate semen quality and fertility post-thaw. In this study, nine ejaculates from three adult bulls were used to...
متن کاملHow developments in cryobiology, reproductive technologies and conservation genomics could shape gene banking strategies for (farm) animals.
Many local breeds are currently at risk because of replacement by a limited number of specialized commercial breeds. Concurrently, for many breeds, allelic diversity within breeds declines because of inbreeding. Gene banking of germplasm may serve to secure the breeds and the alleles for any future use, for instance to recover a lost breed, to address new breeding goals, to support breeding sch...
متن کاملSemen banking: consideration on viral contamination in the era of new emerging viral infection
To construct a semen bank, the collection of donated semen has to be done and an important concern is the safety of collected semen. The contamination is a big problem. Basically, the infectious pathogens can exist within donated semen, hence, a good donor screening is very important. Although viruses have an indirect role in sperm quality, but the evidence in banked semen is presently lack. Th...
