Semen Extender (Paperback)

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Semen extender is a liquid diluent added mixed with semen to preserve its fertilizing ability. The extender allows the semen to be freighted to the female, rather than requiring the male and female to be near to each other. Special freezing extender use also allows cryogenic preservation of sperm ("frozen semen"), which may be transported for use, or used on-site at a later date.The addition of extender to semen protects the sperm against possible damage by toxic seminal plasma, as well as providing nutrients and cooling buffers if the semen is to be cooled. In the case of freezing extenders, one or more penetrating cryoprotectants will be added. Typical cryoprotectants include glycerol, DMSO and dimethylformamide. Egg yolk, which has cryoprotective properties, is also a common component.
