How do I prepare my males for sperm collection? The highest quality sperm is harvested from young males, 8-16 weeks old, that have been housed apart from females for at least three days.
How many breeders should I have in my colony before starting cryopreservation? For Speed Cryo, you should have at least three productive breeding cages in your colony prior to starting. You can start Speed Cryo by shipping two proven breeder males to the CMMR. Once those males have been used to generate embryos, you can ship another breeder male to complete the process. Males used for sperm collection are not recoverable for subsequent breeding. For all other cryopreservation services, be sure that you maintain at least one productive breeding cage in your colony until cryopreservation is complete. What can I withdraw from the CMMR? Mice: An investigator can withdraw cryopreserved mutant mice in the form of embryos, gametes or ES cells. The CMMR can also provide an investigator with live mice derived from any of the above cryopreserved specimens. Service charges depend on the form of mutant mice provided to the investigator.
