I’m interested in sperm cryopreservation. Sperm are exposed to many types of damage during cooling and freezing processes. Improving sperm cryo-survivability and quality after thawing, but th emost important one is the one that targets sperm themselves. One strategy is to adjust the cholesterol/phospholipid ratio of the sperm plasma membrane through using cholesterol loaded cyclodextrins to deliver cholesterol to sperm plasma membrane. Increasing cholesterol content of sperm membrane is expected to improve sperm quality after thawing and in turn, fertility.
