A new development in the cryopreservation of sperm.
Recent developments in in vitro fertilization have made it necessary to develop better methods for sperm cryopreservation. This article sets out the cryobiological and physical background relevant to sperm cryopreservation together with some new observations on the morphology of sperm in the frozen state. It also provides new data and analysis using a recently developed improved method of cryopreservation.
