The potential impact of sperm encapsulation technology on the importance of timing of artificial insemination: a perspective in the light of published work

Abstract

To facilitate artificial insemination with encapsulated spermatozoa independently of oestrus, ways must be found to extend the life of spermatozoa at body temperature, and to devise encapsulation procedures which will allow progressive release of viable spermatozoa over several days. In the past, the most common approach to the preservation of semen has been the principle of reduced temperature. However, the research literature presents several promising clues to the resolution of these problems; these are reviewed, and new directions are identified and explored. The potential impact of a successful encapsulation technology is recognized as the driving force for implementing the novel research required.
