dc.description.abstractIn 1952, researchers Christopher Polge and Lionel Edward Aston Rowson, who worked at the Animal Research Center in Cambridge, England, detailed several experiments on protocols for freezing bull semen for use in the artificial insemination of cows. Freezing sperm extends the life of a viable sperm sample and allows it to be used at later times, such as in artificial insemination. The researchers examined the effects of freezing conditions on bull sperm and how well they produce fertilized embryos once thawed. Polge and Rowson concluded that bull sperm can retain its fertility throughout the freezing process and that frozen bull sperm can yield pregnancy rates of up to seventy-nine percent. Polge and Rowson provided the first conclusive evidence that frozen mammalian sperm, once thawed, can produce viable pregnancies.en_US
