Preliminary Fertility Results from the Preservation of Bovine Semen at Room Temperatures

University of Illinois, Urbana

ABSTRACT

The preservation of fertility of semen at room temperature would be of great economic importance and would serve to facilitate the increased use of artificial insemination, especially in areas where refrigeration is not available. Numerous attempts to store sperm at room temperature have not been successful, because of the limited sperm survival obtained (1, 2, 3, 8, 9). Recent investigations at the University of Illinois, involving the effect of carbon dioxide on spermatozoa, have resulted in the development of a method which successfully preserves the motility and fertility of bovine semen for several days at room temperatures. Details concerning the effects of CO₂ on sperm motility, and the development of media for room-temperature storage, will soon be submitted for publication in this journal (6, 7). The effects of CO₂ on sperm metabolism are being published elsewhere (4, 5).

The preservation of bovine semen at room temperature has been achieved by incorporating CO₂ into a suitable diluent and hermetically sealing the diluted semen in ampules.
