ABSTRACT:
Sperm, oocyte, and embryo survival and function is improved in vivo or in vitro by the use of a polysaccharide containing arabinose, galactose and/or hexuronic acid. In particular, a nonspermicidal lubricant containing such a polysaccharide (e.g., gum arabic, pectin, or galacturonic acid) increases the fertilization potential of the sperm during coitus, artificial insemination or sperm collection. Similarly, a freezing medium containing a polysaccharide containing arabinose, galactose and/or hexuronic acid enhances sperm, oocyte, or embryo viability.
