“…The other two parameters considered, agglutination and sticking-to-glass, were less directly informative as assessments of survival. Both have, by implication, been considered as indicating damage (Bangham & Hancock, 1955 ;Dott & Walton, 1960) ; however, agglutination can be reversible (see Lindahl, 1960) and we specifically noted that motile cells frequently stick to glass and to each other. That these are separate phenomena seems clear because they occurred separately and were affected differently by treatments.…”

The seminal plasma in sperm suspensions from boar, bull, rabbit, ram and stallion was replaced with simple defined media as completely as possible by a combination of centrifugation through Ficoll and dilution. After this process, motility declined and the cells showed a tendency to agglutinate and/or stick to glass. Varying the ionic strength of the medium had little effect upon these parameters but sperm motility was preserved better in the presence of serum albumin. When a number of purified proteins and other macromolecules were tested individually in this way for their motility-preserving ability, bovine or human serum albumin was consistently the most effective. Defatting the albumin or altering its nature by mild reduction, oxidation or alkylation had little detectable effect on its motility-preserving ability; the protein did not appear to be acting as a chelator of metal ions, for it could not be replaced by EDTA. The response of the spermatozoa to replacemrnt of seminal plasma varied between species: bull spermatozoa were particularly sensitive and serum albumin had little effect upon their subsequent motility.

“…These comments are made to provide an indication of the kind of frame of reference in which it seems desirable to consider the extensive studies of Lindahl and his co-workers (Lindahl & Kihlström, 1954;Lindahl & Nilsson, 1954Lindahl, Ingelman-Sundberg, Furuhjelm & Nilsson, 1956;Lindahl, 1956Lindahl, , 1959Lindahl, , 1960) on what he has termed antagglutins. The antagglutins are materials that can inhibit the spontaneous agglutination of washed spermatozoa of various animals.…”
