Extract

The problem of sperm disinfection in mammals is not only interesting from the biological standpoint. It is of practical value especially in the horse-breeding industry.

Russia). See Iwanow, E., “Action de l'alcool sur les spermatozoïdes des mammifères. Expériences sur la fécondation des mammifères avec le sperme mélangé d'alcool,” C. R. Soc. Biol.

1 As an infective agent I selected T. equiperdum, which escapes with the blood of stallions suffering from dourine when lesions are produced in coitus, the parasites consequently infecting the sperm.

2 The mice received about 0·3–0·5 c.c. of salt solution containing 10 per cent, alcohol+ 5 drops of infective blood per 1 c.c. (See Note to Protocols of Experiments (p. 125) regarding this rough mode of dosage.)

1 The dosage by “drops” was very rough owing to the varying size of the drops expressed from the mouse's tail, the blood being collected in a fine pipette.

1 A preparation named “189,” manufactured in France, is being recommended as a specific remedy against trypanosomes; it may prove better suited for disinfecting the sperm than the drugs hitherto tested.
