Fertility In Rabbits Inseminated With Diluted or Washed Spermatozoa

Abstract

In a previous communication (Wales, Martin, and O'Shea 1965) the number of spermatozoa inseminated, rather than the dilution rate, appeared important in controlling the number oflitters produced. On the other hand Chang (1946) and Cheng and Casida (1948) have indicated that the degree of dilution, rather than the number of spermatozoa, is a factor in determining the number of ova cleaved. The present experiments were undertaken to examine this apparent difference.
