The numbers of spermatozoa per insemination and the site of semen deposition in the uterine horn appear to interact to influence pregnancy rate. In two experiments, the effect of a single low dose (2 x 10(6) spermatozoa) intracornual insemination (LD

The aim of the study was to determine the efficiency of single fixed time deep intracornual insemination using 2 x 10(6) spermatozoa compared with single standard dose deep intracornual insemination and single and dual standard dose (40 x 10(6)) uter
