title: Electroejaculation in the domestic cat.
abstract: A method of electroejaculation for tomcats is described. Normal sperm counts in 4 cats ranged from 6 to 13 X 10(6)/ejaculate. There was a great deal of variation between collections from the same cat indicating the necessity for at least 5 collections when assessing the fertility of a tomcat. Sperm counts were higher in the latter half of the year, at the time of increased sexual activity for cats in the Brisbane area. The volume of semen collected by electroejaculation increased in direct proportion to the length of electrical stimulation, hence, volume is not a reliable criterion for the appraisal of semen. However, results have indicated that semen volume tends to increase from July to December, thus indicating increased accessory gland activity during the breeding season. As this procedure does not cause any apparent discomfort or harmful effects there seems no reason to assume that it could not be used routinely on stud cats.
