Influence of male surgical sterilization on the copulatory behavior and reproduction of Brandtu27s vole

摘要

The influence of sterilized male on the copulatory behavior and reproduction of Brandt′s vole was studied by using the method of surgical sterilization. Male surgical sterilization did not influence the copulatory behavior of Brandtu27s vole. Mating times with intact mates and litter size of female Brandt′s voles in male sterilized groups decreased compared with the control groups. The results supported the hypothesis of competitively reproductive interference of sterilized males. Thus, sterilization can be a viable method to control voles.
