Abstract
None:
Two male marmosets underwent vasectomy without complications. Azoospermia was confirmed by computer-assisted semen analysis (CASA) 5 weeks later. Both were co-housed with embryo transfer recipient females 6 weeks after surgery. Vasectomy may be accompanied by post-vasectomy semen analysis such as CASA, to ensure safe and reliable sterilization for research and captive breeding management in marmosets.
