Ultrasound as a mechanical method for male dog contraception

Reprod Domest Anim. 2009 Jul:44 Suppl 2:326-8. doi: 10.1111/j.1439-0531.2009.01426.x.


Therapeutic ultrasound (1.5 W/cm(2)) was investigated for its effect upon testicular size and consistency and semen quality in five dogs. Dogs were treated every other day with a total of three treatments and were examined up to 2 weeks after treatment. There was some tenderness after treatment and a significant decrease in testicular size and semen quality. This method may provide a suitable contraception technique in dogs and requires further investigation.
