SLIDE 12
(Thomas Hildebrandt)

You can use ultrasound to prove the reproductive abilities not only in female; we are able to use ultrasound in males. It's much more difficult because they are not as well trained and they are not as calm as females, but here is a very important elephant: Onyx. Nancy Pratt will speak about him in her talk. You can see his accessory genital glands, and we use this to verify from which position came the semen during the ejaculation. And it's only the beginning, and we need a lot more interpretation, but I think in the future ultrasound will play a very important role in reproductive biology in elephants.
