SLIDE 9
(Thomas Hildebrandt)

The shape in the endometrium, which is the surface inside the uterus, you can use for detection of cycle and of normal or pathological changes. These are some pictures of the endometrium. That's a black line, but I think it's difficult to see so I will go on to the next picture.

Now we come to pregnancy. Ultrasound is very common in humans to detect pregnancies in women. But an elephant is much bigger and you need a special technique to find such pregnancies by ultrasound. That's an African culled elephant, and I use it to show the structure inside. The fetal cavity is very round, it's not elongated like in horses or cattle, and it's attached only with this stripe, which we have seen before which makes a scar in the uterus.
