SLIDE 7
(Thomas Hildebrandt)

This is a very common disease which you are not able to recognize with endocrinological methods is the development of tumors, benign tumors in the uterus which you find only in Asian elephants. It was never found in African elephants, the development of such tumors. Here are the ovaries on both sides; you can see in the uterus such spherical structures which have a white color. And if you look in ultrasound you find the same spherical structure. And we found out that such foreign bodies in the uterine wall have a big influence on the fertility rate. Females with these foreign bodies can have a normal cycle but will never get pregnant because these foreign bodies have an influence on the sperm transport system. The sperm must travel about one meter 40 centimeters, the sperm must be transported from the uterus by active movement.
