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.
