London, May 7 : Controversial German anatomy artist  is once again facing flak for unveiling a work showing two corpses having sexual intercourse.

The artwork will be part of von Hagens' latest plastination exhibition `Cycle of Life' in Berlin.

The artist defends the exhibit saying that it combines the two greatest taboos of sex and death and is a lesson in biology. He insists that it is "not meant to be sexually stimulating".

Politicians and church representatives are angry at the exhibit, and have called for it to be withdrawn. They have pronounced it pornographic and an insult to the dead.
