Look where he got the bodies from and then better not dig deeper:
In 2008, the front page of the exhibition website had a disclaimer describing the presumed origin of the bodies and fetuses:
Disclaimer:
-This exhibit displays human remains of Chinese citizens or residents which were originally received by the Chinese Bureau of Police. The Chinese Bureau of Police may receive bodies from Chinese prisons. Premier cannot independently verify that the human remains you are viewing are not those of persons who were incarcerated in Chinese prisons.-This exhibit displays full body cadavers as well as human body parts, organs, fetuses and embryos that come from cadavers of Chinese citizens or residents.

BERLIN (Reuters) – Gunther von Hagens, a German anatomist famous for his controversial Body World exhibition displaying plastinated bodies, is now selling human and animal body parts — even as jewelry — online.
The move has provoked strong condemnation from German churches which accuse him of degrading human dignity.
A whole body from www.plastination-products.com costs about 70,000 euros ($97,400), torsos start at 55,644 euros and heads come in at around 22,000 euros each — excluding postage and packaging.
For those on a tighter budget, transparent body slices are available from 115 euros each.

But these real body parts — which have undergone plastination, a process which replaces water and fat with plastic for preservation purposes — are not available to everyone.
Only “qualified users” who can provide written proof that they intend to use the parts for research, teaching or medical purposes can place an order.
