The German fighter Dennis Siver have tested positive for chorionic gonadotropin (hCG) at UFC 168 according to MMAFghting.com. Earlier Siver had a inconclusive drug test, and now the B-sample result confirm a positive drug test result. hCG is a hormone that is popularly called the “pregnancy hormone”, and the usual pregnancy tests are based on detection of increased levels of hCG in urine.
Within doping hCG used mainly by men after anabolic steroids use. The reason is that the use of anabolic steroids slows or stops the body’s natural testosterone production. This can cause testicular shrinkage because they no longer need to produce testosterone. We can now might assume that Dennis Siver has previously used anabolic steroids.
