Testicular changes in heroin addicts

While working with testicular changes in users of AAS, a suspicion that opioid abuse may lead to similar changes has risen. To investigate this possibility, collaboration with the Institute of Forensic Medicine in Budapest started. Unlike the situation in Sweden, where the majority of drug addicts are polydrug users, there is a large group of addicts in the Budapest region that only use heroin. This provides an opportunity to study changes in relation to only one exposure factor. The study is performed in collaboration with Professor Eva Keller, Semmelweis University.
