EurekAlert! -- A single injection of morphine to fight persistent pain in male rats is able to strongly reduce the hormone testosterone in the brain and plasma, according to a new paper published in Molecular Pain. The study, led by Anna Maria Aloisi, M.D., of the Department of Physiology – Section of Neuroscience and Applied Physiology at the University of Siena, Italy, Sbarro Institute for Cancer Research and Molecular Medicine at Temple University in Philadelphia, University of Siena, and the Human Health Foundation in Spoleto, Italy, showed that opioids had "long lasting genomic effects in body areas which contribute to strong central and peripheral testosterone levels" including the brain, the liver and the testis.
