2007 began with a breakthrough concerning the relation between bone marrow and semen production. In series of studies stem cells were taken from a bone marrow and it was found that they may be able to become sperm cells not earlier that 3 to 5 years. This practically means that if you overly active sexually it will lead to weakened bones due to the specific nature of sperm production - semen contains human growth hormone, testosterone, prostaglandins (a two edged blade), alpha2-macroglobulin, Insulin-like growth factor I, different amino acids and minerals and other pharmaceutical proteins.
