Infertile men are also more likely to develop testicular cancer.

      A new study done by the University of California analyzed data from 22,562 male partners of couples requesting fertility treatment and found there may be a common underlying factor affecting the male reproductive system.

      “More than likely it's just that there is some share mechanism between the processes that bring about male infertility and the processes that bring about testicular cancer,” said Thomas Pool, the scientific director at The Fertility Center of San Antonio.

      There is a concern that male infertility is on the rise, but the strongest possibility is because of exposure to hormone-like chemicals in our everyday environment, Pool said. 

      “I don’t think it's anything to panic about,” he continued. “But it is something that now tells us in the fertility field that when we see this is that we just want to ensure that the male, if he is suffering from infertility himself... that he is aware of this.”

       Of those tested, 4,549 proved to have male factor infertility; the data was then crossed with the data from the cancer registry. The study found that men diagnosed with infertility were three times more likely to develop testicular cancer.

       “It is not the fertility therapy that is causing this,” Pool said. “Couples wanting fertility therapy should not use this as a reason not to have the procedures.”
