The Side Effects of Testosterone Replacement

The side effects that I think we follow most closely are symptoms mostly. You definitely, definitely, definitely get BPH prostate growth. People will complain that they're having more difficulty urinating. We follow PSA because there's a concern that people with maybe low grade prostate cancer, we stimulate the growth of that cancer. The dihydrotestosterone, the most potent derivative of testosterone does cause hair loss. And so there are some real side effects even in this trial that was both, I think, planned and run in a way to not show harm.
