Testosterone Use May Increase Blood-Clot Risk Temporarily

Men who use prescription testosterone may face an increased risk of blood clots in the first six months of using the hormone, a new study from the United Kingdom finds. For comparison, the study also included more than 900,000 men in the U.K. who had not been diagnosed with a blood clot during that time period. The results showed that the men using testosterone had a 63 percent higher risk of blood clots in the first six months of therapy than the men who had never used testosterone.
