Varicoceles, which are dilated or enlarged veins in the testicles, are a common problem for men. They've been linked with male fertility problems for many years, but new research has shown that they can interfere with the production of testosterone. Lower levels of testosterone can have an impact on men's energy levels and muscle strength as well as affecting fertility.
As many as fifteen percent of men have varicoceles, but no medical action is usually taken unless they are painful or thought to be causing infertility. However, the new research suggests that it may be a good idea to opt for microsurgery earlier rather than later in order to prevent future problems.
