Q: My colleague's son, 32 years old, appears to be heading towards impotency. Are there any medical tests like blood tests, etc that can indicate symptoms of impotency?

A:Of course, many elaborate tests are nowadays available to check if your colleague's son has impotence (erectile dysfunction). These include penile blood flow studies, hormonal evaluation, and rigidity measurements. All these are discussed in detail on www.andrology.com and www.AndromedaAndrologyCenter.com.
