Is there really such a thing as Male Menopause or Andropause?

Every so often I hear the phrase “male menopause” or more accurately andropause.
Websites I’ve found through Google are commercial sites advocating Hormone Replacement Therapy.

I also searched Cecil’s columns & the message board archive before posting.

Is there actually such a condition?
What’s the current thinking in the medical community?
