Does osteoporosis affect men when they are middle aged?

Yes, men lose bone density as they age, just like women. There are two important differences that 'help men' have less of a problem - but they can still have a problem.

One: men tend to have larger bones and therefore 'more bone' to begin with than women (but if you are small boned like I am, you/I have increased risks).

Two: women go through a period of rapid bone loss after menopause, and obviously, men do not face this issue.

So, eat healthy foods. Get regular exercise. Don't smoke or drink. And take a quality vitamin/mineral supplement to be sure you aren't 'short' on important nutrients. And, be sure to supplement with extra vitamin D because deficiency of Vitamin D has become a pandemic in the U.S. and it has significant consequences for bone density.

Best wishes and good luck!
