What does treatment for prostate cancer consist of, and does it affect a male’s ability to have sex?

Marq JPAA asked:


A very close friend of ours has been diagnosed with prostate cancer (it really *isn’t* my partner or me!) and we were wondering what his treatment options might be.

If the prostate gland is removed, does that eliminate the ability to have sex?

Probably best to have an older person answer this: it’s pretty obvious by the question that this is going to be completely out of the realm of experience for most of the teenagers.
