I suspect the only sure way to answer your question would be to stop taking PM for 3 or 4 months, have the blood work done again and see what the levels are. There are so many questions in this part of physiology/medicine, that even endocrinologists can't agree on the right answer. Partly it has to do with redundant feedback mechanisms which operate by different pathways, and partly it's just darn complex.
See this search for what an elevated LH level means in men (primary testicular failure, or primary hypogonadism, but that would be good, right?):

Did your doc seem concerned about testicular failure? Are you worried about it? Your doc didn't test for E2 (estradiol) levels, so it's a little hard to make other than broad guesses. You still have pretty normal T levels, which one would also suspect to be low if you were hypogonadal, so you might be on the verge of testicular failure as indicated by the higher than normal LH which might be necessary for the pituitary to secrete in order maintain normal levels of T. Arghhhh, my brain, my brain.....it hurts!
I would also recommend looking into the potential causes of hypogonadism. However, if we are being totally candid here, I suspect the PM may be causing this so you would have secondary or acquired hypogonadism, which would mean you don't need to worry about some of the more unpleasant causes of primary hypogonadism. Also realize, ideopathic (that's the grown up fancy way of saying we don't know why it's happening) hypogonadism occurs in many men as they age (called late onset hypogonadism; see the wikipedia entry on hypogonadism), so depending on your age, health status, other meds you may be taking, substance abuse issues if any, it could be normal. Then again, it all depends, so it might not be normal.
I don't know the training of a NP. How does it compare to an MD? Does that individual have the training to recognize levels that suggest further diagnostic testing might be needed? You could always shop around for a second opinion if you are really concerned. Just take the lab results and see what they say. Does your doc know you are taking PM? There is a thread that talks extensively about keeping your medical practitioners in the loop, so you don't have to do all the worrying about things like this.
And remember, I am NOT a physician, and I AM making guesses here. By all means, do your research (if only so you will be able to understand your doc much better) but get a professional medical opinion on this.
