818 µUI/mL reading - A second opinion would be welcome

Hello.

I am a 29 year old male and over the last 2 years, I've been dealing with free falling libido and slow disappearance of my morning erections to the point I don't have them in the morning at all. I had some blood work done in the past and the only thing that stood out was a prolactin reading of 418 µUI/mL but since it was mildly over the limit it was brushed off . Last month I decided to go again into investigations as I've been eating well, sleeping 7-8 hours a day, working out and generally doing quite well and the reading has doubled to 818 µUI/mL. Everything else came back clean, free test, total test etc are all in normal ranges. My question is, is 818 µUI/mL enough to totally ruin my libido and morning erections?

I have already set up a meeting for endocrinology as my urologist told me this is outside his area of expertise but also wanted to get a second opinion here.
