What to ask for in a bloodtest?

I’m getting bloodwork, specifically for libido and sexual health related.

Right now, my doctor only assigned me to test testosterone, but I would appreciate other things I need to look for to avoid needing doing it again, and to get the most insight.

@BoostYourBiology I’d appreciate some help on this matter. Is there a sticky or FAQ about this? I want to get all the needed data to work with, particularly for sexual health.

Thanks ahead!
