Can a sleeping disorder cause low T??

[yeahbuddy289]

I have been struggling with fatigue, low energy, low sex drive, weak erections, unable to build muscle/lose fat, depression, and mood swings for a few years now. My testosterone came back in the normal but low range (301ng/dl) and I just met with my general care doctor and he is referring me to an endo. But I want to know if I could possibly have a sleeping disorder of some sort that is causing my low testosterone ? Should I call my doctors office and ask for a sleep study before going to an endo? Stats are 6'2" 220lbs 25 years old.

Would also like to add when I wake up I dont feel rested. But I do not really show any other symptoms of sleep apnea. Sometimes I will yell, scream, punch, and talk in my sleep.
