No Morning Wood After A Rough Period Of Sleep Depravity

Dear Doctors,

For some time I have known that I do not have morning erections or that I have rare and rather weak erections. But let’s say that my life is quite unregulated and that I go to bed on average at 5 in the morning, usually because I study until late… So it happens that I always wake up tired and never feel completely rested; when instead I go to sleep earlier and I am calm, the situation is a little better, I feel more rested and I feel an erection in the morning. In any case: is it serious not to have morning erections? During masturbation or in any case if I touch my penis it becomes hard. Do I have to worry? In any case, I will submit the analysis to the andrologist to whom I will better ask for a specific opinion on the thing. Thanks in advance to those who want to answer.
