Men’s Health has listed the loss of morning wood as one of the early signs of erectile dysfunction.
ERECTILE DYSFUNCTION SIGN: YOU HAVEN’T WOKEN UP WITH MORNING WOOD IN A WHILE
Nighttime and early morning erections have nothing to do with feeling aroused: They happen because your brain releases less noradrenaline—a hormone that keeps erections from happening nonstop—during sleep.
Having frequent morning wood is a good thing, since it indicates the blood vessels that allow blood to flow to your penis are healthy, says Dr. Ramin.
If you start noticing that you’re waking up with an erection less often than usual, that could mean that those blood vessels aren’t working as well as they should—making it harder for blood to flow into your penis to become erect, Dr. Ramin says. That means the same issue impeding your morning wood might eventually rear up in the bedroom, when you’re actually trying to get hard.
Now, there’s no magic number that means you could be in trouble. It’s any amount that’s different than your normal that raises the red flag.
