Yes and no. The presence and absence of morning wood is not. Changes in EQ from a morning erection is a PI, such as if you normally have a soft morning erection but start getting rock hard ones, or the other way around.

Though even then, it's not an important PI to even watch, let alone pay attention to, since we have no physical or mental control over nocturnal erections. They're nothing more than a bladder control method and a normal thing the body does every 30 minute or so during sleep.
