Morning wood is an informal term for a morning erection, for which the technical medical term is "nocturnal penile tumescence". It means an erection that a man sometimes has while asleep or right after waking up. Men who do not have erectile dysfunction can experience this sensation. It usually happens during Rapid Eye Movement sleep.[1][2] Other slang terms include "morning glory" and "morning tent".
