If the penis is in an erect state, the glans is usually hard. However, the glans is integrated with the urethral spongiosa, and since the urethral spongiosa wraps around the urethra and forms the glans and urethral orifice in front, it has a different anatomy from the two penile spongiosa, and is not as hard as the penile spongiosa when erect, but is slightly harder. However, if the glans is not hard, it is likely that the problem is caused by congestive dysfunction. It is best to have further examination to clarify the specific cause before choosing targeted medication for symptomatic treatment.
