The clinical manifestations of emission are the involuntary ejaculation of semen, at least 2 times a week. This condition usually occurs while sleep, along with dream or no dream. Or sometimes just a few drops of semen ooze out when passing water. In severe cases, semen can be ejaculated involuntarily even while a man is awake. And it is often accompanied with symptoms like dizziness, tinnitus, forgetfulness, palpitations, insomnia, soreness of waist and knee, lassitude, weak urine stream, discomfort and fullness in lower abdomen and genitals, etc. Wet dream is usually triggered by overstrain, excessive use of the brain, too much sexual intercourse, sexual urge induced by what one sees and hears, eating spicy food, and more.
