Is ghusl obligatory after semen discharge during sleep? What is the ruling on a small amount of semen discharge? Is it necessary to wash the bedding upon which semen has fallen? Does semen come from both sexes, or only from men? At what age does it discharge, and does its discharge cease? What is the reason for its discharge?

If semen is discharged during sleep, a ritual bath (ghusl (definition)) is obligatory upon waking. This ruling applies to both men and women alike. As for the bedding soiled by semen, it is recommended to wash it if wet, and to rub it if dry. The remaining trace does not harm, as semen is considered pure according to the preponderant opinion. The discharge of semen indicates puberty and usually does not cease unless sexual desire diminishes and carnal appetite decreases in old age.
