Question:
If semen exits while a person is defecating, is ghusl required?
Answer:
The answer depends on the cause.
If semen comes out without any sexual desire, without arousal, and simply due to physical pressure while passing stool, then ghusl is not required. In such cases it is treated as a medical issue rather than a sexual discharge. Sometimes pressure in the body or certain health conditions can cause this. If it happens occasionally, no issues at all, but, if it happens repeatedly, it is advisable to consult a urologist to check whether there is an underlying medical condition.
However, if the discharge occurs along with sexual pleasure or arousal, then the ruling changes. In that situation the emission is considered sexual, and ghusl becomes obligatory.
So the principle is clear: if it occurs without desire, ghusl is not required. But if it occurs with sexual pleasure, then ghusl is required.
