Is male medical castration permissible if a wife has refused intimacy for a year? I fear divorce and losing my son but feel unloved and lacking in confidence. What are my options?
Bismihi ta'āla
No, it is not permissible.
If wife refuses intimacy, this is haram for her, she become nāshizah, and it is grounds for divorce, if she persists.
Why would you lose your son. Sharing custody, and being civil about it is very important and to the benefit of both sides.
Marriage counselling and mediation is also very important.
And Allah knows best
