What is the legal ruling regarding the marriage of a man who later discovered that his wife is a man, knowing that he resides in Belgium?

If you contract marriage with a woman and then it becomes apparent that she has a male organ, then either she is a problematic hermaphrodite (khuntha mushkil) whose masculinity or femininity is not clear, and in this case, the marriage is invalid. Or she is a non-problematic hermaphrodite (khuntha ghair mushkil), like a woman who has a male organ, and in this case, you have the right to annul this marriage.
