What is the ruling on a wife going alone to a male psychiatrist and the door being closed between them, with a secretary outside? Is it permissible to disclose marital secrets to him? And what is the ruling on hypnosis sessions?

It is not permissible to leave one's wife alone with a male doctor in a closed room, even if the husband is in the living room of the apartment. This constitutes an unlawful seclusion (khalwa), and its danger is amplified with hypnosis. A private session does not necessitate seclusion, and there is no objection to the husband being present in the room with the doctor. It is forbidden to disclose marital secrets except to the extent necessary for treatment. The general rule is that a woman should be treated by a female, and a man by a male, and it is not permissible to deviate from this arrangement except for a valid reason.
