Is it permissible to perform a hymen repair surgery by a female doctor to avoid marital problems, knowing that the fiancé is aware of the previous relationship?

Looking at the major private parts (awrat) is only permissible out of necessity. It is permissible to perform a hymen repair surgery for a chaste woman whose hymen was ruptured by a fall or similar cause, if she fears harm such as being beaten or being shunned by suitors, as this need is considered akin to a necessity. This ruling applies to a virgin who did not lose her virginity due to a forbidden act or marriage; otherwise, it is not permissible if no harm results from it. The necessity that permits the forbidden is constituted by the threat of severe beating, prolonged imprisonment, destruction of property, or similar acts that affect a rational person. Coercion varies according to individuals and circumstances.
