Does the discharge of fluid after a wet dream involving intercourse during a Ramadan day necessitate breaking the fast, and is the fluid considered maniyy or madhiy?

If a fluid (whether seminal fluid or pre-seminal fluid) is discharged due to thought and imagination, this does not affect the validity of the fast, nor does it necessitate expiation. However, the discharge of seminal fluid necessitates ghusl (definition) (ritual bath), while pre-seminal fluid does not, though it does require washing the private parts and purifying whatever it has touched. A Muslim woman should avoid such thoughts, as they may lead to the arousal of desire or the commission of forbidden acts. She should seek refuge in Allah from Satan, recite Ayat al-Kursi, and the remembrances before sleep.
