Assalam-O-Alaikum
Is there a reason why there are no female prophets?
Well there is no evidence that all prophets were male, Allah only says that He sends messengers to every nation [e.g 16:36 And We certainly sent into every nation a messenger,.....] regardless of gender.
But the best woman of all nation [3:42 Behold! the angels said: "O Mary! Allah hath chosen thee and purified thee- chosen thee above the women of all nations.] , Mary (AS) was not a prophet.

said in the hadeeth of Abu Bakrah upon hearing that the Persians had appointed the daughter of Chosroes as their queen, was “No people who appoint a woman as their leader will ever prosper.” (Reported by al-Bukhaari, 13/53).
