Are male or female Akitas more aggressive?

I'm curious to know, when it comes to Akita dogs, do males or females tend to display more aggressive behavior? Is there any scientific evidence or studies that support one gender being more prone to aggression than the other? Additionally, are there any specific factors that may contribute to the aggression levels in either gender, such as breeding, training, or socialization? It would be great to get a comprehensive understanding of this topic from a professional perspective.
