Why doesn't The Church allow women to the priesthood today?

There are a lot of traditions of the Catholic church that they do not see themselves changing at the present time. According to the Bible, the church was established by Jesus who only ordained men and this is something that they would like to continue. It is like a tradition wherein the priests that have to be ordained are all men and nuns should always be women.

The constitution of the church is very intricate. There are some things that they are allowed and not allowed to do. There are some things that they may have changed because of the recent times but allowing women to become priests is not one of them.
