While Title IX ensures that in principal, I think there are indeed some differences between a club having a program that invites both girls and boys to play and a club that actively takes developmental differences of boys and girls in account to provide the best programs for each.
There are of course exceptions as there are some girls that don't mind playing with boys, but anyone who has coached both boys and girls at the younger age groups has spotted some of the differences. Girls develop teamwork and tactical skills earlier than boys, generally speaking, while boys seem to have the early edge on aggressive physical play and individual skill.
For this reason, an interesting thing happens when you take your 8 or 9 year old daughter out to a co-ed event such as a camp, clinic or scrimmage. With a few noted exceptions, from my experience most girls prefer not to play with a rowdy group of boys at that age, most certainly not if they are the only girl in the group.
