Yeah, but they would need to email/fax a copy of your passport to make this change:
Name, phone number, email, gender, passport/ID card number.

Address can be changed online, but you need to add a new address, then set the new one as the default before you can remove the old one.

If you're curious for some reason my account says I'm a female as well, but I've never had any issues with service. They always address me correctly.
