@dralex first of all, doctors confirmed its male pattern baldness so I don't know why you're still debating it.
Second of all, when your hairline has a tip right in the middle and gets recessed on the temples, it creates a v, thus indicating that miniaturization and/or recession is taking place. It's not indicative of how aggressive your hairloss will be, I wasn't implying that, I'm just saying, this is a tell tale sign of male pattern baldness.
Having a widows peak automatically kind of gives you that v look to the hairline so it's obviously an exception.
