I don't think a male made it.
When I read those words I quite agreed with it. I'm pretty sure everyone hates something about their boobs that was on that list. Maybe you don't, I don't know. So, it's about appreciating your boobs whatever size or shape - 'cause one day you might get breast cancer and need to have them removed. It's saying there is nothing wrong with any of the boobs in the advert even though they are all different.
I believe the boobs make it effective. How could you do a video with those words, without the boobs? It would have a new meaning, if any at all. It's not like we've never seen them before. Most younger kids might act childishly towards it but hey, they're kids and won't understand breast cancer is actually a serious cause. o_o;
Edit: The boobs aren't being shown as sexual objects either... either a man or woman could have made it.
