Hi boobynewbie89, it all depends what they contain, i am male and i have been taking Bountifull breast pills for my NBE they are a form of Bovine overy and they make your body produce estrogen, i know they are effective for men and women and are aimed at both sexes. I think most worth while breast pills do work for both, but there are so many bad ones that dont work so be carefull hun, all the info you need is on here, and if you need any advice or help please message me or one of the other members, good luck hun.
Hugs Cheryl xxxx
