I think I read somewhere (a while ago) that women are more likely to seek treatment for any kind of mental health issue than men are -- so perhaps these pharmaceutical companies are playing off that? (Target marketing.) Also -- and this is just a guess -- maybe women are more likely to develop bipolar disorder than men are. Or, these companies may be playing off women's emotions, or some combination of all three.

Nevertheless, I agree that they should target men too. Seems rather one sided to only target women, IMO. But most pharmaceutical companies are corrupt and will try their best to make as much money as possible, so maybe they don't care about men (as mean as that sounds).
