That whole idea that IPAs give you man boobs rests on the idea that 8-PN is a phytoestrogen (which it is), but completely ignores that fact that the dosage required to cause problems in humans is unknown. And, there are more likely reasons for “man boobs” (fat) than a hop compound that can’t even be detected in many beers. In addition, lots of plants contain phytoestrogens and the amount we consume of these plants far outweighs the relatively tiny amounts of hop compounds in beer. (In a homebrewed IPA, you are talking about a few ounces of hops in 5 gallons (19 L) of liquid, and most of the plant material is left behind in the kettle.)
IPAs contain a shitload of estrogen mimicking hormones that some people claim give you bitch tits, aka ManBoobs.
Its not really proven, but of you drink a lot of beer and have man boobs, maybe lay off the IPA and switch to tea or whatever.
