It would seem to me from what I undersand of estrogen related fat stores that breast fat would be A2 receptor dense, even more so than the abs, thighs and butt. If that is the case then why are the boobs the first to go when we lose bodyfat???
Nope. Breast tissue has negligible alpha-2 adrenoreceptors. This is prolly one of the reasons that fat is easier to lose from your breasts than from your thighs and butt.
progesterone is more responsible for breast size (though both are involved).. though agree with MS. in general lower A2 concentrations in WOMEN's chest (at least compared to men with pectoral femization).. there are other factors in breast size (as the glandular "growth" does make up a considerable portion (and is a big factor in "firmness")
