Your body will make its own cholesterol. See: http://www.indstate.edu/thcme/mwking/cholesterol.html If inadequate amounts of fat or cholesterol are consumed, such as in anorexics as you mention, sexual development can be arrested. For example, anorexic girls will be too thin to support menstruation, or to develop secondary sex characteristics such as breasts. This is not necessarily because of the inability to manufacture steroid hormones though, since the hormones are fat soluble, some fat is necessary for the hormones to be stored appropriately. Also, when the body is starving there are a lot of "feedback" systems that tell the body not to invest in anything non essential until conditions get better. If the person is past puberty, the sex characteristics wont be lost, other than fat stores being used up. Erin Cram, Moderator MadSci Network
