That is interesting I never thought of that. Also I just thought about it and I started to take ivermectin Very early in my iinfection. They say it steralizes the worms.That could be why. I just don't get the part about the whole worms being mucous and hair with fecal matter stuck to it or fiber. It looked like an earthworm with a pointy head and you could see the digestive tract. I posted pics of it here. Do they think they come out looking like they do in the text book? The whole thing is just beyond ridiculous. I have lost all trust in the medical field in this country. I only go when I know I need a medication prescribed and 'Im trying to get off all of them because they treat one symptom and cause another illness. They don't look for causes just treat symptoms. None of the doctors wonder why I suddenly have bleeding ulcers in my intestines and stomach. I know why. Hookworms caused them. I wont tell them that because they will think I'm nuts.
