"The reason fertility patients don't take oral hCG but inject it instead is because it doesn't work. Your body doesn't absorb the proteins in hCG when taken orally. An article in the July 2008 "Journal of Pharmaceutical Sciences" by researchers from the University of Louisville pointed out that proteins, which includes hCG, break down and are not well absorbed when given orally. Since supposedly just the "essence" of the drug remains in homeopathic medicine, this offers supporters of the diet an easy out as to why oral hCG doesn't show up on blood tests."
"No studies on the efficacy of oral hCG are available; evidence of its effectiveness is strictly anecdotal."
