The Nature Of Human Chorionic Gonadotropin

The Nature of Human Chorionic Gonadotropin

HCG is never found in the human body except during pregnancy and in those rare cases in which a residue of placental tissue continues to grow in the womb in what is known as a chorionic epithelioma. It is never found in the male. The human type of chorionic gonadotrophin is found only during the pregnancy of women. It is produced in enormous quantities, so that during certain phases of her pregnancy a woman may excrete as much as one million International Units per day in her urine – enough to render a million infantile rats precociously mature.

As often happens in medicine, much confusion has been caused by giving HCG its name before its true mode of action was understood. It was entirely overlooked that it has no stimulating effect whatsoever on normally developed and normally functioning sex-glands. No amount of HCG is ever able to increase a normal sex function; it can only improve an abnormal one and in the young hasten the onset of puberty. HCG acts exclusively at a diencephalic level.

HCG no Sex Hormone

It cannot be sufficiently emphasized that HCG is not sex-hormone, that its action is identical in men [&] women. It never virilizes a woman or feminizes a man. It neither makes men grow breasts nor does it interfere with their virility, though where this was deficient it may improve it. It never makes women grow a beard or develop a gruff voice. I have stressed this point only for the sake of my lay readers because, it is our daily experience that when patients hear the word hormone they immediately jump to the conclusion that this must have something to do with the sex- sphere. They are not accustomed as we are, to think thyroid, insulin, cortisone, adrenalin etc, as hormones.

Importance and Potency of HCG

Owing to the fact that HCG has no direct action on any endocrine gland, its enormous importance in pregnancy has been overlooked and its potency underestimated. Though a pregnant woman can produce as much as one million units per day, we find that the injection of only 125 units per day is ample to reduce weight at the rate of roughly one pound per day.
