One of the stories I linked to on my page, LadyJean, is about the tetanus shots the World Health Organization used in third world countries until pretty recently. The vaccination programs targeted women of child-bearing age, even though that group had no higher incidence of tetanus than other groups. One of the things found in the shots was hCG. From the article:

...when hCG is introduced into the body coupled with a tetanus toxoid carrier, antibodies will be formed not only against tetanus but also against hCG. In this case the body fails to recognize hCG as a friend and will produce anti-hCG antibodies. The antibodies will attack subsequent pregnancies by killing the hCG which naturally sustains a pregnancy; when a woman has sufficient anti-hCG antibodies in her system, she is rendered incapable of maintaining a pregnancy.

So, the women were going in for tetanus shots, and then for the next ten years or so, their pregnancies would spontaneously abort. The World "Health" Organization did that.
