I've read many of these articles too and it can be very difficult to check what the sources are and whether there is any validity to personal accounts, especially when the authors embrace values that oppose my own (i'm not pro-life, not anti-gay for example).
However, as Acupuncturist says, it is never futile to discuss the possibility that these events might be true. I think that in light of other events of the past, such as this, we have to consider that possibility. Governments and health organization do not tend to come out with human right transgressions until much later after the fact. I believe that the women and men who may be damaged by these practices deserve our attention.
As for judging whether or not a theory is of a conspiratorial nature, I believe that is superfluous. It seems nowadays that any and all suspicion towards the power elite is met with the accusation of being a conspiracy theory. As if there has never been an abuse of power in our history.
When I read articles like these I always consider the possiblity that it may be true. The first thing I want to know is whether there could be any reason why the accused would want to inflict said damage on said group of people. I've done quite a bit of reading about eugenics over the past couple of years and my conclusion is that there is certainly an ideology of a sort of population control that directs the actions of officials and businessmen within the world's power elite. I rely mostly on the words of the elite themselves, because they are not ashamed of making their views public. And that doesn't mean it gets news coverage. But the documents and books are there and available to the public.
There are no 'secret' missions or 'conspiracy theories, it's all out in the open.
The hCG anti-fertility vaccine is being researched at a few different universities, one of them being Uppsala Hospital University, so at least we have determined that the vaccine exists (not sure anyone doubts that one though). But what's interesting is this: they attempted a trial using Swedish women, but it was unsuccessful (they weren't able to attract a large enough number of women, and many of the participants quit after getting serious side-effects).
In India, a much more successful trial was conducted, and according to the words used by a resercher of medical ethics, it was done without informed consent. The women used were already in medical care at the clinics and were told that they would receive preferrential treatment if they participated in the study. They were actually not told that they were partaking in a study, but rather would receive a anti-fertility treatment that was 'safe'. Of course, at the time, there had been no safety studies performed.
Here's the article from Indian Journal of Medical Ethics
