Why are there so many more autistic boys than girls?

BOYGIRL SMALL

Trying to answer questions like these give us the biggest chance at uncovering the real root causes of autism.

By looking at obvious group differences, we can start to deduce what is the cause of this relatively new (ie. 1930s) neurological disorder, and the ongoing explosion of cases.  That is why the recent revelations from the CDC Whistleblower are so important.  We know autism is more common in boys – there is now evidence suggesting a racial difference in incidence.   Let’s start trying to break down why….

It is my personal belief that autism is linked to exposure to mercury and other neurotoxins at critical times of development in susceptible individuals.  I am very happy to stand up and say this, from what I see in my clinical practice, and after the many, many hours I have spent researching the subject.  I also add into the mix my own experiences of mercury exposure, and I am left in very little doubt.

There are 4 times as many autistic boys as girls.
Why?  
The most obvious area to look is testosterone as a risk factor, this being the most stark difference between boys and girls.  Boyd Haley considered this, and discovered that the female hormone oestrogen decreases thimerosal’s toxic effects, whilst the male hormone testosterone greatly increases its toxicity.  The combination of testosterone and thimerisol is exponentially more neurotoxic that either substance on its own.  This very neatly explains the four-to-one ratio of boys to girls that become autistic and the fact that boys represent the vast majority of the severe cases of autism.  

What might be more interesting still, would be to look at testosterone levels in the girls that develop autism.  Are they higher than average?  Are these girls typically more ‘androgynous’ in physique?  This would again lend evidence to a testosterone link.  Either through genetics, or in-utero exposure to toxins, perhaps some females end up with less of the protective oestrogen, and more of the toxic testosterone, making them at higher risk to develop autism.  It would follow that those females at greater risk would be those who have a family history of low oestrogen and high testosterone, or those who are exposed in-utero (e.g. via flu shots with thimerosal to pregnant mothers, or mothers with large amounts of amalgam fillings – especially those with gum disease, which exacerbates the toxic effects of the released mercury).

It has been noted that people with autism have significantly lower levels of glutathione (a compound essential in the detoxification of mercury from the body).  In their investigations, the father-son team Mark and David Geier found that testosterone blocks the body’s ability to make glutathione and that mercury binds to glutathione, thus inactivating whatever stores the body may already have.   So exposure to testosterone and any mercury compound would be a double-whammy.

Some of these theories (and the associated research) really do help us decipher who is at risk of developing autism – so instead of arguing about why it couldn’t be true, let’s perhaps start to look at, and compile a list of plausible risk factors:

  • High number of dental amalgams in the mother (and concomitant gum disease)
  • Flu vaccination of mother during pregnancy
  • genetically high testosterone
  • prematurity (and schedule of vaccination not sufficiently delayed)
  • fertility treatment (there are interesting suggestions regarding feedback mechanisms and high amount of oestrogen, leading to high testosterone)
  • genetic differences in ability to detoxify (glutathione production, MTHFR genes etc).

Unfortunately, no-one tests for risk factors before vaccinations are given.  So I guess you should just suck up the 1/100 (or greater) chance that your child might be ‘susceptible’ to develop autism.   Fingers crossed!

    Hi Anna,
    My name is Annie, I read your post on Facebook – I’m so interested in your kits – I’m a nurse/midwife (doing home and waterbirths) and am passionate about vaccination and the damage it can do – my little girl is vaccine damaged – I had to have the rabies vaccines during the first trimester – it resulted in deafness, auditory processing disorder and anxiety in my daughter. I would so love to detox her from the effects – would we fit into your research criteria or are you looking more for the asd kiddies ? Well well done on the amazing work you do!
    Kind regards
    Annie
