An update on the hypothesis that one cause of autism is high intrauterine levels of testosterone of maternal origin

James, William H.·2014·Journal of Theoretical Biology

Abstract

Baron-Cohen's hypothesis that autism is caused by exposure to high intrauterine testosterone levels is considered in the context of (1) my hormonal hypothesis of sex ratio and (2) the notion of multifactorial inheritance. This yields the suggestions that (1) female cases of autism may be the product of (high genetic loading+moderate environmental exposure) and male cases of (high environmental exposure+moderate genetic loading), (2) one environmental agent is intrauterine testosterone and (3) the mother is the major source of that testosterone. These suggestions may help to explain most of the major established epidemiological risk factors for autism. These include various forms of pathology associated with psychological and/or physical stress. Stress of many sorts promotes the secretion of adrenal androgens in women. The three suggestions above may also explain some recently described features of autism including the psychological, behavioural and neuroanatomical differences between male and female cases.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Elevated prenatal androgens have been strongly associated with ASD risk for more than a decade.

    “For example, elevated prenatal androgens have been strongly associated with ASD risk for more than a decade (26–35) leading some to hypothesize that EDCs that alter androgen action may be contributory.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
