Abstract
Background: Prenatal exposure to increased androgens has been implicated in both polycystic ovary syndrome
(PCOS) and autism spectrum conditions (ASC), suggesting that PCOS may be increased among women with ASC.
One study suggested elevated steroidopathic symptoms (‘steroidopathy’) in women with ASC. As the symptoms are
not independent, we conducted a latent class analysis (LCA). The objectives of the current study are: (1) to test if
these findings replicate in a larger sample; and (2) to use LCA to uncover affected clusters of women with ASC.
Methods: We tested two groups of women, screened using the Autism Spectrum Quotient - Group 1: n = 415
women with ASC (mean age 36.39 ± 11.98 years); and Group 2: n = 415 controls (mean age 39.96 ± 11.92 years). All
participants completed the Testosterone-related Medical Questionnaire online. A multiple-group LCA was used to
identify differences in latent class structure between women with ASC and controls.
Results: There were significant differences in frequency of steroid-related conditions and symptoms between
women with ASC and controls. A two-class semi-constrained model best fit the data. Based on response patterns,
we identified the classes as ‘Typical’ and ‘Steroidopathic’. The prevalence of the ‘Steroidopathic’ class was significantly
increased within the ASC group (ΔG2 = 15, df =1, P = 0.0001). In particular, we confirmed higher frequencies of epilepsy,
amenorrhea, dysmenorrhea, severe acne, gender dysphoria, and transsexualism, and differences in sexual preference in
women with ASC.
Conclusions: Women with ASC are at increased risk for symptoms and conditions linked to steroids. LCA revealed this
steroidopathy despite the apparent underdiagnosis of PCOS.
