A quick update: Impact of sexual orientation, autism

Heya everybody,

I’m happy I found some time to do some updates! Finally ☺

I have added about ten or so new studies, but still have to upload them. I’ll do that soon, hopefully. ☺

A few studies that I found particularly interesting, warrant mentioning here:

One is Impact of Sexual Orientation Identity on Medical Morbidities in Male-to-Female Transgender Patients by Gaither, Awad, et al. (in LGBT Health, 2017). They used a large group of 330 male-to-female transsexual patients to measure sexual orientation (attraction to men, to women or bisexuality) and tried to find a correlation to other medical issues, including psychopathological problems. Their conclusion is that The majority of medical morbidities are not associated with sexual orientation identity. I believe this to be another nail in the coffin of Michael J. Bailey’s autogynephilia hypothesis. Differences were found with regards to depression (female-attracted male-to-female transsexuals suffer more from it) and HIV (male-attracted patients have a higher occurrence rate. Oh, and another interesting result: The share of the three sexual orientation categories was pretty much equal at about one third each.

Two other studies researched the link between transssexualism and autism spectrum disorders. One study (Evaluation of Asperger Syndrome in Youth Presenting to a Gender Dysphoria Clinic by Shumer, Reisner, et al. in LGBT Health, 2016) found a 23 % prevalence of autism spectrum disorders in a sample of 39 gender-dysphoric youth. The other study (Gender Variance Among Youth with Autism Spectrum Disorders: A Retrospective Chart Review by Janssen, Huang and Duncan in Transgender Health, 2016) looked at the issue the other way around, by trying to find gender-dysphoric childrens and adolescents in a large sample of autism-spectrum-disorder diagnosed patients. They found a much higher prevalence of about 5 % for gender dysphoria (in both natal males and natal females) in autism-spectrum-diagnosed patients than the 0.7 % in the control group. I believe this supports the hypothesis by Simon Baron-Cohen that autism is linked to unusual levels of sex hormones during early brain development.

Have a good Sunday evening! Peace and Light ✨
