Hey there, a quick update on some studies I added:
- The doctoral thesis by Jaimie F. Veale from 2011 covers a broad issue of topics, including family concordance for gender variance, a review of twins with gender variance, finger length ratios, handedness, systemising and gender identity outcomes of adults with disorders of sex development and related conditions. The author concludes that the findings “add support for a biological predisposition for gender-variant and gender-typical identities.”
- In a letter to the editor of the “Journal of Clinical and Experimental Medicine” in 2014, Nancy Segal and Milton Diamond write about a case of identical twins who were reared apart (!) and both developed transsexualism: “Genetic effects on transsexuality are strongly indicated by this unique case study.”
- The same Milton Diamond of Hawaii states in the “Women’s Studies Review” in 2012 that genetic factors and hormonal influence in the womb factors are the major causes of transsexualism. These factors then influence the responses of the person to environmental and social factors.
- Witte et al. in “NeuroImage” (2010) write that sex hormones in young adulthood have an organising effect on grey matter in the brain, which is different for male and female hormones.
- Neufang et al. state in “Cerebral Cortex” in 2009 that hormones during puberty affect the volume of grey matter in areas which are associated with sexual maturation.
- Australian researchers Crystal Boza and Kathryn Perry (“International Journal of Transgenderism”, 2014) found that sex reassignment surgery was linked to lower levels of depression.
- Louis J. Gooren reports in 2014 (“Current Opinion in Endocrinology, Diabetes, and Obesity”) that hormone treatment is effective and safe, and that no regrets about changing sex have been found in his study.
- The same Louis Gooren together with Paul Lips reports that hormone treatment in old-age is relatively safe, but requires monitoring for cardiovascular disease, at least for male-to-female transsexuals (“The Journal of Sexual Medicine”, 2014).
- The 2001 honour’s thesis by R. McGrane states that transsexuals are more similar to women than to transvestites, and that gender identity is the underlying factor for gender dysphoria. This finding helps to disprove the autogynephilia hypothesis.
- Milton Diamond and Ernie Govier found in 2007 (“Proceedings of the International Academy for Sex Research”) that the response of male-to-female transsexuals for dichotic listening differs significantly from male controls. Male-to-female transsexuals’ dichotic performance is more similar to women’s than to men’s. This finding is suggestive of some hard-wired differences in brains of transsexuals.
I also improved layout and internal navigation of the reference pages (finally!).
Have a good weekend!
