“In a study of alcoholism, it was noted that alcoholism is a significant health concern for lesbians, with an incidence rate perhaps three times that of the general population.  The relationships among the development of alcoholism in women, the experience of stigmatization and the complex facets of lesbian identity and lesbian community are explored.  This exploration provides for a more comprehensive and critical analysis of alcoholism in lesbians.  As a phenomenon of women’s health, alcoholism is examined using the perspectives of developmental theory, symbolic interactionism and critical theory.  The author offers insights and implications for health care, research and theory building.”  (Hall, J. M., “Alcoholism in Lesbians:  Developmental, Symbolic Interactionist, and Critical Perspectives,” Health Care for Women International 11(1) (1990):89-107.)

“Yalom et al. (1973) studied 20 16-year-old boys of diabetic mothers, who had received estrogen or progesterone during pregnancy.  These boys showed less heterosexuality and less masculinity than 20 control boys.  Netley and Rovet (1982) showed that among 33 males with 47,XXY syndrome, 24% were nonrighthanded, compared to 10% of a control group. …  In the present study, as well as in Lindesay (1987), only homosexual men were studied.  In Rosenstein and Bigler (1987) and McCormick et al. (1990), both men and women were studied, and in the latter study, a significant increase in lefthandedness (or rather nonrighthandedness) was obtained for women.  This was assumed to be related to higher-than-normal levels of prenatal testosterone levels.  In their results, the increase in lefthandedness in homosexual women (which have lower occurrence than men in the general population) is much larger than that of homosexual men.  It is, therefore, fair to assume that the increase in testosterone, believed to cause both lefthandedness and homosexuality in women, will give a more pronounced effect in women than in men (p. 184).”  (Coates, T. J., Ekstrand, M., and Gotestam, K. O., “Handedness, Dyslexia and Twinning in Homosexual Men,” International Journal of Neuroscience 63(3-4) (1992):179-86.)

“Although numerous researchers have hypothesized a biological factor in the etiology of homosexuality, there is a lack of empirical evidence.  Previous investigations did not focus on behavioral functions of the brain.  Using neuropsychological testing, we found an increased incidence of left-hand preference (defined as non-consistent right-hand preference) in a group of 32 homosexual women.  A trend in the same direction was found in a group of 38 homosexual men.  These results suggest that homosexual orientation has a neurobiological component possibly related to hemispheric functional asymmetry.  The results are consistent with previous reports that (1) prenatal neuroendocrine events are a factor in the development of human sexual orientation and functional brain asymmetries, and (2) the mechanisms associated with homosexual orientation and related neuropsychological characteristics are different between the sexes, i.e., elevated levels of prenatal sex hormones in women and decreased levels in men.”  (Kingstone, E., McCormick, C. M., and Witelson, S. F., “Left-handedness in Homosexual Men and Women:  Neuroendocrine Implications,” Psychoneuroendocrinology 15(1) (1990):69-76.)

“Human homosexual males report more stressors (such as bereavement) during their mother’s pregnancy than controls (Dorner, Schenk, Schmiedel, and Ahrens 1983).”  (S. Baron-Cohen, S. Lutchmaya, and R. Kinickmeyer, Prenatal Testosterone in Mind:  Amniotic Fluid Studies (Massachusetts:  MIT Press, 2004), pp. 11-12.)

“Matched groups of homosexual men, heterosexual men, and heterosexual women (n = 38 per group) were tested on three measures of spatial ability and two measures of fluency that typically reveal sex differences.  For the three spatial tests and one of the fluency tests, the mean performance of homosexual men fell between those of the heterosexual men and women.  The pattern of cognitive skills of homosexual men was different from that of heterosexual men: homosexual men had lower spatial ability relative to fluency.  The cognitive pattern of homosexual men was not significantly different from that of heterosexual women.  In addition, the results suggest that homosexual men classified on the basis of hand preference may form two subgroups that differ in cognitive pattern.  These findings are compatible with the hypothesis that there is a neurobiological factor related to sexual differentiation in the etiology of homosexuality.”  (McCormick, C. M., and Witelson, S. F., “A Cognitive Profile of Homosexual Men Compared to Heterosexual Men and Women,” Psychoneuroendocrinology 16(6) (1991):459-73.)

“The raised incidences of strong left-handedness and of mixed-handedness in homosexual men, as in dyslexics, are mutually consistent under the normal distribution function, as expected by the right shift theory of handedness.  It is argued that atypical laterality in these groups is better described as a ‘reduction of right shift’ than as a ‘left shift.'”  (Annett, M., “Comments on Lindesay:  Laterality Shift in Homosexual Men,” Neuropsychologia 26(2) (1988):341-3.)

“A study of handedness, dyslexia, stuttering and twinning, was included in a study of sexual habits of homosexual men.  A questionnaire was mailed to homosexuals, and 394 forms suitable for data analysis were received.  The results showed an increased rate of lefthand writing (17.5% compared to 8-8.4%), and a clear left shift.  There were increased occurrence of both stuttering (7.1% compared to 1.6%) and reading difficulties (7.9% compared to 1-3%).  The incidence of twins was lower than the population (1.3%).  The results confirm earlier attempts to show a left shift in homosexuals, and support Geschwind’s hypotheses about etiological factors for both lefthandedness and homosexuality.”  (Coates et al., 179-86.)


Phonetic dyslexics (Annett, 1990); stutterers (Corballis, 1981; Bryden, 1994); many Tourette’s sufferers (Shapiro et al., 1972); many gifted athletes, mathematicians, artists, musicians (Deutsch, 1978; Hassler, 1991b; Hassler & Gupta, 1993), and composers (Hassler, 1992); many schizophrenics (Crow et al., 1996); specific alcoholic types (London, 1985) and many obese women are individuals located at the left end of this societal balance that I’ve been describing.  In addition, there are many homosexuals and lesbians firmly positioned in matrifocal social structure displaying high testosterone women and low testosterone men.

Congregating these various excerpts in a single place, I’m hoping to make clear the pattern this particular group exhibits in the context of the thesis I’ve been describing.  There are groups in current society that exhibit neurological, endocrinological and handedness dispositions characteristic of matrifocal social structure and, hypothetically, our recent evolutionary forebears.  Gays and lesbians fit the paradigm.  Gays evidence maturational delay and females evidence acceleration.  In addition, females exhibit higher testosterone levels, males lower levels, and both are coming from high testosterone mothers.

I’d expect that male homosexuals, if they congregate features like those that we hypothesize were common when we were evolving in matrifocal social structures, would be often narcissistic, performance based, highly sexually motivated, often obsessive compulsive, musically inclined and excellent dancers.

I would estimate that lesbians would often feature female traits in our ancient matrifocal archetype.  They would have commanding dispositions, and they would be overweight (high testosterone/high estrogen), extremely discriminating and musically inclined.

I would also predict that gays and lesbians would often have relatives with autism and Asperger’s, with homosexuality not uncommon among the autistic and those with Asperger’s.  Gays and males with autism feature maturational delay; lesbians feature maturational acceleration.

The patterns here seem pretty clear.

    I thought the basic idea of homosexuals more likely to have autistic and Aspergers siblings the same as my own musings. I’m self-diagnosed Aspergers with one of my older brothers being gay. I see it in other similar families. Homosexuality is a product of a form of autism imo.

    My husband and I appear to have both had an oversupply of testosterone in the womb. My fourth digits are longer than my second digits. His fourth are so long, they are almost the same as his third digits. What do you make of this?

    We both have difficulty looking people in the eye, at times– him, moreso than me. I have facial hair on my chin which I pluck or shave. He has a problem with baldness. We both have a problem with anger control and, at times, with aggressive acting out.

    I have never felt like a lesbian, but on the other hand, I’m not a “girlie-girl”. I prefer wearing slacks to wearing skirts and dresses. My husband has said that at times he has felt less than male, and has wished to be a female. But, if he has so much testosterone, how could this be?

    Yes, that was bullshit now I’ve just re-read it.

    P.S I haven’t got Aspergers, just high anxiety etc..

    I’ve always thought there was a link. Often times you find autistic individuals with not-so-normal attractions to objects. Some are even sexually aroused by the object. When I first heard this, I immediately thought about the possibility of homosexuality and autism. As we see a rise in autism, we see a rise in homosexuality. Or this could just be a rise in uncloseted cases. We aren’t sure what causes autism or homosexuality, but when we find one, we should check for similarities.

    Just to clarify, I believe in equality for all and I’d never call homosexuality a disease or mental illness. So long as someone can function in society, then there’s no reason to change them. Also, to back up my opinion, I’m a homosexual male who has been diagnosed by a professional as autistic.

    Imagine the scandal if by curing autism someone accidentally caused a change in sexual orientation.
