Homosexual transsexual,[1] synonymous with androphilic transsexual, is a term used by various sexologists, psychologists, and psychiatrists to describe trans women who are exclusively attracted to men, and less often trans men who are attracted to women. The term has become controversial. The concept of taxonomically categorizing trans women by sexual orientation originated with Magnus Hirschfeld in 1923, and was further posited by Harry Benjamin in 1966 as a component of the Benjamin scale. The specific term homosexual transsexual was coined by Kurt Freund in 1973, and used from 1982 onward by him and others, notably Ray Blanchard, as part of a two-type taxonomy of male-to-female transsexuality. This taxonomy has subsequently evolved into, and is in the present day referred to, as Blanchard's transsexualism typology.
In the DSM III, published in 1980, transsexualism was to be diagnosed and the sexual orientation of a transsexual specified using the terms homosexual, heterosexual, asexual, or unspecified. This convention had its origins in the taxonomic work of researchers like Hirschfeld, Benjamin, and Freund and the fact that grouping trans women by sexual orientation reveals important qualitative and statistical differences between them, and that said differences have been maintained by various researchers as indicative or suggestive of multiple, distinct etiologies. The term homosexual transsexual has since been used in publications by a variety of academics, including Benjamin, Freund, Blanchard, and Anne Lawrence, as well as J. Michael Bailey and James Cantor, among others.
The term homosexual transsexual has been criticized from a lexical standpoint by Benjamin, Bruce Bagemihl, and John Bancroft (though supported conceptually by the former two), as being confusing, as well as insensitive to the gender identities of those whom it is intended to describe. The alternatives androphilic and gynephilic have been proposed by Milton Diamond as descriptors for sexual orientation that do not make assumptions about the sex or gender identity of the person being described. Terms such as androphilia and gynephilia are sometimes used instead of, or concurrently with, homosexual, heterosexual, or non-homosexual in current research, such as research which has used the Modified Androphilia Scale to assess the attraction to men of a given trans woman. S. J. Whang contended in 2004 that the term homosexual transsexual is "archaic". Though the term transsexuality was removed as a mental disorder from the DSM-IV and was replaced with gender identity disorder as a diagnostic label, attraction to males, females, both, or neither remains specified in the DSM IV-TR.
Most research of the research on homosexual transsexuality has been conducted on trans women. They are usually socioeconomically disadvantaged, born later in a series of brothers, are unlikely to display cross-gender fetishism or autogynephilia, and come out at a younger age than non-homosexual trans women. Relatively little research has been done on gender variance in assigned women and the prevalence of female-to-male gender identity disorder (GID) is less than that of male-to-female GID.
Development of the concept
The term homosexual transsexual was defined by Kurt Freund in 1974, and is used by various sexologists and psychiatrists to describe trans women who are attracted to men,[2][3] though occasionally they use it to describe trans men who are attracted to women.[4] The concept of a taxonomy based on transsexual sexuality was first proposed by physician Magnus Hirschfeld in 1922,[5][6] and codified by endocrinologist Harry Benjamin in the Benjamin Scale in 1966,[7][8] which was published in the influential book "The Transsexual Phenomenon".[7] Benjamin wrote that researchers of his day thought that attraction to men, as a woman was the factor that distinguished a transvestite from a transsexual.[7] "The transvestite - they say - is a man, feels himself to be one, is heterosexual, and merely wants to dress as a woman. The transsexual feels himself to be a woman ("trapped in a man’s body") and is attracted to men."(Benjamin 1966).[7]
Homosexuality was removed as a mental disorder from the DSM-II, the diagnostic manual published by the American Psychiatric Association, the most widely used diagnostic manual worldwide.[9] Ego-dystonic homosexuality was retained as a diagnosis for those who are caused distress by their sexual orientation.[9]
In 1980 in the DSM III, a new diagnosis was introduced, that of "302.5 Transsexualism" under "Other Psychosexual Disorders". This was an attempt to provide a diagnostic category for gender identity disorders; the others included were "302.3 Transvestism" and "302.8 Fetishism".[10] The diagnostic category, "transsexualism", was for gender dysphoric individuals who demonstrated at least two years of continuous interest in transforming their physical and social gender status.[11] The subtypes were 1. asexual, 2. homosexual (same anatomic sex), 3. heterosexual (other anatomic sex) and 0. unspecified.[10]
Physician and sexologist Kurt Freund proposed two types of cross-gender identity in 1982, based on his observation that gender identity disorder is different for homosexual males and heterosexual males.[12] Subsequently, this term appeared in the DSM-III-R, but not in the DSM IV in which gender identity disorder replaced transsexualism.[13] Sexologists quantitatively measure sexual orientation using psychological personality test or they rely on self reports. Blanchard and Freund used the Masculine Identity in Females (MGI), and the Modified Androphilia Scale.[14] Homosexual transsexuals averaged a Kinsey scale measurement of 5–6 or a 9.86 ± 2.37 on the Modified Androphilia Scale.[15][16] S.J. Whang wrote in 2004 that homosexual transsexual appeared in the DSM III-R, and that he considered it archaic (see next section).[13]
Terminological debate
The concept that transsexuals with homosexual and non-homosexual sexual orientations are etiologically different has a long history in this field.[13][17][18][19] However the terms used have not always been agreed on.[17][18] In recent years scientists working on the topic have criticized the practice of categorizing transsexuals by sexual orientation and sex at birth.[17][18][20] In the words of Benjamin, male-to-female transsexuals can only be homosexual if anatomy alone is considered, and the psyche of MTF transsexuals is ignored. According to him after SRS calling a male-to-female transsexual homosexual is pedantic.[21] One must bear in mind that when Benjamin was writing, transsexual implied male-to-female, and attracted to men.[7] For a time in the 1980s terms which SJ Wahng describes as homosexual transsexual were in the DSM-III-R (transsexual,homosexual subtype)[13][22] Tamara Shefer said that the DSM-IV and DSM-IV-TR stipulate that the sex a transsexual is attracted to be specified as "attracted to males, females, both or neither".[22]
Others, such as biologist and linguist Bruce Bagemihl, agree with what Benjamin wrote about the use of this term.[17] Bagemihl wrote that this terminology makes it easy to say transsexuals are really homosexual males seeking to escape from stigma.[17] Sexologist Jim Weinrich opined that sexologist Ray Blanchard looked for information to support his theory instead of letting the evidence guide his theorizing, by using "a series of clever questionnaires and plethysmogaphic studies."[23] Weinrich said that Blanchard asserted all female-to-male transsexuals were "woman loving".[23] Leavitt and Berger criticized the term in 1990, saying that it was "both confusing and controversial among males seeking sex reassignment."[16][24] Critics argue that the term "homosexual transsexual" is "heterosexist",[17] "archaic",[13] and demeaning because it labels people by sex assigned at birth instead of their gender identity.[25] Benjamin, Leavitt, and Berger have all used the term in their own work.[7][16] Sexologist John Bancroft also expressed regret for having used this terminology, which was standard when he used it, to refer to transsexual women.[26] He says that he now tries to choose his words more sensitively.[26]
Alternative terms
Professor of anatomy and reproductive biology, Milton Diamond (1990, 2002) proposed the use of the terms androphilic and gynephilic as alternatives to homosexual and heterosexual. Diamond wrote that the terms homosexual and heterosexual are confusing as applied to transsexual persons because it is not instantly clear whether they reference the pre- or post-transition state.[19][27] S.J. Wahng said in 2004 that the diagnosis homosexual transsexual is archaic and conflates homosexuality with transsexuality.[13]
Sexological research has been done using these alternative terms by researchers such as Sandra L. Johnson (1990).[28] In research done by Blanchard in 1985, and Leavitt they used a psychological test called the "modified androphilia scale" to assess whether a transsexual was homosexual or not.[5][16]
Transsexual community reaction
According to Leavitt and Berger, "transsexuals, as a group, vehemently oppose the label and its pejorative baggage."[16] Trans woman Andrea James has called the term "inaccurate and offensive,"[29] and trans man Aaron Devor wrote, "If what we really mean to say is attracted to males, then say 'attracted to males' or androphilic... I see absolutely no reason to continue with language that people find offensive when there is perfectly serviceable, in fact better, language that is not offensive."[30]
Description
Androphilic male-to-female transsexuals
Sexual activity
Building on work by Freund, Frank Leavitt and Jack C. Berger in 1990 further categorized homosexual transsexuals by three patterns of sexual activity in how they used their penis.[16] In their study 44% were sexually inactive, 19% avoided use of the penis during sex, and 37% derived pleasure from using the penis during sex. The groups showed varying levels of masculinity and emotional disturbance in development.[16] Leavitt and Berger found that transsexuals in the avoidant group are different from those in the other two groups. They fit the description of the "nuclear transsexual".[16] They had a strong cross gender identification, wanted female anatomy, had never married and little to no sexual activity with females.[16] Of all the subgroups this group had the least comorbid psychopathology.[16] The transsexuals in the pleasure group behaved sexually in ways that were "classically homosexual".[16] They were more likely than those in the avoidant group to have had sexual experience with females.[16] They also rated higher on a test of general fetishism.[16] Other than this, transsexuals in the pleasure group were similar to the description of a "nuclear transsexual".[16] They found that transsexuals in the inactive group had characteristics which most differed from that of the "nuclear transsexual",[16] such as strong heterosexual orientations (as determined from psychological testing), and fetish histories. "The pattern exhibited generally conforms to that exhibited by heterosexual transsexuals."[16] The inactive group was found to share little with the other groups of transsexuals other than a stated sexual interest in males.[16] Leavitt and Berger also mentioned studies by Blanchard which suggest that heterosexual transsexuals will adjust their life stories to ensure that they get sex reassignment surgery.(Leavitt 1990)[16]
In The Man Who Would Be Queen, J. Michael Bailey (2003) wrote that the homosexual transsexuals he studied are comfortable with prostitution,[31] and that they have a masculine sexual appetite, but are attracted to men.[31] He reviewed evidence for a taxonomy according to which there are two forms of transsexualism in males, one that is an extreme type of homosexuality and one that is an expression of a paraphilia known as autogynephilia. In The Transsexual Phenomenon (1966), Harry Benjamin writes that "Other transsexuals find prostitution a useful profession for emotional as well as practical reasons..."[7]:50–51 Benjamin goes on to say "How much more can his femininity be reaffirmed than by again and again attracting normal, heterosexual, and unsuspecting men and even being paid for rendering sex service as a woman?"[7]
Socioeconomic factors
Researchers have recently found several demographic features that homosexual transsexuals tend to have in common.[32][33] Ken Zucker(2002) and Yolanda Smith (2005) independently found that homosexual transsexuals are of lower average IQ,[34] social class, and age. They were on average in their mid-teens to mid-20s when they reported to a gender clinic for sex reassignment.[34][35] The homosexual transsexuals are more likely to have recent immigrant status, non-intact families, non-Caucasian race, and childhood behavior problems).[32] Bailey found that most homosexual transsexuals learn to live on the streets, resorting to prostitution, or shoplifting.[31]
D.F. MacFarlane studied transsexuals in Australia and New Zealand.[33] MacFarlane found that in New Zealand that 90% of the homosexual transsexual prostitutes were Māori,[33] an ethnic group who are only 9% of the overall population.[33] In The Man Who Would Be Queen J. Michael Bailey writes that about 60% of homosexual transsexuals he studied in Chicago were Latina or black;[31] in his studies of gay males only 20% were non-white.(Bailey 2003)[31] Bailey quoted the opinions of two of his subjects who attributed the difference to genetics, or inflexible gender roles in their respective cultures.[31] MacFarlane similarly concluded that culture influenced the number of Māori homosexual transsexuals he observed.[33]
Fraternal birth order effect
Recent research on the causes of homosexual transsexualism, transsexualism, and homosexuality overlap to a large degree.[36][37][38] The etiology of transsexualism concerns the causes of transsexuality in general, including the theory that transsexualism is caused by differences in specific areas of the brain, while relationships between biology and sexual orientation have been studied in depth as possible causes of homosexuality.
Blanchard (1996) and Zucker (2007) came to the general conclusion that birth order has some influence over sexual orientation in biological males in general, and homosexual male-to-female transsexuals in specific.[36][37][38] This phenomenon is called the "fraternal birth order effect".[37] In 2000 Richard Green wrote "Homosexual male-to-female transsexuals have a later than expected birth order and more older brothers than other subgroups of male-to-female transsexuals. Each older brother increases the odds that a male transsexual is homosexual by 40%."[38] Green did not find a higher incidence of homosexuality in the younger brothers of homosexual transsexuals.
Zucker and Blanchard wrote that studies have consistently supported the "fraternal birth order effect" that homosexual transsexuals have more brothers than sisters and are born later in birth order. In contrast, in their study using an Asian sample they found that the transsexual men had significantly more sisters than controls.[37] Zucker attributes this to the preference for males in Korean society causing parents to stop having children once they have a boy.[37] Therefore, all male children are less likely to have older brothers and hence no fraternal birth order effect is observed.[37] According to Bailey's interpretation of Blanchard's theory the causes of homosexual transsexuality are extreme examples of the causes of homosexuality in males.[31]
Use in Blanchard's typology
Sexologist Ray Blanchard defined this category in his research, based on testing or self-report, and asserted based on his research that self-report is not always reliable.[15][16][39] Morgan (1978), Blanchard (1985), Lawrence (2005) and other researchers have asserted that many "non-homosexual" transsexuals systematically distort their life stories because "non-homosexuals" were often screened out as candidates for surgery[24] and because some see "homosexual transsexual" as a more socially desirable diagnosis. According to Blanchard (1985, 1987) key characteristics include conspicuous cross-gender behavior from childhood through adulthood, and a "homosexual" sexual orientation. Blanchard also says that non-homosexual transsexual women (as well as all other non-homosexual male gender dysphorics) have a condition called autogynephilia and are aroused by the idea or image of themselves as women.[40] Blanchard (1987) found in his studies that homosexual transsexuals were younger when applying for sex reassignment, reported a stronger cross-gender identity in childhood, had a more convincing cross-gender appearance, and functioned psychologically better than "non-homosexual" transsexuals.[40] A lower percentage of the homosexual transsexuals reported being (or having been) married and sexually aroused while cross-dressing.[34] Studies have variously found that between 10% and 36% of homosexual transsexuals report a history of sexual arousal to cross dressing. Bentler (1976) found 23%, while Freund (1982) reported 31%.[12][16][41][42]
Previous taxonomies, or systems of categorization, used the terms "classic transsexual" or "true transsexual," terms once used in differential diagnoses.[43] Blanchard (1995) also said homosexual transsexuals were comparatively shorter and lighter in proportion to their height than non-homosexuals.[44] Independent research done by Johnson (1990) and Smith (2005) concur with most of Blanchard's observations.[28][34] Smith did not find a significant difference in height-weight ratio.[34] Subsequent research has found only partial support of Smith's findings.[45] Johson's 1990 work used the alternative term "androphilic transsexual", Johson wrote that there was a correlation between social adjustment to the new gender role and androphilia.[28]
Gynephilic female-to-male transsexuals
In 2000 Meredith L. Chivers and Bailey wrote "Transsexualism in genetic females has previously been thought to occur predominantly in homosexual (gynephilic) women." According to them Blanchard reported in 1987 that only 1 in 72 female-to-male transsexuals he saw at his clinic were primarily attracted to men. They write that these individuals were so uncommon that some researchers thought that androphilic female-to-male transsexuals did not exist or they were misdiagnosed them as homosexual transsexuals, attracted to women. Relatively few studies have examined childhood gender variance in biological females.[4]
In the 2005 study by Smith and van Goozen, their findings in regards to female-to-male transsexuals were different from their findings for male-to-female transsexuals.[34] Smith and van Goozen's study included 52 female-to-male transsexuals, who were categorized as either homosexual or non-homosexual. Smith concluded that female-to-male transsexuals, regardless of sexual orientation, reported more GID symptoms in childhood, and a stronger sense of gender dysphoria. Smith wrote that she found some differences between homosexual and non-homosexual female-to-male transsexuals. Smith says that non-homosexual female-to-males reported more gender dysphoria than any group in her study. Smith says "It is of interest, though, that a few female-to-male transsexuals reported to have been sexually aroused in adolescence when dressing in male clothes, as this has never been reported before."[34]
MRI studies and neurological differences
The concept that androphilic male-to-female transsexualism is related to homosexuality in masculine homosexual males has been tested by MRI studies.[46][47] These studies have been interpreted as supporting Blanchard's transsexualism typology.[47] These studies show neurological differences between homosexual transsexuals and controls as well as differences between homosexual and non-homosexual transsexuals.[47]
A more precise recent study looked at the brains of homosexual aspiring transsexual males and females who reported to a gender clinic who had also not had any hormonal treatments.[46] The question the research wished to address was the existence of any differences between transsexuals and non-transsexual brains. Wishing to avoid clouding the issue with a sample of mixed sexual orientations given Blanchard's theory was their stated reason for selecting homosexual transsexuals. This study also controlled for possible influence of external hormones by looking at subjects who had not taken any yet.[46] The study found the following in its sample of homosexual transsexuals :
We found that transsexual subjects did not differ significantly from controls sharing their gender identity but were different from those sharing their biological gender in their regional GM volume of several brain areas, including the left and right precentral gyri, the left postcentral gyrus (including the somatosensory cortex and the primary motor cortex), the left posterior cingulate, precueneus and calcarinus, the right cuneus, the right fusiform, lingual, middle and inferior occipital, and inferior temporal gyri. Additionally, we also found areas in the cerebellum and in the left angular gyrus and left inferior parietal lobule that showed significant structural difference between transgender subjects and controls, independent from their biological gender.[46]
