Transsexuals’ life satisfaction after gender transformation operations

Title: Transsexuals’ life satisfaction after gender transformation operations

Link: http://www.ncbi.nlm.nih.gov/pubmed/16437228

Summary: (abstract)

More and more frequently, the registration of life satisfaction is being used to evaluate different medical treatments. So far, there have been only few such surveys on transsexuals (TS). Therefore, the aim of this study was to evaluate the general and the health-related life satisfaction of transsexuals after gender transformation operations.

PATIENTS AND METHODS:

Forty patients took part in this German cross-sectional study. The Questions on Life Satisfaction Module (FLZ) and free questions on different aspects of the new gender identity were used as measuring instruments.

RESULTS:

Of the TS studied, 85-95% were “very satisfied” or “satisfied” with the results of their gender transformation operation in respect to gender identity. The TS were significantly less satisfied (P>0.001) in overall “general life satisfaction” than the general population. In overall FLZ scores for “health-related life satisfaction”, no differences were seen.

CONCLUSION:

These data indicate a discrepancy between subjective satisfaction with new gender identity and current life situation, and they identify problems with life satisfaction.

The outcome of sex reassignment surgery in Belgrade: 32 patients of both sexes

Title: The outcome of sex reassignment surgery in Belgrade: 32 patients of both sexes

Link: http://www.springerlink.com/content/507122v1j82t0711/

Summary: (abstract)

Several aspects of the quality of life after sex reassignment surgery in 32 transsexuals of both sexes (22 men, 10 women) were examined. The Belgrade Team for Gender Identity Disorders designed a standardized questionnaire for this purpose. The follow-up period after operation was from 6 months to 4 years, and four aspects of the quality of life were examined: attitude towards the patients’ own body, relationships with other people, sexual activity, and occupational functioning. In most transsexuals, the quality of life was improved after surgery inasmuch as these four aspects are concerned. Only a few transsexuals were not satisfied with their life after surgery.

Factors Associated with Satisfaction or Regret Following Male-to-Female Sex Reassignment Surgery

Title: Factors Associated with Satisfaction or Regret Following Male-to-Female Sex Reassignment Surgery

Link: http://www.springerlink.com/content/g40k461746677054/

Summary: (abstract)

This study examined factors associated with satisfaction or regret following sex reassignment surgery (SRS) in 232 male-to-female transsexuals operated on between 1994 and 2000 by one surgeon using a consistent technique. Participants, all of whom were at least 1-year postoperative, completed a written questionnaire concerning their experiences and attitudes. Participants reported overwhelmingly that they were happy with their SRS results and that SRS had greatly improved the quality of their lives. None reported outright regret and only a few expressed even occasional regret. Dissatisfaction was most strongly associated with unsatisfactory physical and functional results of surgery. Most indicators of transsexual typology, such as age at surgery, previous marriage or parenthood, and sexual orientation, were not significantly associated with subjective outcomes. Compliance with minimum eligibility requirements for SRS specified by the Harry Benjamin International Gender Dysphoria Association was not associated with more favorable subjective outcomes. The physical results of SRS may be more important than preoperative factors such as transsexual typology or compliance with established treatment regimens in predicting postoperative satisfaction or regret.

Male-to-Female Transsexuals Have Female Neuron Numbers in a Limbic Nucleus

Title: Male-to-Female Transsexuals Have Female Neuron Numbers in a Limbic Nucleus

Summary: (abstract)

Transsexuals experience themselves as being of the opposite sex, despite having the biological characteristics of one sex. A crucial question resulting from a previous brain study in male-to-female transsexuals was whether the reported difference according to gender identity in the central part of the bed nucleus of the stria terminalis (BSTc) was based on a neuronal difference in the BSTc itself or just a reflection of a difference in vasoactive intestinal polypeptide innervation from the amygdala, which was used as a marker. Therefore, we determined in 42 subjects the number of somatostatin-expressing neurons in the BSTc in relation to sex, sexual orientation, gender identity, and past or present hormonal status. Regardless of sexual orientation, men had almost twice as many somatostatin neurons as women (P < 0.006). The number of neurons in the BSTc of male-to-female transsexuals was similar to that of the females (P = 0.83). In contrast, the neuron number of a female-to-male transsexual was found to be in the male range. Hormone treatment or sex hormone level variations in adulthood did not seem to have influenced BSTc neuron numbers. The present findings of somatostatin neuronal sex differences in the BSTc and its sex reversal in the transsexual brain clearly support the paradigm that in transsexuals sexual differentiation of the brain and genitals may go into opposite directions and point to a neurobiological basis of gender identity disorder.

A sex difference in the human brain and its relation to transsexuality

Title: A sex difference in the human brain and its relation to transsexuality

Link: http://www.nature.com/nature/journal/v378/n6552/abs/378068a0.html

Summary:

TRANSSEXUALS have the strong feeling, often from childhood onwards, of having been born the wrong sex. The possible psycho-genie or biological aetiology of transsexuality has been the subject of debate for many years1,2. Here we show that the volume of the central subdivision of the bed nucleus of the stria terminalis (BSTc), a brain area that is essential for sexual behaviour3,4, is larger in men than in women. A female-sized BSTc was found in male-to-female transsexuals. The size of the BSTc was not influenced by sex hormones in adulthood and was independent of sexual orientation. Our study is the first to show a female brain structure in genetically male transsexuals and supports the hypothesis that gender identity develops as a result of an interaction between the developing brain and sex hormones5,6.

Phantom Penises in Transexuals

Title: Phantom Penises in Transexuals

Linkhttp://www.ingentaconnect.com/content/imp/jcs/2008/00000015/00000001/art00001

Summary: (abstract)

How the brain constructs one’s inner sense of gender identity is poorly understood. On the other hand, the phenomenon of phantom sensations– the feeling of still having a body-part after amputation–has been much studied. Around 60% of men experience a phantom penis post-penectomy. As transsexuals report a mismatch between their inner gender identity and that of their body, we wondered what could be learnt from this regarding innate gender-specific body image. We surveyed male-to-female transsexuals regarding the incidence of phantoms post-gender reassignment surgery. Additionally, we asked female-to-male transsexuals if they had ever had the sensation of having a penis when there was not one physically there. In post-operative male-to-female transsexuals the incidence of phantom penises was significantly reduced at 30%. Remarkably, over 60% of female-to-male transsexuals also reported phantom penises. We explain the absence/presence of phantoms here by postulating a mis-match between the brain’s hardwired gender-specific body image and the external somatic gender. Further studies along these lines may provide penetrating insights into the question of how nature and nurture interact to produce our brain-based body image.
