Transsexualism and sex-related differences in hemispheric asymmetry.

Sex differences in human brain lateralization are documented by studies on normal subjects, patients with the unilateral brain damage, and individuals with atypical level of hormones. However, there is no agreement as to the specific role of gender in the development of hemispheric asymmetry. This experiment was designed to examine whether gender identity plays an important role in the formation of brain lateralization, as some recent data seem to suggest. A group of subjects showing gender dysphoria (transsexuals) and two groups of control male and female subjects were presented with verbal and visual-spatial tasks. Results show that neither biological sex nor gender identity are sufficient factors to determine the pattern of hemispheric asymmetry.

Sexual activity and temperament in Polish transsexuals.

Two groups of 23 female-to-male and 14 male-to-female transsexuals were compared to a representative sample of Polish controls along following dimensions: (i) temperamental features including reactivity and mobility of nervous processes, as measured by Strelau's Temperament Inventory; and (ii) patterns of sexual activity, measured with Dulko's Questionnaire for Measurement of Transsexualism. Transsexuals were found to resemble respective controls on temperamental dimensions according to their sense of gender identity and not their somatic sex. Male-to-female transsexuals were more similar to control females than to control males and the reverse was true for female-to-male subjects. With respect to forms of sexual activity, transsexuals, particularly the female-to-male, were found to have a relatively versatile erotic life. Both groups experienced more dreams with erotic content than respective controls. However, they also manifested fewer successes at satisfying their erotic needs.

A nonspecific disturbance of the gonadostat in women with transsexualism and isolated hypergonadotropism in the male-to-female disturbance of gender identity.

Principal parameters of gonadostat function were determined in 15 female-to-male (F-M) and 7 male-to-female (M-F) transsexual patients (T), all homosexuals. The data were compared with normal heterosexual controls of the respective sex. Anamnesis revealed prolongation of the menstrual cycles in F-M patients, mainly in those taking previously medication with depot-testosterone. However, also in patients with no previous medication the basal body temperature chart revealed anovulatory cycles (all 4 examined patients). In 8 of 9 patients (82.2%) with no previous medication an elevation of serum testosterone was found (63-600 ng/dl). No disturbances in gonadal functions were found in M-F group (semen analysis), serum testosterone was normal (328-710 ng/dl) except 1 case with reduced testosterone level (200 ng/ml). Both women and men with transsexualism revealed significantly higher mean basal serum concentration of LH in comparisons to controls (F-M: 23.14 +/- 16.16 vs 7.56 +/- 4.23; M-F 15.30 +/- 6.49 vs 5.75 +/- 3.66). No changes in basal serum FSH concentration were present. GnRH test (100 micrograms i.v.) revealed decreased evocability of LH in woman with T and exaggerated LH response in men with T. FSH hyperresponse to GnRH was nonsignificant in F-M and significant in M-F T. It is concluded that F-M transsexualism is associated with nonspecific disturbances of gonadostat since hypergonadotropism coexists with the signs of impaired gonadal function. In M-F T and isolated hypergonadotropism coexisted with specific, increased sensitivity of the pituitary to GnRH.
