Sex chromosome anomalies, hormones, and sexuality.

Behavioral investigation of men with sex chromosome anomalies has been primarily limited to the study of institutionalized individuals or patient groups. A double-blind controlled investigation of XYY and XXY men found in a birth cohort of 4591 tall men born in Copenhagen gathered sexual information and assessed the role of hormonal determinants on sexual behavior. There were significant differences in several sexual dimensions and in gender role between XYY men and their controls and XXY men and their controls as well as between XYY and XXY men. Although both proband groups differed from each other and from their controls in pituitary gonadal function, there was no evidence that adult hormonal levels mediate the effect of sex chromosome anomalies on male sexuality.

Diabetes mellitus and male sexual function: a controlled study.

There is an extensive clinical literature on the erectile disorders of diabetic men but a paucity of controlled studies that have taken into account the effects of age, concurrent illnesses and medication on sexual function. This investigation was carried out on 40 diabetic men free from other illness or drugs that could affect sexual capacity and 40 age-matched healthy control subjects. Each subject and his female partner underwent semistructured interviews and the men had comprehensive medical evaluations and polygraphic assessment of sleep and nocturnal penile tumescence in the sleep laboratory during three nights. In comparison to control subjects, diabetic patients reported significant decreases in sexual desire, subjective arousal, erectile capacity, coital frequency and sexual satisfaction. The diabetic group also had significant decrements in duration of rapid eye movement sleep and in frequency, duration and degree of nocturnal penile tumescent episodes. There were no differences between Type 1 (insulin-dependent) and Type 2 (non-insulin dependent) diabetic patients in prevalence of sexual problems or in nocturnal tumescent measures. Significant relations were observed between lack of metabolic control, diabetic complications and impaired nocturnal tumescence. Sexually non-dysfunctional diabetic men had significant nocturnal penile tumescence abnormalities. Diabetic men without coital failures may have a subclinical impairment in erectile function which, although of not significant magnitude to interfere with penetration, is reflected in nocturnal penile tumescent measures. This result raises a note of caution in the interpretation of the nocturnal penile tumescence test for the differential diagnosis of diabetic erectile impotence.

Can fetishism occur in transsexuals?

The literature concerning the relationships between transsexualism and transvestism and their association with fetishism is reviewed. Sexual activity, including sexual arousal to women's clothes, is frequently reported in histories of transsexuals. Characteristics are reported of 12 male subjects who have shown sexual arousal to women's clothes and who have a sustained cross-gender identity combined with a desire for a change-of-sex operation. Diagnostic categories alternative to transsexualism for subjects who cross-dress are inadequate to classify at least some of the 12 subjects reported. Restricting the definition of transsexualism so as to exclude those who have shown fetishistic features is considered premature.
