“…Sexual orientation may also, however, be linked to handedness. Left‐handedness is more prevalent in heterosexual men and lesbian women while right‐handedness is more prevalent in gay men and heterosexual women [4,5].…”

E 2 2 1What ' s known on the subject? and What does the study add? Cerebral lateralization/specialization is a neurophysiological feature that has been documented regarding somatic, psychological and sexual functioning and that may be manifested in differences in hand preference, cognitive style, gonadal hormonal effects and possibly even sexual orientation. In this study we investigated a possible cerebral lateralization effect on sexual response for dihydrotestosterone, using fi nasteride as a hormone-blocking compound.The results of this study differ substantially from other studies examining the effects of fi nasteride on sexual response, presumably due to the greater restrictions we placed on defi ning relevant sexual activity, to our alerting patients to both positive and negative sexual effects and to the fact that we assessed the effects separately in right-handed vs left-handed patients. Handedness, as a proxy for cognitive style and possible lateralization of effect/function, appears to be a relevant factor when considering the sexual effects of specifi c gonadal hormones. OBJECTIVE• To investigate the relationships between pharmacologically induced deprivation of dihydrotestosterone, sexual arousal, libido and hand preference, by comparing the self-reported sexual response prior to and during reception of the anti-androgen fi nasteride in men undergoing treatment for male pattern baldness. PATIENTS AND METHOD• In total, 33 sexually healthy Romanian men participated in this study.• Patients prospectively provided information regarding their sexual functioning (over 4 weeks), as measured by the International Index of Erectile Function (IIEF) prior to and after commencing treatment with 1 mg fi nasteride for male pattern baldness. RESULTS• Overall IIEF scores as well as the erectile function, orgasmic function, sexual desire and overall satisfaction subscales showed group, treatment and group by treatment effects.• The intercourse satisfaction subscale showed group and group by treatment effects.• On most subscales, right-handed men showed no effect or lower sexual function whereas left-handed men reported no effect or improved sexual function, primarily. CONCLUSIONS• These results suggest that the sexual effects of dihydrotestosterone deprivation may depend on handedness -a proxy variable that may represent cognitive style -which lends further support to the idea of two distinct neuroendocrine psychosexual axes.• They further suggest that detection of such sexual effects may be enhanced by using research methodologies and communication strategies that increase patients ' sensitization to such effects. KEYWORDS INTRODUCTIONSexual hormones, sexual orientation, cognitive style and handedness may all be interrelated. For example, sexual hormones may be related to an individual ' s sexual orientation [ 1 ] , with androgens possibly operating in gay men and heterosexual women, and oestrogens operating in heterosexual men and lesbian women [ 2,3 ] . Sexual orientation may also, however, be linked to handedn...

“…However, handedness may also serve as an index of prenatal hormone exposure. Perelle and Ehrman (1994) found men to be left handed slightly more often than women (see also Pattatucci, Patterson, Benjamin, & Hamer, 1998). Increased left-handedness is also found in populations where prenatal hormone levels were increased, such as androgens in congenital adrenal hyperplasia (Nass et al, 1987) and women born to mothers who took diethylstilbestrol, a non-steroidal synthetic estrogen (Smith & Hines, 2000).…”

Fluctuating Asymmetry and Sexual Orientation in Men and Women

The present study measured handedness and bodily fluctuating asymmetry (FA), two markers of developmental instability, in 89 heterosexual and 78 gay men and women. Asymmetry in ear breadth, ear length, ankle breadth, second digit length, fourth digit length, and two composite indices were calculated for each participant and a modified Edinburgh Inventory was used to assess handedness. Results showed that, for men, there was a significant positive correlation between three measures of FA and sexual orientation scores (SOS). As ear breadth FA and two composite FA scores increased so did SOS on a modified Kinsey scale (where 0 indicated exclusive heterosexuality and 6 indicated exclusive homosexuality). No significant relationships were found between SOS and FA for women. Similarly, sexual orientation was not related to handedness for either sex. The theoretical implications of the present results are discussed.
