Some studies examining the relationship between handedness and sexual orientation have reported that a disproportionate minority of homosexual people exhibit left-handedness,<ref>{{cite journal | vauthors = Lalumière ML, Blanchard R, Zucker KJ | title = Sexual orientation and handedness in men and women: a meta-analysis | journal = Psychological Bulletin | volume = 126 | issue = 4 | pages = 575–92 | date = July 2000 | pmid = 10900997 | doi = 10.1037/0033-2909.126.4.575 }}</ref> though findings are mixed.<ref>{{cite journal | vauthors = Mustanski BS, Bailey JM, Kaspar S | s2cid = 29217315 | title = Dermatoglyphics, handedness, sex, and sexual orientation | journal = Archives of Sexual Behavior | volume = 31 | issue = 1 | pages = 113–22 | date = February 2002 | pmid = 11910784 | doi = 10.1023/A:1014039403752 }}</ref><ref>{{cite journal |last1=Williams |first1=Terrance J. |last2=Pepitone |first2=Michelle E. |last3=Christensen |first3=Scott E. |last4=Cooke |first4=Bradley M. |last5=Huberman |first5=Andrew D. |last6=Breedlove |first6=Nicholas J. |last7=Breedlove |first7=Tessa J. |last8=Jordan |first8=Cynthia L. |author9-link=Marc Breedlove |last9=Breedlove |first9=S.

A 2001 study also found that people assigned male at birth whose [[gender identity]] did not align with their assigned sex, were more than twice as likely to be left-handed than a clinical [[control group]] (19.5% vs. 8.3%, respectively).<ref>{{cite journal | vauthors = Zucker KJ, Beaulieu N, Bradley SJ, Grimshaw GM, Wilcox A | s2cid = 4987839 | title = Handedness in boys with gender identity disorder | journal = Journal of Child Psychology and Psychiatry, and Allied Disciplines | volume = 42 | issue = 6 | pages = 767–76 | date = September 2001 | pmid = 11583249 | doi = 10.1111/1469-7610.00773 }}</ref>

[[Paraphilia]]s (atypical sexual interests) have also been linked to higher rates of left-handedness. A 2008 study analyzing the sexual fantasies of 200 males found "elevated paraphilic interests were correlated with elevated non-right handedness".<ref>{{cite journal | vauthors = Rahman Q, Symeonides DJ | s2cid = 22274418 | title = Neurodevelopmental correlates of paraphilic sexual interests in men | journal = Archives of Sexual Behavior | volume = 37 | issue = 1 | pages = 166–72 | date = February 2008 | pmid = 18074220 | doi = 10.1007/s10508-007-9255-3 }}</ref> Greater rates of left-handedness have also been documented among [[pedophilia|pedophiles]].<ref>{{cite journal | vauthors = Blanchard R, Kolla NJ, Cantor JM, Klassen PE, Dickey R, Kuban ME, Blak T | s2cid = 220359453 | title = IQ, handedness, and pedophilia in adult male patients stratified by referral source | journal = Sexual Abuse | volume = 19 | issue = 3 | pages = 285–309 | date = September 2007 | pmid = 17634757 | doi = 10.1177/107906320701900307 }}</ref><ref>{{cite journal | vauthors = Cantor JM, Klassen PE, Dickey R, Christensen BK, Kuban ME, Blak T, Williams NS, Blanchard R | s2cid = 6427342 | display-authors = 6 | title = Handedness in pedophilia and hebephilia | journal = Archives of Sexual Behavior | volume = 34 | issue = 4 | pages = 447–59 | date = August 2005 | pmid = 16010467 | doi = 10.1007/s10508-005-4344-7 }}</ref><ref>{{cite journal | vauthors = Bogaert AF | s2cid = 28513717 | title = Handedness, criminality, and sexual offending | journal = Neuropsychologia | volume = 39 | issue = 5 | pages = 465–9 | year = 2001 | pmid = 11254928 | doi = 10.1016/S0028-3932(00)00134-2 }}</ref><ref>{{cite journal | vauthors = Dyshniku F, Murray ME, Fazio RL, Lykins AD, Cantor JM | s2cid = 25667170 | title = Minor Physical Anomalies as a Window into the Prenatal Origins of Pedophilia | journal = Archives of Sexual Behavior | volume = 44 | issue = 8 | pages = 2151–9 | date = November 2015 | pmid = 26058490 | doi = 10.1007/s10508-015-0564-7 }}</ref>

A 2014 study attempting to analyze the biological markers of [[asexuality]] asserts that non-sexual men and women were 2.4 and 2.5 times, respectively, more likely to be left-handed than their heterosexual counterparts.<ref name=Yule>{{cite journal | vauthors = Yule MA, Brotto LA, Gorzalka BB | s2cid = 5347734 | title = Biological markers of asexuality: Handedness, birth order, and finger length ratios in self-identified asexual men and women | journal = Archives of Sexual Behavior | volume = 43 | issue = 2 | pages = 299–310 | date = February 2014 | pmid = 24045903 | doi = 10.1007/s10508-013-0175-0 }}</ref>
