The Cutting Edge-July 2013

“The International Journal of Transgenderism,” Jan.-Mar.
2013 features an article, “Transsexuality
Among Twins: Identity Concordance, Transition, Rearing, and Orientation”
by a renown researcher in the field, Dr. Milton Diamond. It examines the interface between genetic and
environmental factors in the development of gender identity through the study
of identical and fraternal twins. As you
can imagine it was difficult to locate subjects for this study. Finally 112 sets of twins within which one or
both had transitioned from one gender to the other were included. Some of the findings are as follows: It is more likely that identical twins and
male twins (as opposed to non-twinned siblings) would both transition
suggesting a role for genetic factors in the development of gender
dysphoria. However, the majority (56%)
of identical twins did not transition, concurrently reinforcing prior knowledge
that “even identical twins … are not completely identical in gene
configurations.” For a fuller discussion
of this subject, see N. L. Segal’s book, “Born together-Reared Apart,”
published in 2012. At the end of the article the author pleads for twin sets to
enlarge the study with the aim of improving the lives of transgendered
people. If interested, please contact

sports teams based on their gender identity, marking some of the strongest protections for transgender youth
in the country. The Associated Press reports that California already had legal protections in place for
transgender students, but the new bill made those rules more explicit. AB1266 allows K-12 children "to participate in sex-segregated programs, activities and facilities” based on their self-perception rather than their birth gender. A San Francisco Democrat who sponsored the bill said the clearer rules ensure some of the state’s most bullied children will get a “fair shake.”
The AP notes the education department of Massachusetts
and many school districts around the country are adopting similar rules.
A long debate preceded the 21-9 vote in the California
State Senate, including one objection from a senator who suggested that the
rules would allow mediocre male athletes to join female sports teams for
competitive advantage.
