One study published in the International Journal of Transgender Health found that in 20% of identical twin pairs, if one twin was trans, the other was as well, compared to only 2.6% of non-identical twins where this was the case; researchers attribute this to their shared genetics.Sexologist Ray Blanchard created a taxonomy of male-to-female transsexualism that proposes two distinct etiologies for androphilic and gynephilic individuals; this taxonomy has become controversial, supported by J. Michael Bailey, Anne Lawrence, James Cantor and others, but opposed by Charles Allen Moser, Julia Serano, and the World Professional Association for Transgender Health. Focus on trans women over trans men
Historically, formal efforts by the medical community to provide transsexual healthcare were extremely focused on transsexual women, with little thought for transsexual men. Julia Serano suggests that effemimania (the idea that male femininity is more psychopathological than female masculinity) was the driving factor. She sees this as a kind of transmisogyny (hatred of trans women as an extension of sexism). : 126–127  This effimimania conflates male homosexuality, MTF transsexuality, and feminine gender expression, while treating them all as a disease. : 129  She points to the medical communitys long love of now outdated theories such as autogynephilia. : 131

Medical assistance
Individuals make different choices regarding sex reassignment therapy, which may include hormones, minor to extensive surgery, social changes, and psychological interventions. The extent of medical intervention is a highly personal decision: there is no one-size-fits-all solution. Hormone replacement therapy
Transsexual individuals frequently opt for masculinizing or feminizing hormone replacement therapy (HRT) to modify secondary sex characteristics.
