"The incidence of genital surgery increased over time: in 2000–2005, 72.0 percent of patients who underwent gender-affirming procedures had genital surgery," the study's abstract states. "In 2006–2011, 83.9 percent of patients who underwent gender-affirming procedures had genital surgery."
"Most patients (2,319 of 4,118 [56.3 percent]) undergoing these procedures were not covered by any health insurance plan," the study continues. "The number of patients seeking these procedures who were covered by Medicare or Medicaid increased by threefold in 2014 (to 70) compared with 2012–2013 (from 25)."
Researchers also concluded that the number of transgender people seeking such surgery has been underestimated by past studies:
"...Although some studies have estimated that only 20 percent to 40 percent of transgender individuals seek [gender reassignment] surgery, these estimates are only based on surveys of convenience samples of transgender individuals, which limits their generalizability."
"As transgender individuals have become more visible in mainstream society, we hypothesize that an increasing number of [gender reassignment] surgical procedures have occurred over time," the study adds.
Supporting the study's hypothesis on a global scale is data from last year uncovered by The Telegraph which found that the number of British children referred to "gender identity clinics" had increased over the past five years.
The statistics obtained by the Telegraph from the Gender Identity Development Service indicated that 84 children aged between 3 and 7 were referred to the clinic in 2016, while only 20 received such a referral from 2012–2013.
"It has become an industry, people are making a career out of encouraging children to question gender at an age when they need to be left to be children," Chris McGovern, a former adviser to the Department for Education, told The Telegraph. "When teachers raise these issues children can become confused or unhappy and traumatized by it."
