And here is a short HRW press release regarding the report: https://www.hrw.org/news/2017/07/25/us-harmful-surgery-intersex-children.
Back in the late 80’s and early 90’s, I worked full-time on-site in Guatemala through the Harvard Law School Human Rights Program and co-wrote a book-length HRW report on human rights violations in that country.
