The "Act on Sterilisation and Castration" (), adopted in June 1929, was one of the first gender change laws in the world. The first person to successfully undertake a legal gender change in Denmark, which required undergoing sex reassignment surgery, was American Christine Jorgensen in the early 1950s. She underwent an orchiectomy and a penectomy in Copenhagen in 1951 and 1952, respectively. Danish transgender woman Lili Elbe, who inspired the 2015 movie "The Danish Girl", was one of the first identifiable recipients of sex reassignment surgery. She transitioned in Germany in 1930, and later had her sex and name legally changed on her Danish passport.
