The play has been adapted into an opera by Francis Poulenc. It also has been translated twice, first by Louis Simpson in the 1960s and then by Maya Slater in 2009. In 2010, Eric "Wally" Wallach adapted and directed The Breasts of Tiresias: A Surrealist Musical in Paris.

Inspired by the story of the Theban soothsayer Teiresias, the author inverted the myth to produce a provocative interpretation with feminist and pacifist elements. He tells the story of Thérèse, who changes her sex to obtain power among men, with the aim of changing customs, subverting the past, and establishing equality between the sexes.
