His bestseller "The woman inside of me", published by Random House in 2014, has been sold in many countries all over the world with special editions in Japan and Korea. In this book, he describes his three-year experiment to live as a woman. The book has been filmed by Iranian director Dariush Rafiy for Arte television ("Christian and Christiane", 90 min., 2015). With "Genderkey" (Ariston/Randomhouse, 2016), Seidel has published a significant analysis of the gender roles and their stereotypes, which he describes as "destructively dominating our lives, especially women's lives". "Genderkey" has caused a public debate in Germany, Austria and France. In interviews, the author has criticized the "phlegmatic behaviour of men within the gender debate. With his last work "Ich komme" ("I am coming") the author has initiated a critical debate about male sexuality, again accusing "the loud male silence" in the #metoo debate. Seidel is teaching about gender roles in seminars, as well as consulting the image of personalities.
