In the nineteenth and early twentieth century, hysteria was a common psychiatric diagnosis made primarily in women. The existence and nature of a purported male hysteria (hysteria masculina[1]) was a debated topic around the turn of the century. It was originally believed that men could not suffer from hysteria because of their lack of uterus.[2] This belief was discarded in the 17th century when discourse identified the brain or mind, and not reproductive organs, as the root cause of hysteria.[3] During World War I, hysterical men were diagnosed with shell shock or war neurosis, which later went on to shape modern theories on PTSD. The notion of male hysteria was initially connected to the post-traumatic disorder known as railway spine; later, it became associated with war neurosis.
