In October 1954, Mohammad Reza told Soraya he was concerned about the fact that she had not given him an heir and suggested that they visit the United States to seek the help of American fertility doctors. In 1954-55, the Imperial couple paid a lengthy visit to the United States, leaving on 5 December 1954. In New York, Soraya visited doctors who assured her that an inability to bear a child was due to the "shocks, upsets and vexations of the last two years", which reassured her, but in Boston, the doctors told her she was infertile and could never have children. Much of the length of their trip was due to the Shah's efforts to do something to console Soraya who took the news that she was infertile very badly. Unaware of what the doctors had revealed to Soraya, "Newsweek" sarcastically wrote "even the "Shahanshah" (King of Kings), Vice Regent of God, Shadow of the Almighty and Center of the Universe deserves a vacation...They imperial couple have spent this winter in a private visit to the U.S...physical check-ups in New York hospitals, sight-seeing in San Francisco, dancing the mambo in Hollywood, skiing in Sun Valley, water-skiing in Miami Beach".
