Wooden carvings of male genitals found in the hands of female mummies discovered in northwest China’s Xinjiang Uyghur autonomous region were part of an ancient ritual, not sex toys, according to a new study by Chinese scientists. The phallic carvings measured as small as 4 centimeters in length and were discovered in graves at the Xiaohe Tomb complex in Lop Nur, Xinjiang in the grip of 4,000-year old female mummies.
