There is a new (new to us, anyway) twist in the scrotal asymmetry story: a new form of underwear, offered for sale under the description “String Latéral Flash Bleu Alter”.
The most recent, and most celebrated, part of the saga was the awarding in 2002 of the Ig Nobel Prize for medicine to Chris McManus of University College London, for his excruciatingly balanced report, “Scrotal Asymmetry in Man and in Ancient Sculpture.” [PUBLISHED IN: Nature, vol. 259, February 5, 1976, p. 426.]
(Thanks to investigator David Dobbs for bringing this new device to our and the world’s attention.)
