Male 'Virginity Test' Helps Free 3 in Rape Case Ears never lie, says Vietnamese acupuncturist By Rob Quinn, Newser Staff Posted Jul 2, 2010 5:39 AM CDT 52 comments Comments "From the medical point of view, it's impossible to determine whether a man has had sex or not by feeling the pulse or examining the red spot on their ears," acupuncturist Nguyen Van Hao said. (Wikimedia Commons) (Newser) – Men who have small red spots on the back of their ears are invariably virgins, according to celebrity Vietnamese acupuncturist Pham Thi Hong. Hong fought to free three convicted rapists from prison after she discovered that the men had the spots, the AP reports. Hong's determination to have the case reopened (she threatened to light herself on fire) caused prosecutors to do just that—the men were released after investigators found flaws in the initial case. "They all had small red spots on the back of their ears," Hong says. "The spots should have disappeared if they had had sex. My many years of experience told me that these men did not have sex before." Gay sex or masturbation won't make the spots disappear, she says. Her alleged virgin-detecting abilities have been met with skepticism from fellow acupuncturists.
