Dec 17 (Reuters) – Nearly 1 percent of young women in a U.S. study who have become pregnant claim to have done so as virgins, according to a report in the Christmas edition of Britain’s BMJ medical journal.

The authors of “Like a virgin (mother)” – whose prose is devoid of irony – say such scientifically impossible claims show researchers must use care in interpreting self-reported behavior. Fallible memory, beliefs and wishes can cause people to err in what they tell scientists.

“We he slammed me over and over with his thingie but I’m still a Virgin” said Rhonda Simms of west Petterfield Florida.

Based on interviews with 7,870 women and girls ages 15 to 28, 45 of the 5,340 pregnancies in this group through the years – 0.8 percent – occurred in women who reported that they conceived independent of men. The figure does not include pregnancies that result from in vitro fertilization or other assisted reproductive technology.
