One in 200 American mothers 'became pregnant without having sex'

The results of a long-term study of reproductive health, published in the British Medical Journal, have revealed that one in two hundred US women claim to have given birth without ever having had sexual intercourse.

The findings were based on a study of 7,870 women and girls aged 15 to 28, as part of the National Longitudinal Study of Adolescent Health, which ran from 1995 to 2009.
