A total of 393 virgin births have been reported in the United States in the last 14 years according to research conducted by scientists at the University of North Carolina at Chapel Hill that was reported in the Dec. 17, 2013, issue of the British Medical Journal.
The researchers used data from the U. S. National Longitudinal Study of Adolescent Health that reported the virginity status, rate of vaginal sexual intercourse, use of assisted pregnancy methods, and the pregnancy history of 7,870 women who were adolescents or young adults.
The researchers also recorded the participation of each individual in taking a chastity pledge, the importance of religion to each individual, and their knowledge of any and all methods of birth control.
The researchers report that "around 0.5% of women affirmed their status as virgins and did not use assisted reproductive technology, yet reported virgin births."
Sixty percent of the virgin births were male and 40 percent were female.
Factors that the researchers consider to be relevant and important to the reporting of virgin births were cultural and religious beliefs that valued virginity, participation in the signing of chastity pledges, and a lack of parental discussion of sex or birth control with the women who reported a virgin birth.
Mechanical and statistical measures were used to detect the potential of prevarication on the part of all women involved in the 14-year study and yet those women who reported a virgin birth truly believed they had experienced a virgin birth.
