St. Louis • "The question of rape always stirs the emotions whenever it is introduced into the abortion debate," Fred Mecklenburg wrote in 1972. "Unfortunately, the emotional impact of rape often clouds the real issues and the real facts."
Mecklenburg — an assistant clinical professor of obstetrics and gynecology at the University of Minnesota Medical School at the time — could not have known how prescient his words would feel 40 years later.
While Rep. Todd Akin, R-Mo., cited only "doctors" as his source of information about the rarity of pregnancy resulting from rape, it is two pages, from Mecklenburg’s 1972 article, "The Indications for Induced Abortion: A Physician’s Perspective," that have influenced two generations of anti-abortion activists hoping to build a medical case to ban all abortions without exception.
In Mecklenburg’s original piece, he wrote that pregnancy resulting from rape "is extremely rare" and cited as an example Buffalo, N.Y., which had not seen "a pregnancy from confirmed rape in over 30 years." Other cities — Chicago, Washington, D.C., St. Paul, Minn. — also had experienced lengthy spells without a rape-caused pregnancy, Mecklenburg wrote.
The reasons were numerous: Not all rapes result in "a completed act of intercourse," Mecklenburg wrote. He added that it was "improbable" that a rape would occur "on the one to two days of the month in which the woman would be fertile."
Mecklenburg’s third reason seems to have been picked up by Akin, who made his comments in a TV interview Sunday.
A woman exposed to the trauma of rape, Mecklenburg wrote, "will not ovulate even if she is ‘scheduled’ to."
But a host of other research disputes Mecklenburg’s conclusions, both on the scarcity of pregnancy after rape and natural defenses to prevent conception.
"From a scientific standpoint, what’s legitimate and fair to say is that a woman who is raped has the same chances of getting pregnant as a woman who engaged in consensual intercourse during the same time in her menstrual cycle," said Barbara Levy, vice president for health policy at the American Congress of Obstetricians and Gynecologists.
One widely accepted study suggests a 5 percent post-rape pregnancy rate, resulting in 32,000 pregnancies a year.
The report was from the Medical University of South Carolina and was published in the American Journal of Obstetrics and Gynecology and cited by the U.S. Centers for Disease Control and Prevention.
But placing an exact figure on post-rape pregnancy is problematic, primarily because sexual assaults are thought to be underreported. Another factor is the availability of over-the-counter emergency contraception, which can prevent fertilization when taken after intercourse.
One study from the journal Human Nature in 2003 suggests pregnancy rates are higher after a rape when compared with consensual sex because of the inconsistency of birth-control use.
Mecklenburg’s article was one of 19 in a book called, Abortion and Social Justice, published a year before the U.S. Supreme Court’s Roe v. Wade decision.
In supporting his claim about trauma and ovulation, Mecklenburg cited experiments conducted in Nazi death camps.
The Nazis tested this hypothesis "by selecting women who were about to ovulate and sending them to the gas chambers, only to bring them back after their realistic mock-killing, to see what the effect this had on their ovulatory patterns. An extremely high percentage of these women did not ovulate."
Finally, Mecklenburg said it was likely that the rapists — because of "frequent masturbation" — were unlikely to be fertile themselves.
The book was edited by a doctor and a lawyer, and funded by Americans United for Life, the major legal arm of the anti-abortion movement.
Americans United for Life was founded by Brent Bozell, a Catholic activist who wrote for the National Review.Next Page >
