St. Blog’s Parish will soon be all aflutter with news that Luc Bovens, a professor of philosophy at the London School of Economics, has written an article ("The rhythm method and embryonic death", J Med Ethics 32: 355-356) that links the use of the "rhythm method" with embryonic death, i.e. early miscarriage or spontaneous abortion.

"Some proponents of the pro-life movement argue against morning after pills, IUDs, and contraceptive pills on grounds of a concern for causing embryonic death. What has gone unnoticed, however, is that the pro-life line of argumentation can be extended to the rhythm method of contraception as well. Given certain plausible empirical assumptions, the rhythm method may well be responsible for a much higher number of embryonic deaths than some other contraceptive techniques."

Though some responses to the sloppy arguments made in this paper have been made by American Papist, Epiphany, and other bloggers, I do not believe the responses I’ve so far seen address the scientific/statistical aspects of Bovens’ claims. For instance, they rightly point out that the rhythm method was long ago replaced by much more reliable empirical methods collectively known as natural family planning (NFP). However, I suspect that Bovens chose to deliberately seem ignorant of pro-life/anti-contraceptive terminology in order to subtly mock what he sees as ignorance of reproductive medicine on the part of those who call the birth control pill abortifacient. I fear that Catholic bloggers have allowed themselves to be distracted by a red herring.
