RT Journal Article SR Electronic T1 The rhythm method and embryonic death JF Journal of Medical Ethics JO J Med Ethics FD BMJ Publishing Group Ltd and Institute of Medical Ethics SP 355 OP 356 DO 10.1136/jme.2005.013920 VO 32 IS 6 A1 L Bovens YR 2006 UL http://jme.bmj.com/content/32/6/355.abstract AB 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.
