What the mainstream news isn’t telling you.
Research shows that ~60-80% of women who take Plan B in the fertile window still ovulate, yet the drug is still very effective in preventing pregnancy. There is a great article that explains this science in detail, “The State of The Science, Why Catholic Hospitals Should Not Dispense Plan B.” Let me summarize it for those not acquainted with medical literature:
– When taken before ovulation, Plan B’s mechanism of action is very controversial. Opinionated people cite only the research they want to believe, and omit the rest. This is not science.
When taken during the fertile period (before ovulation) Plan B can either work by preventing ovulation or by preventing implantation of a fertilized egg into the uterus. Plan B’s own website states that Plan B One-Step works by, ‘Altering the endometrium, which may inhibit implantation’ – the implantation of a fertilized egg.
The terminology around this issue is confusing at best, perhaps deceptive. The American College of Obstetrics and Gynecology (ACOG) has defined “pregnancy” as beginning at the implantation of a fertilized egg into the uterus, not conception. So, technically speaking, using ACOG’s definition of pregnancy, Plan B does not cause an abortion. For this reason a lot of media outlets are saying that “Plan B is not an abortion pill,” or “Plan B does not cause an abortion.”
There is evidence that oral contraceptives (birth control pills) can work through a similar mechanism, also preventing implantation of a fertilized egg.
Some organizations have also redefined the term “embryo” to refer to a fertilized egg after implantation. Hence, according to this definition, Plan B does not kill an embryo.
The mechanism of action (MOA) of Plan B is becoming an increasingly important issue. The American Academy of Pediatrics policy statement on emergency contraception also states that physicians should counsel patients on the mechanism of action of emergency contraception. Yet many physicians are not discussing the full mechanism of action of Plan B.
Many healthcare professionals promote contraceptives and emergency contraceptives such as Plan B as a good way to reduce or prevent abortions. In reality, though, we are just killing life at an earlier stage.
This forces Christians to really ponder the miracle of life. What is the value of life at this early stage?
Many, if not most, of my colleagues think I am rather crazy for even caring about this issue. Three colleagues have suggested that I should not be permitted to continue my current practice of medicine based on my views. How can we continue to promote a culture of life in this atmosphere?
