Truth In Advertising: An Unborn Baby’s Beating Heart

misleading baby's heartbeat billboard

Above is one version of a common billboard along the interstates in Florida and across America. The problem for me is that the spokesman didn’t look anything like that when he was 18 days from conception; he would have been barely visible and a lot less cuddly. Below, I’ve taken the liberty to replace him with his earlier self, which would have been about half the size of a pea or just able to fit through the pupil in the eye of his older self as shown in the background of the revised billboard. His heart would have been larger than a grain of sand. He still has no eyes, arms, or lungs, and I’ve found no information on brain function. I don’t think he’s feeling any pain. Now ain’t that cute?

His Odds Of Success

While I have touched on this subject before (in my article Save Your Birthday – Vote For Clinton), this time I dug deeper in order to put things into a more serious perspective. Here’s what I found:

  • According to ABORT73.COM, abortions have been decreasing slightly every year for the last decade. 879 thousand occurring in the United States in 2017.
  • The Statistica website says that the number of births in this country has been fairly stable. There were about 3.86 million of them in 2017.
  • The attrition rate of fertilized human eggs is not as well known. Comparing articles on spontaneous abortion in humans and Early embryo mortality in natural human reproduction, it looks like only 25% of fertilized eggs actually make it to birth (± at least 10%).

Here’s what that means: if you start with 18 fertilized human eggs, 13 will die from natural causes before birth, and one embryo or fetus would be aborted. Both forms of attrition are “front-loaded”; 2/3 of abortions happen by the 8th weekA1, while 2/3 of fertilized eggs will die in their first 11 weeksA2.

A common mistake would be to compare the number of abortions with the number of births directly but to compare apples to apples, as they say, you need to use the same reference point. Here’s the math:

3.86 million births divided by 25% (or 0.25) gives 15.4 million fertilized eggs. That would be the common reference point. Divide that by 879 thousand abortions and you get the total number of fertilized eggs there are for every abortion (17.6 – let’s round to 18). To find the number of those fertilized eggs that would die naturally, simply multiply the same 18 by 75% (or 0.75).


One thing that is not clear is “what are the odds that the aborted “child” would have died from natural causes anyway?” The easy answer (and my best guess so far) is 75%. That means there are a lot of self-righteous people out there (many being middle-aged white males with nothing invested) who are willing to throw a woman in jail for long periods of time without even caring about the circumstances of her case to protect something that probably wasn’t going to make it anyway. I guess for the pious, any excuse is a good one for beating up on your neighbor.

At least that’s the way I see it. Any comments?
