It looks like it’s based on a 2016/2017 CDC survey of rape victims.
The number is that 14.9% of (women) respondents became pregnant from rape.
I would think that could include domestic rape (the right term?) where a woman is repeatedly raped by her domestic partner. Then there would potentially be multiple incidents of rape/intercourse leading to the pregnancy.
Actually, I was able to click thru the letter and identify the sources they used. They didn’t post all the values the used in their formula, which would have been both easy and nice. It would take a deeper reading than I was able to do to understand if the values they are using are fit for purpose. I did notice that some sources they cited used a ~3x1 total vs reported ratio, while they seemed to pick a ~5x1 value (which IIRC came from one of the sources)
On the flip side we did see this. Article on TX birth rates. You could probably then look at rape vs non-rape pregnancy estimates in the sources to cross-check reasonableness. I’d also be thinking about when TX ban was enforced vs when it passed and the time between typical abortion and birth (if abortion wasn’t used) to make sure lag isn’t a big factor.
It seems high to me too, but I suppose that rapes resulting in pregnancy are probably more likely to be reported than rapes that don’t result in pregnancy.
Also younger women are more likely to be raped (I assume) due to a variety of factors, and may also be more likely to rely on barrier methods like condoms since condoms also protect against STDs. Or be virgins who don’t need / use birth control.
It still seems high… just some factors that make it non-analogous to trying to get pregnant.
Whether it’s high or not seems irrelevant to me. What matters is there a not insignificant number of cases even if the rate is half what the article claims.
Eh, you CAN get pregnant at any point in your cycle, including during your period. Sperm can hang out for a while, there can be an errant egg… stuff happens.
You’re at your most fertile the 5 days before ovulation, the day of ovulation, and the following day… so 7 days per cycle or roughly a quarter of the time. But the chances are not 0% the other 21 days… they’re materially lower, but not 0.
(Some women’s cycles are longer or shorter than 28 days, but I think the 25% probably still holds.)
When I started having sex in college my boyfriend used condoms. When my first husband & I were married I used a diaphragm. If you’d asked me “are you using birth control?” I would have answered “yes”, but if I’d been raped that birth control would have done diddly squat to decrease the likelihood of my getting pregnant.
