Of course. Why not include that as a feature?
Who would want to experience more fear in safe situations?

They really run a number on your emotions. Not surprised to see this but fairly surprised to see it coming out this long after they've been on the market.
What other effects do they have on your emotions? From your perspective?
Anecdotally, I’ve heard from women friends about pills having effect on depression, libido and anxiety. Not super surprising given how much it messes up with hormones
> Their findings showed that ventromedial prefrontal cortex (vmPFC) thickness of women who were using OCs was reduced compared to men

I would expect the study to compare it to other women not using OCs. Does this methodology make some sense that I'm missing?

Bad summary. They compared it to women who stopped taking it and women who never took it as well. That's why they think the effect is reversible.
They did in fact.

> Methods: We recruited healthy adults aged 23-35 who identified as women currently using (n = 62) or having used (n = 37) solely combined OCs, women who never used any hormonal contraceptives (n = 40), or men (n = 41).

> Results: Compared to men, all three groups of women exhibited a larger GMV of the dorsal anterior cingulate cortex, while only current users showed a thinner ventromedial prefrontal cortex. Irrespective of the menstrual cycle phase, never users exhibited a thicker right anterior insular cortex than past users.

I agree with you it’s somewhat confusing why they use men as their benchmark. But really this isn’t my field of expertise.

> who identified as women

What a weird thing to say if you study the effect of the pill on women.

It's not that they "identified as women", it's that they self-identified whether they were using contraceptives or not, i.e. it was not checked.
They could be making it clear that this does not include trans men, who are still capable of getting pregnant despite being on testosterone.
They're still women though really.
no. they're trans men. do some research.
trans men = biological women on biological men's hormones?
Those individuals taking birth control who do not identify as women are likely to be on additional hormones.

Because the full sentence is:

> who identified as women currently using

It's who identified themselves as using or not using contraceptives, not just identifying as women.

Lol. Got the feeling this was some new-speak way of saying they tested women without using the word women, because womanhood is not longer a biological fact but now an opinion.

Thank god it's not.

tl;dr article describing a study [0] by Peyrot,C, Brouillard,A, et al comparing the ventromedial prefrontal cortex volume between the brains of { women using, women abstaining from, women who never used, men } oral contraceptives. They found reduced volume in the brains of women using contraceptives and some amount of recovery in women abstaining. The linked article is ambiguous about whether the effect dampens or increases fear, but the study indicates a correlation between hormonal contraceptives and higher stress.

Does the study control for whether the women have a cat or not?

due to toxoplasmosis?
I would assume the parent meant toxo but it's a weird segue. To my knowledge, toxo doesn't distinctly impact what's under study here.
Being infected with toxoplasmosis could be an interesting thing to control for, for all subjects, but their samples are already relatively small, so I am not sure any observation would be significant…
(comment deleted)
Potential for correlation here. Just anecdata, but childless people very often have pets instead, at least taking the sample of people I know. So perhaps pet (and so cat) ownership and long term birth control are correlated to some degree.
Parents with newborns aren't looking for something else to care for. When the kids get older, the pets reappear right where they were.
There has been research done that suggested that infection with toxoplasmosis affects perception of risk.
Being raised with neglect or abuse is one of the many, many factors that can influence risk perception. Toxo seems like small fish in that big pond.

Why do people use pills rather than copper IUDs? At least based on information on the web, it seems copper IUDs are strictly better: cheap, easy to insert and remove, nothing to do after initial insertion, no side effects other than "increased menstrual flow".
> no side effects other than "increased menstrual flow".

It's my understanding that with birth control pills, a woman can indefinitely delay her menstrual cycle. I can absolutely see some making a choice to not have periods at all, if the other side effects for them are negligible. An option that not only brings periods back but makes them messier would not look very attractive in comparison.

As with most things health and lifestyle, everything involves tradeoffs, and choices are dependent on individual valuation of those tradeoffs.

Does that mean her eggs aren't being used up?
Most doctors won't give patients pain meds beyond NSAIDs, even though the insertion procedure is very painful.

> easy to insert and remove

Aren't they meant to be extremely painful to insert/remove?

Why do people prefer not to have longer and potentially more painful periods?

Have you ever experienced recurring or ongoing debilitating pain? Going from 1-2 days of pain per month to more doesn't sound like "no side effects".

If you have a toddler, they like to jump on your body and belly at random times, leading to increased risk of perforation. Same likely applies if you have a more active lifestyle.
Birth control pills can help with other conditions in addition to / aside from contraception. My understanding is that they are used, for example, to try to treat symptoms of endometriosis and have been used to control acne. Dr. Google claims they can even help lower the risks of some cancers.

IUDs can cause side-effects especially the first few cycles after insertion.

Not true, I have had exes with IUIs and they all had crippling pain and much worse cramping with them. In every case I talked them into get rid of the IUI, and the pain went away.

The best birth control method (as defined by least side effects and max efficacy) I’ve come across is cycle tracking / family planning (called that because you can use it to get pregnant as well as prevent pregnancy). It’s simple (you can only get pregnant at certain times in your cycle), but there’s nothing for pharma to sell (it’s free!). Weirdly, doctors never seem to trust women to go through with it (and always try to push medicated birth control), but it’s easy, even before Apple added it to their products.

You may want to rethink "max efficacy" there for the natural family planning approach.

There are multiple methods (temp tracking, calendar tracking, vaginal mucus tracking, etc) that fall under the general header of natural family planning. High efficacy numbers only come with extremely consistent use of multiple methods. With all that work, it ties with the effectiveness of birth control pills. With only a portion of that work, it's not very effective at all in comparison.

From https://www.plannedparenthood.org/learn/birth-control/fertil... -

> FAMs are about 77%–98% effective. That means 2–23 out of 100 couples who use FAMs will get pregnant each year, depending on which method(s) are used. If you use multiple FAMs together, they work even better.

> The better you are about using FAMs the right way — tracking your fertility signs daily and avoiding sex or using birth control on “unsafe” days — the more effective they’ll be. But there’s a chance that you’ll still get pregnant, even if you always use them perfectly.

Cycle tracking is pretty unreliable. It's also dangerous to record that information when it may be used against you if you do get pregnant and have an abortion.

What are the socio-political effects of mass psychological changes brought about by putting a large chunk of the population on medications without full knowledge of the side effects?

Imagine putting an equally large percentage of the population on androgenic medications.

> What are the socio-political effects of mass psychological changes brought about by putting a large chunk of the population on medications without full knowledge of the side effects?

Not really a question big pharma is interested in discussing ...

Because there's no reason to assume that the "default" state of nature is some ideal or good for anything. It could be but what are the odds? We're still apes in a world that changed wildly out of pace with the speed of natural evolution.

> equally large percentage of the population on androgenic medications

Its funny you say this because doing this would actually put humanity back to the testosterone levels men had for most of human history.

> s funny you say this because doing this would actually put humanity back to the testosterone levels men had for most of human history.

Women and men respond differently to testosterone, so this argument does not hold.

The equally large population you wanted to give testosterone to wasn't men?
> Because there's no reason to assume that the "default" state of nature is some ideal or good for anything.

But there is? Thousands of years of evolution is actually a pretty high bar to pass.

If you're gonna make this case you're going to have to additionally argue that said evolution makes sense in an environment that is not the one we evolved to survive in. A lot of our evolutionary baggage is maladaptive.
How do you feel about modern medical therapies? The default state of nature does not include them.
It’s never perfect, but it still is a high barrier to pass.

As for modern therapies, I mean - depends? A lot of our modern illnesses also simply didn’t exist at the scale they do now.

Heart disease has been going up steadily in the past few centuries for example.

ADHD is an interesting one too. I have ADHD. For the vast majority of human history it probably won’t have been a big deal for my mental health, but it is now due to what’s expected of me.

What are the socio-political effects of massively increasing lifespan without full knowledge of the side effects?

Imagine what would happen if people start routinely living to 150.

Probably people would become more risk-averse, on average. Interest rates would tend to go lower, as money in the future would gain relative value compared to present money.
Curious if it's this black and white. Normally, younger people are advised to have portfolios that tend riskier, as they have more time to make up for downturns in the markets, which (it is at least taken for granted) otherwise are on a perpetual upward trend. Even if we assume retirement still happens at 65, and you're just extending the length of retirement, that'd be a reason why you need your portfolio to do MORE heavy lifting for you to get the amount you'll need to cover that long retirement, so it'd suggest a higher appetite for risk. If you're working longer, on the other hand, all the more ability to weather downturns in the market, and so less out of necessity and more opportunity, the appetite for risk would also seem to increase, for most persons.

I assume you were talking more about physical risk taking though, because as "tomorrow you may die" becomes less and less likely, you're perhaps that much less incentivized to "live for today" (to deconstruct the popular boomer adage). This angle I'd take less issue with.

A good friend of mine developed a serious case of pcos from birth control medication which started in her teen years. It's impacting her fertility, growing facial hair, pre-diabetes symptoms, and impacting weight gain/loss. Her doctors just "shrug" and suggest to get back on birth control as a solution. Imagine allowing your teenage daughter to be on a semi-permeant dosage of hormone altering poison.
I didn’t think PCOS could be triggered by birth control - doesn’t seem to be a lot of evidence to support this either. Looking at the mechanism of action of COCs, I can’t think of a mechanism of why COCs would cause PCOS. Oral contraceptives are usually first line in treating PCOS which makes this anecdote even more weird. Can you provide any more information?
Its not an officially supported theory, but there's alot of anecdotal evidence out there that going off of BC after many years can cause these symptoms with some women.
If using OC is a possible treatment, wouldn't the likelier explanation be that using it suppressed the preexisting condition and quitting just revealed the symptoms?
Contraceptive pill simulates pregnancy at hormonal levels. That includes partner selection and preferences. Imagine your partner is on a pill while you date, you get married and try for kids. She stops pill and there is a huge change in her chemistry .

It also stops ovulation. It plays a huge role in female sexuality, to the point some people have trouble to orgasm.

> Imagine your partner is on a pill while you date, you get married and try for kids. She stops pill and there is a huge change in her chemistry.

Why imagine this?

We want to believe attraction and desire is more free will then it is (vs hormones and brain chemistry), and there is uncertainty of whether a relationship will persist when birth control use changes.

https://behavioralscientist.org/quality-sex-relationships-bi...

> But an even bigger positive is what comes when we look at the divorce rate. Despite the whole my-sex-life-is-meh-and-I-am-not-that-attracted-to-my-partner thing, women who chose their partners when they were on the pill were significantly less likely to divorce than women who chose their partners when they were off it (!!!).

> This suggests that being on the pill may lead women to choose partners who are good resource providers and willing to stick with them through thick and thin (hence the lower divorce rate and greater satisfaction with resource investment). However, equally as noteworthy, this research found that when these pill-taking women did get divorced, they were overwhelmingly the ones who initiated it (they were the initiators 84.5 percent of the time, compared to being the initiators 73.6 percent of the time among those who chose their partners when not on the pill). This suggests that, in choosing these faithful, resource-investing men as partners (and at the expense of sexiness), pill-taking women may be putting themselves at risk for becoming dissatisfied with their relationship due to a lack of attraction and sexual satisfaction if they ever go off of it.

Emphasis is author's.

> It plays a huge role in female sexuality, to the point some people have trouble to orgasm.

You're just pumping in outliers here. What are you trying to achieve with this?

Stats give that to around 15%, it is not an outlier.

Side effect from hormonal pills is not some sort of conspiracy. Go to feminist forum and ask about it.

> Stats give that to around 15%, it is not an outlier.

What stats? Fifteen percent of what - time? women? sexual events? Is this even about climax?

Of all the things that can inhibit climax for women, why should contraception be singled out for elevated concern?

Can we say that women who ovulate, are more horny and more likely to orgasm?
12 year olds ovulate and have cycles. Post-menopausal folks don't ovulate, yet can still be horny and still orgasm. So do folks that have had surgery to remove their ovaries. And so do folks that ovulate irregularly. Many women who ovulate regularly aren't all that horny (I've met them, and I'm happily not one of them) and some women go large chunks of their life, having children and jobs and everything, but rarely orgasm. Other women aren't realistically pain-free or worry-free enough without birth control to manage to be horny and/or orgasm. Needless to say: Ovulating doesn't mean more horny and more likely to orgasm.

Hormones/ovulation are only part of the story.

We can say anything,

Whether it is a justified belief on average is another question.

> Contraceptive pill simulates pregnancy at hormonal levels. That includes partner selection and preferences. Imagine your partner is on a pill while you date, you get married and try for kids. She stops pill and there is a huge change in her chemistry .

I have no problem imagining this, since it is, in fact, exactly what happened for me and my wife. (Not the only "huge change" in her or my chemistry, either -- weight changes and pregnancy and giving birth and COVID and... well, lots of things change body chemistry a lot.)

Not sure why you are saying this like it is something particularly alarming, though.

The "alarming", if charmingly idiotic bro-science read of that, is that as soon as the wife is off the hormonal contraceptive pill, they will stop wanting to have sex, and additionally, realize they don't actually like their partner, and that it was the just drugs talking.

If you’re a man who doesn’t want children or has finished having children: get a vasectomy. They’re easy, low risk and help reduce the (significant) contraceptive burden on partners.

(Although technically a vasectomy is reversible, it isn’t guaranteed and so a vasectomy is not a good option if you intend to have children someday)

I consider it a hardware upgrade.
Software upgrade: immutable by default. :)
Not as easy as the current trend of "just get a vasectomy, it's easy and reversible" suggests. The problem with a vasectomy is that there is a low, but non-zero chance that you get long-lasting pain from it. After all, they cut through a bunch of nerves and muscles. These aren't just some dumb useless tubes.

So, given you're in a stable relationship, you essential trade X years of care-free sex (until menopause) for a slight risk that it fucks you up pretty badly. In other words: the potential upside is limited, the potential downside is quite severe.

Regarding reversibility: Not as easy. It's a sophisticated operation which requires a specialist and takes 2-3 hours. If your body produces more sperm than it can absorb, they might rupture tiny tubes in your epididymis, which makes it almost impossible to reverse. The risk is higher the longer ago the vasectomy was.

Friend had a lot of pain from one going bad. He's stil happy with it now. But not entirely risk free.
> suggesting a mechanism on how OC use could impair emotion regulation in women

This doesn't surprise me the slightest, as I've noticed change in behavior in my ex-girlfriend between the periods (pun intended) she was on pill or not. She was more emotional, and seemed to have a bit harder time to control herself.

It's quite scary how medicine with such impact are marketed as something quite benign, even by public institutions.

I appreciate that people are looking into this, and I think more research of this kind should be funded. However, one needs to be cautious when claiming an "impairment" in fear regulating regions from a measure of cortical thickness with MRI. For once, there is no evidence that a slightly thinner or larger cortical thickness means better or worse regulation of any kind. Second, morphology studies are susceptible to many sources of biases which are not really addressed in this study. For example, anything that affects hydration levels or causes a redistribution of blood and cerebral spinal fluid volume can lead to significant changes in measures of cortical thickness, since they will change the contrast between gray and white matter that drive cortical thickness measurements.

Changes in thickness have been found even when comparing people scanned in the morning and in the evening [1]. Any drug intervention could be expected to cause physiological changes that could act as confounds. Also, in the discussion one reads: "Interestingly, no lasting effects of combined oral contraceptives (COCs) use were detected when comparing the four groups." This suggests that the changes could be driven by physiological changes instead of permanent changes in brain circuitry.

It would be great to see a follow up study controlling for potential confounding effects (for example, measuring baseline perfusion, blood pressure and controlling for time of day effects and usage of other drugs), and expanding the study with functional tests that involve fear regulation.
