> the clitoris did not even make it into standard anatomy textbooks until the 38th edition of Gray’s Anatomy was published in 1995.

This seemed surprising, as it hews too close to an annoying meme in feminism and history generally, that people in prior eras were idiots. And it turns out to be wrong. The clitoris was in Gray's Anatomy until 1947, when it was removed by the editor Charles Goss for the 25th edition. See https://projects.huffingtonpost.com/projects/cliteracy/embed... Indeed, the clitoris had been depicted in Classical medical books.

Why it was removed--and stayed removed for nearly 50 years--would make for an interesting story about mid-century culture, if not for a cynical throwaway comment, though it seems nobody knows Goss' actual motivations.

There's a fair amount of modern/modernist-era thinking about bending the chaos of humanity to meet rigid ideal social structures, from about the late nineteenth to late twentieth century. And to be clear, the chaos of the early industrial period led to marked declines in public health, sanitation and the like. Some of these innovations worked reasonably well (the standardization of healthcare and schooling), some of them had unforeseen side effects (replacing horses and their large amounts of fecal matter with cars and invisible pollution), and some straight up did not work (much of the social engineering that went into low-income public housing in the West)

I don’t know about “idiots” but bias towards women was obviously real and prevalent. Treating the idea that that might have influenced medical literature as a “meme” is slightly bizarre to me.

by b800h 2 hours ago

Bias towards women would be understood by most readers as favouring them. I would have written bias against women here.

by wahern 3 hours ago

The meme is that before [insert your contemporary period] people were so backwards that they would miss something like the clitoris entirely. The meme isn't that people and cultures were prejudiced or biased, but that they were prejudiced in an idiotic way. If you believe that's how prejudice works, then you'll be utterly blind to much contemporary prejudice.

EDIT: Relatedly, The Guardian article sites the statistics about female genital mutilation. And you might think, how could people in this day be so cruel? Well, in some (but not all) of those cultures, such as parts of West Africa, female sexual pleasure is highly valued, a clitoral circumcision involves removing the clitoral hood only, similar to circumcision for men, and is viewed as enhancing female sexual pleasure, specifically for oral sex, an act that lacks any negative connotations. Now, embedded in that narrative might be a deeper, more subtle bias against women, but by not appreciating and grappling with that dynamic you're ignoring and diminishing how many women in those cultures understand feminism, which is its own anti-feminine and culturally centric (i.e. "colonial") bias.

by flotzam 2 hours ago

Isn't type 1a circumcision (removal of the clitoral hood, but not other parts) very rare? At least that's what the Wikipedia article claims, referencing a 2008 WHO report.

What’s your best source that African FGM is about enhancing female sexual pleasure, specifically for oral sex?

by wahern 39 minutes ago

This was several years ago and unfortunately I didn't archive my research. Every year it becomes so difficult to dig up stuff, and I don't have time today to go back down that rabbit hole. (These days I'm much better at archiving stuff.)

Here's a couple of articles by one of most vocal supporters of FGM in West Africa:

* https://www.thepatrioticvanguard.com/hurray-for-bondo-women-...

* http://www.fuambaisiaahmadu.com/blogs/my-response-to-fuambai...

And some skeptical but engaging discussions about her views:

* https://journals.library.columbia.edu/index.php/TMR/article/...

* https://www.journals.uchicago.edu/doi/10.14318/hau6.3.011

The second link of the four is a response to the last.

I was sloppy in being too specific in saying removing the clitoral hood was sometimes justified as enhancing oral sex. Now that I think about it, that might be one of the views regarding labial extension, which is often lumped in with FGM but obviously quite different from cutting the clitoral hood. The claims about enhancing sexual pleasure I think largely came from more polemical literature, as well as some English-language African feminist blogs and bulletin boards, and I would suspect those views may be, at least to some extent and in their specificity, recent revisionist justifications. In African discourse there's a reactionary vein that pushes against Western criticisms of traditional African practices, and one of the ways to do that would be to subvert the paternalistic disgust about FGM by explicitly arguing the practice promotes one of the West's other ideals, sex positivity.

To be clear, I'm not trying to defend any of this. Just trying to point out that the West's exceedingly simplistic and categorical perspective hides a very strong cultural prejudice, as well other problematic assumptions about how and why these practices persist.

by IAmBroom 33 minutes ago

So, you admit you have no evidence supporting your bizarre claims, and aren't defending a practice you claimed was at least sometimes without negative connotations. Gotcha.

by wahern 29 minutes ago

My comment about negative connotations was referring to oral sex, where it was claimed the local culture never viewed performing oral sex on women as emasculating, but something men were expect to do. Genital modification itself has to some extent negative connotations everywhere these days, if only because of the influence of Western media, but that has also given rise to a reactionary dynamic that tries to defend these practices using the language of contemporary Western morality, e.g. sex positivity.

> an act that lacks any negative connotations

If you can imagine that forced genital mutilation without anesthetics lacks negative connotations, as long as it's "for her eventual pleasure".

Good Lord.

Do you have examples of this? I read a lot of feminist literature and it's not something that's ever jumped out to me.

Dumb question, why do “sensitive” spots on the body need more nerves? Couldn’t you just have the normal touch-sensing nerves and map signals from specific spots on the body to stronger/pleasurable qualia in the brain?

by Mordisquitos 3 hours ago

Not a dumb question. The shortest (and at a glance unsatisfactory) answer is because it works, and therefore it evolved that way.

Going in detail, first consider that for a feature to be evolutionarily selected for two things have to be true:

1. It must increase the fitness of the organism that carries it, i.e. the likelihood of its carrier having descendants as compared to non-carriers ( or be a side effect of another feature that improves fitness enough to be a net positive, etc etc )

2. It must be inheritable (and, in sexually reproduced organisms, mutually compatible during embryonic development).

One such a feature has reached dominance in a given population, as long as it continues to be important for fitness it cannot really be deprecated in favour of an alternative from scratch, even if that alternative is arguably better.

That's why, for instance, vertebrate ocular nerves connect to our retinas on the inside of our eyeball, resulting in us having a blind spot. Cephalopods, on the other hand, evolved their eyes independently the "reasonable" way, connecing their nerves from behind the eyeball. There's no way a vertebrate could mutate from scratch for its optical nerve to connect to the retina from behind without causing absolute mayhem in embryonic development. Our hacky solution for the blind spot? Let the brain hide it in software.

Going back to your question, some spots of the body being more sensitive than others became critical for evolutionary fitness long before nervous systems were complex enough to generate conscious qualia, let alone enough for them to be consistently involved in decision making. Furthermore, mapping of specific nerves to intensity of feeling on the CNS would imply complex hardcoding of something which is much easier to solve with "this place important, have more nerves", and maybe would even conflict with the fitness benefit of a CNS with enough neuroplasticity to learn anew during the development and lifetime of an organism.

So, in summary, the solution of having more nerves where it matters is simple, good enough, and has no reason to be rolled back in favour of a radically different alternative.

by Fraterkes 3 hours ago

As a software dev, I think this is actually quite a satisfying and sensible answer. A simple reliable hardware solution in favour of a brittle “clever” software one

Having more independent samples helps filter out noise. If you had individual sensory neurons with outsized influence, then misfiring of such neurons would also have outsized influence.

by Fraterkes 4 hours ago

This makes a lot of sense, thx!

by furyofantares 4 hours ago

Sounds plausible at least, but I think the question isn't necessarily making a valid assumption. Why do men have to have nipples? Why is our retina installed backwards? Why do sinuses drain upwards? It's just a path evolution took, it doesn't jump to some optimal design.

by Fraterkes 3 hours ago

Asking “why” questions about our body / evolution often (not always) gives informative answers. As in the example you gave: https://www.scientificamerican.com/article/the-purpose-of-ou...

Interesting finding, though it doesn't explain animals with properly-wired retinas: https://en.wikipedia.org/wiki/Cephalopod_eye

male nipples are developmental vestiges, the male condition is derived from response to embryonic testosterone, and is a developmental variation from default.

early stage embryos of both sexes are not easily distinguishable by genitalia, they look morphologically similar. later developmental events culminate in morphological rearrangement to male form.

lack of response to testosterone during development results n a curious state of affairs, where a person is genetically male, having x, and y chromosomes, develops according to a female plan. external appearances are female, with loss of secondary sex development in puberty.

by technothrasher 4 hours ago

Correct, though interestingly apropos to the discussion is that sex is one of the ways evolution is able to get around local maximums.

by nine_k 4 hours ago

Fingers, for instance, not only have higher sensitivity, but also much higher spatial resolution due to the more dense nerve network.

I can't tell why other areas may have needed higher spatial resolution; maybe it was evolutionary important in the past, and remains today. Or maybe just adding more nerves due to a random mutation correlated with better reproductive outcomes due to a stronger signal, or higher sensitivity, so more nerves are present for no other reason.

by xeonmc an hour ago

Wait, so what you’re saying is, we can use our genitals in a pinch that could be as good as fingers for finesse?

Think of a television. What gives you a better picture, quadrupling the number of pixels or making the existing pixels 4x as intense?

Perhaps encoding "software" is more expensive in terms of codons? So it's cheaper/more likely to "implement" physically.

Page 7 [0] of the report seems to indicate that FGM reconstruction actually seems to have negative outcomes post-surgery. I'm surprised by this. I'm also shocked to see how prolific FGM is too (230 million women?!).

> seems to indicate that FGM reconstruction actually seems to have negative outcomes post-surgery.

> Longitudinal data indicate that approximately 22% of women who undergo clitoral reconstruction experience a post-operative decline in orgasmic experience [25, 26]

From [25] abstract: Most patients reported an improvement, or at least no worsening, in pain (821 of 840 patients) and clitoral pleasure (815 of 834 patients)

So, I think the quote needs to be interpreted as surgery, even though beneficial on average, still having a pretty high percentage of negative outcomes (22%) and nerve mapping potentially helping reduce that.

by thomastjeffery 40 minutes ago

Surgery is essentially mutilation, just with a lot of effort to get the patient a positive outcome. Hopefully, this information will help.

Male genital mutilation is very common

by telesilla 3 hours ago

Respectfully, this article is not about the male experience, it's okay to talk about women without putting men in the story.

by zahlman 2 hours ago

No, it's important context, and attempting to suppress it does everyone a disservice. Without taking these kinds of points of comparison into consideration, one becomes susceptible to https://en.wikipedia.org/wiki/Base_rate_fallacy , and may become convinced about supposed bias where the evidence doesn't support the claim, contradicts it or even shows the opposite.

Another classic example is the discourse around "missing and murdered Indigenous women" in Canadian politics. It was popular enough around a decade ago to be more or less a set phrase. To listen to politicians and wonks discussing the matter, you would imagine that Indigenous men didn't ever get kidnapped or murdered. As a matter of fact, the statistics showed that it happened to them at over twice the rate of the women. (They also showed that it was not an alarmingly high rate compared to other Canadian populations, and that the perpetrators were usually themselves Indigenous — as you'd expect for generally fairly isolated communities.) But you would get silenced in many places (e.g., banned from the Canada subreddit) for pointing to those statistics.

To someone who is shocked at the prevalence of female genital mutilation in other cultures, the widespread acceptance of other types of genital mutilation in (probably) their own culture is an important piece of context, I'd say.

Respectfully, if we didn’t shutter men all the time, maybe there would be paradoxically more time for women. Unless we make it a zero-sum game where we’re all extremists who would lose if it makes the opponent lose too.

Mixed school is a bane for men, for example. I’m full on with the Mollahs on this one.

I know I have assisted in mapping out the full network of nerves of the clitorus, not that it was put quite that way, but the sentiment was there.
