Susan's Place Transgender Resources

So, the sex of a person is influenced by androgen and testosterone exposure as a fetus in the womb.
The ratio of two digits (the comparison of their length) is "considered a crude measure" of that exposure.
There's a theory that orientation and gender may be indicated by that ratio.

In males, the index finger tends to be shorter than the ring finger.
In females the index finger tends to be the same size or slightly longer than the ring finger.

The length is from the bottom crease of the finger to the very tip, so requires measuring, as mere millimeters supposedly indicate a difference. It's also on both hands not just the dominate one.

So far this is merely a uncertain, but well-backed-up, theory, so I was just interested if the people here, women who identify as male, have that verified based on this simple measurement of testosterone exposure.

in my case, my ring fingers are longer than my index fingers on both hands, so I fit the "male" finger ratio.

Here's an article about it:
http://en.wikipedia.org/wiki/Digit_ratio (http://en.wikipedia.org/wiki/Digit_ratio)


Thanks!

...and the good news is that I fit the theoretical female profile.

My index is actually about 2mm longer than my ring.

But i'm still not that convinced by this theory.

It's old and well known but not all transsexuals have it, just like not all non-transsexual people have a normal ratio.

But it really DOES indicate if you had higher androgen or lower androgen levels in the womb, it simply doesn't mean the androgen levels ALWAYS cause a person to orient with one gender or the other.

My index fingers are long, but I am a female, not a ftm. So anyways, so far so good ;)

I did check into it myself sometimes and asked my friends to look when I was in there and sometimes we even asked random people (like a waiter!) because it was funny. So far it was about 95% right ;) Although it's a lot more common for women to vary than for men. (women ratio is about 1.0 with usually the index finger being slightly longer but can be a bit the other way around, men ratio is usually quite larger in favor of the ring fingers).

I think you are more likely to find mtf and ftm with normal ratios for male and female (going the same way). But again, ftm easily varies because women finger digit ratio can vary a lot, but usually is slightly less than me.
I seen men with average of 4 or 5 mm difference and sometimes more, it's rare to see a man with difference of less than 3mm (3mm itself is sometimes rare). At least in my environment.

Right hand index: 7.2 cm
Right hand ring: 7.5 cm

Left hand index: 7.1 cm
Left hand ring: 7.5 cm

Yeah, I'm male. And my hands are tiny, even for a girl, which discounts this explanation in my case:

QuoteA 2009 study in Biology Letters argues: "Sexual differences in 2D:4D are mainly caused by the shift along the common allometric line with non-zero intercept, which means 2D:4D necessarily decreases with increasing finger length, and the fact that men have longer fingers than women,"[8]  which may be the basis for the sex difference in digit ratios and/or any putative hormonal influence on the ratios.

Yah, its unsubstantiated. If you read the article some people even write it off simply as men being predisposed to longer fingers.

They've got it 100% right:

Yah, my hands are tiny too. my fingers are only 7cm as well yet end up with a whole centimeter difference, like this:

Left hand: index-6cm; ring-7cm
Right hand: index-6.3cm; ring-7cm

well as to overall length my Left & Right hands are both the same.

Ring is 6.2
Index is 6.5

I don't know where that places me on the scale of things. I have fairly small palms and proportionally quite long slender fingers.

Just by LOOKING at my hands index finger is shorter (don't have a ruler)

and that puts you comfortably in the female range. Basically, 1:1 or a shorter ring finger indicates female, a longer ring finger indicates male. Men who are close to 1:1 and women who are at or slightly above 1:1 are more likely to be gay.

It's odd, though, I've only met maybe 2 adults in real life with smaller hands than mine, but both of you who've given measurements have shorter fingers than I do. No idea how you manage to find gloves. I wear children's size ones. And not even the largest.

Oh wow! I didn't read into that!

So then in theory I would be attracted to women as a "straight male"?
and are you gay? as in attracted to males as a male-identified person?

ha! how gray is this getting?  :laugh:

but it's not at all unsubstantiated - if you check out the links and sources, there's actually piles and piles and piles of research on the subject. And not just in humans, but in animals too. Not even just primates, either. 2D:4D ratio is one of the most sexually-dimorphic traits visible at birth other than genitalia, and it corresponds with a whole host of sex- and gender-related traits from athletic competitiveness to sexuality to handwriting style, even though it's something that the overwhelming majority of people aren't aware of and thus isn't used to gender people for social conditioning.

Yep.

My left hand is about:
Left Ring: 7.0
Left Index: 7.1

My right hand is about:
Right Ring 7.0
Right Index 7.1
They are pretty a like. I was surprised my left and right measured the same, usually there is quite a bit of asymmetry in left/right of the body.

Wow rejennyrated your fingers are short!

insanitylives, you should probably measure because the fingers usually don't *start* at the same height, so it can make one look longer and when you measure it, you'll find it's shorter. But not to dis-encourage you: it is actually the index finger which starts higher, so if your ring finger is still longer it might just be even more right for you ;)

Fingers aren't the whole hand! how does your palm measure? or let's say base of hand to end of middle finger?

About 17 cm - harder to get an accurate measurement because I'm using measuring tape and I seem to need a third hand to hold it in place.

OH! I was reading the tape wrong when I did my fingers. It's really misleading - the numbers are next to the 0.5cm marks rather than the 1cm marks. Here are the correct measurements:

Right hand index: 6.7 cm
Right hand ring: 7.0 cm

Left hand index: 6.6 cm
Left hand ring: 7.0 cm

I knew the fact that it related to gender, as in genitalia, was true, but that in terms of orientation and gender role it had yet be established as a genuine connection.

What do you think about the left-brain/right-brain argument that states women are more likely to use the left side of their brain?

This images reveals which side is dominant, by the way:

This photo isn't based on how your brain works but rather how your vision works. I saw an explanation for why this photo is flawed, it was very long ago so apologizes for not bothering to find it again.

Anyhow, MOST people will see it rotating clock-wise when looking at it. about 30% of people will see it counter-clock wise because their vision is oriented a bit differently.

Notice if you don't focus on it, for example, focus on a text to the left of it or read the text at the bottom, it should switch sides.

This photo is NOT about the brain sides but rather at the way vision works, which is the same for men and women.

Another thing is, women don't really use the left side of the brain more, women use both of their brain sides at about the same level while men usually use one side a bit more, not always the right or the left, A lot of new arguments actually seem to say that men use their left side more than the right (usually) note: logic, math and science, all at the left side.

feeling, imagination, symbols images and philosophy, right side.

In truth, the use of the brain is mixed, A LOT.

Me too. I have a beautiful pair that were designed for an 11 year old girl - they fit perfectly.

It's rather good - they're cheaper in the Uk because unlike adult clothes they don't carry VAT :)

I never had a male pair - there just wern't any small enough not to fall off!

Yeah my index finger is shorter than my ring finger, on both hands.

There's not really an acceptable definition of "dominant hemisphere," so while the "dancer" image might me measuring something interesting about your brain/perception, it's not likely to be telling you which hemisphere is dominant. (In my case it's counterclockwise, or supposedly "left brain," which may be accurate as I'm a verbal/logic/math person, but I didn't need the test to tell me that.)

Sexual dimorphism of hemisphere dominance is actually a really tricky question to answer. Most people, male and female, are right-handed, which means that in at least some ways the left hemisphere is typically dominant in both sexes. But for some tasks research using brain imaging has shown sexual dimorphism - not in which hemisphere is used, necessarily, but in that women tend to use both at the same time while men's brain activity is concentrated on one side. I think that's supposed to have something to do with sex differences in the corpus callosum.

I have read that too, but that there are definitely consistent areas in which performance is marginally better by women or men, often having to do with spatial recognition, which is why I thought the image might be accurate.

But it is good to know you have seen it debunked, for I won't invest in it any longer!  :)

Neuroscience is so fascinating though. I think its going to do wonders for psychiatric methods and even in the question of consciousness. Looking forward to that!

I find gloves, including women's gloves, are too big for me as well, there is always extra space in the ends of the fingers. Maybe its a finger to palm ratio thing.  :-\

Well that makes three of us wearing children's sizes then... Girls size age 9-11 are what I usually end up with. (and they don't do mechanics gloves in that size either :P )

I've heard about this - and I have a ruler this time. Let's see:

Left index: 7.9cm
Left ring: 8.1cm

Right index: 8 cm
Right ring: 8.1 cm

Yep, I'm male alright ^_^ And I have long fingers considering the size of my hands.

Can't remember my measurements but last time i did this i fell in the male range too

well this is shaping up accurate thus far!

I've looked into this before, too.  I'm got a very male ratio, especially in my left hand.   ;D

Left ring-- 9.1 cm
Left index-- 8.5 cm

Right ring-- 9 cm
Right index-- 8.7 cm

6.5 and 7cm for me.

Can't remember the measurements but I was definitely in the male range as well.

Also am I the only small guy who has no problem fitting in regular men's clothes. I wear small shirts and 29x30 jeans. Maybe it has something to do with my really long arms, big hands...

XS or S shirts here and 28" short jeans.

Nope. S/M in shirts, 30S in trousers/jeans. My hands aren't that big, I'm only 5'4, but I'm also streamlined (long and thin) ^_^

5'2" a 29" leg not telling you the waist  :laugh: and medium to large in the t shirts

To break the pattern, my index finger is longer than my ring finger, which contradicts with my gender identity.  It actually pisses me off, because that will never change.  Apparently, athletic straight men and athletic lesbians tend to have longer ring fingers, whereas less athletic gay men/straight women have longer index fingers.  It actually has less to do with sex, and more to do with orientation.  (From what I have seen/heard).  Seeing as we know gender identity is a large spectrum, male-identified people may have either digit ratio depending upon their sexual orientation.  The same goes for female-identified people.

I know gay people who have normal ratio, so it isn't for gays usually

I was extremely athletic until I was hobbled by puberty. I identify as a gay male, though, so I'm not sure where that should put me on the finger spectrum.

That's actually not entirely accurate. Lesbians and tomboys do often have ratios in the male range, but men (even gay men) very rarely have ratios in the female range. It appears that prenatal exposure to high levels of testosterone at any time during the window when finger length is being established will generate a longer ring finger. And it appears that hormones affect a wide variety of brain structures during that window as well, including ones related to orientation, gender identity, and a wide variety of personality traits.

Well, then, I must be a freak.  ;)  My fingers say I'm perfectly female but it couldn't be farther from the truth.  What I mentioned is only hearsay; I had no idea whether or not it held any truth.

I'm going to have to find a ruler...  My fingers are too close in length to tell if one is longer.  Although, I have what people like to call "piano hands."  Long fingers. :P

I'm 5'7" and I wear (or rather, would, if I could find any!!) 28x34 pants.  The ones I have now are 29x32 and are too short, and sizes have changed since I bought them so that 29" jeans are too big for me now...

Mine are about the same length with the index finger being a little longer. You're not the only one, and I'm guessing the people who don't have the ratio that 'matches' aren't as likely to post on this thread.

Well it's hard to tell, they're pretty much the same although if we're measuring from the crease where finger meets hand I get only very slightly longer ring finger. Looks shorter though.

And. . . you want to know what size pants I wear? Or why is everyone telling their pants size? Anyway 30/32 and I am 5'6".

I figured the pants size thing was about leg length to body length ratio (well, maybe it wasn't, but that was what was on my mind).

yah, the measuring is really important because my fingers look about the same but end up being nearly a centimeter in difference when i measure them because of how they're positioned on my hand.


and for anyone whose fingers don't match up to the ratio, I wouldn't feel bad.
I don't think the lacking measure of higher testosterone levels should mean anything in terms of what someone identifies with, only that it would be likely that many of us would have ratios similar to men.

after all, all of us here didn't get enough of the hormone junk we really needed or else we wouldn't be trans in the first place. lol

Mine is:

Ring: 7.6 cm
Index: 7.2 cm

(These are the long measurements for both hands.  Depending on where I measure from, it can vary by about 2mm less)

Which is interesting.  I swear they look even in length when I look at the back of my hands.

I have nothing to measure with but, my index fingers line up with the top bend on the middle finger and the ring fingers line up with the middle of my nail bed on the middle finger. The ring being longer happens no matter how I turn my hands.

L 1st: 6.6cm
L Ring: 7.5cm

R 1st: 6.5cm
R Ring: 7.6cm

I've heard similar stories about if your 2nd toe is longer than your big toe.  I believe there was an old wives' tale that said if your 2nd toe is longer than your big toe, it means you will be the head of your family.

right index- 8 cm
right ring- 8.8 cm
left index- 8 cm
right ring- 8.8 cm

Yeah, I measured 3 times. I guess I really am ambidextrous. :icon_blink: My left hand (in general) and foot are bigger though which usually shows your dominate side. I did this measurement test awhile ago and I think my fingers have grown longer. That would explain why they feel like growing pains sometimes.

Jamie-o, my family told me the same thing except it would show if you're bossy or not. :D

One possible reason for a masculinized brain in an FTM who wasn't exposed to testosterone in the womb (and therefore has a feminine 2D4D ratio) is that the brain is masculinized via estrogen, not testosterone. Normally estrogen cannot cross the blood-brain barrier, and testosterone can. T crosses over and aromatizes into estrogen, which masculinizes the brain. But this effect can also occur if there is a very high amount of estrogen that overwhelms the alpha-fetoprotein receptors, or perhaps a deficiency in the AFP gene.

fascinating.

Until I came onto this site, I thought all people had longer ring fingers than index fingers. Now I am going to have to check out my sisters and see what they have.

Yeah, I actually do fit the guy hand thing, haha. Then again, I have the frame and figure of a football player naturally. If I remember, I'm supposedly a straight male. *shrugs* On my non-dominant hand the difference is larger... Also, that article said the difference can cause 'masculine handwriting', which has been inescapable all my life, hahaha. I can never fix and make it more legible. (I consider masculine like teenage boy chicken scratch :p)

I agree, if I remember, it only indicates the androgen to the fetus, or some gobbly goo I barely understand because I'm an idiot. It has nothing to do with orientation. However, longer fingers could obviously cause physical things, such as handwriting.

Oh hey. I fit the male one. That just made me happy. I have male hands, so I'm told.

So I had a little bit of an identity crisis because I looked at my hands and my index finger looked longer than my ring finger.  (It is pathetic how easy it is to make me feel like crap over things like this).  However, I actually went ahead and measured them and it turns out my ring finger is about a centimeter longer than my index.  Huh.  You can't always rely on appearances.

Those with Scandinavian heritage will have a more pronounced ratio and those with African heritage will have very little difference.

to be exact, Scandinavian men usually have a bit longer index fingers. Oh hey, it was a bad study though, they made them draw their hand on paper and then measured from the drawing, we already proved in here this is wrong because this only takes the appearance into account and ignores that fingers might start higher or lower.

So the research about Scandinavian men usually having more feminine ratio was shown to be flowed, instead, Scandinavian index fingers usually start a bit higher on average on the hand level.

There is a little line/ridge sort of thing at the base of each finger; you're supposed to measure starting from the middle of these lines.  So yeah, appearance isn't always very telling and it seems that their fingers merely appear longer.  (Maybe I'm Scandinavian. ;))
