Here’s an eye-opening TED talk on this topic:

I ask them if they’d like to watch *River Monsters *and *Turtle Man *with me.
If no then woman.
No wonder we have so many innocent folks in prison… 
By that same reasoning, put on a *Three Stooges *short. If they laugh uproariously, they are a man. If they sniff and look away – chick.
I think gender recognition is very facially oriented. I can’t think of a time where I saw a face and was mistaken of it’s gender. While of course there are individual exceptions, men have more prominent jawlines and angular features; while womens’ faces are typically softer and less severe. Also, the presence of facial hair-roots, whether there is actual hair or it’s been shaved, makes a difference.
“Finally, there could be some individuals in the audience who really don’t give a F**** about the beauty pageant, because beauty itself is subjective”
And this is neither here nor there but I just wanted to add that I don’t believe anyone would be in a beauty pageant audience who really didn’t give a FUCK about the beauty pageant. At least not voluntarily. 
Hubba hubba! All right, seriously, then I guess she’s a man. (I refuse to change my metric, no matter how idiotic it is in retrospect.)
No, they don’t. Go back and read that article, it’s written entirely in theoretical terms.
And why can’t you hold a human being upside-down and look between the legs? Only .15% of live births result in genitalia ambigious enough to make them medically interesting. Or were did you mean can’t as in “you can’t treat people that way!”?
I’m gonna go out on a limb and guess he was referring to the latter.
Well then he can say so. But he’s wrong. It’s always worked for me.
And now you know why he wears a beard.
I personally find that most men want to make sure you know they are male and most women want you to be sure they are female. People don’t like being addressed as the wrong gender. The exceptions aren’t going to mind if you get it wrong.
Transvestites are very, very good at making you think they are female. But, they can’t hide the protruding adams apple.
Look at the base of the neck. Men always have protruding adams apples. If the cute lady has an adams apple then you’re in for quite a shock if you take them home. 
The first thing I notice is breasts, or lack thereof. If a peripheral breast-reading is inconclusive, I look at hair length/face/jewelry, then shoes, then manner of dress. If I’m still confused at this point, voice is a pretty good final indicator.
Body shape, hair length, voice, facial construction and hirsuteness are all aspects that are taken into account. If these fail, and sometimes they do; I’ve run into a couple of people whose names do not clarify their gender and in those cases, I simply default to they/them when discussing them in absentia and using friend/their name when I need their attention. I find not knowing someone’s gender in absolute terms is not really that big a hindrance.
Pat.
Bwa-ha-ha-ha-ha!.. <snort… snicker… sputter… cough… gasp… wheeze>
(bolding mine)
Not without buying them a couple of drinks first, at least! 
- hair (including facial)
- clothes
- if still ambiguous, breasts/bra/adam’s apple
Good job misrepresenting the information in that article. Considering we can’t, at least from that information given, discern where the line is for where medical experts consider surgery feasible or necessary (the latter a gross concept in itself). For those who want an honest figure, it says 1% of live births include some kind of ambiguous genitalia.
And also, you know, some people are transgender and have genitals that do not match their outward gender representation. But you know, apparently when a group is a small percentage of the population, it’s okay to just disregard them entirely!
ps, aceplace57, not all males have prominent adam’s apples.
No, thank you. 
I think we all know that there’s nothing, simply nothing, that can tell you for every single individual - particularly if intersexed, transgendered and/or cross-dressing people are in play.
But, that being said, if I’m trying to figure out the gender of an ambiguous individual (which usually means their body shape doesn’t make it immediately obvious), I find I first notice facial bone structure, then contrast between lips and skin on the face (women tend to have more contrast, even without makeup), then facial skin texture (testosterone makes skin thicker and pores more noticeable) then presence/lack of facial hair, then Adam’s Apple, then hand shape and texture.
Basically, I look for the masculinizing effects of testosterone and other androgens.
There’s also finger length. In most cases, men have a ring finger that is second in length only to their middle finger, while women have their index finger as their second longest. It’s easiest if you look at the back of the hand, not the palm side.
This isn’t foolproof, but it’s usually correct. It’s saved me from taking home more than one transvestite!
