Show it porn and see if it gets an erection? All I know is the females trees have been banned locally. Nasty smelling fruit like only the female is to blame.

If it bears smelly fruit (or technically its supposedly not fruit, but people call it that) its female. If it produces small pollen cones its male.

en.wikipedia.org

Of course you would see these things well after it's already been planted, so it probably doesn't help much.

Also the male plant produces the pollen, but if the female plants are really smelly that might be a better option, unless your particularly allergic.

More on the smell

"One day last summer on a stroll down 66th Avenue in Oakland, a smell brought me back to a short street (one block) in the South End neighborhood of Boston, Massachusetts, lined with a single tree species. The smell and the tree: the ripe fruit of the female ginkgo tree (Ginkgo biloba). It was pungent; for me, a cross between a rotten apricot and vomit."

"I mentioned that the fruit releases its odor when it is bruised or crushed (triggering the decay process), so the malodor could be mitigated by harvesting the fruit."

localecology.org

That odor doesn't sound at all appealing

And even if you can largely avoid it by harvesting, then apparently you would have to dispose of the fruit without bruising or crushing it first. You could eat it, it is edible, but even if doesn't smell as you eat it (because it needs to decay before it really starts smelling) I'm not sure you would want to have to eat a lot of ginko fruit/nuts quickly when they start to become ripe. Also apparently if you don't get the fruit in time, you get the smell, so you would have to be vigilant about it.

How, pray tell, can one tell the difference between a male and a female ginko tree?

The Made in China method seems to be the macro way to do it - plant a few and kill off the sex you don't want: <Gender: the tree is dioecious, male and female trees are separate. The sex chromosomes (XX females and XY males, just like humans) are difficult to distinguish, so the tree's gender is not easily classified.
The pollen and ovules grow on the short spurts, very seldom on the leaves (Ohatsuki). Occasionally both genders are found on the same tree.
After a hot summer or grown in a warm sunny position the tree produces them more reliably.
The female tree has an abundance of ovules in pairs on stalks each containing an egg cell, looking very green on the start but turning into greenish-yellow followed by orange and brown.

If you choose a whole lot of males, at least they won't form themselves into an army and go on the rampage.

That was after a brief quizz of Google. There is probably a more sensible method.

You could get a microscope and look for a Y chromosome and plan t the trees without them. That would be more ethical.

This is a combination of male answer syndrome and stalking. I forget how I ended up there, but I followed a trail of posts which led to Edwarda, deceased, and Neocon deceased, which led me to a randomized clicking, so I clicked a couple of names to see what their latest posts were and hey presto, there you were. You and Rambi and others were posting back in 1999 [which is the era in which I was clicking - SI has such a lengthy history now, but unfortunately, quite a few histories stopped].

Aha, here is where I started... siliconinvestor.com I was just doing a daily click through a bunch of posts and go side-tracked there.

Anyway, back to work clicking. Now I know a little about butyric acid stink from ginkgo tree "fruit" which is not really a fruit.

As a passing thought, the world's economic collapse and geopolitical situation can't be all that bad if I'm goofing around like this. Though Nero fiddled while Rome burned [so they say].
