gene, that's possible, but it's  possibly variety related.
my TC hardy chicago is from hirts n seems to be following the same track as yours.

From what I understand, trees develop fruiting hormones as they mature.  Figs apparently often lose these while undergoing tissue culture.  Not because of the wood where they were collected from (most all of our trees propagated in traditional methods all are from fruiting wood) but just because they are taken from tiny shoots that are further divided.  Once a tissue culture line is established, future generations continue to be taken from these very tiny shoots being grown in dishes.

Here's a pretty poor quality video I shot while on tour at Duarte Nursery several years ago.  I believe they may be doing figs now.  At the time of the tour they had winegrapes, citrus, almonds, pistachio, stonefruit, etc.

Hi,
Unless going from seeds, a young figtree doesn't exist. They are all propagated by cuttings, which is the easiest way.
So they are all coming from "old trees".
If you have a tc- hardy chicago, the cells were taken on such "an old tree" - or then the tree is no longer Hardy Chicago.
With seedlings, the resulting trees should not be true to type.

I don't see why tc-cultured trees would be any different from cuttings - but I'm lacking observations on such a tree - so I'll have to believe you.

It could be that people buy fig trees not adapted to their zone and thus they don't see any figs.

Let me tell you the story about a tree I have :
A friend swapped cuttings with a guy, and the resulting tree has been in his garden for some 12 years.
I could see brebas for the first time last year and they all dropped.
The tree has brebas this year if she will be dropped if they drop !
I asked the friend to wait this year more as the weather has been mild. That tree never was fertilized and never is watered in a zone where sun strikes hard on Summer.
So this is a tree generated from cuttings that has not produced any edible for 12 years ! But ok, the tomato growth season there is a month shorter than suitable, hence the poor results.

That tree has been driving me crazy, and I decided in October 2011 to take 3 cuttings to my garden (I know because those bloody stick could survive February 2012 where 6 of my trees died !).
The rodents attacked the tree, and I dug them up and installed them in an 80 liters trashcan with no bottom in June 2012.
Of course, one died, and I'm left with 2 trees .
The trees are now 2 full years old ... Where are those damn figlets ?
As of yesterday, I still haven't seen a figlet on those trees - the season is not over yet of course.
Those trees are watered and fertilized. They are at 1,50 meter of height.
So just a cheesy strain . I called that strain the "perhaps brunswick" because the leaves do resemble the ones of "Brunswick".

But you just gave me a idea. My cuttings were taken at dirt level and I'll have to airlayer the tree and see if that makes a difference ! - That is, if I don't get any figs on mine this season of course.

My tissue cultured Violette de Bordeaux, pictured in post #3 is currently producing figlets, its less that 1 year old. Its too late in the season for them to mature, but it bodes well for next season.

Great topic, I had questions about TC myself. Bought a few live figs from eBay and one from Well Springs. Good info everyone. 

Thanks for the additional information Pete, this is very encouraging news.
