Actually, it should produce fruit. But to date, nobody has recorded seeing fruit yet. Its possible somebody did, but didn't know it was an important event. If you are lucky enough to have one fruit, it is critical that you take photos, and then preserve the fruit in grain alcohol, minimum 70% by volume (70% ethanol, booze). Add a couple drops of glycerine to the alcohol before pickling the fruit. Actually about 1 to 2 % glycerine by volume. This will preserve the flexibility of the specimen. Then get copies of the photos & a sample of fruit to Jerry Meislik. There are a couple candidates known from the wild, that we have not been able to narrow down. Fruit is the key botanical trait that separates all Ficus species.
The alcohol-glycerin mix is what botanic herbaria use to preserve specimens where they want to preserve the 3 dimensional structure that is normally lost when a specimen is pressed flat in your "old fashioned" herbarium specimen.
