Can taking vitamins and supplements over the long term impede the body's ability to produce it's nutrients if the supplements or vitamins are stopped suddenly?

Common misconceptions (we are trying to get over these remember guys!!!) exogenous testosterone will shrink the testes temporarily, as they naturally produce test which is obviously down-regulated down during this period. However upon ceasing therapy the testes will go back to normal size. Penis is unaffected, except in adolescents where it will increase Penis size ;)

or do take testosterone if you keep tripping over your penis.

good to know, but what can reverse shrinkage even if no testosterone has been taken(no offense implied

Testosterone is known for doing this. It's really a bit scary and causes things like errr...shrinkage. So dudes, don't ever supplement testosterone.

Taking essential vitamins and minerals will not impede production because the body already cannot produce those. That's why they are called essential.

Consumption of other things that your body already produces, like glucosamine, might effect body production levels or it might not. You would have to look at each thing on a case by case basis. Usually what can happen is long term consumption can result in the body producing less on it's own. So if you supplement long term, you should taper off and allow your body time to ramp up production again, instead of quitting the supplement suddenly. Rarely have I heard of the body permanently losing its ability to produce, but apparently long term, there have been some cases of the producing parts of the body atrophying. Again, you would need to research each thing on a case by case basis.

It seems they can have a negative effect, according to this study (full text):

from the abstract:

"Consistent with the concept of mitohormesis, exercise-induced oxidative stress ameliorates insulin resistance and causes an adaptive response promoting endogenous antioxidant defense capacity. Supplementation with antioxidants may preclude these health-promoting effects of exercise in humans."

(I know that this is not exactly the answer to your question, but still relevant, I think)

Short answer: No, not for vitamins and minerals which are only ever acquired exogenously through diet.
