My oldest cresties 1.2 were hatched in late '96, I got them when they were just a couple months old, Jan (or was it Feb?) '97. They are all still breeding up a storm, males and females. Their various kids that I kept back are still breeding, though they'd have been hatched in 99 and later. The females show no signs of slowing down, no increase in infertile eggs, no poor physical shape, no lethargy, nothing to say they're into menopause or being pushed too much to breed. The girls look just as good as they do in older pictures.
My original gargoyle females are retired, the females don't generally lay fertile eggs after about 6 years. I've still got all the girls, they're living in a retirement condo ( 75 gallon tank just for the 3 of them). The oldest male is still fertile, but then you wouldn't expect a male to be worn out at 7 years, their contribution to breeding isn't as demanding on their bodies. If and when he retires, I'll set him up in a condo too, but smaller for himself (though I might try to see if he'll safely live with the girls ... all the fun with out the guilt and fallout

)
