Naked Mole Rat and Fertility

EurekAlert! drew my attention to this study on the fertility of naked mole rats.  Females demonstrate no decline in fertility for the majority (perhaps all) of of their decades-long lifespan.  From the news item:  

“Naked mole-rats are the weirdest mammals,” said lead author Miguel Brieño-Enríquez, M.D., Ph.D., assistant professor at Magee-Womens Research Institute and the University of Pittsburgh School of Medicine’s Department of Obstetrics, Gynecology and Reproductive Sciences. “They’re the longest-lived rodent, they almost never get cancer, they don’t feel pain like other mammals, they live in underground colonies, and only the queen can have babies. But to me, the most amazing thing is that they never stop having babies — they don’t have a drop in fertility as they age. We want to understand how they do this.”
