Frailty tool in aging dogs digs up new data energizing the maternal cost of reproduction debate: Good news for mothers

Researchers found that females with live offspring had lower late-life frailty, contradicting previous theories on a potential reproductive cost. The study used companion dogs to investigate the relationship between reproduction and aging, revealing a unique link between parity and robustness.

Message from the oldest-living dogs to dogs and men: Gonad function fights frailty

A study by the Gerald P. Murphy Cancer Foundation's Center for Exceptional Longevity Studies found that retaining gonad function can significantly impact frailty mortality risk. Male dogs with shortest testis exposure had high mortality risks, while those with longest gonad exposure showed no consequence of increasing frailty.
