Summary

Story summary

A study of aging male Rottweilers shows maintaining testicular hormone signaling reduces frailty and mortality risk.
Researchers tracked 87 dogs aged 13 and older in West Lafayette, Indiana, linking longer testis exposure to better survival.
Neutering early correlated with higher frailty-related mortality, while prolonged gonad function indicated resilience.
The findings, published in Scientific Reports, may inform human aging by linking hormonal disruption to frailty in older men.
