Research says, Bitches that keep their ovaries live longer, according to new research study headed by David J. Waters D.V.M., associate directer of Purdue University's Center on Aging and life Course, and a professor in the Department of Veterinary Clinical Science in West Lafayette, Indiana.
In and article title, "Exploring Mechanisms of Sex Differences in Longevity: Lifetime Ovary Exposure and Exceptional Longevity in Dogs", published in December 2009 (vol. 8, Issue 6) edition of the journal Aging Cell, Waters and his team document a link between retaining ovaries and reaching exceptional longevity in mammals - the first investigation of its kind.
Researchers collected and analyzed lifetime medical histories, ages and causes of death for 119 long-lived Rottweilers in the United States and Canada that survived to 13 ears, which is 30 percent longer than average. They were compared to a group of 186 Rottweilers that lived to an average 9 years. "A female survival advantage in humans is well-documented - women outnumber men by 4-to-1 among those who reach100" Waters says. "Like women female dogs in our study had a distinct survival advantage over males. But taking away the ovaries during the first four years of life completely erased the female survival advantage."
The researches found that female Rottweilers that keep their ovaries for at least six years were four times more likely to live exceptionally long compared to females that had their ovaries removed at a young age.
"The data from women and dogs, together with reported longevity benefits from ovary transplants in mice, are pointing in the same direction - the notion that a network of processes regulating longevity us under ovarian control," Waters says.
