Sex Differences in Aging Processes

Dr. Steven Austad, MD, PhD, identifies sex differences in aging as one of the most surprising findings in longevity research. He explains that males and females age differently at a biological level. This fundamental discovery was not anticipated when he began his career. The implications are profound for understanding healthspan and lifespan.

Personalized Medicine for Aging

These sex differences open the door to the first wave of true personalized medicine for aging. Dr. Austad predicts that future anti-aging drugs will likely work differently in men and women. This means treatments could be specifically tailored to help one sex more effectively than the other, moving beyond a one-size-fits-all approach to longevity.

Effectiveness of Late-Life Interventions

Another major surprise for Dr. Steven Austad, MD, PhD, was discovering how late in life interventions can still be highly effective. He previously believed that starting treatments in one's 20s or 30s was necessary for meaningful impact on later-life health. Research now shows that substantial benefits can be achieved even when starting treatments much later in the aging process.

Impact of Exercise and Diet on Aging

Dr. Steven Austad, MD, emphasizes that various interventions can work at advanced ages. This includes medical treatments, exercise programs, and dietary changes. The finding that "it's never too late" to positively influence healthspan is particularly gratifying for Dr. Austad and offers hope for older individuals seeking to improve their quality of life.

Future Directions in Aging Research

Dr. Steven Austad, MD, PhD, looks forward to continued discoveries in anti-aging science. His conversation with Dr. Anton Titov, MD, highlights the rapid evolution of this field. Future research will likely provide more practical actions that people worldwide can implement to extend their healthspan, regardless of their current age or biological sex.

Dr. Anton Titov, MD: Maybe we can conclude our conversation with this question. Could I ask you this: in your decades of anti-aging research, what is the most surprising, the most unusual observation that made you wiser?

Dr. Steven Austad, MD: That's a good question. Am I wiser now than I was then? I think the most surprising thing that I've seen come out of all of the aging research is the sex difference thing. It never entered my mind.

There are two things. That's one of the things: we could have drugs that would specifically help one sex and not the other. I think this will turn out to be the first part of personalized medicine to emerge, as the drugs that are working in females versus males.

But the other surprising thing is how late in life we can start treatments, whether they are medical treatments, exercise programs, changes in diets, and still have a substantial effect on the remaining period of life.

I used to think that if you didn't start these things in your 20s or 30s, it was just too late to have much of an impact on later-life health. We now know that that's not true. It's never too late.

That's the second surprise that I think I would have never suspected. And since I'm older now than I was when I started this, this is a very gratifying thing to discover.

Dr. Anton Titov, MD: Professor Austad, thank you very much for this most helpful conversation. It's most intriguing. We hope to come back to you in the future for more insights into anti-aging research, and perhaps some practical actions that people can do around the world. Thank you very much.

Dr. Steven Austad, MD: Oh, thank you. It's been a pleasure talking with you. Goodbye!
