Can Good Sex Keep You Young?


WebMD Feature

Nov. 13, 2000 -- When I asked my 77-year-old friend Peter Kranz of Darien, Conn., about his sex life, he was immediately forthcoming. "We make love twice a day," he said.

"You do this every day?" I asked.

Diabetes Power Foods: Whole Grains and Fiber

Imagine this food: It's low in calories. It makes you feel full. And you can eat as much of it as you want. Too good to be true? It's fiber and it is real. You can find it in fruits, vegetables, legumes, nuts, and whole grains. Most everyone should eat more fiber -- especially if you have diabetes. Even though fiber is a carbohydrate, your body can’t break it down. This means you don’t digest fiber, and it doesn't raise your blood sugar. And as fiber moves through your body, it helps with digestion,...

"The schedule is not written in stone," Peter explained. "But we do make love every day."

Michael Roizen, MD, would say that sex is keeping Kranz young. In his best-selling book, RealAge -- Are You as Young as You Can Be?, Roizen makes the case for the antiaging effects of sex after surveying the available literature. "Having sex at least twice a week can make your RealAge 1.6 years younger than if you had sex only once a week," Roizen says. He defines 'real age' as "an estimation of your age in biologic terms, not chronologic years."

Although Roizen's statistics are sketchy, he derives his figures primarily from a study done in Caerphilly, Wales, and published in the December 1997 British Medical Journal under the title, "Sex and Death: Are They Related?" One of the few efforts to examine the relationship between sex and mortality, the study found that men who reported at least two orgasms a week at the time of the study had less than half the risk of dying from various causes over 10 years of follow-up than those with a lower frequency of orgasm. Drawing on the researchers' remark that the evidence suggested a dose-response relationship -- meaning in this case that the more orgasms a man had, the longer he lived -- Roizen concluded that someone like my friend Peter, who has sex every day, could have a Real Age as much as 8 years younger.

At first blush (and Peter's candor did make me blush), my friend is a convincing example of Roizen's argument. He is youthful-looking, energetic, and actively involved in many interests. Peter still works as a developer of computer systems. He has had a steady, positive relationship with his wife who, at 77 also, still commutes to Manhattan for her own job at a major nonprofit institution.
