Sexual Vitality: A Better Approach
Few topics are of greater interest to my patients than sexuality. And why not? A rich and rewarding sex life is something men and women enjoy and appreciate. But today’s advertising paints a pretty weird picture!
Most of you have seen the barrage of ads on TV and in newspapers and magazines for drugs claiming to cure “E.D” – erectile dysfunction. When I see these relentless ads for drugs like Viagra and Cialis, I always laugh at the fast talking disclaimer at the end, where the announcer (reading a script surely written by the Legal Department) says something like, “Be sure to check with your doctor to make sure you are healthy enough for sexual activity.” The purpose of this disclaimer is to protect the company: if you do get over excited and topple over dead while making love, this careful wording ensures that it’s your family doctor who gets sued rather than the multi-billion dollar drug company.
But it also raises a larger and more

The Anti-Cancer Toolbox
As a physician, there is probably no single question I get more frequently than “What causes cancer – and how can I avoid getting it?”
We human beings always tend to look for that “one elusive thing” that will solve our problems. Even doctors do it. But the reality is that many things in life are made up of many small factors which combine in mysterious ways to produce big results. Cancer is one of those big things. There are many relatively small contributors that “cause” cancer and affect how it grows and spreads, and this complexity is why questions about cancer’s cause and cure are so difficult to answer.
In this blog we’ll focus on a few tips for cancer prevention. In upcoming blogs we’ll consider some supplements you should consider that we believe will help reduce your risk of getting cancer, and also suggest some things you can do if you already have cancer.

Take Mice Studies with a Grain of Salt
Are clinical trials using animal studies always valid for humans? Consider me a skeptic.
I frequently see advertisements and newsletters (even some written by physicians) that promote lab tests and treatments based entirely on studies done using rodents. These “experts” frequently draw conclusions from these studies that their lab test or product is a breakthrough of vital importance to humanity. While it may be true, all too often it’s not.
Let me give you a recent example of a study done in mice that could lead to the conclusion that every woman with breast cancer should be taking very robust doses of the adrenal hormone DHEA. This study should serve both as an encouragement and as a caution, an example of the care we must exercise when we use animal studies to draw conclusions about humans.

Has Science Discovered the Crystal Ball for Cancer?
At Longevity Medical Clinic we often talk to our patients about detecting and preventing cancer. It’s something on the minds of most of us, since we all know that, when it comes to treating cancer, early detecting is critical. One of my patients recently asked me about they had read concerning an early detection test for cancer. Are these tests valid, or do they offer a false hope?
In fact, thanks to advances in early detection, there are now some promising tests for cancer. These tests look for what we call “markers” – early signs of cancer. But the fact is that each cancer has its own specific set of markers, sometimes as many as 30 or 40 that doctors can actually measure. In many cases, in order to get an early detection test that is statistically valid, doctors need to combine 15 or 20 of these markers. You can see how complicated this can get.
Let’s consider one specific example – lung cancer. Almost 5 years ago, medical journals began

The Wrong Way to Do Testosterone
Over the last 25 years, the testosterone level of the average American man has decreased by about 24%. This is almost a 1% per year average decline. We are not just becoming a feminist nation; we are becoming a feminized nation. The reason for this overall decline in male hormone levels is poorly understood, but I suspect that it is related to the widespread presence of estrogenic compounds in our society. Many of the plastics and preservatives used in our day-to-day products and foods have an estrogen like effect on the body.
As the medical profession is becoming more cognizant of the consequences stemming from a diminished testosterone load, an ever increasing number of doctors are starting to use testosterone therapies of one sort or
