A Harvard Specialist shares his thoughts on testosterone-replacement Treatment

 

An interview with Abraham Morgentaler, M.D.

It might be stated that testosterone is the thing that makes guys, men. It gives them their characteristic deep voices, large muscles, and facial and body hair, distinguishing them from women. It stimulates the development of the genitals , plays a role in sperm production, fuels libido, and leads to regular erections. It also fosters the production of red blood cells, boosts mood, and aids cognition.

Over time, the testicular"machinery" that makes testosterone gradually becomes less effective, and testosterone levels start to fall, by about 1% a year, beginning in the 40s. As men get into their 50s, 60s, and beyond, they might begin to have symptoms and signs of low testosterone like reduced libido and sense of energy, erectile dysfunction, diminished energy, decreased muscle mass and bone density, and nausea. Taken together, these symptoms and signs are often referred to as hypogonadism ("hypo" significance low working and"gonadism" referring to the testicles). Researchers estimate that the illness affects anywhere from two to six million men in the USA. Yet it is an underdiagnosed problem, with only about 5% of those affected receiving treatment.

Much of the current debate focuses on the long-held belief that testosterone may stimulate prostate cancer.

Dr. Abraham Morgentaler, an associate professor of surgery at Harvard Medical School and the director of Men's Health Boston, specializes in treating prostate ailments and male reproductive and sexual problems. He has developed particular expertise in treating lower testosterone levels. In this interview, Dr. Morgentaler shares his perspectives on current controversies, the treatment strategies he uses with his own patients, and he believes specialists should rethink the potential link between testosterone-replacement therapy and prostate cancer.

Symptoms hop over to here and this postpop over to these guys diagnosis

What symptoms and signs of low testosterone prompt that the average man to find a physician?

As a urologist, I tend to see guys because they have sexual complaints. The primary hallmark of low testosterone is low sexual libido or desire, but another may be erectile dysfunction, and any guy who complains of erectile dysfunction must get his testosterone level checked. Men may experience different symptoms, such as more trouble achieving an orgasm, less-intense climaxes, a lesser quantity of fluid from ejaculation, and a sense of numbness in the penis when they see or experience something that would usually be arousing.

The more of these symptoms there are, the more probable it is that a man has low testosterone. Many physicians tend to discount these"soft symptoms" as a normal part of aging, but they're often treatable and reversible by normalizing testosterone levels.

Are not those the very same symptoms that men have when they are treated for benign prostatic hyperplasia, or BPH?

Not exactly. There are a number of drugs that may lessen sex drive, such as the BPH drugs finasteride (Proscar) and dutasteride (Avodart). Those drugs may also decrease the quantity of the ejaculatory fluid, no question. However a reduction in orgasm intensity normally does not go together with treatment for BPH. Erectile dysfunction does not ordinarily go along with it , though surely if somebody has less sex drive or less attention, it's more of a struggle to get a fantastic erection.

How do you decide whether a person is a candidate for testosterone-replacement therapy?

There are just two ways that we determine whether someone has low testosterone. One is a blood test and the other one is by characteristic symptoms and signs, and the correlation between those two methods is far from ideal. Generally guys with the lowest testosterone have the most symptoms and men with maximum testosterone have the least. However, there are some guys who have low levels of testosterone in their blood and have no symptoms.

Looking at the biochemical numbers, The Endocrine Society* believes low testosterone to be a entire testosterone level of less than 300 ng/dl, and I believe that's a sensible guide. However, no one quite agrees on a few. It's not like diabetes, in which if your fasting sugar is above a certain level, they will say,"Okay, you've got it." With testosterone, that break point isn't quite as clear.

*Notice: The Endocrine Society recommends clinical practice guidelines with recommendations for who should and shouldn't receive testosterone treatment.

Is total testosterone the ideal thing to be measuring? Or should we be measuring something different?

This is another area of confusion and great discussion, but I do not think it's as confusing as it appears to be from the literature. When most physicians learned about testosterone in medical school, they learned about total testosterone, or all the testosterone in the human body. However, about half of their testosterone that's circulating in the bloodstream isn't readily available to the cells. It's closely bound to a carrier molecule known as sex hormone--binding globulin, which we abbreviate as SHBG.

The biologically available part of total testosterone is known as free testosterone, and it is readily available to cells. Nearly every laboratory has a blood test to measure free testosterone. Even though it's only a little portion of this overall, the free testosterone level is a pretty good indicator of low testosterone. It's not perfect, but the significance is greater compared to testosterone.

This professional organization urges testosterone treatment for men who have

  • Low levels of testosterone in the blood (less than 300 ng/dl)
  • symptoms of low testosterone.

Therapy is not Suggested for men who've

  • Breast or prostate cancer
  • a nodule on the prostate which may be felt during a DRE
  • a PSA greater than 3 ng/ml without further evaluation
  • a hematocrit greater than 50% or thick, viscous blood
  • untreated obstructive sleep apnea
  • severe lower urinary tract symptoms
  • class III or IV heart failure.

Do time of day, diet, or other factors affect testosterone levels?

For years, the recommendation was to receive a testosterone value early in the morning since levels begin to fall after 10 or even 11 a.m.. However, the information behind this recommendation were attracted to healthy young men. Two recent studies demonstrated little change in blood glucose levels in men 40 and mature within the course of this day. One reported no change in typical testosterone till after 2 p.m. Between 2 and 6 p.m., it went down by 13%, a modest amount, and probably not enough to influence identification. Most guidelines nevertheless say it's important to do the evaluation in the morning, but for men 40 and above, it probably doesn't matter much, as long as they get their blood drawn before 5 or 6 p.m.

There are some rather interesting findings about dietary supplements. By way of example, it appears that individuals who have a diet low in protein have lower testosterone levels than men who consume more protein. But diet has not been studied thoroughly enough to create any clear recommendations.

Within the following guide, testosterone-replacement treatment refers to the treatment of hypogonadism with exogenous testosterone -- testosterone that is manufactured outside the body. Based upon the formula, treatment can cause skin irritation, breast enlargement and tenderness, sleep apnea, acne, decreased sperm count, increased red blood cell count, along with additional side effects.

Within four to six months, each one of the men had heightened levels of testosterone; none reported some side effects during the year they had been followed.

Because clomiphene citrate isn't accepted by the FDA for use in men, little information exists regarding the long-term ramifications of taking it (such as the probability of developing prostate cancer) or whether it's more capable of boosting testosterone than exogenous formulas. But unlike exogenous testosterone, clomiphene citrate preserves -- and potentially enhances -- sperm production. This makes medication like clomiphene citrate one of just a few choices for men with low testosterone that want to father children.

Formulations

What kinds of testosterone-replacement therapy can be found? *

The oldest form is an injection, which we use since it's inexpensive and because we faithfully get fantastic testosterone levels in nearly everybody. The drawback is that a man should come in every few weeks to find a shot. A roller-coaster effect can also happen as blood testosterone levels peak and return to research. [See"Exogenous vs. endogenous testosterone," above.]

Topical treatments help maintain a more uniform amount of blood testosterone. The first kind of topical therapy has been a patch, but it has a very large rate of skin irritation. In one study, as many as 40 percent of men who used the patch developed a reddish area on their skin. That restricts its use.

The most widely used testosterone preparation in the United States -- and the one I begin almost everyone off with -- is a topical gel. The gel comes in tiny tubes or in a unique dispenser, and you rub it on your shoulders or upper arms once a day. Based on my experience, it has a tendency to be absorbed to good degrees in about 80% to 85% of guys, but leaves a significant number who don't absorb sufficient for it to have a favorable impact. [For specifics on several different formulations, see table below.]

Are there any downsides to using gels? How much time does it take for them to work?

Men who begin using the gels have to return in to have their testosterone levels measured again to be sure they are absorbing the right amount. Our goal is the mid to upper range of normal, which generally means around 500 to 600 ng/dl. The concentration of testosterone in the blood really goes up quite quickly, in just several doses. I usually measure it after two weeks, even although symptoms may not change for a month or two.
