Testosterone and Aging

Admin

When you think of testosterone, what comes to mind? Macho men? Aggressive, impatient, type A behavior? Road rage? Violence? Testosterone’s role in bad behavior is largely a myth. What’s more, testosterone plays other important roles in health and disease. Testosterone is a key player in Prostate cancer. Women need testosterone too.

Testosterone: What it does and what it doesn’t do

Testosterone is the major sex hormone in males. It is produced by testis. Signals sent from the brain to the pituitary gland at the base of the brain control the production of testosterone in men. The pituitary gland then relays signals to the testes to produce testosterone. A “feedback loop” closely regulates the amount of hormone in the blood. When testosterone levels rise too high, the brain sends signals to the pituitary to reduce production.

Testosterone plays several important roles in males:

Does women have testosterone?

Testosterone also plays important role in females. Testosterone is produced in the ovaries and adrenal gland in females. These hormones are thought to have important effects on:

The proper balance between testosterone (along with other androgens) and estrogen is important for the ovaries to work normally. While the specifics are uncertain, it’s possible that androgens also play an important role in normal brain function (including mood, sex drive and cognitive function).

Did you know?

Testosterone is synthesized in the body from cholesterol. But having high cholesterol doesn’t mean your testosterone will be high. Testosterone levels are too carefully controlled by the pituitary gland in the brain for that to occur.

Testosterone levels at different ages

Testosterone levels are at their highest during adolescence and early adulthood. In boys, the first physical signs of testosterone, or androgens, in the body are apparent during puberty. A boy’s voice changes, his shoulders broaden, and his facial structure becomes more masculine. As men get older, their testosterone levels may decline about 1 percent per year after age 30.

Normal Testosterone Levels

The “normal” or healthy level of testosterone in the bloodstream varies widely, depending on thyroid function, protein status, and other factors. According to recent guidelines from the American Urological Association (AUA), a testosterone level of at least 300 nanograms per deciliter (ng/dL) is normal for a man. A man with a testosterone level below 300 ng/dL should be diagnosed with low testosterone.

Excess testosterone in men can result from testicular or adrenal tumors. These tumors can be non-cancerous, yet still boost testosterone levels to unhealthy levels, as can steroid use and testosterone abuse. Some men actually have a genetic predisposition for developing high levels of testosterone. These men are at a much higher risk for developing blood clots, heart disease, and a variety of other cardiovascular issues.

Problems associated with abnormally high testosterone levels in men include:

High Testosterone and Risk Of Metabolic Disorders and Cancers

It is essential that men with high testosterone are tested and are aware of their potential risks.

Did you know?

Women can have high testosterone levels.

Among women, perhaps the most common cause of a high testosterone level is polycystic ovary syndrome (PCOS). This disease is common. It affects 6% to 10% of premenopausal women.

Natural Ways To Boost Your Testosterone

TESTOSTERONE IS THE CRUCIAL MALE HORMONE IN THE HUMAN BODY. UNDERSTANDING ITS EFFECTS AND KNOWING HOW TO BOOST ITS LEVELS HELPS BOOST PHYSICAL FITNESS.
If you want to boost your natural testosterone levels, it helps to know all the best strategies — both in and out of the gym.

A. Boost Testosterone with Exercise

“Training to build muscle mass elevates testosterone, and elevated testosterone helps build muscle mass.” Just make sure you don’t do too much. When you overdo weight training and go past the point, instead of elevating testosterone, you boost stressful cortisol levels, which can reduce your muscle mass and testosterone levels. To maximize testosterone levels, include the following exercise strategies.
1. Train smart with weights
Keep hardcore weight-training sessions to 4–5 per week, and finish workouts in 60–75 minutes. Emphasize sets that max out at 5–8 reps, and reduce rest periods to about two minutes between sets to include more sets in a shorter time span.
2. Keep your cardio moderate.
Perform moderately paced cardio such as an easy jog or fast-paced walk on a treadmill. Sessions should not be longer than 30–45 minutes, and no more than about four a week, especially when you’re trying to add muscle mass.

B. Boost Testosterone with Nutrition

Certain dietary adjustments help you naturally boost your testosterone levels.
1. Consume plenty of protein.
Consume at least 1 gram of protein for each pound of your bodyweight every day, and strive to get in about 30% of your total calories from protein each day.
2. Consume cruciferous vegetables.
“Research has shown that consuming a diet rich in cruciferous vegetables such as broccoli, cabbage, brussels sprouts, collards, watercress, kale, kohlrabi, mustard greens and bok choy may help boost testosterone levels.” This is due to the phytonutrients they contain, including indoles, which help suppress estrogen.
3. Eat plenty of fats.
Saturated fats, which are considered “unhealthy”, provide the raw materials your body needs to produce hormones such as testosterone. 10% of your daily calories may be consumed in the form of saturated fats. In addition, 10% of your daily calories should be from unsaturated fat sources such as oils (olive and canola) and fatty fish (salmon. In total, dietary fat should constitute 20% of total caloric intake.
4. Grapes
Grapes contain many vitamins that contribute to overall health. Chinese researchers have found that 5-10 g of grape skins improves sperm motility and increases testosterone levels.
5. Avoid alcohol.
Keep alcohol consumption to no more than 1–2 drinks per day.
6. Other food items that boost Testosterone.
Egg yolk, beef, shell fish, fatty fish, tuna, oysters, extra virgin olive oil, pomegranates, fortified plant milks, onions, green leafy vegetabes, garlic, beans are some other food items that may naturally boost testosterone production.

C. Boost Testosterone with Supplements

Certain supplements taken daily like cordyceps (from mushrooms, 300-450mg), Tribulus terrestris (from a herb growing North America and Asia, 500-2000 mg), fenugreek (500-600mg), ginseng (40-50mg twice a day) can help in boosting testosterone levels naturally. 30 mg per day of Zinc supplements showed an increase in free testosterone levels

D. Lifestyle Strategies for Increased Testosterone.

1. Get plenty of sleep.
Get at least 7–8 hours of sleep per night, striving for the high end on days when you train harder such as when doing legs or back.
2. Schedule days off from the gym.
At least once a week give your body a full day of recovery with no weights, cardio or any other stressful forms of activity.
3. Have sex regularly.
With a partner or alone, frequent ejaculation boosts testosterone levels, which in turn works your endocrine system, helping to keep it primed.

Low Testosterone

‘When I was in my 20s I went through my testosterone phase and had a Mercedes to show that I’m rich, and they used to call me ‘Jaguar John.’ I’m older now, and I’m concerned about the environment and… appreciate a car that doesn’t pollute.’
– John Densmore
Low testosterone (male hypogonadism) is a condition in which the testes (testicles, the male reproductive glands) do not produce enough testosterone.

Causes Of Low Testosterone

Common causes include:
Some persons are born with conditions that cause Testosterone Deficiency (TD) such as:

Some men may develop Low-T because of conditions like these:

Basically, if your testicles keep making less testosterone than normal, your blood levels of testosterone will fall. Many men who develop TD have Low-T levels linked to:

Men with certain health problems also tend to have low testosterone. Some of these are:

How Common is Low Testosterone (Low-T) in Men?

It is hard to know how many men among us have Low-T, although data suggest that overall about 2.1% (about 2 men in every 100) may have Low-T. As few as 1% of younger men may have TD, while as many as 50% of men over 80 years old may have Low-T.

Low-T is more common in men who have diabetes or who are overweight. In one research study, 30% of overweight men had Low-T, compared to only 6.4% of those with normal weight. The same study found diabetes to be a risk factor for Low T. In another study, 24.5% of men with diabetes had Low-T, compared to 12.6% of those without diabetes.

Can low testosterone be prevented?

There are no known ways to prevent low testosterone that is caused by genetic conditions or damage to the testes or pituitary gland.

A healthy lifestyle that includes good nutrition, exercise, weight management, and that avoids excessive use of alcohol and drugs can help keep testosterone levels normal.

Did you know?

Not all patients who are found to have low testosterone need to be treated.

Male Aging/ Andropause / Androgen deficiency in aging male/ Late-onset hypogonadism

What is Andropause?
“Andras” in Greek means human male and “pause” in Greek a cessation; so literally “andropause” is defined as a syndrome associated with a decrease in sexual satisfaction or a decline in a feeling of general well-being with low levels of testosterone in older man.

It is a common disorder, affects an estimated 1 in 200 men.

History of Male Menopause

Testosterone deficiency was originally conceptualized in the Talmud and Old Testament. A 16th century medical text found in China listed symptoms relating to the ideology of the male menopause syndrome. In 1944, Heller and Myers wrote what was considered a milestone paper in understanding the reversal of testosterone deficiency by testosterone replacement.

What are the symptoms of low testosterone?

Symptoms of low testosterone depend on the age of person, and include the following:

Other changes that occur with low testosterone include:

How is low testosterone (Low-T) diagnosed?

To make a diagnosis, your doctor will assess specific signs and symptoms in addition to your testosterone blood level. It may take several measurements to determine if a patient has Low-T, since levels tend to change throughout the day. The highest levels of testosterone are generally in the morning, near 8 a.m. This is why doctors prefer to measure testosterone levels in the early morning.
Additional tests that may be advised based on your clinician’s assessment include

How is low testosterone treated?

The AUA (American Urology Associaion) recommends that Testosterone Replacement Therapy (TRT) be prescribed only to men who meet the clinical and laboratory definition of testosterone deficiency (Testosterone level of less than 300 ng/dL).
TRT can be given in five different ways:

Talk about the choices with your doctor.

What are the benefits of TRT?

Potential benefits of testosterone replacement therapy may include:

What are the side effects of TRT?

The side effects of TRT include:

Laboratory abnormalities that can occur with testosterone replacement include:

If you are taking hormone replacement therapy, regular follow-up appointments with your physician are important.

Prostate Cancer Risk and Testosterone Replacement

Guidelines suggest discussing the potential risk vs. benefit of evaluating prostate cancer risk and prostate monitoring. The doctor and patient will decide together regarding prostate cancer monitoring. For patients who choose monitoring, clinicians should assess prostate cancer risk before starting testosterone treatment, and 3 to 12 months after starting testosterone:

Who shouldn’t take testosterone replacement therapy?

Testosterone replacement therapy may cause the prostate to grow. If a man has early prostate cancer, there is concern that testosterone may stimulate the cancer’s growth. Therefore, men who have prostate cancer should not take testosterone replacement therapy. It is important for all men considering testosterone replacement therapy to undergo prostate screening before starting this therapy.
Other men who should not take testosterone replacement therapy include those who have:
