Know Your Testosterone Level

xpert — Fri, 03 Sep 2010 17:52:53 +0000

Do you know what your testosterone level is? You ought to. Your testosterone degree does a lot more than determine your sex drive. It’s a major factor in determining the high quality of your life.

Testosterone has many functions. It is responsible for several of the attributes males have. It increases muscle mass and tone, makes the voice deeper and matures the reproductive system when puberty hits, helps hair grow on the body and face, and gives a person their libido, or sex drive. It also gives an individual a general feeling of well being. It makes people feel great.

Your testosterone level determines the extent of these effects. Someone having a high testosterone level is a lot more likely to have more muscle, more body hair, and have a deeper voice. Somebody with a lower testosterone level is most likely to be the opposite having a greater voice, much less body hair, and much less muscle mass.

Both men and ladies produce testosterone. However, testosterone is an androgen, or a male hormone, so males have a lot higher levels than ladies. That’s why males have male attributes while ladies don’t. Ladies have about 1/7 the quantity of testosterone that men do, so women will not develop large muscles, have a deep voice, etc.

Testosterone is created primarily in the gonads. The testes produce it in males while the ovaries create it in ladies. The adrenal glands also produce small amounts. Luteinizing hormone, LH, starts the production of testosterone. LH is created in the pituitary gland and stimulates the testes to produce testosterone.

testosterone therapy

Testosterone is the most important representative of the male sex hormones collectively called androgens. Using cholesterol as a base, the male gonads (testes) produce between 4 and 10 mg of testosterone per day. Testosterone is responsible for the development of secondary male sex characteristics also called the androgenic functions of testosterone. Some examples of these characteristics of this Testosterone is increased growth of body hair, beard growth, deep voice, increased production of sebaceous glands, development of the penis, aggressiveness, sexual behavior, libido, and the maturation of sperm.

Promotion of the protein biosynthesis that are responsible for the highly anabolic characteristics of testosterone is another important function of Testosterone. This Testosterone accelerates muscle buildup, increases the formation of red blood cells, speeds up regeneration, and speeds up recovery time after injuries or illness. This Testosterone also stimulates the entire metabolism which results in the burning of bodyfat.

Inhibition of the gonad regulating cycle, including the hypothalamohypophysial testicular axis, which regulates the amount of testosterone produced in the organism. If the testosterone level in the blood is high, the testes will signal the hypothalymus to release less LHRH (leutenizing hormone releasing hormone). Thus the hypophysis releases less gonadotropin LH Testosterone (leutenizing hormone) and FSH Testosterone (folic stimulating hormone). Consequently, the Leydig’s cells in the testes reduces the production of testosterone. In other words, if you have to much testosterone, your body will tell itself to reduce or even stop production of Testosterone until it is back down to its normal levels.

During puberty, testosterone levels are at their lifetime peak. Testosterone begins to decline around the age of 23. This is where testosterone therapy comes into play. Many men suffer from the lack of important hormones and Testosterone replacement therapy is simply the most effective way to combat the signs of aging. Sex Testosterone hormones like “Estrogen and progesterone profoundly affect the brain. The increasing memory loss and mild mental confusion emerging in middle age are largely due to declining levels of estrogen and progesterone in women. In men, these same problems are caused by decreasing testosterone and increasing estrogen levels beginning in the late thirties or early forties.

Normal testosterone levels

Prostate Cancer Drug Reduces Testosterone Levels In As Little As Three Days Without Initial Hormone Surge

ScienceDaily (Dec. 3, 2008) — More than 95 per cent of men who took degarelix for prostate cancer saw their testosterone levels fall dramatically as early as three days after they started treatment, according to a paper in the December issue of BJU International.

The article went on to say:
The hormonal side-effects experienced by the three treatment groups were similar to previously reported effects for androgen deprivation hormone therapy.

I don’t like the sound of this. Has there been a study to see if lowering testosterone ihis way increases the risk of heart disease? Testosterone has been shown to prevent heart disease and reduce depression. Is that what they refer to about androgen deprivation therapy side effects?

Normal Testosterone Levels From 300 to 1000

xpert — Tue, 25 Nov 2008 22:16:24 +0000

Normal testosterone levels

Normal testosterone levels range from 300 to 1,000. Your level of 246 is just below normal. However, if your normal level were 800 to 1000, even a drop to 400 to 500 (which is still within normal limits) could cause symptoms, so a drop to below normal could almost certainly lead to problems. If, on the other hand, your normal were 300 to 400, a drop to 246 would most likely not be very noticeable.

As men age, testosterone levels generally decrease. Perhaps this is what is happening to you, and your body may simply need time to adjust. However, with treatment, the testosterone level should have risen; yours has not. Return to your doctor to discuss the next step, since current treatment clearly is not working.

Your doctor may choose to switch you to an injectable testosterone or refer you to a urologist or endocrinologist for further testing to find out why your levels have dropped below normal. The specialist will probably order more sensitive tests to check your testosterone level, as well as check for pituitary or testicular abnormalities.

Testosterone News 11/20/2008 | A crash in testosterone leaves you tired, depressed, low libido

xpert — Thu, 20 Nov 2008 19:49:39 +0000

Screening plan to tackle male menopause

Boost weight loss, libidi, Muscle.

Doctors have drawn up plans to screen older men for the male menopause, amid concerns that as many as one in five of the over-65s may be affected.

The existence of a male equivalent to the menopause is still controversial, but most experts agree some men experience a crash in testosterone that can leave them tired, depressed and lacking in libido.

The so-called “andropause” has also been linked to diabetes and obesity, and in some cases can be treated with testosterone injections.

Medical associations, including the European Association of Urology, have issued guidelines recommending that men with type 2 diabetes and symptoms of testosterone deficiency be tested.

“It is going to pick up a lot of men with low testosterone who previously would have been sat at home without their doctor investigating it,” said Hugh Jones, professor of andrology at Sheffield University.

Unlike the menopause in women, not all men experience the andropause and scientists say that only those showing clear symptoms should be offered testosterone injections. read more

testosterone boosts sexual episodes among postmenopausal women with low libidos

A study published in the July 2008 issue of Archives of Internal Medicine
found a high percentage of women in the United States experience low sexual desire and another study showed a high dose of testosterone boosts sexual episodes among postmenopausal women with low libidos.

The first study showed prevalence of low sexual drive ranged from 26.7 percent among premenopausal women to 52.4 percent among naturally menopausal women. Of surgically menopausal women, 12.5 percent had hypoactive sexual desire disorder.

Low sexual drive is associated with low levels of arousal and sexual excitement, resulting in infrequent orgasms and reduced sexual satisfaction.

For the study, Suzanne L and colleagues from the University of North Carolina in Chapel Hill and Procter & Gamble Pharmaceuticals in Mason, Ohio surveyed 2,207 U.S. women aged 30 to 70 and in stable relationships that lasted equal or greater than three months for their sexual desire.

The researchers focused on 755 premenopausal women and 552 naturally and 637 surgically menopausal women. Low sexual desire was defined using the profile of female sexual function desire domain and HSDD was defined using the profile of female sexual function and the personal distress scale.

Suzanne and colleagues concluded that “Prevalence of low sexual desire is elevated among surgically and naturally menopausal women vs premenopausal women. Distress about low desire (HSDD) appears to be more than twice as prevalent among surgically menopausal women vs premenopausal women, although the estimate is fairly imprecise.”

One treatment for low sexual desire in women is use of testosterone. Another study published in a recent issue of the New England Journal of Medicine found that 300 micrograms of this hormone per day for 24 weeks more than doubled sexual episodes or the frequency of having sex among postmenopausal women with hypoactive sexual desire disorder, a condition that is caused by a low libido and affects as many as 32% of the menopausal population .

Editor comment: Remember that this is Synthetic Testosterone they are talking about here. Natural testosterone as made by the body has no negative symptoms.
But the testosterone patches for women comes with a risk. Of 534 women receiving the treatment, 4 were diagnosed with breast cancer
during the one-year study compared to one of 277 women in the control group.

Estrogen, Testosterone May Affect Atherosclerosis

Doctors may eventually check sex hormones to assess heart disease risk

By David March
Johns Hopkins Medicine

Naturally produced sex hormones may influence the risk and progression of atherosclerosis, or hardening of the arteries, Johns Hopkins researchers report in a recent study. The findings may help explain the increased risk men have of developing heart disease, which runs about twofold higher than women’s heart disease risk worldwide.

The study suggests that older women who produce a relatively high amount of estrogen are more likely to develop coronary artery calcium, or CAC, a component of the fatty plaque that builds up in blood vessels and hardens arteries. Older men with relatively high amounts of testosterone are also more likely to develop CAC. However, once CAC is present, higher testosterone appears to help prevent CAC from progressing too quickly in men’s arteries. These findings were presented Nov. 11 at the American Heart Association’s annual Scientific Sessions in New Orleans.

“We know many things that increase the risk of cardiovascular disease, such as high cholesterol and diabetes,” said Erin D. Michos, assistant professor of medicine at the Johns Hopkins University School of Medicine and its Heart and Vascular Institute, in an interview. “But 10 percent to 20 percent of people who get heart disease don’t have these risk factors, so we need to understand other factors that might be involved. Our results suggest that someday, in addition to testing your cholesterol and blood sugar levels to assess your heart disease risk, your doctor may want to measure your sex hormone levels.”

The study assessed whether sex hormones affect the risk of atherosclerosis using data from the Multi-Ethnic Study of Atherosclerosis, or MESA, an ongoing study that’s been tracking 6,814 patients of four different races since 2000 to determine factors that influence risk of developing cardiovascular disease. The MESA study recruited healthy people from six communities across the United States. Through a baseline assessment and regular checkups, researchers track each volunteer to learn what factors affect a person’s risk of developing cardiovascular disease or progressing once the disease develops.

For the Johns Hopkins study, researchers used data from 2,700 male and 1,646 postmenopausal female MESA participants who did not use hormone replacement therapy. At the beginning of the study, participants answered detailed questionnaires about their demographics and medical history, and they received a basic health assessment measuring their height, weight and blood pressure. Participants also received a CT scan measuring their baseline level of CAC and had their blood drawn to measure blood concentrations of various sex hormones, including estradiol, the dominant type of estrogen in women, and testosterone, the dominant sex hormone in men. About half the participants had a second CT scan 18 months later. The other half had their second scan 37 months after the initial scan.

Taking into account factors known to affect atherosclerosis risk, such as age, body mass index, blood pressure, and exercise and smoking habits, Michos and her colleagues assessed whether there was a correlation between changes in CAC between patients’ two scans and their levels of sex hormones. In women who had no baseline CAC, the researchers found that women with higher amounts of estrogen were 30 percent more likely to develop CAC by their second scan than women with lower levels of estrogen. This risk was most pronounced in women older than 65. Levels of estrogen did not seem to significantly affect whether CAC increased in women who already had CAC at baseline.

In those men who had no CAC at baseline, the researchers found that men with higher testosterone levels were 48 percent more likely to develop CAC than those with the lowest testosterone levels, with the risk greatest among men older than 55. In men who already had CAC at baseline, higher testosterone levels appeared to have a protective effect, reducing the chances that CAC measurements would increase at follow-up.

Michos added that the role that sex hormones play in cardiovascular disease is complex, with often diverse and contradictory effects. While the Johns Hopkins study looked at early atherosclerosis in the coronary arteries, sex hormones may also affect heart disease risk through other mechanisms, including influencing inflammation, blood clotting and whether blood vessels are constricted or relaxed. In the future, she and her colleagues plan to study how sex hormone levels might affect the risk of specific cardiovascular incidents, such as heart attacks and strokes, in men and women.

MESA is funded by the National Heart, Lung and Blood Institute, a member of the National Institutes of Health.

Other researchers who participated in this study are Dhananjay Vaidya, Sherita Hill Golden and Pamela Ouyang, all of Johns Hopkins; Susan R. Heckbert, of the University of Washington; and Mary Cushman, of the University of Vermont.
