Testosterone [Figure 1] is the main male sex hormone. It is responsible for male sexuality and is the main hormone-producing the features associated with masculinity such as substantial muscle mass, facial hair, libido, and sperm production. Besides, the hormone has other vital functions as the basic chemical composition of testosterone is steroidal; and steroids are known to have significant physiological, as well as psychological, effects in male individuals, especially adults. Testosterone production is reduced gradually in men starting from the age of 30. Hence, testosterone blood concentrations slowly diminish as age progresses. As a result, men may experience a number of physiological and psychological events, such as a lack of sex-drive, erectile dysfunction, acute depression, fatigue, low energy levels, and insomnia.
Another recent development is the production of adhesive tablets which are applied twice daily to the buccal mucosa on the gum above the incisor teeth. The tablets gradually release testosterone into the systemic venous circulation and steady state physiological concentrations are achieved in most patients within two days (Ross et al 2004). Some patients do not like the feeling of the tablet in the mouth or find that there is an abnormal taste in the mouth, but local adverse effects are usually mild and transient (Wang, Swerdloff et al 2004).
46 year old whose suffered with low libido and all the related symptoms for over a decade. Finally had the courage to have a frank talk with dr. and urologist. Testosterone level 165, free testos level 3.6. Re-doing blood work again just to be sure in the next week or so, and will post updates then as things progress. Normal ranges are 300-1200 and 6 to 12.
As mentioned earlier, too much protein can negate testosterone production quite a bit. If your protein intake is over 0.85g/lb of body weight a day, then you may not be making full use of each of the nutrients. Consuming these high amounts of protein can cause your cortisol and SHBG levels to increase, which in turn lowers testosterone production. What do you get out of this deal? Increased fat gain and lower testosterone levels.
Currently available testosterone preparations in common use include intramuscular injections, subcutaneous pellets, buccal tablets, transdermal gels and patches (see Table 2). Oral testosterone is not widely used. Unmodified testosterone taken orally is largely subject to first-pass metabolism by the liver. Oral doses 100 fold greater than physiological testosterone production can be given to achieve adequate serum levels. Methyl testosterone esters have been associated with hepatotoxicity. There has been some use of testosterone undecanoate, which is an esterified derivative of testosterone that is absorbed via the lymphatic system and bypasses the liver. Unfortunately, it produces unpredictable testosterone levels and increases testosterone levels for only a short period after each oral dose (Schurmeyer et al 1983).
Lose some weight – It goes without saying that being overweight is unhealthy for more than one reason. As your weight increases, your testosterone levels decrease inevitably. The good news is that as soon as you start losing weight, you can reverse this process and your testosterone levels will begin rising again. Could you think of a better reason to exercise regularly?
I’m a 70 year old male. Here’s my brief story, I was exhausted all the time after an encounter with H-Py-Lori. After may tests it was found out that my T-count was at about 250. I was put on a testosterone cream replacement therapy. Before I knew it, at about month I was at 1500 count. This was at 4 cream applications a day. The doctor took me down to twice/two applications a day, now I was at 600. I felt great at both levels.
For men with low blood testosterone levels, the benefits of hormone replacement therapy usually outweigh potential risks. However, for most other men it's a shared decision with your doctor. It offers men who feel lousy a chance to feel better, but that quick fix could distract attention from unknown long-term hazards. "I can't tell you for certain that this raises your personal risk of heart problems and prostate cancer, or that it doesn't," Dr. Pallais says.
The biologically available part of total testosterone is called free testosterone, and it’s readily available to the cells. Almost every lab has a blood test to measure free testosterone. Even though it’s only a small fraction of the total, the free testosterone level is a pretty good indicator of low testosterone. It’s not perfect, but the correlation is greater than with total testosterone.
As with a number of treatments or medicines that have been around for a long, long time, it hasn’t been scrutinized like a new drug would be. And although they’ve been discussed, there aren’t any large-scale, randomized controlled clinical trials of testosterone-replacement therapy under way. [See “A male equivalent to the Women’s Health Initiative?” below.]
When I first started TRT, my physician prescribed a cream that you rub into your skin. The cream version of TRT is not too convenient, because if someone touches you while you have the cream on, the testosterone can rub off on him/her. This can be really bad around kids or pregnant women. If you’re sleeping next to someone, the cream can get on the sheets and transfer over that way, too. The cream can be annoying, but it works. There’s also a gel version called AndroGel; I skipped it because it doesn’t absorb as well as the cream does.
Testosterone was first used as a clinical drug as early as 1937, but with little understanding of its mechanisms. The hormone is now widely prescribed to men whose bodies naturally produce low levels. But the levels at which testosterone deficiency become medically relevant still aren’t well understood. Normal testosterone production varies widely in men, so it’s difficult to know what levels have medical significance. The hormone’s mechanisms of action are also unclear.
Before we go any further, know that fenugreek is an herb of Asian origin, commonly used in Indian cuisine. The Indians have been consuming it as an aphrodisiac and an herbal cure-all for centuries which might explain why that waiter in your local Indian restaurant is always smiling. As it turns out, there is actually some validity to the purported claims.
Studies also show a consistent negative correlation of testosterone with blood pressure (Barrett-Connor and Khaw 1988; Khaw and Barrett-Connor 1988; Svartberg, von Muhlen, Schirmer et al 2004). Data specific to the ageing male population suggests that this relationship is particularly powerful for systolic hypertension (Fogari et al 2005). Interventional trials have not found a significant effect of testosterone replacement on blood pressure (Kapoor et al 2006).
“Our hypothesis was that testosterone would be good for the coronary arteries because we thought that by repleting testosterone to healthy levels there would be an improvement in the cholesterol panel and atherosclerosis burden. But what we found was the opposite, that atherosclerosis actually progresses faster under the influence of testosterone.”
