Among the effects of hypothyroidism is its potential effect on sexual desire and performance. There are around 7.3 million Americans afflicted with infertility according to the National Survey of Family Growth (Centers for Disease Control and Prevention, 2002).
Let's go back in time to the Society of Weight-Training Specialists 2005 Symposium held in Mississauga, Canada on November 4-5, 2005.
I called up 10 male friends above 40 years old and asked them if they ever had a Testosterone ( T) Level Test . Granted maybe they were in super healthy conditions and had no medical problems whatsoever , hence never needed to do a T –Test . Testosterone testing is used to diagnose several conditions in men, women, girls, and boys. The best time to take a Testosterone level test is between 7am and 10am when the T level is the highest. Alternatively, there is also a home DIY kit to have your own T level checked by checking your saliva. The blood spot sample is collected with a finger stick at home, then sent to the lab for analysis. I also had never heard of a testosterone test but that was interesting to read the various conditions that would require one. It is just a convenience for people who do not want or are unable to go test with a doctors. Testosterone replacement therapy is not without side effects, although most are manageable.
The first step in the proper monitoring of replacement therapy is providing your doctor with a thorough medical history.
I also strongly believe that if a patient goes to the doctor to obtain a Viagra, Cialis or Levitra prescription, the doctor should check the patient's testosterone blood levels to ensure that it is not the root of the problem. You should be evaluated after the first month of therapy to measure your testosterone blood levels. When using testosterone, your doctor will want to measure total blood testosterone levels right before the next corresponding injection after the first month (it takes a while for the blood levels to stabilize). Your doctor will check your hematocrit before starting testosterone, after 3 months and then every year after that. Be ready to have a digital rectal examination done and a prostatic specific antigen (PSA) blood test drawn prior to starting testosterone, and after 3 months. If you start experiencing breast tenderness, pain or growth, ask your doctor to measure your estradiol blood level using the sensitive assay (not the regular test used for women). Testosterone is the hormone responsible for normal growth and development and maintenance of male sex characteristics. Testosterone is produced by the testicles in males and by the ovaries in females, with small amounts also produced by the adrenal glands in both genders. As shown in Figure 1, the hormonal and reproductive function of the testicles (gonads) is regulated through interactions among the hypothalamus, the pituitary gland, and the gonads (commonly known as the hypothalamic-pituitary-gonadal axis [HPGA]). Primary hypogonadism is a hypergonadotropic condition (higher than normal levels of LH and FSH). As shown in Figure 2, testosterone in the body can convert into other hormones and metabolites.
In a healthy young male, about 60 percent of his testosterone is attached to sex hormone binding globulin (SHBG). Total testosterone is the sum of bioavailable testosterone and testosterone bound to SHBG. Proper monitoring by an experienced physician is extremely important to ensure optimal levels of testosterone, to maximize benefits and to minimize side effects.

As mentioned previously, hypogonadism is the medical term for the condition in males that is caused when the body is not producing sufficient amounts of testosterone. Common complaints for men with hypogonadism include: lower sexual desire (libido), erectile dysfunction (softer erections or lack of erections), depression, low energy and appetite, changes in body composition (lower lean body mass and higher abdominal fat), lower strength, reductions in body and facial hair, less mental focus and decreased height and osteoporosis (decrease in bone density). As Table 1 shows, normalizing testosterone in people who have lower than normal levels has dramatic benefits, among which are increased sexual desire, lean body mass, bone density, strength, mood, motivation, mental focus, and stamina. In addition to blood tests and physical examination, a brief screening instrument has also been developed by researchers at St.
Note that several of the above-mentioned problems can be caused by many other issues unrelated to low testosterone.
The benefit of this questionnaire is that it may encourage some men to seek medical advice. As discussed before, hypogonadism is caused when the testicles fail to produce normal levels of testosterone. Some commonly used medications such as Megace (an appetite stimulant), Nizoral (an anti-fungal agent), Prednisone (an anti-inflammatory corticosteroid) and Tagamet (an antacid) can also lower testosterone production. It is important that your doctor measure hormones in the HPGA cascade to diagnose what kind of hypogonadism you have.
The pituitary gland which controls testosterone production through the production of LH, is not secreting enough LH to stimulate production of testosterone by the testicles.


The testicles have lost their ability to produce testosterone, despite adequate amounts of LH. Since aging and illness can increase SHBG, which can attach to testosterone to impair its effectiveness, it becomes more important to test for free testosterone if you are older or being challenged by illness. Many doctors treat their patients according to hypogonadism symptoms regardless of what their testosterone blood levels are. Some physicians recommend doing hormone testing in the morning on an empty stomach, as many things can affect free testosterone measurements, including diet.
Some doctors tend to test this hormone in the late afternoon since the levels may be lower then. In theory testosterone replacement should approximate the body-s own nat-ural production of the hormone. There are testosterone replacement products that require daily dosing (orals, buccal, and gels), once a week or two weeks dosing (injections), and once every three- to four-month dosing (long-acting testosterone undecanoate injections (not yet approved in the United States as of 2010) or testosterone pellets).
Males who are hypogonadal can be given continuous testosterone replacement therapy in a wide assortment of ways. One man on hormone replacement therapy developed a potentially life-threatening blood condition called Polycythemia (high red blood cell count). I have heard of so many mistakes being made by people taking testosterone replacement therapy.

It is also called a serum testosterone test as it measures the total amount of the hormone in the serum , the amount of Free T in the serum and the bioavailable amount – which is the combination of free T and albumin-bound T. As you’ve pointed out though, there are definitely situations where having one would be of benefit.
Thats what I tell my male friends now and they are surprised cos they did not think that T level was important or can be tested. I've been taking testosterone replacement for 16 years and for the most part have had few side effects thanks to careful monitoring.
The three glands communicate through a cascade of hormones and a self-regulating feedback loop that controls the generation of each hormone.
This occurs when the testicles fail to produce sufficient levels of testosterone to suppress production of LH and FSH. It is characterized by disruption of central components of the HPGA resulting in decreased levels of GnRH, LH, or FSH. The most common cause of mixed hypogonadism is late-onset hypogonadism, which occurs with aging. It plays an important role in bone, hair, skin, and brain health as well as other functions in men. What most people don't realize is that in addition to sexual desire, testosterone also affects lean body mass, strength, bone density, mental focus, mood, fat loss, and other important factors in both males and females (Figure 4). However, these benefits can be erased if proper monitoring, dose adjustment, and appropriate choice of testosterone replacement option are not accomplished. It affected the way that I related to people and my ability to handle stress at work and in life. Then they can get their testosterone checked and have a physical examination to help determine whether they are indeed hypogonadal. The most common kind of hypogonadism presents low testosterone with normal or elevated FSH and LH levels, which indicates that your testicles are not responding to the signals of both LH and FSH. This could be caused by heavy alcohol intake or the effect of some medications on estrogen clearance in the liver.
This would be especially apparent if a male's total testosterone level is in the high reference range but his free testosterone (unbound) level is low. DHEA is a hormone produced by the adrenal glands that has a lot of the same benefits as testosterone.
Some studies report that free testosterone may be a better indicator for quality of life and lean body mass, but there are some conflicting studies on this issue. This decline is due to many factors that get in the way of retaining a healthy testosterone blood level.
Young and adult men tend to have higher testosterone levels in the morning than in the evening (see Figure 6).
Elevated insulin caused by eating carbohydrates, for instance, can increase free testosterone levels by reducing plasma levels of SHBG.
In my opinion, it is not practical to restrict testing of this hormone to early morning times and in a fasting state since intraday fluctuations are not that great in men over 30 and it may be equal to laboratory variability. The average male produces 4 to 7 mg of testosterone a day with plasma levels in early morning and lower levels in the evening. It is a decision that should not be made without a discussion with your health care provider. Some mistakes seriously impacted their quality of life, or resulted in men stopping testosterone prematurely. In any case if the results are not normal , it is advisable to do a proper blood serum test for T level. It's critical that you are monitored for side effects in addition to your testosterone level.


Patients who would like to be proactive can fill out this form and give a copy to their doctor.
Make sure your doctor is aware of your energy level, mood, and sexual function, as well as any potential side effects (tender breasts, urinary flow decrease, moodiness, and acne).
It is the primary androgenic (responsible for masculine characteristics) and anabolic (muscle building) hormone. Release of gonadotropin-releasing hormone (GnRH) from the hypothalamus regulates secretion of other hormones (gonadotropins) that influence the testicles by way of the pituitary. In this type of hypogonadism, low levels of LH do not allow for the proper stimulation of the production of testosterone by the testes. This is associated with osteoporosis, decreased lean body mass, reduced cognition, fatigue and impairment of libido and erectile function.
Large amounts of estrogen can cause mood swings, enlarged breasts (gynecomastia), fat gain, and water retention. As males grow older or if illness is present, SHBG sweeps up more and more testosterone, lowering free testosterone and its benefits. It is useful to also measure the level of free testosterone as this may be more indicative of how hormone therapy is progressing. This questionnaire is not a perfect predictor of low testosterone and should not replace tests for testosterone blood levels. In another, there is not enough secretion of LH and FSH needed to tell the testicles to produce needed testosterone. Among them are inflammatory states caused by being overweight, diet, medications, alcohol and street drug abuse, stress, lack of adequate sleep, and problems with how the body uses carbohydrates for energy (due to impaired function of the blood sugar controlling hormone insulin). Starting and stopping testosterone can have negative effects on someone's quality of life (more on this topic later).
It did in this man and the corresponding decreased need for hormone replacement therapy corrected the dangerous blood condition- Polycythemia. Testosterone tests are important to diagnose and cure certain syndromes and diseases associated with testosterone deficiency. However, you may soon discover that these tests are sometimes very technical and hard to understand. John Berardi, Charles Poliquin, Paul Chek, Dave Tate, Charles Staley, and Joe DeFranco just to name a few. Some men may experience one or more side effects that sometimes go unnoticed until it is too late. It is expected that every doctor have a similar form, although most do not ask questions pertinent to sexual function or on the use of androgens. Studies combining testosterone and oral sexual enhancement drugs have shown a synergistic effect on sexual benefits. It is important to be honest about when your doctor asks you about your sexual performance. Testosterone replacement needs to be stopped if increases in PSA above normal are observed.
GnRH controls the secretion of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) by the anterior pituitary.
The pituitary glands tried to increase testosterone at no avail even after increasing LH and FSH.
Levels of free testosterone can range between 0.3 and 5 percent of the total testosterone count, with about 2 percent considered an optimal level.
Some experts also think that our own bodies are slowly turning down their engines to get ready for a slower pace and eventual death.
These tests are done to evaluate ambiguous sex characteristics, precocious puberty, hirsutism and masculinization, virilizing syndromes in the female, infertility in the male, and rare tumors of the ovary and testicle. You may want to take a look at some sample baseline figures just to see how they may be used to interpret your condition. In part it is the underground, unmonitored use of testosterone that creates so much bad publicity for a very helpful product. Let your doctor know about all the medications you take so that medication-induced sexual dysfunction can be ruled out before starting testosterone. Note: at the start of testosterone replacement in older men, when testosterone blood levels are rapidly rising, PSA may also increase. Luteinizing hormone regulates the production and secretion of testosterone through the Leydig cells of the testes, while FSH stimulates the production of sperm.
It should be noted that high levels of cortisol (hypercortisolism), resulting from either the use of anti-inflammatory steroids or physical causes, could lead to hypogonadism. This is especially true when testosterone gels are employed, because they elevate DHT more relative to other options. Serrano has always been one of the more popular presenters at SWIS, and he is regarded quite highly by his peers when it comes to sports nutrition and supplementation.
