What is the Difference Between Total and Free Testosterone?
When something doesn't seem to be operating well, most men have a strong desire to discover the source of the problem so that it may be "fixed." Men who are having problems in the bedroom may spend time on the internet looking for solutions. And sooner or later, those inquiries will turn to testosterone levels in men. If you look a bit deeper, you'll come across the term "free testosterone." Isn't it supposed to be easy to figure out from here?
Well, not quite. Some things are unquestionably simpler to comprehend than others. And testosterone levels in males fall under the group of more difficult to comprehend topics. In fact, it can be really perplexing. So, here's a breakdown of the differences between total and free testosterone, as well as what the figures represent and why it matters.
Does woman produce testosterone?
Most people associate testosterone with sexual function and muscular growth, but this hormone has an impact on the entire body in both men and women.
Testosterone is created in the testes, ovaries, and adrenal glands, as well as through precursor hormones (hormones that the body transforms to testosterone). We'll concentrate on how testosterone, also known as "the male hormone," affects men in article.
What is the life cycle of testosterone?
As boys reach puberty and enter adolescence, testosterone levels rise, transforming their bodies to virile and vigorous young men. Energy levels are at an all-time high, and robust libidos are frequently on exhibit. Of course, all of this occurs just in time for a person to develop a sexual interest, which frequently leads to relationships and the birth of children.
Then, as males become older, testosterone levels drop. Today, despite the ongoing dispute about why, we are witnessing declines in certain men at far younger ages than would have been expected only a few decades ago. Although ageing isn't necessarily the source of the decline, something is certainly happening. Men's testosterone levels are dropping, and this, combined with their experiences with erectile dysfunction, is leading to an increase in the number of young men seeking medical guidance and therapy. Men's testosterone levels can be used to diagnose a range of problems, including sexual dysfunction.
What's the difference between free and total testosterone?
Sex-hormone binding globulin (SHBG) or albumin binds around 98 percent of the testosterone produced by the body. "Bound testosterone" is the term for this situation. The remaining 2% is referred to as "free testosterone."
This unbound or "free" testosterone binds to testosterone receptors in the cells of the body. Free testosterone enables a cell's functions, such as cell reproduction in the bones and muscles, by allowing it to absorb it. In men, free testosterone is also responsible for the development of secondary sexual traits. Face hair and a deeper voice are examples of this.
Total testosterone is the sum of all hormones present in the bloodstream, as the name implies. While some testosterone tests solely measure total testosterone, they may not be as useful as previously believed. This is why.
For total testosterone, a 98 percent proportion is considered typical, but aberrations might arise. Testing only for total testosterone levels ignores the possibility of high SHBG or albumin bonding. Here's why it's important. it is conceivable to have normal total testosterone levels but inadequate free testosterone to fulfil vital duties. little decrease in free testosterone can cause poor muscle development, irritation, decreased libido drive, and a variety of other disorders that aren't immediately associated with it.
As a result, while total testosterone levels may appear to be normal, low free testosterone levels may lead to incorrect diagnosis and treatment. A patient, for example, may not require any additional testosterone. They may just require less supplement that prevent testosterone to other hormones like oestrogen. This is why testing for free testosterone levels, rather than just total testosterone, may be critical.
Testosterone that is bioavailable.
Until recently, the only form of testosterone considered biologically active was free testosterone. The part of the hormone linked to serum albumin, on the other hand, appears to become accessible in the capillary bed. As a result, testosterone that isn't coupled to SHBG is likewise considered "bioavailable."
Bioavailable testosterone can be thought of as a reserve resource, ready to be used when the body's free testosterone levels are low. Scientists are still unsure how much bioavailable testosterone is taken by cells in these circumstances.
Bioavailable and free testosterone levels are usually equal. Certain medical conditions and drugs have been found to cause exceptions to this rule. Corticosteroids and sex steroids, for example, can produce an increase or decrease in SHBG levels. Medical practitioners may have trouble correctly detecting problems in such situations. As a result, it's vital that men tell their doctors about all of the prescriptions they're taking during their visit.
There are a variety of different disorders that can lead to diagnostic difficulties. These are some of them:
SHBG-binding anomalies caused by genetics
Hepatitis is a disease of the liver.
Systemic disease is a serious condition that affects the entire body.
Increasing Free Testosterone Levels.
Erectile Dysfunction and Hormonal Imbalances.
Testosterone is undeniably important in a man's sexual function. Erectile dysfunction (ED) and diminished libido can be caused by testosterone imbalances. However, testosterone may be just one of several factors that contribute to ED.
