Testosterone/SHBG Ratio

What's

The Testosterone/SHBG Ratio is a measure that helps us understand how much of the hormone testosterone is available for your body to use. Testosterone, often associated with men but also important for women, is a hormone that plays a key role in many functions, such as muscle strength, bone density, and sex drive. SHBG, or Sex Hormone Binding Globulin, is a protein that binds to testosterone. When testosterone is bound to SHBG, it's not available for your body to use. So, the Testosterone/SHBG Ratio essentially tells us how much 'free' or usable testosterone you have in your body. It's like a snapshot of your body's testosterone availability, helping to provide a more complete picture of your hormonal health.

If Your Levels Are High

A high Testosterone/SHBG ratio means that there's a larger amount of 'free' or usable testosterone in your body. This could be due to a variety of reasons. For instance, you might be producing more testosterone than usual, which can happen in conditions like polycystic ovary syndrome (PCOS) in women or testicular tumors in men. Alternatively, your body might be producing less SHBG, which means more testosterone is left unbound and available for use. Certain medications, like steroids or thyroid hormones, can also decrease SHBG levels. Lastly, lifestyle factors like obesity or high insulin levels can also lead to a high Testosterone/SHBG ratio, as they can both increase testosterone production and decrease SHBG levels.

Symptoms of High Levels

Symptoms of a high Testosterone/SHBG ratio could include increased muscle mass, excessive hair growth, acne, irregular menstrual cycles in women, and an enlarged prostate in men.

If Your Levels are Low

A low Testosterone/SHBG ratio means that there's not much 'free' or usable testosterone in your body. This could be due to a variety of reasons. For instance, you might have low testosterone production, which can be caused by conditions like hypogonadism or certain genetic disorders. Alternatively, your body might be producing too much SHBG, which binds to testosterone and makes it unavailable for use. This can happen due to factors like liver disease or hyperthyroidism. Certain medications, such as anticonvulsants or hormone therapies, can also increase SHBG levels. So, a low Testosterone/SHBG Ratio could indicate an imbalance in your hormonal health due to these or other factors.

Symptoms of Low Levels

Symptoms of a low Testosterone/SHBG ratio could include fatigue, decreased sex drive, muscle weakness, and loss of bone density. In men, it may also lead to erectile dysfunction, while in women, it could result in irregular menstrual cycles.

The Male Blood Profile I provides a baseline assessment of sex and adrenal hormones in blood. It includes a PSA test to evaluate prostate health.

Male Blood Profile II by ZRT Laboratory

Blood Spot

The Male Blood Profile II provides a baseline assessment of sex, adrenal, and thyroid hormones in blood. This profile combines the Male Blood Profile I with the Essential Thyroid Profile.

Serum

The Male Serum Hormones Advanced Profile provides a baseline assessment of sex, adrenal, and thyroid hormones. It is the serum equivalent of the Male Blood Profile II.

Serum

The Male Serum Hormones Basic Profile provides a baseline assessment of sex hormones, adrenal hormones, and TSH. It is the serum equivalent of the Male Blood Profile I.
