What is SHBG normal range?

The normal ranges for SHBG concentrations in adults are: Males: 10 to 57 nanomoles per liter (nmol/L) Females (nonpregnant): 18 to 144 nmol/L.

How do you read SHBG?

In simple terms, the higher your SHBG, the fewer sex hormones are available to the body, while the lower your SHBG, the more sex hormones are available to the body. SHBG favours testosterone over oestradiol, meaning that it is also important for controlling the balance between these two hormones.

What is a SHBG level?

What is it used for? An SHBG test is most often used to find out how much testosterone is going to the body’s tissues. Testosterone levels can be measured in a separate test called total testosterone. This test shows how much testosterone is in the body, but not how much is being used by the body.

What is the conversion of testosterone?

Testosterone is converted in the body to two active metabolites, 17β-estradiol (E2) and 5α-dihydrotestosterone (DHT), which mediate some actions of testosterone in target tissues.

Do you want high or low SHBG?

Excessively high SHBG is problematic especially for males and athletes because it decreases the amount of free testosterone. High levels of SHBG are associated with infertility, a decreased sex drive, and erectile dysfunction, especially when total testosterone levels are already low [4].

Does high SHBG cause low testosterone?

SHBG controls the amount of testosterone that your body tissues can use. Too little testosterone in men and too much testosterone in women can cause problems. The level of SHBG in your blood changes because of factors such as sex and age. It can also change because of obesity, liver disease, and hyperthyroidism.

Why is my SHBG so high?

Some evidence suggests that continuous use of oral contraceptives can also increase your SHBG levels. Finally, undernourishment, as seen in anorexia nervosa, and estrogen or thyroid hormone treatment can cause higher than normal SHBG levels in women.

Is low SHBG good?

Low SHBG is also associated with elevated levels of triglycerides and low-density lipoprotein (LDL) [2]. Because of this, low levels of SHBG are linked with multiple cardiovascular illnesses in both sexes, including heart disease, type 2 diabetes, and high blood pressure [3].

How do you convert nmol l to NG dL?

While the US generally use nanograms/decilitre and picograms/millilitre, other countries, including New Zealand, use nanomoles/litre and picomoles/litre. The conversion factors are: 1 nmol/litre = 28.85 ng/dL.

What is a good testosterone level nmol l?

Normal Results Male: 300 to 1,000 nanograms per deciliter (ng/dL) or 10 to 35 nanomoles per liter (nmol/L) Female: 15 to 70 ng/dL or 0.5 to 2.4 nmol/L.

Does vitamin D reduce SHBG?

Conclusions: Lower 25(OH)D concentrations were associated with lower SHBG levels and higher free testosterone levels in both men and women, and lower estradiol and higher DHEA levels in women, independent of adiposity and lifestyle.

Can high SHBG cause hair loss?

SHBG and hair SHBG not only controls the transportation and balance of hormones, but it also influences your hair. If the SHBG level is not optimal, it may lead to hair loss. Yes, if you do not have optimal SHBG levels you can notice some changes to your hair, and you can experience hair loss as well.
