What should my SHBG level be?

What are normal SHBG levels? 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.

What are the symptoms of high SHBG?

Therefore the symptoms of high SHBG levels are equivalent to those that arise due to low testosterone and oestrogen levels.

  • Decreased sex drive.
  • Depression and anxiety.
  • Reduced muscle and bone mass.
  • Vaginal dryness.

Can high SHBG cause hair loss?

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.

What causes SHBG to rise?

Excess iron levels in the liver (iron overload) can also cause high SHBG [53]. SHBG is mainly produced in the liver, and liver damage can affect SHBG production. Liver cirrhosis, hepatitis, and iron overload have each been linked with increased SHBG.

Does stress raise SHBG?

Men and women undergoing a stress test had elevated levels of SHBG (and testosterone, estradiol, androstenedione, adrenocorticotropic hormone (ACTH), and cortisol levels, as well as increased heart rate, systolic blood pressure, and diastolic blood pressure) in a study on 39 people [66].

What drugs increase SHBG?

In the human hepatoma cell line (HepG2), thyroid and estrogenic hormones, and a variety of drugs including the antioestrogen tamoxifen, the phytoestrogen, genistein and mitotane (Op’DDD) increase SHBG production and SHBG gene promoter activity.

Does vitamin D increase SHBG?

In principle, higher levels of vitamin D may strengthen the protective association of higher SHBG, either through independent pathophysiological mechanisms25–27 or as a factor that could increase androgen synthesis in men.

What is a sex hormone binding globulin test?

This test measures the level of sex hormone binding globulin (SHBG) in your blood. SHBG is a protein made by your liver. It binds tightly to 3 sex hormones found in both men and women. These hormones are estrogen, dihydrotestosterone (DHT), and testosterone. SHBG carries these 3 hormones throughout your blood.

Does hormone replacement therapy increase SHBG levels?

In two studies on almost 500 women, hormone replacement therapy increased SHBG levels [ 29, 30 ]. Studies in cells found increased SHBG production at high concentrations of the following female sex hormones: High estrogen is associated with high SHBG.

What hormones does SHBG bind to?

It binds tightly to 3 sex hormones found in both men and women. These hormones are estrogen, dihydrotestosterone (DHT), and testosterone. SHBG carries these 3 hormones throughout your blood. Although SHBG binds 3 hormones, the hormone that’s critical in this test is testosterone.

What increases SHBG and DHT levels?

Research has found that the following may increase SHBG levels: In a randomized clinical trial of sedentary men aged 40 to 75, a year-long program of moderate aerobic exercise increased SHBG and DHT. The exercise program had no effect on other androgens in this group.
