Concentration androgen binding protein. Medical search. Frequent questions

Most of the circulating testosterone is bound to carrier proteins (sex hormone-binding globulin [SHBG], and albumin). (cdc.gov)
Sex hormone-binding globulin (SHBG) is the blood transport protein for androgens and estrogens. (cdc.gov)
SHBG has a high binding affinity to dihydrotestosterone (DHT), medium affinity to testosterone and estradiol, and only a low affinity to estrone, dehydroepiandrosterone (DHEA), androstendione, and estriol. (cdc.gov)
Albumin, which exists in far higher concentrations than SHBG, also binds sexual steroids - although with a clearly lower binding affinity (e.g. about 100 times lower for testosterone). (cdc.gov)
2001). SHBG serum concentrations depend on the extent, duration, and the kind of estrogen applied, and how regulation takes place. (cdc.gov)
In the serum SHBG mainly takes over the transportation of steroids and the reduction/regulation of the effect of androgen. (cdc.gov)
2002). Decreased SHBG serum levels are associated with conditions where elevated androgen levels are present or where the effect of androgen on its target organs is excessive. (cdc.gov)
Measurement of SHBG can be an important indicator of an excessive/chronic androgenic action where androgen levels are normal, but where clinical symptoms would seem to indicate androgen in excess. (cdc.gov)
SHBG is a useful supplementary parameter in the determination of androgen where a relatively high concentration of free androgen (e.g. testosterone) is suspected (Pugeat, et al. (cdc.gov)
Pregnant women have markedly higher SHBG serum concentrations due to their increased estrogen production. (cdc.gov)
Decreased SHBG concentrations are often seen with hypothyroidism, polycystic ovarian syndrome (PCOS), obesity, hirsutism, elevated androgen levels, alopecia, acromegaly and some polymorphisms on the SHBG gene. (cdc.gov)
