Currently, the SHBG test is not performed frequently or routinely. In many cases, health practitioners feel that the total testosterone , and perhaps free testosterone (as measured by a method called equilibrium dialysis), provides sufficient information. SHBG is ordered primarily when the total testosterone results do not seem to be consistent with clinical signs and symptoms , such as infertility, decreased sex drive, and erectile dysfunction in men or infertility , irregular menstrual periods, and excess facial and body hair in women.
There are also many synthetic sex steroids. Synthetic androgens are often referred to as anabolic steroids . Synthetic estrogens and progestins are used in methods of hormonal contraception . Ethinylestradiol is a semi-synthetic estrogen. Specific compounds that have partial agonist activity for steroid receptors , and therefore act in part like natural steroid hormones, are in use in medical conditions that require treatment with steroid in one cell type, but where systemic effects of the particular steroid in the entire organism are only desirable within certain limits.
