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. 
Nature or nurture? Most perceived differences of behavior or preferences are determined by experiences and environment, not by biology. Babies are adaptable; they will develop according to whatever society they are born into. We have already come a long way toward equal job opportunities, but social constructions are not easy to dismantle. First, the message that Testosterone Rex is dead must reach the general public. Then we can concentrate on changing outdated social stereotypes. This will involve changing the environment our children grow up in. Toy stores have gender-coded aisles, men tell dumb blonde jokes, girls are clothed in pink dresses, some expert panels are composed entirely of men…. These may seem like minor things, but they add up. Fine says, “That’s why calling out even seemingly minor points of sexism matters.” There are actions those in power can take, such as implementing targets and quotas, auditing pay gaps, offering paternity leave, rooting out sexual harassment, and rethinking media portrayals. Science can’t determine public policy, but it can inform policymakers that men and women are not from different planets and their behavior and career choices are not dictated by their biology.
Dihydrotestosterone (DHT) (referred to as androstanolone or stanolone when used medically) can also be used in place of testosterone as an androgen. The availability of DHT is limited; it is not available in the United States or Canada, for instance, but it is available in certain European countries, including the United Kingdom , France , Spain , Belgium , Italy , and Luxembourg .  DHT is available in formulations including topical gel, buccal or sublingual tablets, and as esters in oil for intramuscular injection.  Relative to testosterone, and similarly to many synthetic AAS, DHT has the potential advantages of not being locally potentiated in so-called androgenic tissues that express 5α-reductase (as DHT is already 5α-reduced) and of not being aromatized into an estrogen (it is not a substrate for aromatase).
