- DHT dihydrotestosterone
- steroidal antiandrogens eg, female hormones, estrogens
- steroidal antiandrogens eg, female hormones, estrogens
- non-steroid antiandrogens are also being developed. Although these compounds have no hormonal effects, they compete with natural androgens for receptors, so they can feminize a male fetus or male in the female body or initiate a feedback mechanism that overstimulates the testicles. Has undesirable effects.
- Type 1 enzymes are found in the sebaceous glands of the face and skin, and type 2 enzymes have been found to be distributed in the prostate.
