iamnaked said:How is this possible if DHT is produced from testosterone? This seems very unlikely unless castration suddenly triggers a vast increase in the production of 5-AR. You'd expect them to go down in equal levels, ceteris paribus.
Think about it: the fact that DHT falls off at a slower rate than testosterone implies that the amount of 5a-reductase is the limiting factor in DHT production, not the availability of testosterone. To put it another way, there's apparently more testosterone available than can be converted to DHT by the available 5a-reductase.
