In my studies of hormones one thing becomes very apparent.
Whether good or bad, these things tend to perpetuate themselves.
In fact, this extends to all areas of health, beyond hormones.
All hormones work in the body via feedback loops.
Ideally, what this means is that if something is too low, say testosterone for example, the body takes that feedback, and then will trigger the creation of more.
If it is too high then production will be stopped, or it will be converted or removed, in order to bring it down to normal.
