Jessica asked the Naked Scientists:
   Women take large doses of Oestrogen every day. What is the effect of oestrogen contraceptive pills on the ovaries?

Helen Simpson spoke about males taking anabolic steroids:
If you take anabolic steroids, they mimic testosterone. The pituitary and hypothalamus stop sending signals to the testes, as they don't need to produce testosterone.  Pituitary & hypothalamus go to sleep, the testes shrink, and if you take them for enough years, the glands go to sleep permanently.

From my research, we only have something like 1.8 µg of oestrogen in our bodies, yet women are taking 30 µg of oestrogen daily.
What do you think?
