By virtue of its key role - preparing for an egg - oestrogen has come to stand for and embody a protective urge. It dominates the process by which we prepare for and protect that egg before its release into the world; it safeguards the hoped-for pregnancy yet only travels as far as the threshold of that potential being realised, stepping no further forward with it, like a mother stood waving at the door.
