From conception to death the steroid hormones regulate, con- 

 trol, arbitrate, and defend. With dexterity and imagination chemists 

 have synthesized compounds that perform and facihtate each of the 

 various effects of the hormones. With the array of activities and 

 compounds available we are predestined to full biochemical explana- 

 tion of these activities. Unknov^^n only are the rate and manner of 

 the eventual revelation, but therein is the key to the charm and 

 excitement of experimentation.
