Emerald Star - no worries. Down regulation in effect goes for a cycle and a half. We begin by using a nasal spray, synarel, at the end of this cycle to surpress the amount of estrogen produced by the ovaries. It allows us to move forward with a more contolled stimulation in the following cylce. If you want more detials its probably easier to google down regulation - you will probably find a brief explanation on one of the IVF clinic websites. I will google yous too and have a look at the difference.
