COH過程需考量2波FSH window

長療程可能優於短療程
pill+fixed GnRHantagonist可能優於flexible  GnRHantagonist

 we believe that stable and early suppression of endogenous gonadotrophins may be advantageous to achieve follicular synchronization and the highest clinical pregnancy rates. This may be achieved by either a long GnRH agonist protocol or a ‘long’ GnRH antagonist protocol (i.e. OC pretreated fixed GnRH antagonist protocol). In this respect, short or flexible regimens seem to be far from optimal.
