The two protocols have not been prospectively compared in large studies. The only large available study presents the results of two large multicentric studies using the single- and multiple-dose Cetrorelix protocols (54). No differences are observed between the two regimens but as this is not a prospective randomized study; firm conclusions cannot be drawn from those data. A propspective randomized study compared the Ganirelix multiple dose protocol to the Cetroreliw single dose regimen and did not find a statistical difference in the PR between the two protocols (55,56).
