Protocol shift from agonist to antagonist or vice versa after an unsuccessful intracytoplasmic sperm injection cycle on the same patient does not improve outcome

While there's a growing data on the comparison of GnRH agonist and GnRH antagonist protocols, no clear study exists on the effects of both protocols on the same patient. The aim of the present study was to compare the success rates of protocol shift and proceeding with the same protocol after an unsuccessful intracytoplasmic sperm injection (ICSI) cycle.
