|Official Title:||The Flexible GnRH Antagonist Protocol Provides Better Results (IVF Outcomes) Than Flare up GnRH Agonist Protocol in Poor Responders|
- Ongoing pregnancy rate per embryo transfer
- Duration of ovarian stimulation, total rFSH used, estradiol, LH and progesterone concentration on hCG day.
- Number of mature oocytes retrieved.
- Number of fertilised oocytes.

Poor responders are women who fail to respond effectively to the usual gonadotropin stimulation protocol applied in an IVF cycle. It seems that a diminished ovarian reserve is the principal factor of poor ovarian response. Several strategies have been proposed for the management of poor responders, including flare up GnRH agonist regimens and the GnRH antagonist, which presents a new hope in this group of patients.
Comparisons: Poor responder patients (see inclusion criteria) commencing an IVF treatment cyle will receive ovarian stimulation treatment either using a GnRH antagonist (Ganirelix) or flare up agonist (Arvekap) protocol. Primary outcomes compared will be ongoing pregnancy rates in the two treatment groups.
