Brief summary

The aim of this randomized controlled study is to compare the efficacy of a modified dual trigger protocol \[a single bolos of HCG combined with two successive doses of a GnRH agonist \] with HCG \[a single bolos administered 36 hours before oocyte retrieval \] in triggering ovulation in normo-responders undergoing ovarian stimulation using the antagonist protocol.

Interventions

DRUGModified dual trigger

HCG (10000 IU /IM) and triptorelin (0.2 mg/S.C) are administered 36 hours before ovum pickup . Moreover, 0.1mg of triptorelin is administered 24 h prior to ovum pick-up.

DRUGHCG

HCG (10000 IU/IM ) is administered 36 hours before ovum pickup.
