|Infertility||Procedure: Oestradiol pre-treatment and combination of GnRH agonist/antagonist protocol Procedure: GnRH agonist or antagonist protocol without oestradiol pre-treatment||Phase 2 Phase 3|
The combined ultrashort flare GnRH agonist /GnRH antagonist protocol during COH cycle resulted in a significantly higher clinical pregnancy rate in patients with poor embryo quality, with repeated IVF failures and in poor responders. This is a protocol combining the effect of the microdose flare on endogenous FSH release with the benefit of an immediate LH suppression of the GnRH antagonist.
A major disadvantage of the use of a GnRH antagonist protocol is the limitation for programming cycles, as the drugs administration is started on day 2 of the menstrual cycle and is strictly followed until the hCG criteria are met.
The purpose of the study is to perform oestradiol pre-treatment with the combined ultrashort flare GnRH agonist /GnRH antagonist protocol aiming to
- better programme an antagonist cycle and
- improve the IVF outcome parameters, from the production of more follicles / oocytes up to the rise in live birth rates.

Experimental: Oestradiol and ultrashort GnRH agonist/antagonist protocol
Women will begin pretreatment with 4 mg/day of 17 β-estradiol before the combination of GnRH ultashort agonist and antagonist protocol
Procedure: Oestradiol pre-treatment and combination of GnRH agonist/antagonist protocol
Active Comparator: GnRH agonist or antagonist protocol.
Women will undergo either a conventional short or long GnRH agonist or an antagonist protocol during COH for IVF
Procedure: GnRH agonist or antagonist protocol without oestradiol pre-treatment
