Recently, several new promising modifications have been introduced to clinical practice that may simplify and optimize IVF outcome. In the present opinion paper we present a simplified approach to controlled ovarian hyperstimulation protocol (COH), which combines the benefits of the ultrashort flare GnRH agonist/GnRH antagonist protocol and the personalized tailored mode and timing of ovulation triggering, aiming to improve IVF outcome while eliminating of severe OHSS.In patients at risk to develop severe ovarian hyperstimulation syndrome (OHSS), GnRH agonist (GnRHa) trigger if offered for final follicular maturation.

We describe a case of normal responder patients with repeated implantation failure who was offered the combination of the ultrashort GnRH-ag/ GnRH-ant COH protocol, followed by endometrial injury and a subsequent natural cycle frozen-thawed embryos transfer. The patient conceived following the natural FET cycle that was supported by luteal daily progesterone, with the additional single injection of HCG and GnRH-agonist, on day of ET and 4 days later, respectively. This combined approach seems to be a valuable tool in the armamentarium for treating normal responder patients with repeated implantation failures and should be further examined in large randomized controlled trials.

Background: This study compares the microdose flare-up protocol to the ultrashort gonadotropinreleasing hormone (GnRH) agonist flare combined with the fixed multidose GnRH antagonist protocol in poor responders undergoing ovarian stimulation.
Materials And Methods: In this randomized clinical trial, 120 women who were candidates for assisted reproductive techniques (ART) and had histories of one or more failed in vitro fertilization (IVF) cycles with three or fewer retrieved oocytes were prospectively randomized into two groups. Group I (60 patients) received the microdose flare-up regimen and group II (60 patients) received the ultrashort GnRH agonist combined with fixed GnRH antagonist.

Objective: To evaluate, whether Gonadotropin-releasing hormone-agonist (GnRH-agonist or GnRH-ag) trigger in patients undergoing the ultrashort GnRH-ag/GnRH-antagonist (GnRH-ant) protocol is as effective as in patients at high risk to develop severe ovarian hyperstimulation syndrome (OHSS), who undergo the multidose GnRH-ant protocol.
Design: Cohort study.
Setting: University hospital.
