Brief Summary
Ovarian hyperstimulation syndrome (OHSS) is one of the most dangerous complications of assisted reproduction technology (ART), described in approximatively 3 to 10% of stimulation cycles although an underestimation of the real incidence has been suggested. The use in clinical practice of GnRH antagonist has made it possible to perform the trigger with GnRH analogues, with the advantage of considerably reducing the risk of OHSS.

Study Arms (2)
First fresh embryo transfer (group A)
The two groups analysed were defined according to the modality of first embryo transfer: cycles in which a fresh ET was performed at first, after a dual triggering or a rescue protocol (Group A) and cycles where a frozen-thawed ET was performed at first, after being chosen a freeze-all strategy (Group B).
First cryopreserved embryo transfer (group B)
The two groups analysed were defined according to the modality of first embryo transfer: cycles in which a fresh ET was performed at first, after a dual triggering or a rescue protocol (Group A) and cycles where a frozen-thawed ET was performed at first, after being chosen a freeze-all strategy (Group B).
Interventions
measure of ongoing pregnancy rate, delivery rate, abortion rate, ectopic pregnancy rate, multiple birth rate, ovarian hyperstimulation syndrome incidence, drop out rate
Eligibility Criteria
The study database includes all Oocyte Retrievals (OR) performed between 01/01/2012 and 31/12/2020 at Humanitas Fertility Center after antagonist protocol stimulation and trigger with GnRH agonist.
You may qualify if:
- patients undergoing ART cycle with antagonist protocol stimulation and trigger with GnRH agonist
- patients are believed at risk of OHSS at time of trigger based on size and number of follicles developed (≥18 follicles with diameter 12 mm at induction).
You may not qualify if:
- hypogonadotropic hypogonadism
- other ART protocols
- any patient that underwent freeze-all strategy in order to perform pre-implantation genetic testing (PGT)
- oncological or deferring motherhood freezing procedures
