Brief Summary
Women who undergo assisted reproduction technology (ART) treatment will be eligible for this study. The goal of this randomized clinical trial is to compare the outcomes of ART treatment between women who have 36 and 38 hours interval between the administration of ovulation trigger (ovulation trigger medication initiates oocyte maturation and makes it possible for the egg to be collected by aspiration, during a procedure called oocyte pick-up, OPU) and OPU. The main questions it aims to answer are, does prolonging the trigger-OPU interval to 38-hours improve:
- Maturation rate
- Fertilization rate
- Blastulation rate
- Premature ovulation rate
- Positive pregnancy test rate
- Clinical pregnancy rate
- Live birth rate compared to 36-hours interval?

Study Arms (2)
36-Hour Group
ACTIVE COMPARATORThe women randomized to this group will undergo oocyte pick-up procedure 36 hours after the injection of the ovulation triggering agent. The choice for ovulation trigger agent is at the discretion of the treating physician. The intervention is not the drug but the interval.
38-Hour Group
EXPERIMENTALThe women randomized to this group will undergo oocyte pick-up procedure 38 hours after the injection of the ovulation triggering agent. The choice for ovulation trigger agent is at the discretion of the treating physician. The intervention is not the drug but the interval.
Interventions
36-hour duration between ovulation triggering and oocyte pick-up procedure
38-hour duration between ovulation triggering and oocyte pick-up procedure
Eligibility Criteria
You may qualify if:
- To undergo assisted reproductive technology (ART) treatment and planning to undergo embryo transfer procedure within 6 months of oocyte collection
- Female partner to be between 18-42 years old at the time of informed consent
- Both partners to consent to participate in the study and be legally eligible to give consent.
You may not qualify if:
- Female partner to have participated in the study previously.
- Female partner to have a body mass index of 35 kg/m2 or above.
- Female partner to have a systemic disease that may affect ART or pregnancy outcomes (e.g. antiphospholipid syndrome, severe liver dysfunction, diabetes mellitus, history of venous thrombosis, advanced renal or cardiac diseases).
- Presence of congenital uterine anomaly (1-Women whose uterine anomalies are surgically corrected are not excluded; 2- Arcuate uterus is not accepted as a congenital uterine anomaly).
- Presence of submucous or intramural fibroid that distorts the endometrial cavity.
- Diagnosis of stage 3 or 4 endometriosis in the female partner.
- Female partner planned to undergo double ovarian stimulation.
- Known karyotype anomaly in at least one of the partners.
- Diagnosis of azoospermia (no sperm cells in the ejaculate) in the male partner.
- History of recurrent implantation failure \[defined according to the scoring system by Ata et al in 2021 available at https://bit.ly/3huVLOn (Ata B, Kalafat E, Somigliana E. A new definition of recurrent implantation failure on the basis of anticipated blastocyst aneuploidy rates across female age. Fertil Steril. 2021;116(5):1320-1327. doi:10.1016/j.fertnstert.2021.06.045\].
- History of recurrent pregnancy loss \[defined as a history of 2 or more biochemical/clinical pregnancy losses, in accordance with the European Society of Human Reproduction and Embryology(ESHRE) Guideline on the management of recurrent pregnancy loss issued on 1 February 2023, available at https://www.eshre.eu/Guidelines-and-Legal/Guidelines/Recurrent-pregnancy-loss.aspx\].

- Masking Details
- Only the head-nurse and the patient will not be masked, since one will randomize the patient to a group and give her instructions on how to use the medication, and the other will apply the injection herself. However, allocation will be concealed from the the laboratory team, treating physicians, outcome assessors and investigators. They will not be given information about when the patient applied the injection, and the patient will be instructed not to reveal information regarding her use.
