This trial will compare the efficacy of two different times of administration of medications for final oocyte maturation, commonly called a "trigger", in cycles of controlled ovarian stimulation.

Who is the study for?
This trial is for adult women aged 18-35 with normal ovarian response, who are undergoing IVF and plan to freeze all embryos reaching the blastocyst stage. They must understand English to consent and can have had previous IVF cycles but only one cycle under this study.Check my eligibility
What is being tested?
The study tests two different timings for administering 'trigger' drugs that help mature eggs in controlled ovarian stimulation during IVF. All participants will have their embryos frozen at the blastocyst stage for future use.See study design
What are the potential side effects?
While specific side effects aren't listed, typical risks may include reactions to medications, discomfort from procedures, hormonal changes affecting mood or physical state, and potential complications from egg retrieval.
