    Summary · context
    Eligible patients were ≤40 years old, with an antral follicular count of <20 and antimüllerian hormone level of ≤3 ng/mL undergoing elective fertility preservation cycles.
    Summary · context
    As soon as at least three follicles measuring ≥18 mm were observed by ultrasound, patients were randomization to the intervention group (triptorelin 0.2 mg + recombinant human chorionic gonadotropin 250 mcg) or the control group trigger with gonadotropin-releasing hormone agonist (GnRH-a) alone (triptorelin 0.2 mg).
    Summary · context
    Overall, 109 patients were analyzed, 55 in the dual trigger group and 54 in the control arm (GnRH-a).
