Objective: To describe our experience with random-start IVF with the use of GnRH agonist for final oocyte maturation, to reduce the risk of ovarian hyperstimulation syndrome.
Design: Case series.
Setting: University-based center for reproductive endocrinology and infertility.
Patient(s): Patients with a new diagnosis of cancer who presented with a narrow time frame for IVF before initiating cancer therapy.
Intervention(s): Random-start GnRH antagonist cycles with GnRH agonist trigger for final oocyte maturation.
Main outcome measure(s): Number of oocytes retrieved, fertilization rate, rates of ovarian hyperstimulation syndrome.
Results: Cycles were started in the late follicular or luteal phase, and the duration of controlled ovarian hyperstimulation ranged between 8-13 days. A total of 14-40 oocytes were retrieved and 5-20 embryos cryopreserved for each patient.
Conclusion(s): Random-start IVF is a reasonable option for fertility preservation in those cancer patients for whom the treatment window may be narrow. In addition, the use of a GnRH agonist for final oocyte maturation may decrease the potential risk of ovarian hyperstimulation syndrome.
