Rescue IVF and coasting with the use of a GnRH antagonist after ovulation induction.
The major risks of exogenous gonadotrophin therapy for ovulation induction in a patient with polycystic ovaries (PCO) are multiple pregnancies and ovarian hyperstimulation syndrome (OHSS). This case report describes a 23-year-old patient, who was referred to the Centre for Reproductive Medicine in Brussels because of a high risk of developing OHSS and rising LH following ovulation induction with a low-dose step-up protocol using gonadotrophins. After counselling the patient, the decision was made to perform a rescue IVF cycle. The patient was first coasted with 0.25 mg ganirelix; the serum oestradiol concentrations decreased and the LH peak was successfully suppressed. No OHSS occurred. An ongoing twin pregnancy was achieved after the transfer of two embryos. This case report demonstrates the feasibility of coasting with LH-releasing hormone (LHRH) antagonists (0.25 mg ganirelix) and the usefulness of the antagonists for ovulation induction cycles in patients who need rescue IVF.
