Learn about TrackMyIVFFrequently Asked Questions
What is ganirelix used for in IVF?
Ganirelix is a GnRH antagonist that prevents your pituitary gland from releasing LH too early, which would cause premature ovulation before your egg retrieval. It is used during the stimulation phase once your follicles are growing.
Does ganirelix need to be refrigerated?
No, ganirelix can be stored at room temperature, which makes it easier to travel with than medications requiring refrigeration. Check the package insert for your specific product, as guidelines may vary slightly.
Is ganirelix the same as Cetrotide?
Ganirelix and Cetrotide (cetrorelix) are both GnRH antagonists with the same purpose in IVF cycles, but they are different molecules. Your clinic may use one or the other depending on their preference and your insurance coverage. They work in a similar way.
How will I know if ganirelix is working?
Your clinic monitors your response through bloodwork (checking LH and estradiol levels) and ultrasound. As long as your LH stays suppressed during monitoring, the medication is doing its job.
