Re: Antagonist Protocol - newbie question
I did an antagonist protocol with ivf. Here is some good info for you.
https://www.advancedfertility.com/ivf-stimulation-antagonist.htm
I did an antagonist protocol...started with estrogen pills for 2 weeks then went in to follistim/menopur...then added ganirelex...then Ovidrel before the ER. They did this with me because I have DOR and don't start out with a ton of follicles (usually around 10 total)...the antagonist protocol is a more aggressive treatment and used with ladies they think might be poor responders. From what I understand if you have PCOS or are at risk for hyper-stimulation than they wouldn't do this protocol.
Below is from www.ivfspecialist.net
The final type of protocol is known as the antagonist protocol. In this treatment, a medication other than Lupron is used to supress the pituitary gland and prevent ovulation. This newer type of medication is called a GNRH antagonist. There are two brands of this medication: Ganarelix and Cetrotide. These medications do not have a flare effect. In fact, the supression of the pituitary gland is almost immediate. This is a big advantage since the IVF specialist can start the medication after the ovaries have been stimulated instead of a two week pre-treatment period as is seen with the Lupron. This makes the antagonist IVF protocol much shorter than the Lupron protocol.
