Yes, there are different protocols in controlled ovarian stimulation. As for the protocol with antagonists (also called short protocol), the use of Cetrotride (cetrorelix acetate) is included, but other antagonist drugs such as Orgalutran (ganirelix) can also be used. As for the long protocol, for pituitary gland arrest, other drugs called agonists are used. Both protocols have demonstrated the same reproductive efficacy, but it is chosen according to the patient's profile.
Can I still undergo IVF when I'm allergic to Cetrotide?
