Cetrorelix is used in women having certain fertility treatments (controlled ovarian stimulation). This medication prevents eggs from being released too early (premature ovulation) by blocking the hormone (gonadotropin-releasing hormone-GnRH) that causes eggs to be released from the ovaries. This gives the eggs time to develop properly.
This medication is usually used with another hormone (human chorionic gonadotropin-hCG) to help you become pregnant. HCG is used to cause the growth and release of a mature egg (ovulation).
This medication must not be used if you are already pregnant. Your doctor may order a pregnancy test before your first dose.

When an ultrasound shows that you are ready, a second medication (hCG) is usually injected to cause the eggs to mature and release (ovulation).
