Cetrorelix uses in fertility treatment
Cetrorelix is a medication used in assisted reproduction to control the timing of ovulation. It helps prevent premature (early) release of an egg during ovarian stimulation. This makes it easier for clinicians to time egg retrieval after giving fertility injections.
What it’s used for specifically (common clinical use)
Cetrorelix is used during in vitro fertilization (IVF) and other controlled ovarian stimulation cycles, where patients take gonadotropins to grow multiple follicles and then need to avoid an untimely LH surge that can trigger ovulation too early.
How it works in the treatment cycle
Cetrorelix is a GnRH (gonadotropin-releasing hormone) antagonist. By blocking GnRH signaling, it suppresses the luteinizing hormone (LH) surge that would otherwise lead to ovulation before the planned procedure.
Alternatives if you’re comparing “what it’s used for”
In similar fertility protocols, some clinics use other GnRH antagonists (same general purpose: preventing premature LH surge) or GnRH agonist protocols, depending on the patient’s risk factors and the clinic’s approach.
