Cetrorelix

Cetrorelix is a synthetic hormone used primarily in assisted reproductive technology (ART) to prevent premature ovulation in women undergoing controlled ovarian stimulation. By delaying ovulation, it helps in improving the chances of successful egg retrieval and fertilization during procedures like in-vitro fertilization (IVF).

Uses of Cetrorelix

• Prevention of premature luteinizing hormone (LH) surges in women undergoing controlled ovarian hyperstimulation during fertility treatments

How Cetrorelix works

Cetrorelix is a gonadotropin-releasing hormone (GnRH) antagonist. It works by directly blocking the action of GnRH at the pituitary gland, thereby reducing the secretion of LH. This helps prevent premature ovulation, allowing the eggs to mature properly before retrieval.

Benefits of Cetrorelix

• Prevents premature ovulation during ART
• Improves success rates of egg retrieval
• Allows precise timing of ovulation induction

How to take Cetrorelix

Cetrorelix is administered as a subcutaneous injection under the skin, typically in the abdominal area. It is given during the mid-to-late follicular phase of the ovarian stimulation cycle, as directed by a fertility specialist.
