The injection for egg release is called a trigger shot, which contains human chorionic gonadotropin (hCG). This medication is typically used in conjunction with other fertility drugs to stimulate the ovaries to produce and release an egg. It is often given after a period of follicle monitoring to ensure that the follicle is mature and ready for release. The hCG injection mimics the natural surge of luteinizing hormone (LH) that occurs during ovulation, prompting the follicle to release the egg.
Example: In an IVF cycle, the trigger shot is administered before egg retrieval to induce the final maturation of the eggs and initiate ovulation.
In addition to the trigger shot, other injectable medications used for ovulation induction include:
- Follicle-stimulating hormone (FSH): Used to stimulate the growth of multiple follicles in the ovaries.
- Luteinizing hormone (LH): Used to help the follicle mature and release the egg.
These medications are typically prescribed by a fertility specialist and are used to treat infertility caused by ovulation disorders, such as polycystic ovary syndrome (PCOS).
