What are the Injections for Egg Donation?

Published in Medical Procedures 2 mins read

Egg donation involves a series of injections to stimulate the ovaries to produce multiple eggs. These injections are crucial for increasing the chances of retrieving a sufficient number of eggs for fertilization.

Here's a breakdown of the common injections used in egg donation:

1. Follicle-Stimulating Hormone (FSH)

  • Purpose: FSH stimulates the growth and development of follicles, which contain the eggs.
  • Administration: FSH is typically administered daily via subcutaneous injection.
  • Examples: Gonal-f, Follistim AQ, Bravelle

2. Luteinizing Hormone (LH)

  • Purpose: LH triggers ovulation, the release of the egg from the follicle.
  • Administration: LH is often combined with FSH, especially in the latter stages of stimulation.
  • Examples: Luveris, Ovidrel

3. Human Chorionic Gonadotropin (hCG)

  • Purpose: hCG acts as a final trigger for ovulation. It mimics the LH surge that naturally occurs before ovulation.
  • Administration: hCG is given as a single injection, usually 36 hours before egg retrieval.
  • Examples: Novarel, Pregnyl

4. Gonadotropin-Releasing Hormone (GnRH) Analogs

  • Purpose: GnRH analogs, like Lupron, suppress the natural production of FSH and LH, preventing premature ovulation.
  • Administration: GnRH analogs are often given daily via subcutaneous injection.

5. Other Medications

  • In addition to the above, other medications may be prescribed, such as:
    • Antagonists: These medications block the LH surge, preventing premature ovulation.
    • Pain relievers: These are used to manage discomfort associated with ovarian stimulation.

Remember: The specific injections and dosages used in egg donation will vary based on individual factors, such as age, medical history, and response to medications. It's crucial to discuss any questions or concerns with your doctor.
