Pregnyl® (Intramuscular Injection)

About Pregnyl®

Pregnyl® is an injectable medication that contains a naturally occurring hormone called human chorionic gonadotropin (hCG). Pregnyl® is known as a “trigger shot” because it is prescribed to women as a single injection to induce the final maturation and release of eggs after stimulation with gonadotropin medications (Follistim®, Gonal-f®, or Menopur®) During IVF, it is taken approximately 36 hours prior to egg retrieval to simulate the natural surge of luteinizing hormone (LH) that triggers ovulation in the normal menstrual cycle. Pregnyl® may also be prescribed to men to increase testosterone and sperm production.

Pregnyl® comes in a vial containing 10,000 units of powdered medication that must be mixed with sterile solvent before injecting. Pregnyl® injections can be injected under the skin (subcutaneous) or into the muscle (intramuscular), as instructed by your doctor.
