Many factors can interfere with its mechanism, which primarily works by delaying ovulation to prevent pregnancy. Understanding what stops ellaOne from working is critical to ensuring you have the best possible chance of preventing an unintended pregnancy.

The half-life of an hCG injection is typically between 29 and 48 hours, but the hormone can remain detectable in your system for up to two weeks.

In a clinical study, premature luteinizing hormone (LH) surges—the event that triggers ovulation—occurred in less than 1% of women using the standard 250 mcg dose of Fyremadel. This statistic highlights the drug's effectiveness in its intended purpose, making it highly unlikely that you will still ovulate on Fyremadel, especially under proper medical supervision during assisted reproductive technology (ART) cycles.

Since its FDA approval in 1999, ganirelix has been a critical medication in assisted reproductive technology protocols to prevent premature ovulation.
