How does the timing of final maturation induction impact egg retrieval success in IVF?

The timing of hCG administration for final oocyte maturation significantly influences IVF success, as inaccurate timing can lead to premature or over-mature eggs, affecting fertilization rates and embryo quality.
The timing of hCG administration is crucial as it needs to align precisely with egg maturity, typically around 36 hours before retrieval, to optimize egg yield and IVF success.
Optimal timing for hCG in IVF is critical; it’s given 34-36 hours before egg retrieval to ensure that eggs are mature enough to be fertilized but not overly mature, which could affect viability.
Administration timing of hCG or GnRH agonists influences oocyte viability—ideally 36 hours before retrieval to maximize mature, healthy eggs, enhancing fertilization rates and embryo quality.
