Key Factors That Affect IVF Success

  • Maternal Age: The single most important determinant. Egg quality declines with age.
  • Egg Quality & Ovarian Reserve (AMH): Higher AMH means more eggs retrieved and better choices for transfer.
  • Sperm Quality: Morphology, motility, and DNA fragmentation index impact fertilization rates.
  • Uterine Health: Polyps, fibroids, or thin endometrium reduce implantation rates.
  • Embryology Lab Standards: Air quality, culture media, and incubator technology directly impact embryo viability.
  • Stimulation Protocol: Individualized protocols vs. routine ("cookie-cutter") approaches make a measurable difference.
  • Number of Eggs Retrieved: More mature eggs = better embryo selection = higher success chance.
  • Blastocyst vs Cleavage Stage Transfer: Day-5 blastocyst transfer generally yields higher implantation rates than Day-3.
  • PGT-A Testing: Eliminates chromosomally abnormal embryos, reducing miscarriage risk and improving live birth rates.
