Key Factors Affecting Success Rates

  1.  Age of the egg provider – younger eggs generally yield higher success.

  2. Egg quality & quantity – ovarian reserve, response to stimulation.

  3. Embryo quality – influenced by lab environment and embryologist expertise.


  4. Uterine health & implantation conditions – uterine lining, prior surgeries, fibroids.

  5. Male factor & sperm quality – though less age‐driven, still contributes.

  6. Lifestyle factors – BMI, smoking, sleep, stress, nutrition.

  7. Clinic protocols & lab technology – important but just one piece of the whole picture.
