  1. Data are presented as mean values and standard error
  2. For one participant, oocyte maturation rate = number of oocytes at MII (metaphase II oocytes, 1st polar body) stage/ total number of oocytes retrieved
  3. Fertilization rate = number of fertilized embryos/total number of oocytes retrieved
  4. Cleavage rate = number of cleavage embryos/number of 2PN
  5. High-quality embryo rate = number of high-quality embryos (grade I and II embryos)/number of 2PN
  6. Biochemical pregnancy rate refers to the cumulative biochemical pregnancy rate in the oocyte cycle during which the samples were collected, that is, the number of biochemical pregnancies of the participant/the number of embryos transplanted in this cycle
  7. Clinical pregnancy rate refers to the cumulative clinical pregnancy rate in the oocyte cycle during which the samples were collected, that is, the number of clinical pregnancies of the participant/the number of embryos transplanted in this cycle
