• Avoid wasting embryos and increase the success rate of IVF treatment. In the conventional ovulation-promoting IVF cycle, because the number of embryos obtained usually exceeds the number of transplants, the extra embryos such as cryopreservation can significantly reduce the cost of the next treatment cycle.
  • Reduce the number of embryo transfers and the incidence of multiple pregnancy.
  • Prevent the occurrence of severe ovarian hyperstimulation syndrome (OHSS). Pregnancy can significantly aggravate the severity and duration of OHSS. For patients with obvious OHSS tendency on the day of transplantation in the IVF-ET cycle, giving up fresh embryo transfer can significantly reduce the occurrence of severe OHSS.
  • Save fertility. Because malignant tumors and other diseases need to be treated with chemotherapy or radiotherapy, oocytes can be taken out and fertilized to form embryos before treatment and cryopreserved. After the disease is cured, embryo transplantation can be performed.
