Cryopreservation of human eggs and embryos has led to 163 reported pregnancies and 65 births as of 1986. Further analysis is needed to understand the full impact of these fertility treatments.

Area of Science:

  • Reproductive Medicine
  • Embryology
  • Cryobiology

Background:

  • Cryopreservation techniques for human oocytes and embryos have advanced significantly.
  • Assisted reproductive technologies (ART) increasingly utilize cryopreservation.
  • Early data collection on cryopreservation outcomes is crucial for evaluating efficacy.

Purpose of the Study:

  • To survey and summarize the outcomes of human embryo and oocyte cryopreservation reported by various fertility centers.
  • To assess the initial success rates of pregnancies and births resulting from cryopreserved human gametes and embryos.
  • To highlight the need for comprehensive analysis of factors influencing cryopreservation success.

Main Methods:

  • A survey was conducted, collecting data from 24 contributing groups.

  • Data focused on reported replacements of cryopreserved embryos up to the end of 1986.
  • Pregnancy and birth data were tabulated from the collected reports.

    • Main Results:

    • A total of 163 pregnancies were reported.
    • 65 live births have resulted from these cryopreserved embryos.
    • An additional 61 pregnancies were ongoing at the time of the survey's tabulation.

    Conclusions:

    • Cryopreservation of human embryos and oocytes has demonstrated a positive impact on infertility treatment.
    • The reported success rates indicate the viability of freezing and thawing techniques.
    • A thorough analysis of all variables affecting cryopreservation outcomes is essential for future improvements.
