Increase in IVF Procedures Leads to Record Number of Embryos Created in South Korea

The number of couples attempting to conceive through in vitro fertilization (IVF) has surged, resulting in the creation of approximately 800,000 embryos annually. The number of embryo transfers has also surpassed 200,000. According to data received by Kim Yoon, a member of the National Assembly's Health and Welfare Committee from the Democratic Party, a total of 783,860 new embryos were created last year, marking an 83.2% increase compared to 427,818 embryos in 2019.

The annual number of embryos generated has steadily risen from 334,687 in 2016 to 550,724 in 2021, and last year saw a 30.7% increase from the previous year’s total of 599,851 embryos.

The number of embryos actually used for implantation has also grown, with 201,496 embryos transferred last year, a 31.9% increase from 152,761 in 2019. However, the number of embryos that were not implanted and subsequently discarded has also risen. Last year, 533,266 embryos were disposed of, which is a staggering 104.7% increase from 2019. During IVF procedures, typically 1 to 3 embryos are implanted based on the woman's age and health status. If pregnancy occurs, the remaining embryos can be stored for future attempts, while those not used can be utilized in subsequent cycles. Embryos can be frozen for up to five years, after which they may be discarded if the couple chooses.

While IVF is becoming more established in South Korea, there are calls for improvements in related regulations. A notable case involved actress Lee Si-young, who implanted frozen embryos without her ex-husband's consent during their marriage. Current laws require mutual consent for embryo creation, but there is no explicit regulation requiring both parties' agreement for implantation. A representative from the Ministry of Health and Welfare stated, 'We plan to discuss with experts whether there is a need to improve the procedures.'
