Alongside an increase in the number of ART cycles performed, an increase was also observed in the number of egg freezing cycles, from 24,560 in 2021 to 29,803 in 2022. This data indicated a rise in patients seeking fertility services despite hostile legislation and threats of political interference.
Elective single embryo transfer, a method of decreasing multiple birth risk, has also been increasingly selected across all age groups. This has led the rate of multiple births to decrease from 5% in 2021 to 4% in 2022.
In SART members clinics, transferal of a single embryo to patients was reported in 70.7% of all cycles in 2021 and 73.9% of all cycles in 2022. A significant increase in singletons among babies born by ART has also been observed, at almost 96% in 2022 vs only 80% in 2015.
Differences among age groups was also reported in the national summary report.2 The rate of live births per intended egg retrieval was 43.1% among patients aged under 35 years, vs 31% among those aged 35 to 37 years and 19% among those aged 38 to 40 years. Among patients aged over 42 years, the rate was only 3.2%.
