**STUDY ** What are the data and trends of ART and IUI cycle numbers and their outcomes, and of fertility preservation (FP) interventions, reported in 2020 as compared to previous years? **SUMMARY ** This 24th ESHRE report highlights the number of ART treatment cycles and children born over the years, showing a decline in the total number of treatment cycles, when comparing 2020 with 2019, alongside a decline in twin deliveries owing to a decrease in transfers of multiple embryos; however, fresh IVF or ICSI cycles and frozen embryo transfers (FET) showed similar pregnancy rates, and the reported IUI cycle numbers decreased while maintaining stable outcomes. **WHAT ** ART aggregated data generated by national registries, clinics, or professional societies have been gathered and analyzed by the European IVF Monitoring (EIM) consortium since 1997 and reported in a total of 23 manuscripts published in *Human Reproduction* and *Human Reproduction Open*. **STUDY DESIGN, SIZE, ** Data on medically assisted reproduction (MAR) from European countries are collected by EIM for ESHRE each year. The data on treatment cycles performed between January 1 and December 31, 2020, were provided by either national registries or registries based on initiatives of medical associations and scientific organizations or committed persons in the 44 countries that are members of the EIM Consortium. **PARTICIPANTS/MATERIALS, SETTING, ** Overall, 1440 clinics offering ART services in 41 countries reported 923 318 treatment cycles (−14%; in 2019: 1 077 813), including 135 231 with IVF, 356 408 with ICSI, 305 373 with FET, 57 051 with preimplantation genetic testing (PGT), 64 007 with oocyte donation, and 4895 cycles using frozen oocytes. A total of 1288 institutions reported data on IUI cycles using either husband/partner's semen (IUI-H; n = 112 663) or donor semen (IUI-D; n = 38 839) in 30 and 21 countries, respectively. Sixteen countries reported 29 566 interventions in pre-and post-pubertal patients for FP, including oocyte, ovarian tissue, semen, and testicular tissue banking. **MAIN ** In 24 countries (21 in 2019) in which all ART clinics reported to the registry, 356 427 treatment cycles were registered for a total population of approximately 268 million inhabitants in these countries, allowing the best estimate of a mean of 1330 cycles performed per million inhabitants (range: 142–3230). Among the reporting countries, for IVF, the clinical pregnancy rates (PR) per aspiration were similar to that in 2019 (22.1% versus 21.8% in 2019). For ICSI, the corresponding PRs showed similar trends (20.0% in 2020 versus 20.2% in 2019). When freeze-all cycles were excluded from the calculations, the clinical PRs per aspiration were 26.4% (28.5% in 2019) and 25.6% (26.2% in 2019) for IVF and ICSI, respectively. After oocyte donation, the PR per embryo transfer was 51.3% (50.5% in 2019) with freshly donated oocytes and 45.7% (44.8% in 2019) with thawed oocytes. After FET, the PR per thawing was 34.9% (versus 35.1% in 2019). In fresh cycles of both IVF and ICSI, the trend towards the transfer of fewer embryos continued with the transfer of 1, 2, 3, and ≥4 embryos in 57.2%, 37.8%, 4.8%, and 0.2%, of all treatments, respectively (corresponding to 55.4%, 39.9%, 2.6%, and 0.2% in 2019). This resulted in a reduced proportion of twin delivery rates (DRs) of 10.9% (11.9% in 2019) and a similar triplet DR of 0.2%. In FET cycles in 2020, the twin and triplet DRs were 7.9% and 0.1%, respectively (versus 8.9% and 0.1% in 2019). While the number of IUI cycles in 2020 decreased from 2019, the DRs remained stable at 8.8% after IUI-H (8.7% in 2019) and at 12.5% after IUI-D (12.1% in 2019). Twin and triplet DRs after IUI-H were 7.9% and 0.4% (in 2019: 8.7% and 0.4%) and 5.7% and 0.1% after IUI-D (in 2019: 6.2% and 0.2%), respectively. Data on FP were provided by 16 countries (18 in 2019), reporting a total of 29 566 interventions (24 139 in 2019). Cryopreservation of ejaculated sperm (n = 21 864 versus n = 11 592 in 2019) and cryopreservation of oocytes (n = 6077 versus n = 10 784 in 2019) were the most frequently reported forms of FP. **LIMITATIONS, ** Caution with the interpretation of results should remain as data collection systems and completeness of reporting vary among European countries.

What were the rates of utilization, effectiveness, and safety for assisted reproductive technology (ART) throughout the world in 2017 and 2018, and what trends were observed? The total reported number of ART fresh and frozen cycles conducted in 83 participating countries was 2 913 498 in 2017 and 3 303 505 in 2018, with 5-year trends including an increasing proportion of cycles utilizing frozen embryo transfer (FET) and an increasing number of cycles utilizing pre-implantation genetic testing (PGT). Prior reports from the International Committee Monitoring ART (ICMART) have reported on the utilization, effectiveness, and safety of ART from participating countries, with an increase in the number of cycles and number of participating countries over time. These reports have described regional differences in the utilization of ART overall, as well as differences in the utilization of specific practices such as ICSI, PGT and single embryo transfer. Past reports demonstrated that rates of delivery per cycle have increased and rates of multiple gestations have decreased over time. STUDY DESIGN, SIZE, This retrospective, cross-sectional survey describes ART procedures performed globally in 2017 and 2018. Data were submitted to ICMART by participating countries from national or regional registries. PARTICIPANTS/MATERIALS, SETTING, There were 83 countries which provided data for cycles performed in 2017 or 2018, with the majority of countries providing data for both years. Aggregate data are reported for each participating country and analysed using methods developed by ICMART to calculate measures of utilization, effectiveness, and safety. MAIN A total of 2 913 498 cycles and 671 012 babies born were reported for treatment performed in 2017, increasing to 3 303 505 cycles and 728 383 babies born for treatment performed in 2018. After imputing data for non-reporting centres in reporting countries, the estimated number of cycles performed in 2017 was 3 107 188 resulting in an estimated 814 588 babies. For 2018, the estimated number of cycles was 3 568 635 resulting in an estimated 870 814 babies. Utilization of ICSI for autologous fresh non-PGT cycles declined slightly compared with 2014 (54.6% in 2017 and 57.3% in 2018 compared with 64.8% in 2014). The percentage of transfers which were of frozen embryos was 55.7 % in 2017 and 57.9% in 2018, up from 38.9% in 2014. Among all countries, including those which reported no 'freeze all' cycles, the percentage of 'freeze all' cycles was 30.5% in 2017 and 32.7% in 2018, up from 13.1% in 2014. In countries reporting at least one retrieval cycle in which all embryos were frozen, the percentage of retrievals with no fresh embryo transfer increased (36.2% in 2017 and 36.8% in 2018, up from 20.1% in 2014). The number of PGT cycles in 2018 (172 247) was nearly 5-fold higher than the number reported in 2014 (36 512) with wide regional variation in utilization of PGT observed. In 2017, the delivery rate for autologous oocytes was 23.5% per oocyte retrieval, with a cumulative delivery rate of 36.4% per retrieval (excluding cycles which utilized PGT). The delivery rates per embryo transfer were 31.8% per autologous fresh transfer, 32.5% per autologous frozen transfer, and 47.3% per transfer after PGT. The delivery rate for transfers utilizing donor oocytes was 33.1% (combined fresh transfer and frozen transfers). In 2018, the delivery rate for autologous oocytes was 23.8% per oocyte retrieval, with a cumulative delivery rate of 37.3% per retrieval (excluding cycles which utilized PGT). The delivery rates per embryo transfer were 31.3% per autologous fresh transfer, 31.9% per autologous frozen transfer, and 48.4% per transfer after PGT. The delivery rate for transfers utilizing donor oocytes was 34.3%. The multiple delivery rate with autologous fresh transfer was 19.7% in 2017, and 18.3% in 2018. For autologous FET, the multiple delivery rate was 16.2% in 2017, and 14.9% in 2018. With oocyte donation (combined fresh and frozen embryo transfers), the multiple delivery rate was 15.9% in 2017, and 13.4% in 2018. Finally, the multiple delivery rate for cycles utilizing PGT was 6.9% in 2017 and 5.5% in 2018. LIMITATIONS, The data and analysis presented are dependent on the quality and completeness of the data submitted to ICMART, which varies globally. There is little data from the Middle East and some countries in Asia. It is important to note that delivery rates per transfer after PGT required the availability of embryos suitable for transfer, and therefore should not be interpreted as suggesting that PGT increases the overall success of ART per oocyte retrieval. Because of an updated methodology in the calculation of delivery rates and number of babies born, direct comparisons with past reports for these metrics cannot be made. Data are observational and it

Are there any changes in the treatments involving ART and IUI initiated in Europe during 2013 compared with previ- ous years?
An increase in the overall number of ART cycles resulting from a higher number of countries reporting data was
evident, the pregnancy rates (PRs) in 2013 remained stable compared with those reported in 2012, the number of transfers with multiple
embryos (3+) was lower than ever before yet the multiple delivery rates (DRs) remained unchanged, and IUI activity and success rates were
similar to those of last years.
Since 1997, ART data in Europe have been collected and reported in 16 manuscripts, published in Human Reproduction.
STUDY DESIGN, SIZE, Retrospective data collection of European ART data by the European IVF-monitoring Consortium
for ESHRE. Data for cycles between 1 January and 31 December 2013 were collected from National Registers, when existing, or on a voluntary basis by personal information.
PARTICIPANTS/MATERIALS, SETTINGS, From 38 countries (+4 compared with 2012), 1169 clinics reported
686 271 treatment cycles including 144 299 of IVF, 330 367 of ICSI, 154 712 of frozen embryo replacement (FER), 40 244 of egg donation
(ED), 247 of IVM, 9791 of PGD/PGS and 6611 of frozen oocyte replacements. European data on intrauterine insemination using husband/
partner’s semen (IUI-H) and donor semen (IUI-D) were reported from 1095 IUI labs in 22 countries. A total of 175 467 IUI-H and 43 785
IUI-D cycles were included.
MAIN In 17 countries where all clinics reported to their ART register, a total of 374 177
ART cycles were performed in a population of around 310 million inhabitants, corresponding to 1175 cycles per million inhabitants (range,
235–2703 cycles per million inhabitants). † ESHRE Pages content is not externally peer reviewed. This manuscript has been approved by the Executive Committee of ESHRE.

For Permissions, please e-mail: journals.permissions@oup.com For all IVF cycles, the clinical PRs per aspiration and per transfer were stable with 29.6% (29.4% in 2012) and 34.5% (33.8% in 2012),
respectively. For ICSI, the corresponding rates also were stable with 27.8% (27.8% in 2012) and 32.9% (32.3% in 2012). In FER-cycles, the PR
per thawing/warming increased to 27.0% (23.1% in 2012). In ED cycles, the PR per fresh transfer increased to 49.8% (48.4% in 2012), to
38.5% (35.9% in 2012) per thawed transfer, and to 46.4% for transfers after FOR (45.1% in 2012). The DRs after IUI remained stable at 8.6%
(8.5% in 2012) after IUI-H and was slightly lower after IUI-D (11.1% versus 12.0% in 2012).
In IVF and ICSI cycles, 1, 2, 3 and 4+ embryos were transferred in 31.4, 56.3, 11.5, and 1.0% of the cycles, respectively (corresponding
numbers were 30.2, 55.4, 13.3 and 1.1% in 2012). The proportions of singleton, twin and triplet deliveries after IVF and ICSI (added together)
were 82., 17.5 and 0.5%, respectively, resulting in a total multiple DR of 18.0% compared to 17.9% in 2012. In FER-cycles, the multiple DR
was 12.8% (12.5% twins and 0.3% triplets), nearly the same as in 2012 (12.5, 12.2 and 0.3% respectively).
Twin and triplet DRs associated with IUI cycles were 9.5%/0.6% and 7.5%/0.3%, following treatment with husband/donor semen,
respectively.
LIMITATIONS, The method of reporting varies among countries, and registers from a number of countries have been unable to provide some of the relevant data such as initiated cycles and deliveries.
