International Committee for Monitoring Assisted Reproductive Technology world report: assisted reproductive technology, 2015 and 2016.

OBJECTIVE: To report utilization, effectiveness, and safety of assisted reproductive technologies in 2015 and 2016. DESIGN: A retrospective, cross-sectional survey of 3,103 assisted reproductive technology clinics in 74 countries in 2015 and 3,249 clinics in 79 countries in 2016 that submitted cycle and pregnancy outcome data through national and regional registries. SETTING: Seventy-nine countries and >3,000 assisted reproductive technology clinics. PATIENT(S): Patients undergoing assisted reproductive technology procedures. INTERVENTION(S): Assisted reproductive technology. MAIN OUTCOME MEASURE(S): Outcomes on country, regional, and global levels. RESULT(S): Reported for 2015: 2,358,239 cycles with 548,652 infants born; for 2016: 2,807,963 cycles with 647,188 infants born. Estimated in 2015, ≥2,683,677 cycles resulted in >675,134 infants; in 2016, ≥3,100,448 cycles resulted in ≥723,026 infants. Reported cycles represent approximately 80% of global utilization. In 2015 and 2016, 27.6% and 27.8%, respectively, of women undergoing fresh autologous treatment cycles were aged ≥40 years. Frozen-thawed embryo transfer (ET) cycles accounted for 47.0% and 51.9%, respectively, of all ETs in 2015 and 2016. Oocyte donation cycles accounted for 6.7% and 7.1% of all ETs in 2015 and 2016. Intracytoplasmic sperm injection was performed in 57.7% and 56.4% of autologous aspiration cycles in 2015 and 2016, respectively. The cumulative delivery rate per aspiration cycle for fresh and frozen-thawed ET was 32.4% in 2015 and 33.1% in 2016, respectively. The average number of transferred embryos was 1.70 in 2015 and 1.69 in 2016. The proportion of single ETs in fresh autologous cycles increased from 42.1% in 2015 to 44.0% in 2016. The twin delivery rate decreased from 16.0% in 2015 to 14.7% in 2016, and the triplet rate decreased from 0.6% in 2015 to 0.4% in 2016. The proportion of single ETs in frozen-thawed ET autologous treatment cycles was 62.2% in 2015 and 64.2% in 2016, with twin and triplet rates of 10.1% and 0.3% in 2015 and 10.0% and 0.2% in 2016, respectively. CONCLUSION(S): Utilization of assisted reproductive technology treatment and births per cycle increased from 2015 to 2016, although multiple births were reduced. An increasing proportion of frozen-thawed ET cycles, continuing wide variation in use of intracytoplasmic sperm injection, and an increase in single ET rates are reported.

Declining global fertility rates and the implications for family planning and family building: an IFFS consensus document based on a narrative review of the literature.

BACKGROUND: Family-planning policies have focused on contraceptive approaches to avoid unintended pregnancies, postpone, or terminate pregnancies and mitigate population growth. These policies have contributed to significantly slowing world population growth. Presently, half the countries worldwide exhibit a fertility rate below replacement level. Not including the effects of migration, many countries are predicted to have a population decline of >50% from 2017 to 2100, causing demographic changes with profound societal implications. Policies that optimize chances to have a child when desired increase fertility rates and are gaining interest as a family-building method. Increasingly, countries have implemented child-friendly policies (mainly financial incentives in addition to public funding of fertility treatment in a limited number of countries) to mitigate decreasing national populations. However, the extent of public spending on child benefits varies greatly from country to country. To our knowledge, this International Federation of Fertility Societies (IFFS) consensus document represents the first attempt to describe major disparities in access to fertility care in the context of the global trend of decreasing growth in the world population, based on a narrative review of the existing literature. OBJECTIVE AND RATIONALE: The concept of family building, the process by which individuals or couples create or expand their families, has been largely ignored in family-planning paradigms. Family building encompasses various methods and options for individuals or couples who wish to have children. It can involve biological means, such as natural conception, as well as ART, surrogacy, adoption, and foster care. Family-building acknowledges the diverse ways in which individuals or couples can create their desired family and reflects the understanding that there is no one-size-fits-all approach to building a family. Developing education programs for young adults to increase family-building awareness and prevent infertility is urgently needed. Recommendations are provided and important knowledge gaps identified to provide professionals, the public, and policymakers with a comprehensive understanding of the role of child-friendly policies. SEARCH METHODS: A narrative review of the existing literature was performed by invited global leaders who themselves significantly contributed to this research field. Each section of the review was prepared by two to three experts, each of whom searched the published literature (PubMed) for peer reviewed full papers and reviews. Sections were discussed monthly by all authors and quarterly by the review board. The final document was prepared following discussions among all team members during a hybrid invitational meeting where full consensus was reached. OUTCOMES: Major advances in fertility care have dramatically improved family-building opportunities since the 1990s. Although up to 10% of all children are born as a result of fertility care in some wealthy countries, there is great variation in access to care. The high cost to patients of infertility treatment renders it unaffordable for most. Preliminary studies point to the increasing contribution of fertility care to the global population and the associated economic benefits for society. WIDER IMPLICATIONS: Fertility care has rarely been discussed in the context of a rapid decrease in world population growth. Soon, most countries will have an average number of children per woman far below the replacement level. While this may have a beneficial impact on the environment, underpopulation is of great concern in many countries. Although governments have implemented child-friendly policies, distinct discrepancies in access to fertility care remain.

Gender inequality and utilization of ART: an international cross-sectional and longitudinal analysis.

STUDY QUESTION: What is the association between a country's level of gender equality and access to ART, as measured through ART utilization? SUMMARY ANSWER: ART utilization is associated with a country's level of gender equality even after controlling for the level of development. WHAT IS KNOWN ALREADY: Although gender equality is recognized as an important determinant of population health, its association with fertility care, a highly gendered condition, has not been explored. STUDY DESIGN, SIZE, DURATION: A longitudinal cross-national analysis of ART utilization in 69 countries during 2002-2014 was carried out. PARTICPANTS/MATERIALS, SETTING, METHODS: The Gender Inequality Index (GII), Human Development Index (HDI), and their component indicators were modelled against ART utilization using univariate regression models as well as mixed-effects regression methods (adjusted for country, time, and economic/human development) with multiple imputation to account for missing data. MAIN RESULTS AND THE ROLE OF CHANCE: ART utilization is associated with the GII. In an HDI-adjusted analysis, a one standard deviation decrease in the GII (towards greater equality) is associated with a 59% increase in ART utilization. Gross national income per capita, the maternal mortality ratio, and female parliamentary representation were the index components most predictive of ART utilization. LIMITATIONS, REASONS FOR CAUTION: Only ART was used rather than all infertility treatments (including less costly and non-invasive treatments such as ovulation induction). This was a country-level analysis and the results cannot be generalized to smaller groups. Not all modelled variables were available for each country across 2002-2014. WIDER IMPLICATIONS OF THE FINDINGS: Access to fertility care is central to women's sexual and reproductive health, to women's rights, and to human rights. As gender equality improves, so does access to ART. This relation is likely to be reinforcing and bi-directional, with progress towards global, equitable access to fertility care also improving women's status and participation in societies.

ART in Latin America: the Latin American Registry, 2020.

RESEARCH QUESTION: What was the utilization, effectiveness and safety of assisted reproductive technology (ART) in Latin America during 2020? DESIGN: Retrospective collection of multinational data on ART performed by 188 institutions in 16 countries. RESULTS: Overall, 87,732 initiated cycles resulted in 12,778 deliveries and 14,582 births. The major contributors were Brazil (46.0%), Mexico (17.0%) and Argentina (16.8%). However, the highest utilization (cycles/million inhabitants) was Uruguay with 558, followed by Argentina with 490 and Panama with 425 cycles/million. Globally, women aged ≥40 years increased to 34% while women ≤34 dropped to 24.7%. After removing freeze-all cycles, the delivery rate per oocyte retrieval was 14.8% for intracytoplasmic sperm injection and 15.6% for IVF. Single-embryo transfer (SET) represented 38.3% of all fresh transfers, with delivery rate per transfer of 20.0%; this increased to 32.4% for elective SET (eSET) and 34.2% for blastocyst eSET, compared with blastocyst elective double embryo transfer (eDET) of 37.9%. However, multiple births increased from 1% in eSET to 30.5% in eDET. Perinatal mortality increased from 7.7‰ in singletons to 24.4‰ in twins and 64.0‰ in triplets. Frozen embryo transfer (FET) represented 66.6% of all transfers, with a delivery rate/transfer of 29.0%, significantly higher than 23.9% after fresh transfers at all ages (p<0.0001). Preimplantation genetic testing, reported in 8920 cycles, significantly improved delivery rate and decreased miscarriage rates at all ages (p≤0.041), including oocyte donation (p=0.002). Endometriosis was diagnosed in 28.3% of cases. The delivery rate in 5779 women after removal of peritoneal endometriosis was significantly better than tubal and endocrine factors in women aged 35-39 (p=0.0004) and women aged ≥40 (p=0.0353). CONCLUSIONS: Systematic collection and analysis of big data in a south-south cooperation model allow regional growth by implementing evidence-based reproductive decisions.

Global fertility care with assisted reproductive technology.

Assisted reproductive technology has progressed greatly since the birth of Louise Brown in 1978. The pregnancy rates have increased, care is safer with significantly reduced multiple pregnancy and complication rates, infants have good health, and millions of people have been able to have the families they desired. The major challenges facing assisted reproductive technology are to continue to increase the quality of care, increase utilization through more societal funding, and expand care to nontraditional and marginalized populations in all countries, especially lower- and middle-income countries where access is currently limited. Significant collaboration among professionals, organizations, the World Health Organization, and policymakers is occurring and will be necessary to achieve these goals.

COVID-19-related uncertainty: fertility staff experiences of its sources, processing, responses, and consequences.

STUDY QUESTION: What are fertility staff experiences of managing COVID-19-related uncertainty after fertility clinics re-opened? SUMMARY ANSWER: Staff identified many COVID-19-related uncertainty sources, the main being the COVID-19 health threat, to which most clinics and staff responded effectively by implementing safety protocols and building strong collaborative environments that facilitated the acquisition and application of information to guide organizational responses during a rapidly changing situation, but with costs for staff and patients. WHAT IS KNOWN ALREADY: COVID-19 created significant disruption in fertility care delivery, including temporary clinic closure and treatment delay. Patients experienced significant distress, including concerns regarding the impact of COVID-19 and its vaccine on fertility and pregnancy. Multiple studies show that COVID-19-related uncertainty is a major threat and burden for healthcare staff, but this has not been investigated in reproductive medicine. STUDY DESIGN, SIZE, DURATION: A cross-sectional, online mixed-method bilingual (English, Spanish) survey (active 25 January-23 May 2021) was distributed to fertility staff across the UK, Latin America, and Africa. PARTICIPANTS/MATERIALS, SETTING, METHODS: Eligibility criteria were being a healthcare worker at a fertility clinic that had re-opened since its COVID-19-related closure, 18 years of age or older and ability to respond in English or Spanish. The survey was created in English, translated to Spanish, made available using Qualtrics, and consisted of four parts: (i) background and physical and mental wellbeing, (ii) open-ended questions regarding COVID-19 uncertainty, (iii) appraisal items regarding perceptions and impact of uncertainty, and (iv) changes in the workplace. The British Fertility Society and the African Network and Registry of Assisted Reproduction circulated the survey across the UK and Africa via email hyperlinks and social media platforms. The Argentinian Society of Reproductive Medicine and the Latin American Network of Assisted Reproduction distributed the survey across Latin America in the same manner. Thematic analysis was performed on responses from open-ended question to produce basic codes. Deductive coding grouped sub-themes across questions into themes related to the theory of uncertainty management. Descriptive statistics and repeated measures analysis of variance were used on the quantitative data. MAIN RESULTS AND THE ROLE OF CHANCE: In total, 382 staff consented to the survey, 107 did not complete (28% attrition), and 275 completed. Sixty-three percent were women, 69% were physicians, and 79% worked at private clinics. Thematic analysis produced 727 codes, organized in 92 sub-themes, and abstracted into 18 themes and one meta-theme reflecting that uncertainty is stressful but manageable. The types of uncertainties related to the threat of COVID-19 (20.6%), unpredictability of the future (19.5%), failure of communication (11.4%), and change in the workplace (8.4%). Staff appraisals of negative and positive impact of uncertainty were significantly lower (P < 0.001) than appraisals of stress, controllability, and having what it takes to cope with uncertainty. To process uncertainty, clinics focused on information dissemination (30.8%) and building a collaborative work environment (5.8%), while staff employed proactive coping (41.8%) and emotional and cognitive processing (9.6%). Main organizational responses consisted on work restructuring (41.3%, e.g. safety protocols), adapting to adversity (9.5%, e.g. supplies, preparation), and welfare support (13.8%), though staff perceived lack of support (17.5%). Negative consequences of uncertainty were worse self- and patient welfare (12.1%) and worse communication due to virtual medicine and use of mask (9.6%). Positive consequences were work improvements (8.3%), organizational adaptation (8.3%), improved relationships (5.6%), and individual adaptation (3.2%). Ninety-two percent of participants thought changes experienced in the workplace due to COVID-19 were negative, 9.1% nor negative nor positive, and 14.9% positive. Most staff thought that their physical (92.4%) and mental health (89.5%) were good to excellent. LIMITATIONS, REASONS FOR CAUTION: Participants were self-selected, and most were physicians and embryologists working at private clinics based in Latin America. The study did not account for how variability in national and regional COVID-19 policy shaped staff experiences of uncertainty. WIDER IMPLICATIONS OF THE FINDINGS: To address COVID-19 uncertainty, clinics need to promote collaborative (clinic, staff, patients) processing of uncertainty, clear team coordination and communication, organizational flexibility, and provision of support to staff and patients, with an emphasis on cognitive coping to decrease threat of and increase tolerance to uncertainty. Uncertainty management interventions bespoke to fertility care that integrate these components may increase clinics resilience to COVID-19-related and other types of uncertainty.

Assisted reproductive technologies in Latin America: the Latin American Registry, 2019.

RESEARCH QUESTION: What was the utilization, effectiveness and safety of assisted reproductive technology (ART) in Latin America during 2019? DESIGN: This was a retrospective collection of multinational data on ART performed at 196 institutions from 15 countries. RESULTS: A total of 106,918 initiated cycles, 18,133 deliveries and 21,096 births were reported. ART utilization was 24-558 cycles per million inhabitants. Women aged ≥40 years represented 32.9% of fresh IVF and intracytoplasmic sperm injection (ICSI) cycles. After removing freeze-all cycles, the delivery rate per oocyte retrieval was 17.3% for ICSI and 19.5% for IVF. Overall, single-embryo transfer (SET) represented 36.2% of fresh transfers, with a 19.5% delivery rate per transfer, increasing to 30.7% for elective SET and 32.7% for blastocyst elective SET (eSET). The delivery rate for double-embryo transfers (DET) was 27.8%, increasing to 37.1% after elective DET. This 6.4% increment in deliveries between eSET and elective DET resulted in a 12-fold increase in twin births. Furthermore, overall perinatal mortality was more than two-fold higher for twin compared with singleton deliveries. The delivery rate for frozen-thawed SET reached 28.1%, most being blastocyst transfers. Of all births, 72.3% were singletons, 26.4% twins and 1.3% triplets and higher multiples. Preterm deliveries reached 14.3% for singletons and 58.1% for twins. Perinatal mortality was 7.4‰ in singletons, 17.2‰ for twins and 62.9‰ for triplets or higher. CONCLUSIONS: The number of initiated cycles has slowly increased in countries with laws or regulations facilitating access. FET cycles predominate and blastocyst SET are also increasing. The data show that, especially in young women and oocyte recipients, when there is more than one blastocyst for transfer, eSET should be the rule.

Celebrating 30 years of ART in Latin America; and the 2018 report.

OBJECTIVE: What are the trends in patient characteristics, effectiveness and safety of assisted reproductive technology (ART) performed in Latin America over the past three decades, as well as the detailed outcomes of procedures initiated in 2018?. DESIGN: Retrospective collection of multinational data including epidemiology and outcomes of ART performed between 1990 and 2018. RESULTS: Over these 30 years we report 955,117 initiated cycles, 191,191 deliveries and 238,045 live births. In 1990, 66.5% of women were ≤34 years and 8.7% ≥40 years; in 2018, 26.4% of women were ≤34 years and 32.0% were ≥40 years. In 1990, 60.4% of transfers included ≥3 embryos, falling to 13.5% in 2018, and single embryo transfer (SET) increased from 13.8% to 30.4% between 1990 and 2018. Delivery rate per fresh transfer increased from approximately 17% in the 1990s to 25% in 2018, with a meaningful drop in high-order multiples, from 5-9% in the 1990s to 0.4% in 2018. This drop is associated with increasing use of frozen embryo transfer (FET) (57% in 2018) compared with 10% in 2000. In 2018, delivery rate in FET was 28.3%, reaching 31.2% in freeze-all cycles; and the cumulative live birth rate (fresh + FET) was 41.9%. Elective SET also increased, from 0.9% in 2010 to 10% in 2018. The delivery rate in elective SET (31.7%) was only 5.4% lower than elective double embryo transfer (DET) (37.1%); however, multiple births increased from 2.1% to 25.5% twins and 0.4% triplets in elective DET. CONCLUSIONS: The Latin American Registry of Assisted Reproduction (RLA) celebrates 30 years of voluntary reporting from a total of nearly 200 centres in 15 countries. This South-South Cooperation network has proven to be an efficient and safe system for technological transfer and regional growth.

International Committee for Monitoring Assisted Reproductive Technologies world report: assisted reproductive technology, 2014†.

STUDY QUESTION: What were the utilization, effectiveness and safety of practices in assisted reproductive technologies (ART) globally in 2014 and what global trends could be observed? SUMMARY ANSWER: The estimated total number of ART cycles conducted in 76 participating countries in 2014 was 1.93 million representing ∼66% of global activity, with 5-year trends including an increase in success rates and proportion of frozen embryo transfer (FET) cycles, improvement in cumulative live birth rates per aspiration, a continued increase in single embryo transfer (SET) and thus a reduction in multiple birth rates, an increase in preimplantation genetic testing and stabilization in the use of intracytoplasmic sperm injection (ICSI). WHAT IS KNOWN ALREADY: ART is widely practiced throughout the world but continues to be characterized by significant disparities in utilization, practice, effectiveness and safety. The International Committee for Monitoring Assisted Reproductive Technologies (ICMART) annual world report series provides an important instrument for tracking trends in ART treatment and for providing clinical and public health data to ART professionals, health authorities, patients and the general public. STUDY DESIGN, SIZE, DURATION: A retrospective, cross-sectional survey on ART procedures performed globally during 2014 was carried out. A new method for calculating ART utilization rates and number of babies born was introduced in this latest ICMART world report. PARTICIPANTS/MATERIALS, SETTING, METHODS: Overall, 76 countries and 2 746 ART centres submitted data through national and regional ART registries on ART cycles performed during 2014 and their treatment and pregnancy outcomes. ART cycles and outcomes are described at a country level, regionally and globally. Aggregate country data are processed and analyzed based on methods developed by ICMART. MAIN RESULTS AND THE ROLE OF CHANCE: A total of 1 629 179 ART cycles were reported for the treatment year 2014. After imputing data for missing values and non-reporting centres in reporting countries, an estimated 1 929 905 cycles resulted in >439 039 babies in reporting countries. From 2010 to 2014, the number of reported non-donor aspirations and FET cycles increased by 37.3% and 67.5%, respectively. The proportion of women aged ≥40 years undergoing non-donor ART increased from 23.2% in 2010 to 27.0% in 2014. ICSI, as a percentage of non-donor aspiration cycles, remained relatively stable at 64.8%. The IVF/ICSI combined delivery rates per fresh aspiration and FET cycle were 19.9% and 24.3%, respectively. In fresh non-donor cycles, SET increased from 30.0% in 2010 to 40.0% in 2014, while the average number of transferred embryos decreased from 1.95 to 1.73-but with wide country variation. The rate of twin deliveries following fresh non-donor transfers continued to decrease, from 20.4% in 2010 to 16.2% in 2014, and the triplet rate decreased from 1.1% to 0.5%. In FET non-donor cycles in 2014, the SET rate was 61.6%, with an average of 1.43 embryos transferred, resulting in twin and triplet rates of 10.1% and 0.2%, respectively. The cumulative delivery rate per aspiration increased from 27.1% in 2010 to 32.1% in 2014. The overall perinatal mortality rate per 1 000 births was 19.4 following fresh IVF/ICSI cycles and 9.5 following FET cycles. Among reporting countries, oocyte donation cycles represented 7.3% of all embryo transfers (89 751 transfer cycles) and resulted in 39 278 babies. LIMITATIONS, REASONS FOR CAUTION: The data presented are dependent on the quality and completeness of data submitted by individual countries to ICMART directly or through regional registries. This report covers approximately two-thirds of world ART activity. China is a major contributor of global cycles missing from this report. Continued efforts to improve the quality and consistency of ART data reported by registries are still needed, including the use of internationally agreed standard definitions (The International Glossary of Infertility and Fertility Care). A new method was introduced in this report to calculate ART utilization and number of babies born following ART; therefore, these results are not directly comparable with previous reports. WIDER IMPLICATIONS OF THE FINDINGS: The ICMART world reports provide the most comprehensive global statistical census and review of ART utilization, effectiveness, safety and quality. While ART treatment effectiveness and safety continue to increase globally, the wide disparities in access to treatment, procedures performed and embryo transfer practices warrant attention by clinicians and policymakers. The new method for estimating ART utilization and number of babies born provided more conservative estimates compared to the previuos method.

Delivery rate per fresh transfer increased from approximately 17% in the 1990s to 25% in 2018, with a meaningful drop in high-order multiples, from 5-9% in the 1990s to 0.4% in 2018. This drop is associated with increasing use of frozen embryo transfer (FET) (57% in 2018) compared with 10% in 2000. In 2018, delivery rate in FET was 28.3%, reaching 31.2% in freeze-all cycles; and the cumulative live birth rate (fresh + FET) was 41.9%. Elective SET also increased, from 0.9% in 2010 to 10% in 2018. The delivery rate in elective SET (31.7%) was only 5.4% lower than elective double embryo transfer (DET) (37.1%); however, multiple births increased from 2.1% to 25.5% twins and 0.4% triplets in elective DET. CONCLUSION: The Latin American Registry of Assisted Reproduction (RLA) celebrates 30 years of voluntary reporting from a total of nearly 200 centres in 15 countries. This South-South Cooperation network has proven to be an efficient and safe system for technological transfer and regional growth.

International Committee for Monitoring Assisted Reproductive Technologies (ICMART): world report on assisted reproductive technologies, 2013.

OBJECTIVE: To report the utilization, effectiveness, and safety of practices in assisted reproductive technology (ART) globally in 2013 and assess global trends over time. DESIGN: Retrospective, cross-sectional survey on the utilization, effectiveness, and safety of ART procedures performed globally during 2013. SETTING: Seventy-five countries and 2,639 ART clinics. PATIENT(S): Women and men undergoing ART procedures. INTERVENTION(S): All ART. MAIN OUTCOME MEASURE(S): The ART cycles and outcomes on country-by-country, regional, and global levels. Aggregate country data were processed and analyzed based on methods developed by the International Committee for Monitoring Assisted Reproductive Technology (ICMART). RESULT(S): A total of 1,858,500 ART cycles were conducted for the treatment year 2013 across 2,639 clinics in 75 participating countries with a global participation rate of 73.6%. Reported and estimated data suggest 1,160,474 embryo transfers (ETs) were performed resulting in >344,317 babies. From 2012 to 2013, the number of reported aspiration and frozen ET cycles increased by 3% and 16.4%, respectively. The proportion of women aged >40 years undergoing nondonor ART increased from 25.2% in 2012 to 26.3% in 2013. As a percentage of nondonor aspiration cycles, intracytoplasmic sperm injection (ICSI) was similar to results for 2012. The in vitro fertilization (IVF)/ICSI combined delivery rates per fresh aspiration and frozen ET cycles were 24.2% and 22.8%, respectively. In fresh nondonor cycles, single ET increased from 33.7% in 2012 to 36.5% in 2013, whereas the average number of transferred embryos was 1.81-again with wide country variation. The rate of twin deliveries after fresh nondonor transfers was 17.9%; the triplet rate was 0.7%. In frozen ET cycles performed in 2013, single ET was used in 57.6%, with an average of 1.49 embryos transferred and twin and triplet rates of 10.8% and 0.4%, respectively. The cumulative delivery rate per aspiration was 30.4%, similar to that in 2012. Perinatal mortality rate per 1,000 births was 22.2% after fresh IVF/ICSI and 16.8% after frozen ET. The data presented depended on the quality and completeness of the data submitted by individual countries. This report covers approximately two-thirds of world ART activity. Continued efforts to improve the quality and consistency of reporting ART data by registries are still needed. CONCLUSION(S): Reported ART cycles, effectiveness, and safety increased between 2012 and 2013 with adoption of a better method for estimating unreported cycles.

International Committee for Monitoring Assisted Reproductive Technologies world report: assisted reproductive technology 2012†.

STUDY QUESTION: What was the utilization, effectiveness and safety of practices in ART globally in 2012 and what global trends could be observed? SUMMARY ANSWER: The total number of ART cycles increased by almost 20% since 2011 and the main trends were an increase in frozen embryo transfers (FET), oocyte donation, preimplantation genetic testing and single embryo transfers (SET), whereas pregnancy and delivery rates (PR, DR) remained stable, and multiple deliveries decreased. WHAT IS KNOWN ALREADY: ART is widely practiced throughout the world, but continues to be characterized by significant disparities in utilization, availability, practice, effectiveness and safety. The International Committee for Monitoring Assisted Reproductive Technologies (ICMART) annual world report provides a major tool for tracking trends in ART treatment for over 25 years and gives important data to ART professionals, public health authorities, patients and the general public. STUDY DESIGN, SIZE, DURATION: A retrospective, cross-sectional survey on the utilization, effectiveness and safety of ART procedures performed globally during 2012 was carried out. PARTICIPANTS/MATERIALS, SETTING, METHODS: Sixty-nine countries and 2600 ART clinics submitted data on ART cycles performed during the year 2012, and their pregnancy outcome, through national and regional ART registries. ART cycles and outcomes are described at country, regional and global levels. Aggregate country data were processed and analyzed based on methods developed by ICMART. MAIN RESULTS AND ROLE OF CHANCE: A total of 1 149 817 ART cycles were reported for the treatment year 2012. After imputing data for missing values and non-reporting clinics in reporting countries, 1 948 898 cycles (an increase of 18.6% from 2011) resulted in >465 286 babies (+17.9%) in reporting countries. China did not report and is not included in this estimate. The best estimate of global utilization including China is ∼2.8 million cycles and 0.9 million babies. From 2011 to 2012, the number of reported aspirations and FET cycles increased by 6.9% and 16.0%, respectively. The proportion of women aged 40 years or older undergoing non-donor ART increased from 24.0% in 2011 to 25.2% in 2012. ICSI, as a percentage of non-donor aspiration cycles, increased from 66.5% in 2011 to 68.9% in 2012. The IVF/ICSI combined delivery rates per fresh aspiration and FET cycles were 19.8% and 22.1%, respectively. In fresh non-donor cycles, SET increased from 31.4% in 2011 to 33.7% in 2012, while the average number of transferred embryos decreased from 1.91 to 1.88, respectively-but with wide country variation. The rates of twin deliveries following fresh non-donor transfers decreased from 19.6% in 2011 to 18.0% in 2012, and the triplet rate decreased from 0.9% to 0.8%. In FET non-donor cycles, SET was 54.8%, with an average of 1.54 embryos transferred and twin and triplet rates of 11.1% and 0.4%, respectively. The cumulative DR per aspiration increased from 28.0% in 2011 to 28.9% in 2012. The overall perinatal mortality rate per 1000 births was 21.4 following fresh IVF/ICSI and 15.9 per 1000 following FET. LIMITATIONS, REASONS FOR CAUTION: The data presented depend on the quality and completeness of data submitted by individual countries to ICMART directly or through regional registries. This report covers approximately two-thirds of` world ART activity, with a major missing country, China. Continued efforts to improve the quality and consistency of reporting ART data by registries are still needed, including the use of internationally agreed standard definitions (International Glossary of Infertility and Fertility Care). WIDER IMPLICATIONS OF THE FINDINGS: The ICMART world reports provide the most comprehensive global statistical census and review of ART utilization, effectiveness, safety and quality. While ART treatment continues to increase globally, the wide disparities in access to treatment, procedures performed and embryo transfer practices warrant attention by clinicians and policy makers. With the increasing practice of SET and of freeze all and resulting increased proportion of FET cycles, it is clear that PR and DR per aspiration in fresh cycles do not give an overall accurate estimation of ART efficiency. It is time to use cumulative live birth rate per aspiration, combining the outcomes of FET cycles with the associated fresh cycle from which the embryos were obtained, and to obtain global consensus on this approach.
