Abstract
BACKGROUND Children conceived with assisted reproductive technologies (ART) or after a long waiting time have a higher prevalence of congenital malformations, but few studies have examined the contribution of type of infertility. OBJECTIVES To quantify the association between causes of infertility and prevalence of malformations. METHODS We compared the prevalence at birth of all and severe malformations diagnosed up to age 2 between 6656 children born in 1996-2017 to parents who had previously been assessed for infertility a an academic fertility clinic ("exposed") and 10,382 children born in the same period to parents with no recent medical history of infertility ("reference"). We estimated prevalence ratios (PR) and prevalence differences (PD), by infertility status, type of treatment (non-ART, ART), and infertility diagnosis, in all children and among singletons. RESULTS Compared with children of parents with no infertility, children of parents with infertility had a higher prevalence of malformations (both definitions), particularly following ART conceptions. After accounting for treatment, ovulatory disorders were associated with a higher prevalence of both all (PR 1.49, 95% confidence interval (CI) 1.15, 1.93; PD 3.8, 95% CI 1.0, 6.6) and severe (PR 1.53, 95% CI 1.02, 2.29; PD 1.8, 95% CI -0.2, 3.7) malformations (the estimates refer to exposed children conceived without treatment). Unexplained and male factor infertility were associated with all and severe malformations, respectively. Estimates among singletons were similar. A diagnosis of ovulatory disorders was associated with all malformations also in analyses restricted to exposed children, regardless of treatment (we did not examine severe malformations, due to limited power). CONCLUSIONS In this study, ovulatory disorders were consistently associated with a higher prevalence of congenital malformations (including severe malformations) among live births, regardless of mode of conception.

Abstract
RESEARCH QUESTION Are the demographics and clinical outcomes similar for patients aged ≥40 but <43 years seeking IVF in Ontario, Canada, before and after implementation of the Ontario Fertility Program (OFP), which supports public funding of IVF up to age 43? DESIGN Retrospective database review using the Canadian Assisted Reproductive Technologies Registry Plus (CARTR Plus) and Better Outcomes Registry & Network (BORN) Ontario databases. Cycles from women who underwent autologous IVF and who were aged ≥40 and <43 years were analysed during a 2-year period prior to (2014-2015) and after (2016-2017) introduction of publicly funded IVF through the OFP. RESULTS There was an almost doubling of treatment cycles in women aged 40-42 in Ontario after the OFP launch. Clinical pregnancy rate per cycle start (17.0% versus 13.3%, P < 0.001) and cumulative clinical pregnancy rate per stimulation cycle (20.5% versus 16.8%, P < 0.001) were statistically higher in women before OFP implementation. While cumulative live birth rate per cycle start was statistically lower after funding was introduced (12.5% versus 10.5%, P = 0.027), the clinical importance of this difference appears small. Outcomes were above the 10% live birth per cycle threshold recommended by the Advisory Process for Infertility Services panel, commissioned by the Ministry of Health, to determine access to publicly funded IVF. CONCLUSIONS Use of IVF in women over age 40 doubled with access to OFP funding; however, eligibility criteria based on age still meet the target of achieving a cumulative live birth rate of at least 10%.

Abstract
STUDY QUESTION Do publicly funded fertility treatment and single embryo transfer (SET) result in lower hospitalization rates of children of parents with infertility? SUMMARY ANSWER Following the 2010 Quebec law introducing free fertility treatment and SET, neonatal intensive care unit (NICU) admissions decreased among all children born to parents with infertility, but not among singletons, whose risk remained slightly higher than that of children of parents without infertility, even accounting for treatment and maternal age. WHAT IS KNOWN ALREADY Previous studies reported lower NICU admission rates among children conceived with ART after the 2010 law; however, children conceived without ART by parents with infertility were not considered. STUDY DESIGN, SIZE, DURATION Cohort study of children born in 1997-2017 to patients evaluated for infertility ('exposed') at an academic fertility center in Montreal (Canada) in 1996-2015. A random sample of births to Montreal residents served as comparison. Outcomes were identified from Quebec administrative databases. PARTICIPANTS/MATERIALS, SETTING, METHODS We compared children's healthcare utilization before and after the 2010 law in 6273 exposed and 12 583 randomly sampled births (6846 and 12 775 children, respectively). We repeated the analysis among children conceived in the 63 months before and after the law ('restricted period'), and examined whether differences in twinning, fertility treatment, and maternal age explained the higher risk of NICU admission among children of parents with infertility. MAIN RESULTS AND THE ROLE OF CHANCE In the exposed cohort, the proportion of twin births and of several adverse outcomes declined after the law. NICU admission and duration of NICU stay decreased overall, but not in singletons. Both measures remained higher in exposed children. Except for NICU admission, hospitalization rates were similar in exposed and random sample children. After accounting for fertility treatment and maternal age, exposed singletons were 17% more likely to be admitted to the NICU than children of parents with no medical history of infertility. LIMITATIONS, REASONS FOR CAUTION Sample size was relatively small; infertile patients were from a single center and the random sample from one city. Despite some limitations, administrative databases are likely to accurately reflect healthcare utilization. WIDER IMPLICATIONS OF THE FINDINGS Universal access to treatment and, particularly, SET results in an overall reduction of adverse outcomes among children conceived with treatment; however, children of parents with infertility are at a slightly higher risk, regardless of treatment. STUDY FUNDING/COMPETING INTEREST(S) This study was funded by the Canadian Institutes for Health Research (CIHR, grant no. 123362). No competing interests. TRIAL REGISTRATION NUMBER N/A.

Abstract
STUDY QUESTION Does publicly funded assisted reproductive technology result in improved maternal and infant outcomes? SUMMARY ANSWER Publicly funded ART in Quebec was associated with reduced risks of preeclampsia, cesarean delivery, preterm birth, low birth weight and other adverse outcomes. WHAT IS KNOWN ALREADY Publicly funded ART programs that provide free access to single embryo transfer are known to decrease the rate of multiple pregnancy, but the impact on other pregnancy outcomes is unknown. STUDY DESIGN, SIZE, DURATION We conducted a pre- and post-comparison study of 597 416 pregnancies conceived between July 2008 and September 2015 in Quebec, Canada, a region where public funding of ART began in August 2010. PARTICIPANTS/MATERIALS, SETTING, METHODS We included all pregnant women who conceived by ART (n = 14 309) or spontaneously (n = 583 107) and delivered a live or stillborn infant in hospitals of Quebec. The main exposure measure was conception before versus during the publicly funded ART program. Outcomes included measures of maternal and infant morbidity and mortality. We estimated risk ratios (RR) and 95% confidence intervals for the association of publicly funded ART with maternal and infant outcomes using log-binomial regression models adjusted for maternal characteristics. MAIN RESULTS AND THE ROLE OF CHANCE In this study, 2638 pregnancies were conceived by ART before, and 11 671 were conceived by ART, during public funding. Compared with no public funding, ART funding was associated with reduced risks of severe maternal morbidity (RR 0.64, 95% CI 0.50-0.83), preeclampsia (RR 0.55, 95% CI 0.44-0.68), cesarean delivery (RR 0.83, 95% CI 0.77-0.89), preterm birth (RR 0.67, 95% CI 0.60-0.75), low birth weight (RR 0.63, 95% CI 0.55-0.72), severe neonatal morbidity (RR 0.75, 95% CI 0.57-0.99) and neonatal intensive care unit admission (RR 0.65, 95% CI 0.53-0.78). When multiple pregnancies were excluded, ART funding continued to be associated with a lower risk of preeclampsia (RR 0.61, 95% CI 0.48-0.79) and preterm birth (RR 0.85, 95% CI 0.73-0.99). However, ART funding was associated with increased risk of gestational diabetes. LIMITATIONS, REASONS FOR CAUTION We had no information on the type of ART, number of in-vitro fertilization cycles or number of embryos transferred. We lacked data on body mass index, ethnicity and smoking and cannot rule out residual confounding. WIDER IMPLICATION OF THE FINDINGS Our findings suggest that publicly funded ART programs that encourage single embryo transfer may have substantial benefits for a range of maternal and infant outcomes, beyond prevention of multiple births.

Fertil Steril 2021; 114:715-721.

Abstract
The health of children born through assisted reproductive technologies (ART) is particularly vulnerable to policy decisions and market forces that play out before they are even conceived. ART treatment is costly, and public and third-party funding varies significantly between and within countries, leading to considerable variation in consumer affordability globally. These relative cost differences affect not only who can afford to access ART treatment, but also how ART is practiced in terms of embryo transfer practices, with less affordable treatment creating a financial incentive to transfer more than one embryo to maximize the pregnancy rates in fewer cycles. One mechanism for reducing the burden of excessive multiple pregnancies is to link insurance coverage to the number of embryos that can be transferred; another is to combine supportive funding with patient and clinician education and public reporting that emphasizes a "complete" ART cycle (all embryo transfers associated with an egg retrieval) and penalizes multiple embryo transfers. Improving funding for fertility services in a way that respects clinician and patient autonomy and allows patients to undertake a sufficient number of cycles to minimize moral hazard improves outcomes for mothers and babies while reducing the long-term economic burden associated with fertility treatments.

Abstract
AbstractA belief exists that transferring multiple embryos can improve pregnancy rates. However, this concept is flawed. Multiple factors affect outcomes when transferring embryos, endometrial receptivity, and rates of aneuploidy among them. In this article, we will discuss how factors can affect outcomes at IVF that are independent of the number of embryos transferred. It is important to understand the role of accessory factors on pregnancy rates to be able to counsel patients as per the number of embryos that should be transferred. An understanding of this concept will also lead to a realistic understanding of how multiple embryo transfers may result in better cumulative pregnancy rates than a single transfer of multiple embryos. Finally, we will present a SWOT analysis diagram to help guide clinical decision-making.

Abstract
BACKGROUND The purpose of this study was to assess whether the outcomes from IVF-preimplantation genetic testing (IVF-PGT) cycles for single gene defects (SGD) (PGT-M) differ between a privately funded period (PRP) and publicly funded period (PUP). METHODS A retrospective cohort study was conducted in a North-American single tertiary center. The PRP (March 1998 to July 2010) comprised 56 PGT-M cycles from 58 IVF cycles in 38 couples, and the PUP (August 2010 to May 2015) comprised 59 PGT-M cycles from 87 IVF cycles in 38 couples. One PGT-M cycle is defined as one biopsy procedure from one or serial IVF cycles. A p-value of 0.05 was considered statistically significant. RESULTS The clinical pregnancy rates (CPR) per PGT-M cycle were 30.4% and 52.5% in each period, respectively (p=0.021). The live birth rates (LBR) per PGT-M cycle were 21.5% versus 40.9% in each period, respectively (p=0.037). A sub-analysis within the PUP comparing 39 PGT-M cycles from 39 IVF cycles with 20 PGT-M cycles from 49 IVF cycles yielded CPRs per PGT-M cycle of 64.1% and 30.0% and LBRs per PGT-M cycle of 53.8% and 15.0%, in each group, respectively (p< 0.05 for both). CONCLUSION The transition from private to public funding and a single embryo transfer (ET) guideline has little impact on embryological and clinical outcomes of PGT-M cycles, and results in lower rates of multiple pregnancies. However, these two systems may serve different populations.

Abstract
In recent years, the prevalence of infertility has increased due to delayed childbearing and an increase in the rate of male infertility. Given the high cost of fertility treatment, this option is not valid for families with a low income, and those who can afford it usually choose to have multiple embryo transfer, which has led to an increase in multiple birth rates and an increase in the cost of perinatal care. Due to the expected increase in infertility and decrease in the national live birth rate, the US should set a plan to fund infertility treatment and lead a policy for single embryo transfer. This will offset the decrease in the national birth rates and decrease expenditure on perinatal and neonatal complications resulting from multiple births.

Abstract
OBJECTIVE(S) The aim of this study was to compare the patient characteristics, type of genetic disease and inheritance, volume of activity, practice patterns and pregnancy outcomes, in private versus publically funded IVF pre-implantation genetic testing (PGT) for translocation (IVF-PGT-SR) and aneuploidy (PGT-A) periods. STUDY DESIGN This study retrospectively analyzed data during both privately funded period (PRP) and publically funded period (PUP) of assisted reproductive technology (ART) for a total of 275 patients. 83 patients underwent IVF-PGT-SR and 192 patients underwent IVF-PGT-A. Given that PGT-SR is a chromosomal abnormality hereditary in nature, whereas PGT-A is sporadic in addition to the contrasting funding policies, the two cohorts were analyzed separately. To achieve the proposed objective, the two groups under analysis were grouped in accordance with their respective coverage systems for infertility. RESULTS Among translocation patients, 94 normal/balanced embryos were obtained from 47 IVF-PGT cycles in PRP whereas 145 embryos were obtained from 92 IVF-PGT cycles in PUP. The average number of embryos transferred per embryo transfer cycle was significantly lower in PUP in comparison to PRP (1.13 vs. 1.74, p < 0.0001). 13 singletons and 2 sets of twins were conceived in PRP. 14 singletons were conceived in PUP. Regardless of funding period, there were more reciprocal translocation carriers (79.4% in PRP and 76.4% in PUP) and more male carriers (82.4% in PRP and 60% in PUP), of which the majority had abnormal sperm parameters. Among aneuploidy patients, on average 2.5 embryos in PRP and 1.4 embryos in PUP were transferred per ET cycle (p = 0.05). There was a 13.3% increase in number of IVF-PGT-A attempts per patient in PRP compared to PUP. Live birth rate per IVF-PGT-A was higher in PRP (29.7% vs. 15%, P = 0.02), which consisted of 48 singletons and 18 multiparous pregnancies in PRP and 9 singletons in PUP. CONCLUSION(S) Public coverage of ART is associated with a greater utilization ART, as well as a reduced number in embryo transfer (ET) per cycle, a lower proportion of cycles resulting in successful pregnancy and a lower multiple birth rate. Our study ultimately shines light on the effect of providers' and patients' monetary conscious on pregnancy outcome.

Abstract
PURPOSE Although the clinical value of time-lapse imaging (TLI) systems in in vitro fertilization (IVF) cycles is still debated, its prevalence worldwide seems to be expanding. The situation of TLI in the USA has been recently surveyed, but these results might not be transposable to other countries with different IVF regulation and funding such as France. This study evaluated the TLI situation in French IVF laboratories. METHODS An anonymous online cross-sectional survey was sent by email to 210 embryologists in September and October 2017. Laboratories, demographics, TLI clinical use, purchasing plan, and embryologists' opinions were analyzed using logistic regression to calculate odds ratio. RESULTS Of the 210 lab directors surveyed, 78 responded (37.1%), 43 (55%) working in private IVF laboratories and 35 (45%) in public hospitals. Thirty (38.5%) were TLI users. The odds of TLI possession were not statistically different according to laboratory sector or size. Most embryologists (n = 21, 70%) used TLI for unselected patients. Cost was the main reason given by non-users for not implementing TLI (n = 24, 50%). Most respondents were convinced that TLI is superior to standard morphology (n = 52, 73.2%) and that TLI improves culture conditions (n = 62, 84.9%). However, half (n = 39, 54.9%) indicated that evidence was still lacking to assert TLI clinical usefulness. CONCLUSION The prevalence of TLI systems and embryologists' opinion in France was slightly different from the American situation. The different regulation and funding policy might account for some differences in terms of TLI use and perception.

Abstract
Background The transfer of multiple embryos after in vitro fertilization (IVF) increases the risk of twins and higher-order births. Multiple births are associated with significant health risks and maternal and neonatal complications, as well as physical, emotional, and financial stresses that can strain families and increase the incidence of depression and anxiety disorders in parents. Elective single embryo transfer (eSET) is among the most effective methods to reduce the risk of multiple births with IVF. Main body Current societal guidelines recommend eSET for patients <35 years of age with a good prognosis, yet even this approach is not widely applied. Many patients and clinicians have been reluctant to adopt eSET due to studies reporting higher live birth rates with the transfer of two or more embryos rather than eSET. Additional barriers to eSET include risk of treatment dropout after embryo transfer failure, patient preference for twins, a lack of knowledge about the risks and complications associated with multiple births, and the high costs of multiple IVF cycles. This review provides a comprehensive summary of strategies to increase the rate of eSET, including personalized counseling, access to educational information regarding the risks of multiple pregnancies and births, financial incentives, and tools to help predict the chances of IVF success. The use of comprehensive chromosomal screening to improve embryo selection has been shown to improve eSET outcomes and may increase acceptance of eSET. Conclusions eSET is an effective method for reducing multiple pregnancies resulting from IVF. Although several factors may impede the adoption of eSET, there are a number of strategies and tools that may encourage the more widespread adoption of eSET in clinical practice.
