Abstract
In the last four decades, advances in assisted reproductive technology (ART) have offered hope to individuals with fertility problems to conceive. However, a closer examination of the clinical outcomes of ART shows a stark contrast in Asian women compared to Caucasians, with majority of studies reporting lower reproductive success among Asian women. We performed a systematic review to elucidate the genes associated with ART clinical outcomes, with a focus on Asian ethnicities. We completed a database search to identify all studies associated with reproductive outcomes in women of different ethnic backgrounds. Following PRISMA, 128 studies were analyzed. Pathway analysis of gene sets was done using Cytoscapev3.4.0. We observed that age at menarche (AAM) was correlated with the timing of the first pregnancy, with Hawaiians having the lowest age (22.2 years) and Japanese the highest age (25.0 years). LIN28 mutations were associated with AAM and prevalent in both Chinese and American populations. FMR1 was most associated with ovarian reserve. Network analysis highlighted a close association between FMR1, FSHR, ESR1, BMP15, and INHA, through biological functions affecting menstrual cycle and hypothalamic-pituitary axis and therefore ovarian follicle development. Leveraging these findings, we propose the development of a personalized, ethnic-specific biomarker panel which would enhance patient stratification to address every woman's unique reproductive potential.

Am J Obstet Gynecol 2023; 228:557.e1-557.e10. [PMID: 36702210 PMCID: PMC11057011 DOI: 10.1016/j.ajog.2023.01.014] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2022] [Revised: 01/02/2023] [Accepted: 01/14/2023] [Indexed: 01/24/2023]
Abstract
BACKGROUND As the use of in vitro fertilization continues to increase in the United States, up-to-date models that estimate cumulative live birth rates after multiple oocyte retrievals and embryo transfers (fresh and frozen) are valuable for patients and clinicians weighing treatment options. OBJECTIVE This study aimed to develop models that generate predicted probabilities of live birth in individuals considering in vitro fertilization based on demographic and reproductive characteristics. STUDY DESIGN Our population-based cohort study used data from the National Assisted Reproductive Technology Surveillance System 2016 to 2018, including 196,916 women who underwent 207,766 autologous embryo transfer cycles and 25,831 women who underwent 36,909 donor oocyte transfer cycles. We used data on autologous in vitro fertilization cycles to develop models that estimate a patient's cumulative live birth rate after all embryo transfers (fresh and frozen) within 12 months after 1, 2, and 3 oocyte retrievals in new and returning patients. Among patients using donor oocytes, we estimated the cumulative live birth rate after their first, second, and third embryo transfers. Multinomial logistic regression models adjusted for age, prepregnancy body mass index (imputed for 18% of missing values), parity, gravidity, and infertility diagnoses were used to estimate the cumulative live birth rate. RESULTS Among new and returning patients undergoing autologous in vitro fertilization, female age had the strongest association with cumulative live birth rate. Other factors associated with higher cumulative live birth rates were lower body mass index and parity or gravidity ≥1, although results were inconsistent. Infertility diagnoses of diminished ovarian reserve, uterine factor, and other reasons were associated with a lower cumulative live birth rate, whereas male factor, tubal factor, ovulatory disorders, and unexplained infertility were associated with a higher cumulative live birth rate. Based on our models, a new patient who is 35 years old, with a body mass index of 25 kg/m2, no previous pregnancy, and unexplained infertility diagnoses, has a 48%, 69%, and 80% cumulative live birth rate after the first, second, and third oocyte retrieval, respectively. Cumulative live birth rates are 29%, 48%, and 62%, respectively, if the patient had diminished ovarian reserve, and 25%, 41%, and 52%, respectively, if the patient was 40 years old (with unexplained infertility). Very few recipient characteristics were associated with cumulative live birth rate in donor oocyte patients. CONCLUSION Our models provided estimates of cumulative live birth rate based on demographic and reproductive characteristics to help inform patients and providers of a woman's probability of success after in vitro fertilization.

Abstract
IMPORTANCE Multiple gestation is one of the biggest risks after in vitro fertilization (IVF), largely due to multiple embryo transfer (MET). Single embryo transfer (SET) uptake has increased over time and has been attributed to various factors, such as mandated insurance coverage for IVF and preimplantation genetic testing for aneuploidy (PGT-A). OBJECTIVE To investigate whether mandates for IVF insurance coverage are associated with decreased use of MET after PGT-A. DESIGN, SETTING, AND PARTICIPANTS This cohort study was conducted using data on embryo transfers reported to the Society for Assisted Reproductive Technology between 2014 and 2016. Data were analyzed from January to October 2021. EXPOSURES State-mandated coverage for fertility treatment and type of cycle transfer performed (PGT-A, untested fresh, and untested frozen). MAIN OUTCOMES AND MEASURES Use of MET compared with SET, live birth, and live birth of multiples. RESULTS There were 110 843 embryo transfers (mean [SD] patient age, 34.0 [4.5] years; 5520 individuals identified as African American [5.0%], 10 035 as Asian [9.0%], 5425 as Hispanic [4.9%], 45 561 as White [41.1%], and 44 302 as other or unknown race or ethnicity [40.0%]); 17 650 transfers used embryos that underwent PGT-A. Overall, among transferred embryos that had PGT-A, there were 9712 live births (55.0%). The odds of live birth were 70% higher with MET vs SET after frozen embryo transfer with PGT-A (OR, 1.70; 95% CI, 1.61-1.78), but the risk of multiples was 5 times higher (OR, 5.33; 95% CI, 5.22-5.44). The odds of MET in cycles with PGT-A in states with insurance mandates were 24% lower than in states without mandates (OR, 0.76; 95% CI, 0.68-0.85). CONCLUSIONS AND RELEVANCE This study found that despite the promise of using SET with PGT-A, MET after PGT-A was not uncommon. This practice was more common in states without insurance mandates and was associated with a high risk of multiples.

Abstract
This review appraises evidence on the difference between single- and double-embryo transfer (SET, DET) in assisted reproductive technology (ART) regarding the four healthcare quality dimensions most important to fertility patients and doctors. Regarding safety, not only does DET create the uncontested perinatal risks of twin pregnancies, but compelling evidence has added that singleton pregnancies after a vanishing twin also have poorer perinatal outcomes. SET is as effective as DET, as shown by meta-analyses of randomized controlled trials, comparing two cycles of SET versus DET and shown by cumulative live birth rates of entire ART trajectories of up to six cycles. Proposing SET, which is safer than DET and as effective, as the gold standard is not irreconcilable with patient-centred care if patients are thoroughly informed on the reasoning behind the proposition and welcomed to challenge whether it fits their personal values. The cost-efficiency of SET is clearly higher, which has even induced certain countries to start reimbursing ART on the condition that SET is used. In conclusion, SET should be the gold standard offered to all patients. The question is not whether to apply SET but how to apply it in terms of patient selection, patient-centred counselling and coverage of treatment.

Abstract
The American Society for Reproductive Medicine estimates that fewer than a quarter of infertile couples have sufficient access to infertility care. Insurers in the United States (US) have long considered infertility to be a socially constructed condition, and thus in-vitro fertilization (IVF) an elective intervention. As a result, IVF is cost prohibitive for many patients in the US. State infertility insurance mandates are a crucial mechanism for expanding access to fertility care in the US in the absence of federal legislation. The first state insurance mandate for third party coverage of infertility services was passed by West Virginia in 1977, and Maryland passed the country's first IVF mandate in 1985. To date, twenty states have passed legislation requiring insurers to cover or offer coverage for the diagnosis and treatment of infertility. Ten states currently have "comprehensive" IVF mandates, meaning they require third party coverage for IVF with minimal restrictions to patient eligibility, exemptions, and lifetime limits. Several studies analyzing the impact of infertility and IVF mandates have been published in the past 20 years. In this review, we characterize and contextualize the existing evidence of the impact of state insurance mandates on access to infertility treatment, IVF practice patterns, and reproductive outcomes. Furthermore, we summarize the arguments in favor of insurance coverage for infertility care and assess the limitations of state insurance mandates as a strategy for increasing access to infertility treatment. State mandates play a key role in the promotion of evidence-based practices and represent an essential and impactful strategy for the advancement of gender equality and reproductive rights.

Abstract
It is more than thirty years that perinatologists and healthcare personnel aim to reduce the morbidity associated with multiple pregnancy. In many cases, these complications stem from pregnancies achieved through artificial reproductive technologies (ART). Although dramatic measures have been taken to control those risks by increasing the proportion of single embryo transfers, the multiple pregnancy rate still remains relatively high among patient conceived through ART, carrying risks to both mothers and newborns, and is coupled with the related economic burden associated with prematurity. The aim of this review is to provide the current evidence regarding single embryo transfer to assist decision-makers and to promote patient knowledge toward an elective policy to reduce the risk of twinning. Single embryo transfer may aid in the further reduction of multiple pregnancy and, in most cases, will maintain patient autonomy and right of choice.

Abstract
The practice of in vitro fertilization has changed tremendously since the birth of the first in vitro fertilization infant in 1978. With the success of early in vitro fertilization programs in the United States, there was a substantial rise in twin births nationwide. In the mid-1990s, more than 30% of in vitro fertilization cycles resulted in twin or higher-order multifetal pregnancies. Since that time, we not only have witnessed improvements in laboratory and treatment efficacy but also have seen a dramatic impact on pregnancy outcomes, specifically regarding twin pregnancies. Because the field evolved and the risks of multifetal pregnancies became more salient, in 2019, the rate of twin pregnancies had dropped to <7% of cycles. This improvement was largely because of technical advancements and revised professional guidance: culturing embryos longer before transfer, improved freezing technology, embryo preimplantation genetic testing, and revised professional guidance regarding the number of embryos to transfer. These developments have led to single-embryo transfer becoming the standard of care in most scenarios. We used national in vitro fertilization surveillance data of all autologous in vitro fertilization cycles from 1996 to 2019 to illustrate trends in the following improved outcomes: autologous embryo transfer cycles involving blastocyst-stage embryos, vitrified embryos, preimplantation genetic testing cycles, total number of embryos being transferred per cycle, and single-embryo transfer usage over time. Among deliveries from autologous embryo transfers, we highlighted trends in singleton births over time and proportion of deliveries involving twins, triplets, quadruplets, or greater. The notable progress in reducing the rate of multifetal pregnancies with in vitro fertilization was largely attributed to a series of technical and clinical actions, culminating in an 80% reduction in the incidence of multiple births without a loss in overall treatment effectiveness.

Abstract
OBJECTIVE To evaluate whether singleton live births achieved following in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) in women with late moderate-to-severe ovarian hyperstimulation syndrome (OHSS) is associated with adverse perinatal outcomes. METHODS This was a single-center retrospective cohort study conducted from January 2016 to June 2021. A total of 4,012 IVF/ICSI-fresh embryo transfer cycles that achieved singleton live births were included. According to the diagnosis of OHSS, the cycles were divided into two groups: late moderate-to-severe OHSS (MS-OHSS) group (n = 114) and non-OHSS group (n = 3,898). Multiple baseline covariates were controlled by propensity score matching, yielding 114 late MS-OHSS singleton live births matched to 337 non-OHSS singleton live births. The primary outcome of the study was normal term infant. The secondary outcomes were perinatal complications, gestational age at birth, birth weight, and birth height. RESULTS Before propensity score matching, no significant difference in perinatal outcomes was identified between late MS-OHSS group and non-OHSS group. After matching maternal age, BMI, basal serum FSH level, basal serum AMH level, basal antral follicle count, type of stimulation protocol, day of embryo development for embryo transfer, number of embryo transfer, and number of oocytes retrieved, there was still no significant difference in obstetric outcomes and neonatal outcomes between the two groups. CONCLUSIONS The findings demonstrate that the perinatal outcomes were similar between the two groups. However, because the sample size of patients with late MS-OHSS was limited in this study, further investigations are warranted using a larger sample size.

Abstract
STUDY QUESTION For donor oocyte recipients, are birth outcomes superior for fresh versus frozen embryos? SUMMARY ANSWER Among fresh donor oocyte recipients, fresh embryos are associated with better birth outcomes when compared with frozen embryos. WHAT IS KNOWN ALREADY Frozen embryo transfer (ET) with vitrification has been associated with improved pregnancy rates, but also increased rates of large for gestational age infants. Donor oocyte recipients represent an attractive biological model to attempt to isolate the impact of embryo cryopreservation on IVF outcomes, yet there is a paucity of studies in this population. STUDY DESIGN, SIZE, DURATION A retrospective cohort of the US national registry, the Society for Assisted Reproductive Technology Clinic Outcome Reporting System, of IVF cycles of women using fresh donor oocytes resulting in ET between 2013 and 2015. Thawed oocytes were excluded. PARTICIPANTS/MATERIALS, SETTINGS, METHODS Good obstetric outcome (GBO), defined as a singleton, term, live birth with appropriate for gestational age birth weight, was the primary outcome measure. Secondary outcomes included live birth, clinical pregnancy, spontaneous abortion, preterm birth, multiple births and gestational age-adjusted weight. Outcomes were modeled using the generalized estimating equation approach. MAIN RESULTS AND THE ROLE OF CHANCE Data are from 25 387 donor oocyte cycles, in which 14 289 were fresh and 11 098 were frozen ETs. A GBO was 27% more likely in fresh ETs (26.3%) compared to frozen (20.9%) (adjusted risk ratio 1.27; 95% confidence interval (CI) 1.21-1.35; P < 0.001). Overall, fresh transfer was more likely to result in a live birth (55.7% versus 39.5%; adjusted risk ratio 1.21; 95% CI 1.18-1.26; P < 0.001). Among singleton births, there was no difference in gestational age-adjusted birth weight between groups. LIMITATION, REASONS FOR CAUTION Our cohort findings contrast with data from autologous oocytes. Prospective studies with this population are warranted. WIDER IMPLICATIONS OF THE FINDINGS Among donor oocyte recipients, fresh ETs may be associated with better birth outcomes. Reassuringly, given its prevalent use, modern embryo cryopreservation does not appear to result in phenotypically larger infants. STUDY FUNDING/COMPETING INTEREST(S) None. TRIAL REGISTRATION NUMBER N/A.

Abstract
PURPOSE To evaluate if preimplantation genetic testing (PGT) improves the odds of a healthy live birth amongst recipients of fresh donor oocytes. METHODS We performed a retrospective cohort study including in vitro fertilization cycles of women using fresh donor oocytes reported to the Society for Assisted Reproductive Technology Clinic Outcome Reporting System, between 2013 and 2015. Cycles were categorized based on PGT. Primary outcome measure was a good birth outcome (GBO), defined as a singleton, term, live birth with an average birthweight. Multivariable generalized estimating equation models were fit to analyze the effect of PGT. Interaction effect between cycle type (fresh vs frozen) and PGT was tested. RESULTS Of 28,153 included cycles, 3708 had PGT while 24,445 did not. PGT cycles were less likely to result in an embryo transfer (ET) (64 vs 94%), but were associated with increased rates of frozen ET (70 vs 41%), single ET (67 vs 44%), and blastocyst ET (87 vs 65%). There was a significant interaction between PGT and cycle type. Cycles using PGT increased the probability of a GBO 12% in frozen cycles (RR 1.12; 95% CI 1.02, 1.22; p = 0.018), but PGT was detrimental to success in fresh cycles with a 53% reduced likelihood of GBO (RR 0.47; 9% CI 0.41, 0.54; p < 0.001). CONCLUSION PGT, as practiced during the most recently available national data in women using fresh donor oocytes, was associated with increased probability of a healthy live birth amongst frozen cycles, but was not beneficial in fresh cycles.

[PMID: 32161819 PMCID: PMC7059854 DOI: 10.1093/hropen/hoaa005] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2019] [Revised: 01/07/2020] [Indexed: 12/14/2022] Open
Abstract
STUDY QUESTION Are data accurately documented in the Canadian Assisted Reproductive Technologies Register (CARTR) Plus database? SUMMARY ANSWER Measures of validity were strong for the majority of variables evaluated while those with moderate agreement were FSH levels, oocyte origin and elective single embryo transfer. WHAT IS KNOWN ALREADY Health databases and registries are excellent sources of data. However, as these databases are typically not established for the primary purpose of performing research, they should be evaluated prior to utilization for research both to inform the study design and to determine the extent to which key study variables, such as patient characteristics or therapies provided, are accurately documented in the database. CARTR Plus is Canada's national register for collecting extensive information on IVF and corresponding pregnancy outcomes, and it has yet to be validated. STUDY DESIGN SIZE DURATION This study evaluating the data translation CARTR Plus database examined IVF cycles performed in 2015 using data directly from patient charts. Six clinics across Canada were recruited to participate, using a purposive sampling strategy. Fixed random sampling was employed to select 146 patient cycles at each clinic, representing unique patients. Only a single treatment cycle record from a unique patient at each clinic was considered during chart selection. PARTICIPANTS/MATERIALS SETTING METHODS Twenty-five data elements (patient characteristics, treatments and outcomes) were reabstracted from patient charts, which were declared the reference standard. Data were reabstracted by two independent auditors with relevant clinical knowledge after confirming inter-rater reliability. These data elements from the chart were then compared to those in CARTR Plus. To determine the validity of these variables, we calculated kappa coefficients, sensitivity, specificity, positive predictive value and negative predictive value with 95% CI for categorical variables and calculated median differences and intraclass correlation coefficients (ICC) for continuous variables. MAIN RESULTS AND THE ROLE OF CHANCE Six clinics agreed to participate in this study representing five Canadian provinces. The mean age of patients was 35.5 years, which was similar between the two data sources, resulting in a near perfect level of agreement (ICC = 0.99; 95% CI: 0.99, 0.99). The agreement for FSH was moderate, ICC = 0.68 (95% CI: 0.64, 0.72). There was nearly perfect agreement for cycle type, kappa = 0.99 (95% CI: 0.98, 1.00). Over 90% of the cycles in the reabstracted charts used autologous oocytes; however, data on oocyte source were missing for 13% of cycles in CARTR Plus, resulting in a moderate degree of agreement, kappa = 0.45 (95% CI, 0.37, 0.52). Embryo transfer and number of embryos transferred had nearly perfect agreement, with kappa coefficients greater than 0.90, whereas that for elective single or double embryo transfer was much lower (kappa = 0.55; 95% CI: 0.49, 0.61). Agreement was nearly perfect for pregnancy type, and number of fetal sacs and fetal hearts on ultrasound, all with kappa coefficients greater than 0.90. LARGE-SCALE DATA N/A. LIMITATIONS REASONS FOR CAUTION CARTR Plus contains over 200 variables, of which only 25 were assessed in this study. This foundational validation work should be extended to other CARTR Plus database variables in future studies. WIDER IMPLICATIONS OF THE FINDINGS This study provides the first assessment of the quality of the data translation process of the CARTR Plus database, and we found very high quality for the majority of the variables that were analyzed. We identified key data points that are either too often lacking or inconsistent with chart data, indicating that changes in the data entry process may be required. STUDY FUNDING/COMPETING INTERESTS This study was funded by Canadian Institutes of Health Research (CIHR) (Grant Number FDN-148438) and by the Canadian Fertility and Andrology Society Research Seed Grant (Grant Number: N/A). The authors report no conflict of interest. TRIAL REGISTRATION NUMBER Not applicable.

[PMID: 31934507 PMCID: PMC6951292 DOI: 10.7717/peerj.8308] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2019] [Accepted: 11/28/2019] [Indexed: 12/16/2022] Open
Abstract
Twin pregnancies are associated with greater risk of neonatal morbidity and mortality than a singleton. This study was performed to investigate the twin pregnancy rate when two vitrified-warmed embryos are transferred in women of advanced reproductive age (≥35 years at the time of oocyte retrieval) and to evaluate the implications of findings in selecting candidates for elective single embryo transfer (eSET). A retrospective analysis of data which included 2,038 women aged 35–45 years, who underwent vitrified-warmed double embryo transfer (DET), from January 2013 to December 2016 was undertaken. Pregnancy and twin rates were estimated after stratifying by prognostic profile. The twin pregnancy rate was lower in women with poor prognosis (12/96, 12.5%) as compared with that in women with favorable prognosis (102/374, 27.3%) and average prognosis (78/346, 22.5%) with significant differences (P < 0.05). The twin rate for women with favorable prognosis was 29.2% (70/240) in the cycles of women aged 35–37 years, 26.8% (26/97) in the cycles of women aged 38–40 years and 16.2% (6/37) in the cycles of women >40 years. The twin rate for women with average prognosis was 25.8% (51/198) in the cycles of women aged 35–37 years, 22.0% (22/100) in the cycles of women aged 38–40 years and 10.4% (5/48) in the cycles of women >40 years. The twin rate for women with poor prognosis was 15.3% (9/59) in the cycles of women aged 35–37 years, 10.3% (3/29) in the cycles of women aged 38–40 years and 0% (0/8) in the cycles of women >40 years. From these results, it was concluded that women with a favorable or average prognosis have a high risk of twin pregnancies. The finding can be used to guide future practice: that is, performing eSET in women with favorable or average prognosis and DET in women with poor prognosis.

Abstract
PROBLEM/CONDITION Since the first U.S. infant conceived with assisted reproductive technology (ART) was born in 1981, both the use of ART and the number of fertility clinics providing ART services have increased steadily in the United States. ART includes fertility treatments in which eggs or embryos are handled in the laboratory (i.e., in vitro fertilization [IVF] and related procedures). Although the majority of infants conceived through ART are singletons, women who undergo ART procedures are more likely than women who conceive naturally to deliver multiple-birth infants. Multiple births pose substantial risks for both mothers and infants, including obstetric complications, preterm delivery (<37 weeks), and low birthweight (<2,500 g). This report provides state-specific information for the United States (including the District of Columbia and Puerto Rico) on ART procedures performed in 2016 and compares birth outcomes that occurred in 2016 (resulting from ART procedures performed in 2015 and 2016) with outcomes for all infants born in the United States in 2016. PERIOD COVERED 2016. DESCRIPTION OF SYSTEM In 1995, CDC began collecting data on ART procedures performed in fertility clinics in the United States as mandated by the Fertility Clinic Success Rate and Certification Act of 1992 (FCSRCA) (Public Law 102-493 [October 24, 1992]). Data are collected through the National ART Surveillance System (NASS), a web-based data collection system developed by CDC. This report includes data from 52 reporting areas (the 50 states, the District of Columbia, and Puerto Rico). RESULTS In 2016, a total of 197,706 ART procedures (range: 162 in Wyoming to 24,030 in California) with the intent to transfer at least one embryo were performed in 463 U.S. fertility clinics and reported to CDC. These procedures resulted in 65,964 live-birth deliveries (range: 57 in Puerto Rico to 8,638 in California) and 76,892 infants born (range: 74 in Alaska to 9,885 in California). Nationally, the number of ART procedures performed per 1 million women of reproductive age (15-44 years), a proxy measure of the ART use rate, was 3,075. ART use rates exceeded the national rate in 14 reporting areas (Connecticut, Delaware, the District of Columbia, Hawaii, Illinois, Maryland, Massachusetts, New Hampshire, New Jersey, New York, Pennsylvania, Rhode Island, Utah, and Virginia). ART use exceeded 1.5 times the national rate in nine states, including three (Illinois, Massachusetts, and New Jersey) that also had comprehensive mandated health insurance coverage for ART procedures (i.e., coverage for at least four oocyte retrievals). Nationally, among ART transfer procedures for patients using fresh embryos from their own eggs, the average number of embryos transferred increased with increasing age (1.5 among women aged <35 years, 1.7 among women aged 35-37 years, and 2.2 among women aged >37 years). Among women aged <35 years, the national elective single-embryo transfer (eSET) rate was 42.7% (range: 8.3% in North Dakota to 83.9% in Delaware). In 2016, ART contributed to 1.8% of all infants born in the United States (range: 0.3% in Puerto Rico to 4.7% in Massachusetts). ART also contributed to 16.4% of all multiple-birth infants, including 16.2% of all twin infants and 19.4% of all triplets and higher-order infants. ART-conceived twins accounted for approximately 96.5% (21,455 of 22,233) of all ART-conceived infants born in multiple deliveries. The percentage of multiple-birth infants was higher among infants conceived with ART (31.5%) than among all infants born in the total birth population (3.4%). Approximately 30.4% of ART-conceived infants were twins and 1.1% were triplets and higher-order infants. Nationally, infants conceived with ART contributed to 5.0% of all low birthweight (<2,500 g) infants. Among ART-conceived infants, 23.6% had low birthweight compared with 8.2% among all infants. ART-conceived infants contributed to 5.3% of all preterm (gestational age <37 weeks) infants. The percentage of preterm births was higher among infants conceived with ART (29.9%) than among all infants born in the total birth population (9.9%). The percentage of ART-conceived infants who had low birthweight was 8.7% among singletons, 54.9% among twins, and 94.9% among triplets and higher-order multiples; the corresponding percentages among all infants born were 6.2% among singletons, 55.4% among twins, and 94.6% among triplets and higher-order multiples. The percentage of ART-conceived infants who were born preterm was 13.7% among singletons, 64.2% among twins, and 97.0% among triplets and higher-order infants; the corresponding percentages among all infants were 7.8% for singletons, 59.9% for twins, and 97.7% for triplets and higher-order infants. INTERPRETATION Multiple births from ART contributed to a substantial proportion of all twins, triplets, and higher-order infants born in the United States. For women aged <35 years, who typically are considered good candidates for eSET, on average, 1.5 embryos were transferred per ART procedure, resulting in higher multiple birth rates than could be achieved with single-embryo transfers. Of the four states (Illinois, Massachusetts, New Jersey, and Rhode Island) with comprehensive mandated health insurance coverage, three (Illinois, Massachusetts, and New Jersey) had rates of ART use >1.5 times the national average. Although other factors might influence ART use, insurance coverage for infertility treatments accounts for some of the difference in per capita ART use observed among states because most states do not mandate any coverage for ART treatment. PUBLIC HEALTH ACTION Twins account for almost all of ART-conceived multiple births born in multiple deliveries. Reducing the number of embryos transferred and increasing use of eSET, when clinically appropriate, could help reduce multiple births and related adverse health consequences for both mothers and infants. Because multiple-birth infants are at increased risk for numerous adverse sequelae that cannot be ascertained from the data collected through NASS alone, long-term follow-up of ART infants through integration of existing maternal and infant health surveillance systems and registries with data available from NASS might be useful for monitoring adverse outcomes.

These procedures resulted in 59,334 live-birth deliveries (range: 55 in Wyoming to 7,802 in California) and 71,152 infants born (range: 68 in Wyoming to 9,176 in California). Nationally, the number of ART procedures performed per 1 million women of reproductive age (15-44 years), a proxy measure of the ART utilization rate, was 2,832. ART use exceeded the national rate in 13 reporting areas (California, Connecticut, Delaware, the District of Columbia, Hawaii, Illinois, Maryland, Massachusetts, New Hampshire, New Jersey, New York, Rhode Island, and Virginia). Nationally, among ART transfer procedures in patients using fresh embryos from their own eggs, the average number of embryos transferred increased with increasing age of the woman (1.6 among women aged <35 years, 1.8 among women aged 35-37 years, and 2.3 among women aged >37 years). Among women aged <35 years, the national elective single-embryo transfer (eSET) rate was 34.7% (range: 11.3% in Puerto Rico to 88.1% in Delaware). In 2015, ART contributed to 1.7% of all infants born in the United States (range: 0.3% in Puerto Rico to 4.5% in Massachusetts). ART also contributed to 17.0% of all multiple-birth infants, 16.8% of all twin infants, and 22.2% of all triplets and higher-order infants. The percentage of multiple-birth infants was higher among infants conceived with ART (35.3%) than among all infants born in the total birth population (3.4%). Approximately 34.0% of ART-conceived infants were twins and 1.0% were triplets and higher-order infants. Nationally, infants conceived with ART contributed to 5.1% of all low birthweight infants. Among ART-conceived infants, 25.5% had low birthweight, compared with 8.1% among all infants. ART-conceived infants contributed to 5.3% of all preterm (gestational age <37 weeks) infants. The percentage of preterm births was higher among infants conceived with ART (31.2%) than among all infants born in the total birth population (9.7%). Among singletons, the percentage of ART-conceived infants who had low birthweight was 8.7% compared with 6.4% among all infants born. The percentage of ART-conceived infants who were born preterm was 13.4% among singletons compared with 7.9% among all infants.

This type of mandated insurance coverage has been associated with greater use of ART and likely accounts for some of the difference in per capita ART use observed among states. PUBLIC HEALTH ACTION Twins account for the majority of ART-conceived multiple births. Reducing the number of embryos transferred and increasing use of eSET when clinically appropriate could help reduce multiple births and related adverse health consequences for both mothers and infants. State-based surveillance of ART might be useful for monitoring and evaluating maternal and infant health outcomes of ART in states with high ART use.

Abstract
PURPOSE The purpose of this study was to investigate reproductive outcomes following elective single blastocyst transfer (eSBT) compared with those of double blastocyst transfer (DBT) in advanced maternal age. METHODS This was a retrospective cohort study performed at an academic fertility center. All women aged 40 and over for whom in vitro fertilization (IVF) cycles were performed and in whom embryo culture was extended to the blastocyst stage were reviewed for possible inclusion. Exclusion criteria included the following: women with >3 previous IVF cycles, the use of donor or frozen oocytes, preimplantation genetic diagnosis/preimplantation genetic screening cycles, and cycles in which embryos did not reach the blastocyst stage on day 5. The study included 310 women; 148 were included in the eSBT group and 162 were included in the DBT group. Live birth rate (LBR) was the main outcome. Outcomes were analyzed using logistic regression, controlling for confounders. These confounders were embryo expansion, embryo quality, and the number of previous IVF cycles. RESULTS The mean age of the whole group was 41 ± 0.91 years, and the LBR was 21.6%. The eSBT group and the DBT group achieved similar clinical pregnancy rates (33 vs. 33%) (OR 1.04; 95%CI, 0.62-1.75) and LBRs (20 vs. 22.8%) (OR 1.43; 95% CI, 0.78-2.64). The multiple birth rate was lower in the eSBT group (0 vs. 16%, p = 0.02). The subgroup of women who had elective DBT (eDBT) achieved a higher LBR (20 vs. 30.6%) (OR 2.32; 95% CI, 1.16-4.68) and a higher multiple birth rate (0 vs. 22%, p = 0.001). Cycles with early blastocyst transfers were associated with lower LBRs compared with cycles with fully expanded blastocyst transfers (11 vs. 24%, p = 0.02). CONCLUSION The results of this study indicate that eSBT is associated with similar LBRs compared to the entire DBT cohort; however, when supernumerary blastocysts are available for cryopreservation, eDBT is associated with both higher LBRs and a higher number of multiple births. Studies assessing the cumulative LBR in advanced maternal age after single blastocyst transfer and subsequent frozen-thawed blastocyst transfers are needed.

Differences in pregnancy outcomes in donor egg frozen embryo transfer (FET) cycles following preimplantation genetic screening (PGS): a single center retrospective study. J Assist Reprod Genet 2016; 34:71-78. [PMID: 27853913 PMCID: PMC5330984 DOI: 10.1007/s10815-016-0832-z] [Citation(s) in RCA: 22] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2016] [Accepted: 10/23/2016] [Indexed: 11/27/2022] Open
Abstract
Purpose This study aims to test the hypothesis, in a single-center retrospective analysis, that live birth rates are significantly different when utilizing preimplantation genetic screening (PGS) compared to not utilizing PGS in frozen–thawed embryo transfers in our patients that use eggs from young, anonymous donors. The question therefore arises of whether PGS is an appropriate intervention for donor egg cycles. Methods Live birth rates per cycle and live birth rates per embryo transferred after 398 frozen embryo transfer (FET) cycles were examined from patients who elected to have PGS compared to those who did not. Blastocysts derived from donor eggs underwent trophectoderm biopsy and were tested for aneuploidy using array comparative genomic hybridization (aCGH) or next-generation sequencing (NGS), then vitrified for future use (test) or were vitrified untested (control). Embryos were subsequently warmed and transferred into a recipient or gestational carrier uterus. Data was analyzed separately for single embryo transfer (SET), double embryo transfer (DET), and for own recipient uterus and gestational carrier (GC) uterus recipients. Results Rates of implantation of embryos leading to a live birth were significantly higher in the PGS groups transferring two embryos (DET) compared to the no PGS group (GC, 72 vs. 56 %; own uterus, 60 vs. 36 %). The live birth implantation rate in the own uterus group for SET was higher in the PGS group compared to the control (58 vs. 36 %), and this almost reached significance but the live birth implantation rate for the SET GC group remained the same for both tested and untested embryos. Live births per cycle were nominally higher in the PGS GC DET and own uterus SET and DET groups compared to the non-PGS embryo transfers. These differences almost reached significance. The live birth rate per cycle in the SET GC group was almost identical. Conclusions Significant differences were noted only for DET; however, benefits need to be balanced against risks associated with multiple pregnancies. Results observed for SET need to be confirmed on larger series and with randomized cohorts.

Fertil Steril 2016; 106:1312-1318. [PMID: 27565258 DOI: 10.1016/j.fertnstert.2016.07.1112] [Citation(s) in RCA: 78] [Impact Index Per Article: 9.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2016] [Revised: 07/05/2016] [Accepted: 07/21/2016] [Indexed: 11/29/2022]
Abstract
OBJECTIVE To assess whether preimplantation genetic screening (PGS) is possible by testing for free embryonic DNA in spent IVF media from embryos undergoing trophectoderm biopsy. DESIGN Prospective cohort analysis. SETTING Academic fertility center. PATIENT(S) Seven patients undergoing IVF and 57 embryos undergoing trophectoderm biopsy for PGS. INTERVENTION(S) On day 3 of development, each embryo was placed in a separate media droplet. All biopsied embryos received a PGS result by array comparative genomic hybridization. Preimplantation genetic screening was performed on amplified DNA extracted from media and results were compared with PGS results for the corresponding biopsy. MAIN OUTCOME MEASURE(S) [1] Presence of DNA in spent IVF culture media. [2] Correlation between genetic screening result from spent media and corresponding biopsy. RESULT(S) Fifty-five samples had detectable DNA ranging from 2-642 ng/μL after a 2-hour amplification. Six samples with the highest DNA levels underwent PGS, rendering one result with a derivative log ratio SD (DLRSD) of <0.85 (a quality control metric of oligonucleotide array comparative genomic hybridization). The fluid sample and trophectoderm results were identical demonstrating (45XY, -13). Three samples were reamplified 1 hour later and tested showing improving DLRSD. One of the three samples with a DLRSD of 0.85 demonstrated (46XY), consistent with the biopsy. Overnight DNA amplification showed DNA in all samples. CONCLUSION(S) We demonstrate two novel findings: the presence of free embryonic DNA in spent media and a result that is consistent with trophectoderm biopsy. Improvements in DNA collection, amplification, and testing may allow for PGS without biopsy in the future.

Abstract
OBJECTIVE To compare the pregnancy and obstetric outcomes in elective single versus two cleavage-stage embryo transfer. METHODS Fresh cleavage-stage embryo transfer cycles between January, 2014 and October, 2015 were reviewed, including 39 single embryo transfer (eSET) cycles and 200 double embryo transfer (DET) cycles. The clinical pregnancy rates, implantation rates, multiple pregnancy rates, live birth rate, and obstetric outcomes (gestational age, preterm delivery rate and mean birth weight) were compared between the two groups. RESULTS The baseline characteristics were comparable between the two groups. The estradiol level on the day of trigger and the oocyte number were significantly higher in eSET group than in DET group (10654.4 pmol/L vs 8284.2 pmol/L and 8.4 vs 7.0, respectively). No significant difference was found in the pregnancy rate (56.4% vs 66.0%) or live birth rate (48.7% vs 51.5%) between the two groups, and their implantation rates differed significantly (56.4% vs 37.8%). No multiple pregnancies occurred in eSET group while the rate of multiple pregnancies was 22.7% in DET group. The gestational age and mean birth weight were significantly higher in eSET group (P<0.05), and the preterm delivery rate after DET was nearly three times of that after eSET, although this difference was not statistically significant. CONCLUSIONS Elective single embryo transfer can be performed without compromising the live birth rates. Multiple pregnancy rates can be significantly reduced with eSET, which also results in a higher chance of delivering a term singleton live birth compared with DET.
