Abstract
Objective To identify independent risk factors for placenta accreta spectrum among pregnancies conceived with assisted reproductive technology. Design Retrospective cohort study. Setting Tertiary hospital. Patients Individuals who conceived with assisted reproductive technology and reached 20 weeks' gestation or later from 2011 to 2017. Interventions Patient and cycle data was abstracted from hospital records and supplemented with state-level data. Poisson regression was used for multivariate analyses and reported as adjusted relative risks (aRR). Main Outcome Measures Clinical or histologic placenta accreta spectrum. Results Of 1,975 qualifying pregnancies, 44 (2.3%) met criteria for accreta spectrum at delivery. In the multivariate model, significant risk factors included low-lying placenta at delivery (aRR, 15.44; 95% CI 7.76-30.72), uterine factor infertility or prior uterine surgery (aRR, 4.68; 95% CI, 2.72-8.05), initial low-lying placentation that resolved (aRR, 3.83; 95% CI, 1.90-7.73), and use of frozen embryos (aRR, 3.02; 95% CI, 1.66-5.48). When the fresh vs frozen variable was replaced with controlled ovarian hyperstimulation, the final model did not change (aRR, 2.40 for unstimulated cycles, 95% CI, 1.32-4.38). With frozen transfers, the accreta rate was 16% when the endometrial thickness was < 6mm vs 3.8% with thicker endometrium (P=.02). Conclusions Among pregnancies conceived with assisted reproductive technology, accreta spectrum is associated with low placental implantation (even when resolved), uterine factor infertility and prior uterine surgery, and the use of frozen embryo transfer or unstimulated cycles.

Abstract
OBJECTIVE To define specific risk factors for placenta previa in pregnancies conceived with assisted reproductive technology (ART). DESIGN Retrospective cohort. SETTING Fertility centers and inpatient obstetric units in Massachusetts. PATIENT(S) Patients conceiving with ART and delivering at 20 weeks gestation or later between 2011 and 2017 in Massachusetts. INTERVENTION(S) Patient demographic and medical factors and specific components of their cycles. Data were obtained by linking vital records of the State of Massachusetts to reproductive clinic data obtained from the Society for Assisted Reproductive Technology Clinic Outcome Reporting System, and then supplementing this information with laboratory and obstetric data from 2 large academic hospitals. MAIN OUTCOME MEASURE Associations were tested between multiple cycle- and patient-related factors and placenta previa or low-lying placenta at delivery. After testing for confounders, multivariate models were adjusted for maternal age, history of prior cesarean delivery and birth plurality, and are reported as adjusted relative risks (aRR). RESULT(S) We included 18,939 pregnancies, with 553 (2.9%) having placenta previa at delivery. Advanced maternal age (aRR, 1.25; 95% confidence interval [CI], 1.06-1.48), endometriosis, (aRR, 2.22; 95% CI, 1.71-2.86), and controlled ovarian hyperstimulation (aRR, 1.33; 95% CI, 1.12-1.59) were associated with placenta previa, whereas multiple births (aRR, 0.63; 95% CI, 0.48-0.81) and a history of polycystic ovary syndrome or ovulation disorders (aRR, 0.59; 95% CI, 0.46-0.75) had negative associations. The endometriosis association was strong in nulliparas and the controlled ovarian hyperstimulation association was strong in parous patients in a stratified analysis. No association was seen with prior history of cesarean delivery. CONCLUSION(S) Patients conceiving with ART do not have the typical previa risk factors of prior cesarean delivery and multiple gestations, whereas endometriosis and fresh embryo transfers contributed moderate risk. The embryo transfer process itself may affect previa development in this population.

Polycystic ovary syndrome and risk of adverse pregnancy outcomes: a registry linkage study from Massachusetts. Hum Reprod 2022; 37:2690-2699. [PMID: 36149255 PMCID: PMC9627555 DOI: 10.1093/humrep/deac210] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2022] [Revised: 08/24/2022] [Indexed: 11/13/2022] Open
Abstract
STUDY QUESTION Do women with polycystic ovary syndrome (PCOS) have a greater risk of adverse pregnancy complications (gestational diabetes, preeclampsia, cesarean section, placental abnormalities) and neonatal outcomes (preterm birth, small for gestational age, prolonged delivery hospitalization) compared to women without a PCOS diagnosis and does this risk vary by BMI, subfertility and fertility treatment utilization? SUMMARY ANSWER Deliveries to women with a history of PCOS were at greater risk of complications associated with cardiometabolic function, including gestational diabetes and preeclampsia, as well as preterm birth and prolonged length of delivery hospitalization. WHAT IS KNOWN ALREADY Prior research has suggested that women with PCOS may be at increased risk of adverse pregnancy outcomes. However, findings have been inconsistent possibly due to lack of consistent adjustment for confounding factors, small samples size and other sources of bias. STUDY DESIGN, SIZE, DURATION Massachusetts deliveries among women ≥18 years old during 2013-2017 from state vital records linked to hospital discharges, observational stays and emergency department visits were linked to the Society for Assisted Reproductive Technology Clinic Outcome Reporting System (SART CORS) and the Massachusetts All-Payers Claims Database (APCD). PARTICIPANTS/MATERIALS, SETTING, METHODS PCOS was identified by ICD9 and ICD10 codes in APCD prior to index delivery. Relative risks (RRs) and 95% CI for pregnancy and delivery complications were modeled using generalized estimating equations with a log link and a Poisson distribution to take multiple cycles into account and were adjusted a priori for maternal age, BMI, race/ethnicity, education, plurality, birth year, chronic hypertension and chronic diabetes. Tests for homogeneity investigated differences between maternal pre-pregnancy BMI categories (<30, ≥30, <25 and ≥25 kg/m2) and between non-infertile deliveries and deliveries that used ART or had a history of subfertility (defined by birth certificates, SART CORS records, APCD or hospital records). MAIN RESULTS AND THE ROLE OF CHANCE Among 91 825 deliveries, 3.9% had a history of PCOS. Women with a history of PCOS had a 51% greater risk of gestational diabetes (CI: 1.38-1.65) and a 25% greater risk of preeclampsia (CI: 1.15-1.35) compared to women without a diagnosis of PCOS. Neonates born to women with a history of PCOS were more likely to be born preterm (RR: 1.17, CI: 1.06-1.29) and more likely to have a prolonged delivery hospitalization after additionally adjusting for gestational age (RR: 1.23, CI: 1.09-1.40) compared to those of women without a diagnosis of PCOS. The risk for gestational diabetes for women with PCOS was greater among women with a pre-pregnancy BMI <30 kg/m2. LIMITATIONS, REASONS FOR CAUTION PCOS was defined by ICD documentation prior to delivery so there may be women with undiagnosed PCOS or PCOS diagnosed after delivery included in the unexposed group. The study population is limited to deliveries within Massachusetts among most private insurance payers and inpatient or observational hospitalization in Massachusetts during the follow-up window, therefore there may be diagnoses and or deliveries outside of the state or outside of our sample that were not captured. WIDER IMPLICATIONS OF THE FINDINGS In this population-based study, women with a history of PCOS were at greater risk of pregnancy complications associated with cardiometabolic function and preterm birth. Obstetricians should be aware of patients' PCOS status and closely monitor for potential pregnancy complications to improve maternal and infant perinatal health outcomes.

Abstract
Numerous studies have demonstrated that assisted reproductive technology (ART: defined here as including only in vitro fertilization and related technologies) is associated with increased adverse pregnancy, neonatal, and childhood developmental outcomes, even in singletons. The comparison group for many had often been a fertile population that conceived without assistance. The Massachusetts Outcome Study of Assisted Reproductive Technology (MOSART) was initiated to define a subfertile population with which to compare ART outcomes. Over more than 10 years, we have used the MOSART database to study pregnancy abnormalities and delivery complications but also to evaluate ongoing health of women, infants, and children. This article will review studies from MOSART in the context of how they compare with those of other investigations. We will present MOSART studies that identified the influence of ART and subfertility/infertility on adverse pregnancy (pregnancy hypertensive disorder, gestational diabetes, placental abnormality) and delivery (preterm birth, low birthweight) outcomes as well as on maternal and child hospitalizations. We will provide evidence that although subfertility/infertility increases the risk of adverse outcomes, there is additional risk associated with the use of ART. Studies exploring the contribution of placental abnormalities as one factor adding to this increased ART-associated risk will be described.

Pregnancy outcomes among women with endometriosis and fibroids: registry linkage study in Massachusetts. Am J Obstet Gynecol 2022; 226:829.e1-829.e14. [PMID: 35108504 DOI: 10.1016/j.ajog.2021.12.268] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2021] [Revised: 12/21/2021] [Accepted: 12/29/2021] [Indexed: 12/18/2022]
Abstract
BACKGROUND Endometriosis and uterine fibroids are common gynecologic conditions associated with a greater risk for infertility. Previous research has suggested that these conditions are associated with adverse pregnancy outcomes, potentially because of increased utilization of fertility treatments. OBJECTIVE Our objective was to investigate whether women with a history of endometriosis or fibroids had a greater risk for adverse pregnancy outcomes and whether this risk varied by infertility history and fertility treatment utilization. STUDY DESIGN Deliveries (2013-2017) recorded in Massachusetts' vital records were linked to assisted reproductive technology data, hospital stays, and all-payer claims database. We identified endometriosis and fibroids diagnoses via the all-payer claims database before index delivery. Adjusted relative risks for pregnancy complications were modeled using generalized estimating equations with a log link and Poisson distribution. The influence of subfertility or infertility and assisted reproductive technology was also investigated. RESULTS Among 91,825 deliveries, 1560 women had endometriosis and 4212 had fibroids. Approximately 30% of women with endometriosis and 26% of women with fibroids experienced subfertility or infertility without utilizing assisted reproductive technology, and 34% of women with endometriosis and 21% of women with fibroids utilized assisted reproductive technology for the index delivery. Women with a history of endometriosis or fibroids were at a greater risk for pregnancy-induced hypertension, preeclampsia, or eclampsia (endometriosis relative risk, 1.17; fibroids relative risk, 1.08), placental abnormalities (endometriosis relative risk, 1.65; fibroids relative risk, 1.38), and cesarean delivery (endometriosis relative risk, 1.22; fibroids relative risk, 1.17) than women with no history of those conditions. Neonates born to women with a history of endometriosis or fibroids were also at a greater risk for preterm birth (endometriosis relative risk, 1.24; fibroids relative risk, 1.17). Associations between fibroids and low birthweight varied by fertility status or assisted reproductive technology (P homogeneity=.01) and were stronger among noninfertile women. CONCLUSION Endometriosis or fibroids increased the risk for adverse pregnancy outcomes, possibly warranting differential screening or treatment.

Abstract
OBJECTIVE To compare the obstetric and perinatal outcomes of deliveries conceived with embryos from single-step vs. sequential culture media systems. DESIGN Historical cohort of Massachusetts vital records linked to assisted reproductive technology clinic data from the Society for Assisted Reproductive Technology Clinic Outcome Reporting System and laboratory embryology data from two large academic hospital fertility centers. SETTING Not applicable. PATIENTS Patients with singleton live birth deliveries between 2004 and 2017 conceived with autologous assisted reproductive technology cycles with fresh blastocyst transfer using either single-step (n = 1,058) or sequential (n = 474) culture media systems. INTERVENTIONS None. MAIN OUTCOME MEASURES Associations of single-step vs. sequential culture with obstetric outcomes (mode of delivery, placental abnormalities, pregnancy-induced hypertension, and gestational diabetes) and perinatal outcomes (preterm birth, low birthweight, small-for-gestational-age, and large-for-gestational-age [LGA]) were assessed with multivariate logistic modeling, adjusted for maternal age, race/ethnicity, education, parity, insurance type, protein supplementation, oxygen concentration, fertilization method, and number of transferred embryos. RESULTS Compared with sequential culture, single-step culture was associated with increased odds of LGA (adjusted odds ratio 2.1, 95% confidence interval 1.04-4.22). There were no statistically significant differences between single-step and sequential culture media systems in the odds of placental abnormalities, pregnancy-induced hypertension, gestational diabetes, prematurity, small-for-gestational-age, or low birthweight. CONCLUSIONS Single-step culture is associated with increased odds of LGA, indicating that embryo culture media systems may affect perinatal outcomes.

Abstract
OBJECTIVE To investigate hospitalizations up to 8 years after live birth among women who used assisted reproductive technology (ART) or who were subfertile compared with women who conceived naturally. DESIGN Retrospective cohort. SETTING Deliveries among privately insured women aged ≥18 years between 2004 and 2017 from Massachusetts state vital records were linked to the Society for Assisted Reproductive Technology Clinic Outcome Reporting System and hospital observational/inpatient stays. PATIENT(S) We compared patients with ART, medically assisted reproduction (MAR), and unassisted subfertile (USF) delivery with those with fertile delivery. INTERVENTION(S) NA. MAIN OUTCOME MEASURE(S) Postdelivery hospitalization information was derived from the International Classification of Diseases codes for discharges and combined by type. The relative risks and 95% confidence intervals (CIs) of hospitalization for up to the first 8 years postdelivery were modeled. RESULT(S) Among 492,515 deliveries, 5.6% used ART, 1.6% used MAR, and 1.8% were USF. Compared with fertile deliveries, deliveries that used ART or MAR or were USF were more likely to have hospital utilization (inpatient or observational stay) for any reason for up to 8 years of follow-up (USF, adjusted relative risk [aRR], 1.18 [95% CI, 1.12-1.25]; MAR, aRR, 1.20 [1.13-1.27]; and ART, aRR, 1.29 [1.25-1.34]). Assisted reproductive technology deliveries had an increased risk of hospitalization for conditions of the cardiovascular system (aRR, 1.31 [95% CI, 1.20-1.41]), overweight/obesity (aRR, 1.30 [1.17-1.44]), diabetes (aRR, 1.25 [1.05-1.49]), reproductive tract (aRR, 1.62 [1.47-1.79]), digestive tract (aRR, 1.39 [1.30-1.49]), thyroid (aRR, 2.02 [1.80-2.26]), respiratory system (aRR, 1.13 [1.03-1.24]), and cancer (aRR, 1.40 [1.18-1.65]) up to 8 years after delivery. Deliveries with MAR and subfertility had similar patterns of hospitalization as ART deliveries. CONCLUSION(S) Women who conceived through fertility treatment or experienced subfertility were at increased risk of subsequent hospitalization resulting from a variety of chronic and acute conditions.

Abstract
Objective Caesarean section (CS) is more common following infertility treatment (IT) but the reasons why remain unclear and confounded. The Robson 10‐Group Classification System (TGCS) may further explain variation in CS rates. We assessed the association between mode of conception and CS across Robson groups. Design Population‐based cohort study. Setting Ontario, Canada, in a public healthcare system. Population 921 023 births, 2006–2014. Methods Modified Poisson regression produced relative risks (RR) and 95% confidence intervals, comparing the risk of CS among women with (1) subfertility without IT, (2) non‐invasive IT (OI, IUI) or (3) invasive IT (IVF)—each relative to (4) spontaneous conception (SC). Main outcome measures CS rate according to one of four modes of conception, overall and stratified by each of the TGCS groups. Results Relative to SC (26.9%), the risk of CS increased in those with subfertility without IT (RR 1.17, 95% CI 1.16–1.18), non‐invasive IT (RR 1.21, 95% CI 1.18–1.24) and invasive IT (RR 1.39, 95% CI 1.36–1.42). Within each Robson group, similar patterns of RRs were seen, but with markedly differing rates. For example, in Group 1 (nulliparous, singleton, cephalic at ≥37 weeks, with spontaneous labour), the respective rates were 15.0, 19.4, 18.7 and 21.9%; in Group 2 (nulliparous, singleton, cephalic at ≥37 weeks, without spontaneous labour), the rates were 35.9, 44.4, 43.2 and 54.1%; and in Group 8 (multiple pregnancy), they were 55.9, 67.5, 65.0 and 69.3%, respectively. Conclusions CS is relatively more common in women with subfertility and those receiving IT, an effect that persists across Robson groups. Tweetable abstract Caesarean delivery is more common in women with infertility independent of demographics and prenatal conditions. Caesarean delivery is more common in women with infertility independent of demographics and prenatal conditions.

Abstract
OBJECTIVE This study evaluates differences in child healthcare utilization by maternal fertility status in the first four years of life. STUDY DESIGN The retrospective cohort evaluated Massachusetts (MA) live born infants using data linked from clinical assisted reproductive technology (ART) data, birth certificates, and hospital discharge records. Hospital records of infants born 2004-2017 to mothers of fertile (no infertility treatments or indicators of infertility), unassisted subfertile (UF, indicators of infertility but no fertility treatment), medically assisted reproduction (MAR, non-ART assistance with reproduction) and ART treatment were studied. Adjusted relative risk (aRR) was calculated using multivariable log binomial regression models. RESULTS We included 339,426 singleton live-born infants discharged from birth hospitalization. Compared to children born to fertile mothers, those born to UF, MAR and ART-treated mothers were more likely to have hospital-based care (aRR 1.06-1.21) in their first 4 years. CONCLUSIONS Maternal subfertility with and without treatment was associated with small increases in child healthcare utilization.

Abstract
Introduction Assisted reproductive technologies (ART), such as in-vitro fertilisation (IVF), have revolutionised the treatment of infertility, with an estimated 8 million babies born worldwide. However, the long-term health outcomes for women and their offspring remain an area of concern. Linking IVF treatment data to long-term health data is the most efficient method for assessing such outcomes. Objectives To describe the creation and performance of a bespoke population-based data linkage of an ART clinical quality registry to state-based and national administrative datasets. Methods The linked dataset was created by deterministically and probabilistically linking the Australia and New Zealand Assisted Reproduction Database (ANZARD) to New South Wales (NSW) and Australian Capital Territory (ACT) administrative datasets (performed by NSW Centre for Health Record Linkage (CHeReL)) and to national claims datasets (performed by Australian Institute of Health and Welfare (AIHW)). The CHeReL’s Master Linkage Key (MLK) was used as a bridge between ANZARD’s partially identifiable patient data (statistical linkage key) and NSW and ACT administrative datasets. CHeReL then provided personal identifiers to the AIHW to obtain national content data. The results of the linkage were reported, and concordance between births recorded in ANZARD and perinatal data collections (PDCs) was evaluated. Results Of the 62,833 women who had ART treatment in NSW or ACT, 60,419 could be linked to the CHeReL MLK (linkage rate: 96.2%). A reconciliation of ANZARD-recorded births among NSW residents found that 94.2% (95% CI: 93.9–94.4%) of births were also recorded in state/territory-based PDCs. A high concordance was found in plurality status and birth outcome ≥99% agreement rate, Cohen’s kappa ranged: 0.78–0.98) between ANZARD and PDCs. Conclusion The data linkage resource demonstrates that high linkage rates can be achieved with partially identifiable data and that a population spine, such as the CHeReL’s MLK, can be successfully used as a bridge between clinical registries and administrative datasets.

Am J Obstet Gynecol 2021; 225:285.e1-285.e7. [PMID: 33894152 DOI: 10.1016/j.ajog.2021.04.235] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2021] [Revised: 04/06/2021] [Accepted: 04/17/2021] [Indexed: 11/26/2022]
Abstract
BACKGROUND Contemporary embryo biopsy in the United States involves the removal of several cells from a blastocyst that would become the placenta for preimplantation genetic testing. Embryos are then cryopreserved while patients await biopsy results, with transfers occurring in a subsequent cycle as a single frozen-thawed embryo transfer, if euploid. OBJECTIVE We sought to determine if removal of these cells for preimplantation genetic testing was associated with adverse obstetrical or neonatal outcomes after frozen-thawed single embryo transfer. STUDY DESIGN We linked assisted reproductive technology surveillance data from the Society for Assisted Reproductive Technology Clinic Outcome Reporting System to birth certificates and maternal and neonatal hospitalization discharge diagnoses in Massachusetts from 2014 to 2017, considering only singleton births after frozen-thawed single embryo transfers. We compared outcomes of cycles having embryo biopsy (n=585) to those having no biopsy (n=2191) using chi-square for categorical and binary variables and logistic regression for adjusted odds ratios and 95% confidence intervals, adjusting for mother's age, race, education, parity, body mass index, birth year, insurance, and all infertility diagnoses. RESULTS Considering no biopsy as the reference, there was no difference between groups with respect to preeclampsia (adjusted odds ratio, 0.82; 95% confidence interval, 0.42-1.61; P=.5685); pregnancy-induced hypertension (adjusted odds ratio, 0.85; 95% confidence interval, 0.46-1.59; P=.6146); placental disorders, including placental abruption, placenta previa, placenta accreta, placenta increta, and placenta percreta (adjusted odds ratio, 1.16; 95% confidence interval, 0.60-2.24; P=.6675); preterm birth (adjusted odds ratio, 1.22; 95% confidence interval 0.73-2.03; P=.4418); low birthweight (adjusted odds ratio, 1.12; 95% confidence interval, 0.58-2.15; P=.7355); cesarean delivery (adjusted odds ratio, 1.04; 95% confidence interval, 0.79-1.38; P=.7762); or gestational diabetes mellitus (adjusted odds ratio, 0.83; 95% confidence interval, 0.50-1.38; P=.4734). In addition, there was no difference between the groups for prolonged hospital stay for mothers (adjusted odds ratio, 1.23; 95% confidence interval, 0.83-1.80; P=.3014) or for infants (95% confidence interval, 1.29; 95% confidence interval, 0.72-2.29; P=.3923). CONCLUSION Embryo biopsy for preimplantation genetic testing does not increase the odds for diagnoses related to placentation (preeclampsia, pregnancy-related hypertension, placental disorders, preterm delivery, or low birthweight), maternal conditions (gestational diabetes mellitus), or maternal or infant length of stay after delivery.

Abstract
OBJECTIVE Assisted reproductive technology (ART)-treated women exhibit increased risk of premature delivery compared to fertile women. We evaluated whether ART treatment modalities increase prematurity and whether placental abnormalities and pregnancy-induced hypertensive (PIH) disorders mediate these risks. METHOD(S) This retrospective study of ART-treated and fertile deliveries (2004-2017) used an ART-cycle database linked to Massachusetts birth certificates and hospital discharges. Outcomes of late preterm birth (LPTB: 34-36 weeks gestation) and early preterm birth (EPTB: <34 weeks gestation) were compared with term deliveries (≥37 weeks gestation) in ART-treated (linked to the ART database) and fertile (no indicators of infertility or ART) deliveries. ART treatments with autologous oocyte, donor oocyte, fresh or frozen embryo transfer (FET), intracytoplasmic sperm injection (ICSI) and no-ICSI were separately compared to the fertile group. Adjusted odds ratios (AOR) were calculated with multivariable logistic regression: placental abnormalities or PIH were quantified in the pathway as mediators. RESULTS There were 218,320 deliveries: 204,438 fertile and 13,882 ART-treated. All treatment types increased prematurity (AOR 1.31-1.58, LPTB; AOR 1.34-1.48, EPTB). Placental abnormalities mediated in approximately 22% and 38% of the association with LPTB and EPTB, respectively. PIH mediated 25% and 33% of the association with LPTB and EPTB in FET and donor oocyte cycles, more than other treatments (<10% LPTB and <13% EPTB). CONCLUSIONS ART-treatment and all ART modalities increased LPTB and EPTB when compared with fertile deliveries. Placental abnormalities modestly mediated associations approximately equally, while PIH was a stronger mediator in FET and donor oocyte cycles. Reasons for differences require exploration.

Abstract
Purpose We previously developed a subfertile comparison group with which to compare outcomes of assisted reproductive technology (ART) treatment. In this study, we evaluated whether insurance claims data in the Massachusetts All Payers Claims Database (APCD) defined a more appropriate comparison group. Methods We used Massachusetts vital records of women who delivered between 2013 and 2017 on whom APCD data were available. ART deliveries were those linked to a national ART database. Deliveries were subfertile if fertility treatment was marked on the birth certificate, had prior hospitalization with ICD code for infertility, or prior fertility treatment. An infertile group included women with an APCD outpatient or inpatient ICD 9/10 infertility code prior to delivery. Fertile deliveries were none of the above. Demographics, health risks, and obstetric outcomes were compared among groups. Multivariable generalized estimating equations were used to calculate adjusted relative risk (aRR) and 95% confidence intervals (CI). Results There were 70,726 fertile, 4,763 subfertile, 11,970 infertile, and 7,689 ART-treated deliveries. Only 3,297 deliveries were identified as both subfertile and infertile. Both subfertile and infertile were older, and had more education, chronic hypertension, and diabetes than the fertile group and less than the ART-treated group. Prematurity (aRR = 1.15–1.17) and birthweight (aRR = 1.10–1.21) were increased in all groups compared with the fertile group. Conclusion Although the APCD allowed identification of more women than the previously defined subfertile categorization and allowed us to remove previously unidentified infertile women from the fertile group, it is not clear that it offered a clinically significantly improved comparison group.

Abstract
PURPOSE Investigate the relationship between history of cancer and adverse pregnancy outcomes according to subfertility/fertility treatment. METHODS Deliveries (2004-2013) from Massachusetts (MA) Registry of Vital Records and Statistics were linked to MA assisted reproductive technology data, hospital discharge records, and Cancer Registry. The relative risks (RR) and 95% confidence intervals of adverse outcomes (gestational diabetes (GDM), gestational hypertension (GHTN), cesarean section (CS), low birth weight (LBW), small for gestational age (SGA), preterm birth (PTB), neonatal mortality, and prolonged neonatal hospital stay) were modeled with log-link and Poisson distribution generalized estimating equations. Differences by history of subfertility/fertility treatment were investigated with likelihood ratio tests. RESULTS Among 662,630 deliveries, 2,983 had a history of cancer. Women with cancer history were not at greater risk of GDM, GHTN, or CS. However, infants born to women with prior cancer had higher risk of LBW (RR: 1.19 [1.07-1.32]), prolonged neonatal hospital stay (RR: 1.16 [1.01-1.34]), and PTB (RR: 1.19 [1.07-1.32]). We found clinically and statistically significant differences in the relationship between cancer history and SGA by subfertility/fertility treatment (p value, test for heterogeneity = 0.02); among deliveries with subfertility or fertility treatment, those with a history of cancer experienced a greater risk of SGA (RRsubfertile: 1.36 [1.02-1.83]). CONCLUSIONS Women with a history of cancer had greater risk of some adverse pregnancy outcomes; this relationship varied by subfertility and fertility treatment.

Abstract
PURPOSE Among infants following ART-treated, subfertile, and fertile deliveries to determine (1) the presence and magnitude of sex differences in health outcomes and (2) whether the presence of sex differences varied among maternal fertility groups. METHODS Retrospective cohort analysis of infants born in Massachusetts (MA) in 2004-2013 who were conceived by ART. The Society for Assisted Reproductive Technology Clinic Outcome Reporting System was linked to the Pregnancy to Early Life Longitudinal data system, which links birth certificates to hospital discharge records for MA mothers and infants. Included were singletons born via ART-treated, subfertile, and fertile deliveries. Multivariable logistic regression was used to model the association between infant sex and health outcomes, controlling for maternal demographic and health characteristics. RESULTS A total of 16,034 ART-treated, 13,277 subfertile, and 620,375 fertile singleton live births were included. For all three groups, males had greater odds of being preterm (AOR range 1.15-1.2), having birth defects (AOR range 1.31-1.71), experiencing respiratory (AOR range 1.33-1.35) and neurologic (AOR range 1.24-1.3) conditions, and prolonged hospital stay (AOR range 1.19-1.25) compared to females. The interaction between maternal fertility group and infant sex for all infant outcomes was nonsignificant, denoting that the presence of sex differences among fertile, subfertile, and ART groups did not vary. CONCLUSION Sex differences in birth outcomes of infants following ART-treated, subfertile, and fertile deliveries exist but the magnitude of these differences does not vary among these maternal fertility groups.

Abstract
OBJECTIVE To determine the maternal demographic, health, and fertility variables underlying prematurity. DESIGN Retrospective: Society for Assisted Reproductive Technology Clinic Outcome Reporting System data linked to Massachusetts birth certificates and hospital stays. SETTING Not applicable. PATIENTS We included 166,963 privately insured, singleton, first births to women ≥18 years of age between 2004 and 2013. Deliveries were as follows: assisted reproductive technology (ART) when linked to Society for Assisted Reproductive Technology Clinic Outcome Reporting System, medically assisted reproduction (MAR) when fertility treatment was indicated on the birth certificate, unassisted subfertile (USF) when there were indications of subfertility but no treatment, and fertile if none of the above. INTERVENTION None. MAIN OUTCOME MEASURES Late preterm birth (LPTB; 34-36 weeks) and early preterm birth (EPTB; <34 weeks) were compared with term deliveries (≥37 weeks). Covariates that statistically significantly influenced prematurity in binary analysis were modeled by using multinomial logistic regression. Backward elimination and mediation analysis were used to determine the influence of single parameters on outcomes of others. RESULTS LPTB was increased in the USF (adjusted odds ratio [AOR] 1.32, 95% confidence interval [CI] 1.06-1.65) and ART (AOR 1.42, 95% CI 1.30-1.56) but not MAR (AOR 1.16, 95% CI 0.98-1.37). ETPB was increased in all (USF: AOR 1.67, 95% CI 1.21-2.31; MAR: AOR 1.67, 95% CI 1.31-2.12; ART: AOR 1.40, 95% CI 1.21-1.61). The strongest effectors of prematurity were placental problems (LPTB: AOR 4.02; EPTB: AOR 10.28), pregnancy hypertension (LPTB: AOR 2.14; EPTB: AOR 2.88), and chronic hypertension (LPTB: AOR 1.85; EPTB: AOR 2.79). Mediation analysis demonstrated a statistically significant indirect effect of placental problems for ART and subfertility. CONCLUSION The greatest effectors of prematurity were placental problems and hypertensive disorders. ART and, to a lesser extent, subfertility were both associated with preterm birth directly and indirectly mediated by placenta problems.

Abstract
INTRODUCTION We examined the prevalence of autism spectrum disorders (ASDs) in Massachusetts (MA) comparing children born via assisted reproductive technology (ART) and children born to women with indicators of subfertility but no ART (Subfertile), to children born to women with neither ART nor indicators of subfertility (Fertile). We assessed the direct, indirect, and total effects of ART and subfertility on ASD among singletons. METHODS This study included 10,147 ART, 8072 Subfertile and 441,898 Fertile MA resident births from the MA Outcome Study of ART (MOSART) database linked with Early Intervention program participation data. ART included fresh in vitro fertilization (IVF), fresh intracytoplasmic sperm injection (ICSI), and frozen embryo transfer. We estimated the prevalence of ASD by fertility group. We used logistic regression to assess the natural direct effect (NDE), natural indirect effect (NIE) through preterm birth, and total effects of each fertility group on ASD. RESULTS The NDE indicated that, compared to the Fertile group, the odds of ASD were not statistically higher in the ART (ORNDE 1.07; 95% CI 0.88-1.30), Subfertile (ORNDE 1.11; 95% CI 0.89-1.38), IVF (ORNDE 0.91; 95% CI 0.68-1.22), or ICSI (ORNDE 1.13; 95% CI 0.84-1.51) groups, even if the rate of preterm birth was the same across all groups. The total effect (product of NDE and NIE) was not significant for ART (ORTotal Effect 1.08; 95% CI 0.89-1.30), Subfertile (ORTotal Effect 1.11; 95% CI 0.89-1.38), IVF (ORTotal Effect 0.92; 95% CI 0.69-1.23), or ICSI (ORTotal Effect 1.13; 95% CI 0.84-1.52). CONCLUSION Compared to children born to Fertile women, children born to ART, ICSI, or IVF, or Subfertile women are not at increased risk of receiving an ASD diagnosis.

Abstract
OBJECTIVE To compare incidence, risk factors, and etiology of women's deaths in fertile, subfertile, and undergoing assisted reproductive technology (ART) in the years after delivery. DESIGN Retrospective cohort. SETTING University hospital. PATIENT(S) Women who had delivered in Massachusetts. INTERVENTION(S) This study used data from the Society for Assisted Reproductive Technology Clinic Outcome Reporting System linked to vital records, hospital stays, and the Massachusetts death file. Mortality of patients delivered from 2004-2013 was evaluated through 2015. The exposure groups, determined on the basis of the last delivery, were ART-treated (linked to Society for Assisted Reproductive Technology Clinic Outcome Reporting System), subfertile (no ART but with indicators of subfertility including birth certificate checkbox for fertility treatment, prior hospitalization for infertility [International Classification of Disease codes 9 628 or V23], and/or prior delivery with checkbox or ART), or fertile (neither ART nor subfertile). Numbers (per 100,000 women-years) and causes of death were obtained from the Massachusetts death file. MAIN OUTCOME MEASURE(S) Mortality of women after delivery in each of the three fertility groups and the most common etiology of death in each. RESULT(S) We included 483,547 women: 16,429 ART, 11,696 subfertile, and 455,422 fertile among whom there were 1,280 deaths with 21.1, 25.5, and 44.7 deaths, respectively, per 100,000 women-years. External causes (violence, accidents, and poisonings) were the most common reasons for death in the fertile group. Deaths occurred on average 46 months after delivery. When external causes of death were removed, there were 19.1, 17.0, and 25.6 deaths per 100,000 women-years and leading causes of death in all groups were cancer and circulatory problems. CONCLUSION(S) The study presents reassuring data that death rates within 5 years of delivery in ART-treated and subfertile women do not differ from those in fertile women.

Abstract
OBJECTIVE To compare neonatal health outcomes after fresh versus frozen ET (FET). DESIGN Retrospective analysis of a population-based database of linked clinically assisted reproductive technology (ART) data with state vital records. Multivariable logistic regression was used to model the association between deliveries from fresh versus FET and adverse health outcomes, controlling for maternal characteristics. SETTING Not applicable. PATIENT(S) Live-born singleton infants born to Massachusetts women who conceived by fresh or FET after ART using autologous oocytes between July 1, 2004, and December 31, 2013. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Preterm birth, low birth weight, neonatal mortality, birth defects, organ system conditions. RESULT(S) Compared with infants conceived from fresh embryos, those born to mothers who underwent FET were less likely to be small for gestational age (adjusted odds ratio [AOR] = 0.56; 95% confidence interval [CI], 0.44-0.70) and low birth weight (AOR = 0.72; 95% CI, 0.59-0.88) but more likely to be large for gestational age (AOR = 1.47; 95% CI, 1.26-1.70) and to experience greater odds of infectious disease (AOR = 1.46; 95% CI, 1.03-2.06), respiratory (AOR = 1.23; 95% CI, 1.07-1.41), and neurologic (AOR = 1.32; 95% CI, 1.04-1.68) conditions. There were no statistically significant differences in preterm birth, neonatal mortality, birth defects, cardiovascular, hematologic, and gastrointestinal/feeding conditions, and for infants ≥ 35 weeks, no statistically significant differences in prolonged hospital stay (>3 days for vaginal delivery, >5 days for cesarean). CONCLUSION(S) Compared with infants conceived from fresh ET, those born by FET have higher birth weight but increased odds of infectious disease, hematologic, respiratory, and neurologic abnormalities. These risks should be considered when making decisions on fresh versus FET.

Abstract
PURPOSE Pre-pregnancy and post-delivery hospitalizations were compared as markers for health among women who conceived using assisted reproductive technology (ART), non-ART medically assisted reproduction (MAR), no treatment (unassisted subfertile), and who were fertile. METHODS We analyzed hospital discharge data linked to Massachusetts birth certificates from 2004 to 2013 within 5 years prior to pregnancy and 8-365 days post-delivery. ART deliveries were linked from a national ART database; MAR deliveries had fertility treatment but not ART; unassisted subfertile women had subfertility but no ART or MAR; and fertile women had none of these. Prevalence of diagnoses during hospitalization was quantified. Multivariable logistic regression models with fertile deliveries as reference were adjusted for maternal age, race, education, year, and plurality (post-delivery only) with results reported as adjusted odds ratios (AORs) and 95% confidence intervals (CI). RESULTS Of 170,605 privately insured, primiparous deliveries, 10,458 were ART, 3005 MAR, 1365 unassisted subfertile, and 155,777 fertile. Pre-pregnancy hospitalization occurred in 6.8% and post-delivery in 2.8% of fertile women. Subfertile groups had more pre-pregnancy hospitalizations (AOR, 95% CI: 1.84, 1.72-1.96 ART; 1.41, 1.24-1.60 MAR; 3.02, 2.62-3.47 unassisted subfertile) with endometriosis, reproductive organ disease, ectopic pregnancy/miscarriage, and disorders of menstruation, ovulation, and genital tract being common. Post-delivery hospitalizations were significantly more frequent in the ART (AOR 1.19, 95% CI 1.05-1.34) and unassisted subfertile (1.59, 1.23-2.07) groups with more digestive tract disorders, thyroid problems, and other grouped chronic disease conditions. CONCLUSIONS Greater likelihood of hospitalization in the ART, MAR, and unassisted subfertile groups is largely explained by admissions for conditions associated with subfertility.

Abstract
STUDY QUESTION Are routinely collected data from fertility populations adequately validated? SUMMARY ANSWER Of the 19 studies included, only one validated a national fertility registry and none reported their results in accordance with recommended reporting guidelines for validation studies. WHAT IS KNOWN ALREADY Routinely collected data, including administrative databases and registries, are excellent sources of data, particularly for reporting, quality assurance, and research. However, these data are subject to misclassification bias due to misdiagnosis or errors in data entry and therefore need to be validated prior to using for clinical or research purposes. STUDY DESIGN SIZE DURATION We conducted a systematic review by searching Medline, Embase, and CINAHL from inception to 6 October 2016 to identify validation studies of databases that contain routinely collected data in an ART setting. Webpages of international ART centers were also searched. PARTICIPANTS/MATERIALS SETTING METHODS We included studies that compared at least two data sources to validate ART population data. Key words and MeSH terms were adapted from previous systematic reviews investigating routinely collected data (e.g. administrative databases and registries), measures of validity (including sensitivity, specificity, and predictive value), and ART (including infertility, IVF, advanced reproductive age, and diminished ovarian reserve). Only full-text studies in English were considered. Results were synthesized qualitatively. The electronic search yielded 1074 citations, of which 19 met the inclusion criteria. MAIN RESULTS AND THE ROLE OF CHANCE Two studies validated a fertility database using medical records; seven studies used an IVF registry to validate vital records or maternal questionnaires, and two studies failed to adequately describe their reference standard. Four studies investigated the validity of mode of conception from birth registries; two studies validated diagnoses or treatments in a fertility database; four studies validated a linkage algorithm between a fertility registry and another administrative database; one study created an algorithm in a single database to identify a patient population. Sensitivity was the most commonly reported measure of validity (12 studies), followed by specificity (9 studies). Only three studies reported four or more measures of validation, and five studies presented CIs for their estimates. The prevalence of the variable in the target population (pre-test prevalence) was reported in seven studies; however, only four of the studies had prevalence estimates from the study population (post-test prevalence) within a 2% range of the pre-test estimate. The post-test estimate was largely discrepant from the pre-test value in two studies. LIMITATIONS REASONS FOR CAUTION The search strategy was limited to the studies and reports published in English, which may not capture validation studies from countries that do not speak English. Furthermore, only three specific fertility-based diagnostic variables (advanced reproductive age, diminished ovarian reserve, and chorionicity) were searched in Medline, Embase, and CINAHL. Consequently, published studies with other diagnoses or conditions relevant to infertility may not have been captured in our review. WIDER IMPLICATIONS OF THE FINDINGS There is a paucity of literature on validation of routinely collected data from a fertility population. Furthermore, the prevalence of the markers that have been validated are not being presented, which can lead to biased estimates. Stakeholders rely on these data for monitoring outcomes of treatments and adverse events; therefore, it is essential to ascertain the accuracy of these databases and make the reports publicly available. STUDY FUNDING/COMPETING INTERESTS This study was supported by Canadian Institutes of Health Research (CIHR) (FDN-148438). There are no competing interests for any of the authors.

Abstract
OBJECTIVE To quantify the effect of medical and obstetrical factors on the odds of cesarean delivery, comparing assisted reproductive technology (ART)-treated women and women with subfertility not treated with ART versus fertile women. DESIGN Retrospective cohort. SETTING Not applicable. PATIENT(S) Singleton deliveries to primiparous women; with the source of this data being the Massachusetts vital and hospital records linked to the Society for Assisted Reproductive Technology Clinic Outcome Reporting System data (2004-2010). INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Mode of delivery. RESULT(S) The 173,130 deliveries included 5,768 ART-treated, 2,657 subfertile (1,627 non-ART medically assisted reproduction [MAR] and 1,030 unassisted infertile), and 164,705 fertile pregnancies and 117,743 vaginal and 55,387 cesarean deliveries. ART-treated women were older, more often white and non-Hispanic, and with more private insurance, previous uterine surgery, gestational diabetes, pregnancy hypertension, bleeding, and placental complications than fertile women. Overall rates of cesarean delivery were 45.7%, 43.3%, and 31.1% for ART-treated, subfertile, and fertile women and 41.7% and 45.9% for MAR and unassisted infertile deliveries. When adjusted for demographics, underlying medical factors, previous uterine surgery, and placental and delivery complications, adjusted odds ratios (ORs) compared with fertile women were 1.27 for ART-treated and 1.15 for subfertile women, with greater odds among unassisted infertile (OR 1.26) but not MAR (OR 1.09) women. The strongest confounders of odds of cesarean delivery were age and previous uterine surgery. CONCLUSION(S) ART and unassisted infertility were associated with greater odds of cesarean compared with fertile women. Underlying medical and obstetrical risks had strong confounding effects strongly attenuating the odds for cesarean delivery.

Abstract
Objectives To describe the implementation of the first phase of a regional perinatal data repository and to provide a roadmap for others to navigate technical, privacy, and data governance concerns in implementing similar resources. Methods Our implementation integrated regional physician billing records with maternal and infant electronic health records from an academic delivery hospital. These records, representing births during 2013-2015, constituted a data core supporting linkage to additional ancillary data sets. Measures obtained from pediatric follow-up, urgent care, emergency, and inpatient encounters were linked at the individual level as were measures obtained by home visitors during pre- and postnatal encounters. Residential addresses were geocoded supporting linkage to area-level measures. Results Integrated data contained regional billing records for 69,290 newborns representing approximately 81% of all regional live births and nearly 95% of live births in the region's most populous county. Billing records linked to 7293 infant delivery hospital records and 7107 corresponding maternal hospital records. Manual review demonstrated 100% validity of matches among audited records. Additionally, 2430 home visiting records were linked to the data core as were pediatric primary care, urgent care, emergency department, and inpatient visits representing 42,541 children. More than 99% of the newborn billing records were geocoded and assigned a census tract identifier. Conclusions for Practice Our approach to methodological and regulatory challenges affords opportunities for expansion of systems to integrate electronic health records originating from additional medical centers as well as individual- and area-level linkage to additional data sets relevant to perinatal health.

Abstract
With advanced perinatal care and technology, survival among infants born very preterm (<32 weeks gestation) has improved dramatically over the last several decades. However, adverse medical and neurodevelopmental outcomes for those born very preterm remains high, particularly at the lowest gestational ages. Public health plays a critical role in providing data to assess population-based risks associated with very preterm birth, addressing disparities, and identifying opportunities for prevention, including improving the health of reproductive-age women, before, during, and after pregnancy.

Abstract
PURPOSE To determine whether differences in birth outcomes among assisted reproductive technology (ART)-treated, subfertile, and fertile women exist in primiparous women with, singleton, vaginal deliveries. METHODS Society for Assisted Reproductive Technology Clinic Outcome Reporting System (SART CORS) data were linked to Massachusetts vital records and hospital discharges for deliveries between July 2004 and December 2010. Primiparous women with in-state vaginal deliveries, adequate prenatal care, and singleton birth at ≥ 20 weeks (n = 117,779) were classified as ART-treated (linked to ART data from SART CORS, n = 3138); subfertile (not ART-treated but with indicators of subfertility, n = 1507); or fertile (neither ART-treated nor subfertile, n = 113,134). Outcomes of prematurity (< 37 weeks), low birthweight (< 2500 g), perinatal death (death at ≥ 20 weeks to ≤ 7 days), and maternal prolonged length of hospital stay (LOS > 3 days) were compared using multivariable logistic regression. RESULTS Compared to fertile, higher odds were found for prematurity among ART-treated (adjusted odds ratio [AOR] 1.40, 95% confidence interval [CI] 1.25-1.50) and subfertile (AOR 1.25, 95% CI 1.03-1.50) women, low birthweight among ART-treated (AOR 1.41, 95% CI 1.23-1.62) and subfertile (AOR 1.40, 95% CI 1.15-1.71) women, perinatal death among subfertile (AOR 2.64, 95% CI 1.72-4.05), and prolonged LOS among ART-treated (AOR 1.33, 95% CI 1.19-1.48) women. Differences remained despite stratification by young age and absence of pregnancy/delivery complications. CONCLUSIONS Greater odds of prematurity and low birthweight in ART-treated and subfertile, and perinatal death in subfertile deliveries are evident among singleton vaginal deliveries. The data suggest that even low-risk pregnancies to ART-treated and subfertile women be managed for adverse outcomes.

Abstract
OBJECTIVES To assess the risk of adverse health outcomes for infants after assisted reproductive technology (ART)-treated and subfertile as compared with fertile deliveries. METHODS Live-born singleton infants ≥23 weeks' gestational age (GA) born in Massachusetts between July 1, 2004, and December 31, 2010, were analyzed by linking a clinical ART database with state vital records. χ2 tests were used to compare the outcomes of fertile (those without ART treatment or other indicators of infertility), subfertile (indicators of infertility, no ART), and ART-treated (linked to ART deliveries) mothers, stratified by GA. Adjusted odds ratios (aORs) and 95% confidence intervals (CIs) were calculated by using multivariate logistic regression within each GA stratum, controlling for maternal sociodemographic and health characteristics. RESULTS Compared with infants of fertile mothers (n = 336 705), infants born to subfertile (n = 5043) or ART-treated (n = 8375) mothers were more likely to be preterm (aOR 1.39 [95% CI 1.26-1.54] and aOR 1.72 [95% CI 1.60-1.85], respectively) and have respiratory and gastrointestinal and/or nutritional conditions (aOR range: 1.12-1.18). When stratified by GA, infants of subfertile or ART-treated mothers were at greater risk for congenital malformations and infectious diseases as well as cardiovascular and respiratory conditions (aOR range: 1.30-2.61; 95% CI range: 1.02-4.59). Compared with infants born to subfertile mothers, infants born to ART-treated mothers were at lower risk for being small for GA and having congenital malformations and cardiovascular conditions and at higher risk for infectious disease conditions. CONCLUSIONS Compared with infants born to fertile mothers, infants of subfertile and ART-treated mothers are at greater risk for adverse health outcomes at birth beyond prematurity. The occurrence and magnitude of these risks vary by GA and organ systems.

Abstract
BACKGROUND It is unknown whether the risk of adverse outcomes in twin pregnancies among subfertile women, conceived with and without in vitro fertilization, differs from those conceived spontaneously. OBJECTIVE We sought to evaluate the effects of fertility status on adverse perinatal outcomes in twin pregnancies on a population basis. STUDY DESIGN All twin live births of ≥22 weeks' gestation and ≥350 g birthweight to Massachusetts resident women in 2004 through 2010 were linked to hospital discharge records, vital records, and in vitro fertilization cycles. Women were categorized by their fertility status as in vitro fertilization, subfertile, or fertile, and by twin pair genders (all, like, unlike). Women whose births linked to in vitro fertilization cycles were classified as in vitro fertilization; those with indicators of subfertility but without in vitro fertilization treatment were classified as subfertile; all others were classified as fertile. Risks of 6 adverse pregnancy outcomes (gestational diabetes, pregnancy hypertension, uterine bleeding, placental complications [placenta abruptio, placenta previa, and vasa previa], prenatal hospitalizations, and primary cesarean) and 9 adverse infant outcomes (very low birthweight, low birthweight, small-for-gestation birthweight, large-for-gestation birthweight, very preterm [<32 weeks], preterm, birth defects, neonatal death, and infant death) were modeled by fertility status with the fertile group as reference, using multivariate log binomial regression and reported as adjusted relative risk ratios and 95% confidence intervals. RESULTS The study population included 10,352 women with twin pregnancies (6090 fertile, 724 subfertile, and 3538 in vitro fertilization). Among all twins, the risks for all 6 adverse pregnancy outcomes were significantly increased for the subfertile and in vitro fertilization groups, with highest risks for uterine bleeding (adjusted relative risk ratios, 1.92 and 2.58, respectively) and placental complications (adjusted relative risk ratios, 2.07 and 1.83, respectively). Among all twins, the risks for those born to subfertile women were significantly increased for very preterm birth and neonatal and infant death (adjusted relative risk ratios, 1.36, 1.89, and 1.87, respectively). Risks were significantly increased among in vitro fertilization twins for very preterm birth, preterm birth, and birth defects (adjusted relative risk ratios, 1.28, 1.07, and 1.26, respectively). CONCLUSION Risks of all maternal and most infant adverse outcomes were increased for subfertile and in vitro fertilization twins. Among all twins, the highest risks were for uterine bleeding and placental complications for the subfertile and in vitro fertilization groups, and neonatal and infant death in the subfertile group. These findings provide further evidence supporting single embryo transfer and more cautious use of ovulation induction.

Am J Obstet Gynecol 2017; 217:327.e1-327.e14. [PMID: 28400311 DOI: 10.1016/j.ajog.2017.04.006] [Citation(s) in RCA: 70] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2017] [Revised: 03/28/2017] [Accepted: 04/03/2017] [Indexed: 01/21/2023]
Abstract
BACKGROUND Births to subfertile women, with and without infertility treatment, have been reported to have lower birthweights and shorter gestations, even when limited to singletons. It is unknown whether these decrements are due to parental characteristics or aspects of infertility treatment. OBJECTIVE The objective of the study was to evaluate the effect of maternal fertility status on the risk of pregnancy, birth, and infant complications. STUDY DESIGN All singleton live births of ≥22 weeks' gestation and ≥350 g birthweight to Massachusetts resident women in 2004-2010 were linked to hospital discharge and vital records. Women were categorized by their fertility status as in vitro fertilization, subfertile, or fertile. Women whose births linked to in vitro fertilization cycles from the Society for Assisted Reproductive Technology Clinic Outcomes Reporting System were classified as in vitro fertilization. Women with indicators of subfertility but not treated with in vitro fertilization were classified as subfertile. Women without indicators of subfertility or in vitro fertilization treatment were classified as fertile. Risks of 15 adverse outcomes (gestational diabetes, pregnancy hypertension, antenatal bleeding, placental complications [placenta abruptio and placenta previa], prenatal hospitalizations, primary cesarean delivery, very low birthweight [<1500 g], low birthweight [<2500 g], small-for-gestation birthweight [z-score ≤-1.28], large-for-gestation birthweight [z-score ≥1.28], very preterm [<32 weeks], preterm [<37 weeks], birth defects, neonatal death [0-27 days], and infant death [0-364 days of life]) were modeled by fertility status with the fertile group as reference and the subfertile group as reference, using multivariate log binomial regression and reported as adjusted risk ratios and 95% confidence intervals. RESULTS The study population included 459,623 women (441,420 fertile, 8054 subfertile, and 10,149 in vitro fertilization). Women in the subfertile and in vitro fertilization groups were older than their fertile counterparts. Risks for 6 of 6 pregnancy outcomes and 6 of 9 infant outcomes were increased for the subfertile group, and 5 of 6 pregnancy outcomes and 7 of 9 infant outcomes were increased for the in vitro fertilization group. For 4 of the 6 pregnancy outcomes (uterine bleeding, placental complications, prenatal hospitalizations, and primary cesarean) and 2 of the infant outcomes (low birthweight and preterm) the risk was greater in the in vitro fertilization group, with nonoverlapping confidence intervals to the subfertile group, indicating a substantially higher risk among in vitro fertilization-treated women. The highest risks for the in vitro fertilization women were uterine bleeding (adjusted risk ratio, 3.80; 95% confidence interval, 3.31-4.36) and placental complications (adjusted risk ratio, 2.81; 95% confidence interval, 2.57-3.08), and for in vitro fertilization infants, very preterm birth (adjusted risk ratio, 2.13; 95% confidence interval, 1.80-2.52), and very low birthweight (adjusted risk ratio, 2.15; 95% confidence interval, 1.80-2.56). With subfertile women as reference, risks for the in vitro fertilization group were significantly increased for uterine bleeding, placental complications, prenatal hospitalizations, primary cesarean delivery, low and very low birthweight, and preterm and very preterm birth. CONCLUSION These analyses indicate that, compared with fertile women, subfertile and in vitro fertilization-treated women tend to be older, have more preexisting chronic conditions, and are at higher risk for adverse pregnancy outcomes, particularly uterine bleeding and placental complications. The greater risk in in vitro fertilization-treated women may reflect more severe infertility, more extensive underlying pathology, or other unfavorable factors not measured in this study.

Abstract
PURPOSE The aim of this study is to evaluate frequency of hospitalization before, during, and after assisted reproductive technology (ART) treatment by cycle outcome. METHODS Six thousand and one hundred thirty women residing in Massachusetts undergoing 17,135 cycles of ART reported to the Society for Assisted Reproductive Technology Clinic Outcome Reporting System (SARTCORS) from 2004 to 2011 were linked to hospital discharges and vital records. Women were grouped according to ART treatment cycle outcome as: no pregnancy (n = 1840), one or more pregnancies but no live birth (n = 968), or one or more singleton live births (n = 3322). Hospital delivery discharges during 1998-2011 were categorized as occurring before, during, or after the ART treatment. The most prevalent ICD-9 codes for non-delivery hospital discharges were compared. Groups were compared using chi square test using SAS 9.3 software. RESULTS The proportion of any hospitalization was 57.0, 58.3, and 91.3% for women with no pregnancy, no live birth, and ART singleton live birth, respectively; the proportion of non-delivery hospitalizations was 30.4, 31.0, and 28.3%, respectively. The non-ART delivery proportion after ART treatment did not differ by group (33.4, 36.2, and 36.9%, respectively, p = 0.17). Most frequent non-delivery diagnoses (including fibroids, obesity, ectopic pregnancy, depression, and endometriosis) also did not differ by group. A secondary analysis limited to only women with no delivery discharges before the first ART cycle showed similar results. CONCLUSIONS All groups had live birth deliveries during the study period, suggesting an important contribution of non-ART treatment or treatment-independent conception to overall delivery and live births. Hospitalizations not associated with delivery suggested similarity in morbidity for all ART patients regardless of success with ART treatment.

Abstract
OBJECTIVE To better address barriers arising from missing and unreliable identifiers in neonatal medical records, we evaluated agreement and discordance among traditional and non-traditional linkage fields within a linked neonatal data set. STUDY DESIGN The retrospective, descriptive analysis represents infants born from 2013 to 2015. We linked children's hospital neonatal physician billing records to newborn medical records originating from an academic delivery hospital and evaluated rates of agreement, discordance and missingness for a set of 12 identifier field pairs used in the linkage algorithm. RESULTS We linked 7293 of 7404 physician billing records (98.5%), all of which were deemed valid upon manual review. Linked records contained a mean of 9.1 matching and 1.6 non-matching identifier pairs. Only 4.8% had complete agreement among all 12 identifier pairs. CONCLUSION Our approach to selection of linkage variables and data formatting preparatory to linkage have generalizability, which may inform future neonatal and perinatal record linkage efforts.

Abstract
BACKGROUND Assisted reproductive technology (ART) has been associated with birth defects, but the contributions of multiple births and underlying subfertility remain unclear. We evaluated the effects of subfertility and mediation by multiple births on associations between ART and nonchromosomal birth defects. METHODS We identified a retrospective cohort of Massachusetts live births and stillbirths from 2004 to 2010 among ART-exposed, ART-unexposed subfertile, and fertile mothers using linked information from fertility clinics, vital records, hospital discharges, and birth defects surveillance. Log-binomial regression was used to estimate prevalence ratios and 95% confidence intervals (CIs). Mediation analyses were performed to deconstruct the ART-birth defects association into the direct effect of ART, the indirect effect of multiple births, and the effect of ART-multiples interaction. RESULTS Of 17,829 ART-exposed births, 355 had a birth defect, compared with 162 of 9431 births to subfertile mothers and 6183 of 445,080 births to fertile mothers. The adjusted prevalence ratio was 1.5 (95% CI, 1.3-1.6) for ART and 1.3 (95% CI, 1.1-1.5) in subfertile compared with fertile deliveries. We observed elevated rates of several birth defects with ART, including tetralogy of Fallot and hypospadias. Subfertility and multiple births affect these associations, with multiple births explaining 36% of the relative effect of ART on nonchromosomal birth defects. CONCLUSION Although the risk of birth defects with ART is small, a substantial portion of the relative effect is mediated through multiple births, with subfertility contributing an important role. Future research is needed to determine the impact of newer techniques, such as single embryo transfer, on these risks. Birth Defects Research 109:1144-1153, 2017. © 2017 Wiley Periodicals, Inc.

Abstract
PURPOSE The objective of this study was to evaluate the effect of changing fertility status on perinatal outcomes of singleton siblings, conceived with and without assisted reproductive technology (ART). METHOD A longitudinal cohort study of Massachusetts resident women having two consecutive singleton births during 2004-2010 was performed. Women were classified as ART (A), subfertile (S), or fertile (F) and categorized by their fertility status in each birth as A-A, A-S, S-A, S-S, F-A, F-S, and F-F. Within categories, adjusted mean birthweights, gestations, and birthweight Z scores were estimated with linear generalized estimating equations. Risks of low birthweight (LBW, <2500 g), preterm birth (PTB, <37 weeks), and placental complications were modeled using logistic regression by fertility status as adjusted odds ratios (AORs) and 95 % confidence intervals (CIs). RESULTS Birthweights in second pregnancies averaged 74-155 g higher, except for births to F-A women, who averaged -16 g lower. Most women had a reduction in length of gestation in their second pregnancies, with F-A women having the largest decline (-0.5 weeks). In first birth models, the risks for LBW and placental complications were increased for subfertile (AOR 1.39 [1.07-1.81] and 1.97 [1.33-2.93], respectively) and ART women (AOR 1.58 [1.29-1.93] and 3.40 [2.64-4.37], respectively). Second birth models showed increased risks for ART births of LBW (AOR 3.13 [2.19-4.48]) and placental complications (AOR 2.45 [1.56-3.86]) and greater risks of PTB for both ART (AOR 2.37 [1.74-3.23]) and subfertile women (AOR 1.47 [1.02-2.13]). CONCLUSIONS Declining fertility status, with and without assisted reproductive technology treatment, is associated with increasing risks for adverse outcomes, greatest for women whose fertility status declined the most.

Abstract
OBJECTIVE To assess the validity of outcome data reported to the Society for Assisted Reproductive Technology Clinic Outcome Reporting System (SART CORS) compared with data from vital records and the birth defects registry in Massachusetts. DESIGN Longitudinal cohort. SETTING Not applicable. PARTICIPANT(S) A total of 342,035 live births and fetal deaths from Massachusetts mothers giving birth in the state from July 1, 2004, to December 31, 2008; 9,092 births and fetal deaths were from mothers who had conceived with the use of assisted reproductive technology (ART) and whose cycle data had been reported to the SART CORS. INTERVENTION(S) Not applicable. MAIN OUTCOME MEASURE(S) Percentage agreement between maternal race and ethnicity, delivery outcome (live birth or fetal death), plurality (singleton, twin, or triplet+), delivery date, and singleton birth weight reported in the SART CORS versus vital records; sensitivity and specificity for birth defects among singletons as reported in the SART CORS versus the Massachusetts Birth Defects Monitoring Program (BDMP). RESULT(S) There was >95% agreement between the SART CORS and vital records for fields of maternal race/ethnicity, live birth/fetal death, and plurality; birth outcome date was within 1 day with 94.9% agreement and birth weight was within 100 g with 89.6% agreement. In contrast, sensitivity for report of any birth defect was 38.6%, with a range of 18.4%-50.0%, for specific birth defect categories. CONCLUSION(S) Although most SART CORS outcome fields are accurately reported, birth defect variables showed poor sensitivity compared with the gold standard data from the BDMP. We suggest that reporting of birth defects be discontinued.

Abstract
OBJECTIVE To evaluate pregnancy and birth outcomes by type of infertility treatment received. STUDY DESIGN Assisted reproductive technology (ART) data on women who were both treated and gave birth in Massachusetts were linked to vital records and hospital data. Singleton and twin live births were categorized by ART treatment parameters. Risks for adverse outcomes (pregnancy-induced hypertension [PIH], gestational diabetes [GDM, primary cesarean [CS], prematurity [PTB], low birthweight [LBW], small for gestational age [SGA], large for gestational age [LGA], and birth defects [BD]) were modeled using logistic regression (adjusted odds ratios and 95% confidence intervals), adjusted for parental and treatment factors. GDM and PIH were additionally modeled as adverse outcomes. RESULTS Among the 8,948 pregnancies, risks were significantly higher among twins (PIH 2.58, GDM 1.30, CS 5.83, PTB 11.84, LBW 10.68, SGA 2.17, BD 2.54), donor oocytes (PIH 1.87, CS 1.43, PTB 1.43), ICSI (SGA 1.20), and the presence of > 1 fetal heartbeat at 6 weeks' gestation (2 fetal heartbeats: PTB 1.49, LBW 1.57; 3 fetal heartbeats: PTB 2.07, LBW 2.30, SGA 2.04). Thawed embryos were associated with a higher risk for PIH (1.30) but lower risks for LBW (0.79) and SGA (0.38). GDM was associated with increased risks for CS (1.22), LGA (1.40), and BD (1.50); PIH was associated with risks for CS (1.86), PTB (2.70), and LBW (1.83). CONCLUSION Plurality is the predominant ART treatment risk factor associated with substantial excess morbidity for both mother and infants.

Abstract
OBJECTIVES We examined the prevalence of Early Intervention (EI) enrollment in Massachusetts comparing singleton children conceived via assisted reproductive technology (ART), children born to mothers with indicators of subfertility but no ART (Subfertile), and children born to mothers who had no indicators of subfertility and conceived naturally (Fertile). We assessed the natural direct effect (NDE), the natural indirect effect (NIE) through preterm birth, and the total effect of ART and subfertility on EI enrollment. METHODS We examined maternal and infant characteristics among singleton ART (n = 6447), Subfertile (n = 5515), and Fertile (n = 306,343) groups and characteristics associated with EI enrollment includingpreterm birth using χ(2) statistics (α = 0.05). We estimated the NDE and NIE of the ART-EI enrollment relationship by fitting a model for enrollment, conditional on ART, preterm and the ART-preterm delivery interaction, and covariates. Similar analyses were conducted by using Subfertile as the exposure. RESULTS The NDE indicated that the odds of EI enrollment were 27% higher among the ART group (odds ratioNDE = 1.27; 95% confidence interval (CI): 1.19 ̶ 1.36) and 20% higher among the Subfertilegroup (odds ratioNDE = 1.20; 95% CI: 1.12 ̶ 1.29) compared with the Fertile group, even if the rate of preterm birth is held constant. CONCLUSIONS Singleton children conceived through ART and children of subfertile mothers both have elevated risks of EI enrollment. These findings have implications for clinical providers as they counsel women about child health outcomes associated with ART or subfertility.

Abstract
OBJECTIVE To assess whether risk of severe maternal morbidity at delivery differed for women who conceived using assisted reproductive technology (ART), those with indicators of subfertility but no ART ("subfertile"), and those who had neither ART nor subfertility ("fertile"). METHODS This retrospective cohort study was part of the larger Massachusetts Outcomes Study of Assisted Reproductive Technology. To construct the Massachusetts Outcomes Study of Assisted Reproductive Technology database and identify ART deliveries, we linked ART treatment records to birth certificates and maternal and infant hospitalization records occurring in Massachusetts between 2004 and 2010. An algorithm of International Classification of Diseases, 9th Revision, Clinical Modification diagnosis and procedure codes identified severe maternal morbidity. We used logistic generalized estimating equations to estimate odds of severe maternal morbidity associated with fertility status, adjusting for maternal demographic and health factors and gestational age, stratifying on plurality and method of delivery. RESULTS The prevalence of severe maternal morbidity among this population (n=458,918) was 1.16%. The overall, crude prevalences of severe maternal morbidity among fertile, subfertile, and ART deliveries were 1.09%, 1.44%, and 3.14%, respectively. The most common indicator of severe maternal morbidity was blood transfusion. In multivariable analyses, among singletons, ART was associated with increased odds of severe maternal morbidity compared with both fertile (vaginal: adjusted odds ratio [OR] 2.27, 95% confidence interval [CI] 1.78-2.88; cesarean: adjusted OR 1.67, 95% CI 1.40-1.98, respectively) and subfertile (vaginal: adjusted OR 1.97, 95% CI 1.30-3.00; cesarean: adjusted OR 1.75, 95% CI 1.30-2.35, respectively) deliveries. Among twins, only cesarean ART deliveries had significantly greater severe maternal morbidity compared with cesarean fertile deliveries (adjusted OR 1.48, 95% CI 1.14-1.93). CONCLUSION Women who conceive through ART may have elevated risk of severe maternal morbidity at delivery, largely indicated by blood transfusion, even when compared with a subfertile population. Further research should elucidate mechanisms underlying this risk.

Abstract
OBJECTIVE To evaluate assisted reproductive technology (ART) pregnancy outcomes by infertility diagnosis. STUDY DESIGN ART data on women who were treated and gave birth in Massachusetts were linked to vital records and hospital utilization data. Live births were categorized by 8 mutually exclusive ART diagnoses. Risks of prematurity, low birthweight (LBW), small-for-gestational age (SGA), large-for-gestational age (LGA), pregnancy hypertension, gestational diabetes, prenatal hospitalizations, and primary cesarean delivery were modeled using logistic regression, adjusted for parental characteristics, treatment parameters, and plurality (adjusted odds ratios [AORs] and 95% confidence intervals); the reference group were pregnancies with the diagnosis of malefactor. RESULTS Among the 7,354 singleton and twin pregnancies, there were nonsignificant differences in the risks for LBW, SGA, or LGA. Significantly increased risks included gestational diabetes (ovulation disorders, AOR 1.80, 1.35-2.41), prematurity (ovulation disorders, AOR 1.36, 1.08-1.71; other factors, AOR 1.33, 1.05-1.67), prenatal hospital admissions (endometriosis, tubal and other factors, ovulation disorders, and uterine factors, AORs ranging from 1.66-2.68), and primary cesarean section (uterine factors, AOR 1.96, 1.15-3.36). CONCLUSION Although the infant outcomes of LBW, SGA, and LGA were generally similar across diagnosis groups, specific diagnoses had greater risks for prematurity, gestational diabetes, prenatal hospital utilization, and primary cesarean delivery.

Adverse pregnancy outcomes after in vitro fertilization: effect of number of embryos transferred and plurality at conception. Fertil Steril 2015; 104:79-86. [PMID: 25956368 PMCID: PMC4489987 DOI: 10.1016/j.fertnstert.2015.04.006] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2014] [Revised: 03/24/2015] [Accepted: 04/06/2015] [Indexed: 11/26/2022]
Abstract
OBJECTIVE To evaluate risks for adverse pregnancy outcomes by number of embryos transferred (ET) and fetal heartbeats (FHB) in assisted reproductive technology-conceived singleton live births. DESIGN Longitudinal cohort using cycles reported to the Society for Assisted Reproductive Technology Clinic Outcomes Reporting System between 2004 and 2008 among women who were treated and gave birth in Massachusetts. SETTING Not applicable. PATIENT(S) Assisted reproductive technology data on 6,073 births between 2004 and 2008 were linked to vital records and hospital data. Likelihood of ET ≥3 vs. 1-2, FHB >1 vs. 1, and risks of preterm birth (PTB, <37 weeks' gestation), low birth weight (LBW, <2,500 g), and small-for-gestational-age birth weight (SGA, <10th percentile) with FHB >1 were modeled with binary logistic regression using a backward-stepping algorithm, and presented as adjusted odds ratios (95% confidence intervals). INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) ET ≥3, FHB >1, PTB, LBW, and SGA. RESULT(S) Higher ET was significantly more likely with older maternal age, intracytoplasmic sperm injection, assisted hatching, cleavage-stage embryos, and thawed embryos. The likelihood of FHB >1 with ≥3 ET vs. 1-2 ET was 2.04 (1.68-2.48). Risks of PTB and LBW with FHB >1 were 1.63 (1.27-2.09) and 1.81 (1.36-2.39), respectively; the risk of SGA was not significant. Nulliparity was associated with higher risks of PTB (1.34 [1.12-1.59]), LBW (1.48 [1.20-1.83]), and SGA (2.17 [1.69-2.78]). CONCLUSION(S) Number of embryos transferred was strongly associated with FHBs, with twice the risk of FHB >1 with ≥3 ET vs. 1-2 ET. Increasing FHBs were associated with significantly greater risks for PTB and LBW outcomes.

Abstract
OBJECTIVE To compare the risks for adverse pregnancy and birth outcomes by diagnoses with and without assisted reproductive technology (ART) treatment to non-ART pregnancies in fertile women. DESIGN Historical cohort of Massachusetts vital records linked to ART clinic data from Society for Assisted Reproductive Technology Clinic Outcome Reporting System. SETTING Not applicable. PATIENT(S) Diagnoses included male factor (ART only), endometriosis, ovulation disorders, tubal (ART only), and reproductive inflammatory disorders (non-ART only). Pregnancies resulting in singleton and twin live births from 2004 to 2008 were linked to hospital discharges in women who had ART treatment (n = 3,689), women with no ART treatment in the current pregnancy (n = 4,098), and non-ART pregnancies in fertile women (n = 297,987). INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Risks of gestational diabetes, prenatal hospitalizations, prematurity, low birth weight, and small for gestational age were modeled using multivariate logistic regression with fertile deliveries as the reference group adjusted for maternal age, race/ethnicity, education, chronic hypertension, diabetes mellitus, and plurality (adjusted odds ratios [AORs] and 95% confidence intervals [CIs]). RESULT(S) Risk of prenatal hospital admissions was increased for endometriosis (ART: 1.97, 1.38-2.80; non-ART: 3.34, 2.59-4.31), ovulation disorders (ART: 2.31, 1.81-2.96; non-ART: 2.56, 2.05-3.21), tubal factor (ART: 1.51, 1.14-2.01), and reproductive inflammation (non-ART: 2.79, 2.47-3.15). Gestational diabetes was increased for women with ovulation disorders (ART: 2.17, 1.72-2.73; non-ART: 1.94, 1.52-2.48). Preterm delivery (AORs, 1.24-1.93) and low birth weight (AORs, 1.27-1.60) were increased in all groups except in endometriosis with ART. CONCLUSION(S) The findings indicate substantial excess perinatal morbidities associated with underlying infertility-related diagnoses in both ART-treated and non-ART-treated women.

Abstract
OBJECTIVE To compare on a population basis the birth outcomes of women treated with assisted reproductive technologies (ART), women with indicators of subfertility but without ART, and fertile women. DESIGN Longitudinal cohort study. SETTING Not applicable. PARTICIPANT(S) A total of 334,628 births and fetal deaths to Massachusetts mothers giving birth in a Massachusetts hospital from July 1, 2004, to December 31, 2008, subdivided into three subgroups for comparison: ART 11,271, subfertile 6,609, and fertile 316,748. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Four outcomes-preterm birth, low birth weight, small for gestational age, and perinatal death-were modeled separately for singletons and twins with the use of logistic regression for the primary comparison between ART births and those to the newly created population-based subgroup of births to women with indicators of subfertility but no ART. RESULT(S) For singletons, the risks for both preterm birth and low birth weight were higher for the ART group (adjusted odds ratios [AORs] 1.23 and 1.26, respectively) compared with the subfertile group, and risks in both the ART and the subfertile groups were higher than those among the fertile births group. For twins, the risk of perinatal death was significantly lower among ART births than fertile (AOR 0.55) or subfertile (AOR 0.15) births. CONCLUSION(S) The use of a population-based comparison group of subfertile births without ART demonstrated significantly higher rates of preterm birth and low birth weight in ART singleton births, but these differences are smaller than differences between ART and fertile births. Further refinement of the measurement of subfertile births and examination of the independent risks of subfertile births is warranted.

Abstract
Since inception, the use of assisted reproductive technologies (ART) has been accompanied by ethical, legal, and societal controversies. Guidelines have been developed to address many of these concerns; however, the rapid evolution of ART requires their frequent re-evaluation. We review the literature on ethical and legal aspects of ART, highlighting some of the most visible and challenging topics. Of specific interest are: reporting of ART procedures and outcomes; accessibility to ART procedures; issues related to fertility preservation, preimplantation genetic testing, gamete and embryo donation, and reproductive outcomes after embryo transfer. Improvements in ART reporting are needed nationally and worldwide. Reporting should include outcomes that enable patients to make informed decisions. Improving access to ART and optimizing long-term reproductive outcomes, while taking into account the legal and ethical consequences, are challenges that need to be addressed by the entire community of individuals involved in ART with the assistance of bioethicists, legal counselors, and members of society in general.

Abstract
PURPOSE To compare ages of mothers and of fathers at delivery in couples who are fertile, subfertile, and subfertile treated with assisted reproductive technology (ART) and to characterize birth outcomes in the ART population according to paternal age. METHODS Live birth deliveries in Massachusetts between July, 2004 and December, 2008 were identified from vital records and categorized by maternal fertility status and treatment as ART, subfertile or fertile. The ART births were linked to the Society for Assisted Reproductive Technology Clinic Outcome Reporting System (SART CORS) database to obtain cycle-specific treatment data. Parental ages were obtained from birth certificates. Age of mothers and fathers were compared using ANOVA for continuous measures and χ (2) for categories. Risks of prematurity (<37 weeks), low birthweight (<2,500 g), and low birthweight z-score (small for gestatational age, SGA) were modeled using logistic regression by categories of paternal age as adjusted odds ratios and 95 % CI. RESULTS The study population included 9,092 ART, 6,238 subfertile, and 318,816 fertile deliveries. Paternal ages in the ART and subfertile groups were similar and differed significantly from those of the fertile group. Maternal age in the ART and subfertile groups averaged 5-6 years older than their fertile counterparts and fathers averaged 4-5 years older with twice as many being older than 37. The risks for prematurity, low birthweight and SGA did not increase with increasing paternal age. CONCLUSIONS Fathers in ART- treated and subfertile couples are older than in their fertile counterparts. Older paternal age was not assoicated with increased risk for prematurity, low birthweight, or SGA.

Calculating length of gestation from the Society for Assisted Reproductive Technology Clinic Outcome Reporting System (SART CORS) database versus vital records may alter reported rates of prematurity. Fertil Steril 2014; 101:1315-20. [PMID: 24786746 DOI: 10.1016/j.fertnstert.2014.01.053] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2013] [Revised: 01/14/2014] [Accepted: 01/28/2014] [Indexed: 11/21/2022]
Abstract
OBJECTIVE To compare length of gestation after assisted reproductive technology (ART) as calculated by three methods from the Society for Assisted Reproductive Technology Clinic Outcome Reporting System (SART CORS) and vital records (birth and fetal death) in the Massachusetts Pregnancy to Early Life Longitudinal Data System (PELL). DESIGN Historical cohort study. SETTING Database linkage analysis. PATIENT(S) Live or stillborn deliveries. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) ART deliveries were linked to live birth or fetal death certificates. Length of gestation in 7,171 deliveries from fresh autologous ART cycles (2004-2008) was calculated and compared with that of SART CORS with the use of methods: M1 = outcome date - cycle start date; M2 = outcome date - transfer date + 17 days; and M3 = outcome date - transfer date + 14 days + day of transfer. Generalized estimating equation models were used to compare methods. RESULT(S) Singleton and multiple deliveries were included. Overall prematurity (delivery <37 weeks) varied by method of calculation: M1 29.1%; M2 25.6%; M3 25.2%; and PELL 27.2%. The SART methods, M1-M3, varied from those of PELL by ≥ 3 days in >45% of deliveries and by more than 1 week in >22% of deliveries. Each method differed from each other. CONCLUSION(S) Estimates of preterm birth in ART vary depending on source of data and method of calculation. Some estimates may overestimate preterm birth rates for ART conceptions.
