Abstract
OBJECTIVES To compare the differences in the prevalence of birth defects among offspring conceived by assisted reproductive technology (ART) and conceived spontaneously (non-ART), and assess the contribution of ART to birth defects. DESIGN A population-based retrospective cohort study. SETTING Beijing. PARTICIPANTS Pregnant women whose expected date of childbirth was verified as occurring between October 2014 and September 2015, and were registered on the Beijing Maternal and Child Health Information Network System, were the recorded pregnancy outcomes. 2699 ART offspring and 191 368 non-ART offspring (live births, stillbirths and medical terminations) were included in our study. INTERVENTIONS None. OUTCOME MEASURES Risk ratios (RR) for birth defects were calculated among ART conceptions and non-ART conceptions with confounding factors by using logistic regression models. RESULTS 194 067 offspring were included in the present study, and 2699 (1.4%) were conceived using ART. Among all the births, the prevalence of any birth defect in the ART offspring (5.5%) was significantly higher than in the non-ART offspring (3.8%) (crude RR, 1.49, 95% CI 1.26 to 1.76). After adjusting for confounding factors, ART use was still associated with an increased risk of any birth defect (5.4% vs 3.5% in ART and non-ART group, adjusted RR (aRR), 1.43, 95% CI 1.08 to 1.90), especially for chromosomal abnormalities (0.5% vs 0.2% in ART and non-ART group, aRR, 3.11, 95% CI 1.28 to 7.58), in singleton births to mothers <35 years. Circulatory system malformations and musculoskeletal system malformations were observed to have a non-significant increase in offspring conceived by ART. However, the associations between ART and birth defects were not detected in multiple births or mothers ≥35 years. CONCLUSIONS This study confirmed a small but significant association between ART and birth defects. However, the risk tends to be non-significant under the conditions of advanced maternal age or multiple pregnancies.

Abstract
Background: Assisted reproductive technologies (ARTs) have made great progress. However, whether tube baby born after ART were at an increased risk of birth defects is not clear.Objective: To assess whether the ART increases the risk of birth defects in children born after ART.Search strategy: Medline, Google Scholar, and the Cochrane Library were searched.Selection criteria: Clinical trials that evaluate the risk of birth defect in children born after in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) and natural conceptions (NC) were included. The primary outcome was the prevalence of birth defects.Data collection and analysis: The relative risk was used as the summary measure with random effects model. We assessed heterogeneity between studies using the I2 index.Main results: Totally 46 studies were included. The pooled relative risk (RR) estimated suggested there was an increased risk of birth defects in ART compared with the NC group (RR: 1.40; 95% CI 1.31-1.49). Twenty and fifteen studies were included to compare the risk of birth defects between NC and IVF/ICSI, respectively. The results indicated that both IVF and ICSI increase the risk of birth defects (IVF: RR 1.25; 95% CI 1.12-1.40; ICSI: RR 1.29; 95% CI 1.14-1.45). When subgroup according to plurality, 22 studies assessed the risk of birth defects after ART or NC in singletons and 15 studies evaluated the risk of birth defects in twins. The pooled RRs were 1.41 (95% CI 1.30-1.52) and 1.18 (95% CI 0.98-1.42), respectively.Conclusions: Children born after ART were at an increased risk of birth defects compared with NC. There was no difference in birth defects risk between ART twins and NC twins.

Abstract
In medicine, safety and efficacy are the two pillars on which the implementation of novel treatments rest. To protect the patient from unnecessary or unsafe treatments, usually, a stringent path of (pre) clinical testing is followed before a treatment is introduced into routine patient care. However, in reproductive medicine several techniques have been clinically introduced without elaborate preclinical studies. Moreover, novel reproductive techniques may harbor safety risks not only for the patients undergoing treatment, but also for the offspring conceived through these techniques. If preclinical (animal) studies were performed, efficacy and functionality the upper hand. When a new medically assisted reproduction (MAR) treatment was proven effective (i.e. if it resulted in live birth) the treatment was often rapidly implemented in the clinic. For IVF, the first study on the long-term health of IVF children was published a decade after its clinical implementation. In more recent years, prospective follow-up studies have been conducted that provided the opportunity to study the health of large groups of children derived from different reproductive techniques. Although such studies have indicated differences between children conceived through MAR and children conceived naturally, results are often difficult to interpret due to the observational nature of these studies (and the associated risk of confounding factors, e.g. subfertility of the parents), differences in definitions of clinical outcome measures, lack of uniformity in assessment protocols and heterogeneity of the underlying reasons for fertility treatment. With more novel MARs waiting at the horizon, there is a need for a framework on how to assess safety of novel reproductive techniques in a preclinical (animal) setting before they are clinically implemented. In this article, we provide a blueprint for preclinical testing of safety and health of offspring generated by novel MARs using a mouse model involving an array of tests that comprise the entire lifespan. We urge scientists to perform the proposed extensive preclinical tests for novel reproductive techniques with the goal to acquire knowledge on efficacy and the possible health effects of to-be implemented reproductive techniques to safeguard quality of novel MARs.

Abstract
OBJECTIVES We assessed the association between assisted reproductive technology (ART) and diagnosed autistic disorder in a population-based sample of California births. METHODS We performed an observational cohort study using linked records from the California Birth Master Files for 1997 through 2007, the California Department of Developmental Services autism caseload for 1997 through 2011, and the Centers for Disease Control and Prevention's National ART Surveillance System for live births in 1997 through 2007. Participants were all 5 926 251 live births, including 48 865 ART-originated infants and 32 922 cases of autism diagnosed by the Department of Developmental Services. We compared births originated using ART with births originated without ART for incidence of autism. RESULTS In the full population, the incidence of diagnosed autism was twice as high for ART as non-ART births. The association was diminished by excluding mothers unlikely to use ART; adjustment for demographic and adverse prenatal and perinatal outcomes reduced the association substantially, although statistical significance persisted for mothers aged 20 to 34 years. CONCLUSIONS The association between ART and autism is primarily explained by adverse prenatal and perinatal outcomes and multiple births.

Abstract
With an ever-expanding population of children born after in-vitro fertilisation (IVF), the widespread use of assisted reproductive techniques (ART) has placed a great emphasis on the need to study their long-term outcomes. Indeed, there has been concern that mechanisms used in ART may have a detrimental effect on the neurocognitive development of these children. Reassuringly, most neurocognitive and motor development studies using various assessment scales have generally found no differences between intracytoplasmic sperm injection, IVF and naturally conceived children. Only a few studies have reported concerns. In terms of predictors of intelligence in children, ART appears to have a minimal effect in comparison to birth weight, gestational age, socio-economic status, and parental educational levels. Nevertheless, further research of higher methodological quality in children beyond pre-school age and on newer ART procedures is needed.

Abstract
Assisted reproductive technologies (ART) using in-vitro fertilization (IVF) account for ∼1% of births in the USA and as much as 3-4% in Europe or Australia. Initially studies involved infants prospectively examined in an early cohort of US births, with salutary results. Later studies began to show the frequency of birth defects to be increased. In meta-analysis, odds ratio was >1.0, with the 95% confidence limit not extending to <1.0. Although ART are associated with a 30% increase in birth defects; subfertile couples achieving pregnancy without ART show a 20% increase. It thus appears that the increase in birth defects is due less, if at all, to ART protocols per se than to the biological perturbations that generated the infertility that necessitated ART to achieve pregnancy. There is consensus that traditional IVF and intracytoplasmic sperm injection (ICSI)/IVF show the same overall risk notwithstanding increased sex chromosome abnormalities in both procedures and increased hypospadias in ICSI. No other organ system seems disproportionately affected. There is no additive risk in ART twins compared with non-ART twins, nor in embryos having been cryopreserved. The increased risk observed had not appeared to dissuade couples from attempting to have their own children.

Abstract
OBJECTIVE To systematically review the existing literature on neurodevelopmental outcomes in children born after medically assisted reproduction compared with those of children born after spontaneous conception. DESIGN Systematic review. SETTING Not applicable. PATIENT(S) Children born after medically assisted reproduction vs. reference groups of spontaneously conceived children. INTERVENTION(S) Data were reviewed from worldwide published articles, without restrictions as to publication year or language. A total of 80 studies included between 31 and 2,446,044 children. MAIN OUTCOME MEASURE(S) Child neurodevelopmental outcomes categorized as cognitive, behavioral, emotional or psychomotor development, or diagnoses of mental disorders. RESULT(S) For infants, studies on psychomotor development showed no deficits, but few investigated cognitive or behavioral development. Studies on toddlers generally reported normal cognitive, behavioral, socio-emotional, and psychomotor development. For children in middle childhood, development seems comparable in children born after assisted reproduction and controls, although fewer studies have been conducted with follow-up to this age. Very few studies have assessed neurodevelopmental outcomes among teens, and the results are inconclusive. Studies investigating the risk of diagnoses of mental disorders are generally large, with long follow-up, but the results are inconsistent. CONCLUSION(S) It may tentatively be concluded that the neurodevelopment of children born after fertility treatment is overall comparable to that in children born after spontaneous conception.

OBJECTIVE To conduct a meta-analysis of studies assessing the effect of IVF and intracytoplasmic sperm injection (ICSI) on birth defects. DESIGN Meta-analysis. SETTING Centers for reproductive care. PATIENT(S) Patients treated by IVF and/or ICSI. INTERVENTION(S) We identified all studies published by September 2011 with data related to birth defects in children conceived by IVF and/or ICSI compared with spontaneously conceived children, or birth defects in the children conceived by IVF compared with those by ICSI. Risk ratios from individual studies were pooled with the fixed and random effect models. MAIN OUTCOME MEASURE(S) Risk of birth defects in children conceived by IVF and/or ICSI. RESULT(S) Of 925 studies reviewed for eligibility, 802 were excluded after screening titles and abstracts, 67 were excluded for duplicated data, data unavailable, or inappropriate control group, 56 were included in the final analysis. Among the 56 studies, 46 studies had data on birth defects in children conceived by IVF and/or ICSI (124,468) compared with spontaneously conceived children. These studies provided a pooled risk estimation of 1.37 (95% confidence interval [CI]: 1.26-1.48), which is also evident in subgroup analysis. In addition, 24 studies had data on birth defects in children conceived by IVF (46,890) compared with those by ICSI (27,754), which provided an overall no risk difference. CONCLUSION(S) Children conceived by IVF and/or ICSI are at significantly increased risk for birth defects, and there is no risk difference between children conceived by IVF and/or ICSI.

Abstract
OBJECTIVE To determine if pregnancies conceived through infertility treatment are at increased risk of cytogenetic abnormalities in the late first trimester compared with spontaneously conceived pregnancies, or if there is increased risk when comparing less invasive infertility treatment (in vivo group) to in vitro fertilization (in vitro group). DESIGN Retrospective case-controlled study. SETTING University hospital. PATIENT(S) A total of 1,606 women who spontaneously conceived and 559 women who conceived through infertility treatment undergoing chorionic villus sampling (CVS). INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Cytogenetic abnormalities diagnosed by CVS. RESULT(S) No difference in cytogenetic abnormalities was found when comparing spontaneously conceived pregnancies to those conceived through infertility treatment (7.0% versus 5.4%). We also found no difference in the prevalence of cytogenetic abnormalities when comparing in vivo and in vitro fertilization subgroups (4.7% versus 5.8%). Finally, no difference was found when comparing the prevalence of different types of cytogenetic abnormalities between groups. CONCLUSION(S) Infertility treatment does not increase the risk of carrying a cytogenetically abnormal fetus in the late first trimester, nor does it increase the preponderance for any specific type of abnormality.

Abstract
Assisted reproductive therapies (ART), namely in vitro fertilisation (IVF) and intracytoplasmic sperm injection (ICSI), have become widely used in the treatment of human infertility. Children conceived using ART represent a substantial proportion of the population. Follow-up of these children is necessary in order to evaluate the risks of infertility treatment upon subsequently conceived offspring. In recent years there has been considerable work in this field. This review summarises current evidence regarding the health of children conceived following ART, encompassing neonatal outcomes, the risk of congenital malformations, neurodevelopmental outcome, physical health, psychosocial well being, and the risk of cancer. The main risks for the future well being of ART children remain multiple pregnancies and low birth weight. Evidence regarding the outcome of singletons born at term following ART is generally reassuring. It is essential that follow-up of ART children continues as they progress through adolescence into adulthood.

Abstract
The aim of this study was to examine the school functioning of 8- to 18-year-old children born after in vitro fertilization (IVF). We compared 233 children born after IVF to 233 matched control children born spontaneously from parents with fertility problems on measures of education level, general cognitive ability, school performance (need for extra help, repeating a grade, special education), and rates of learning and developmental disorders. No differences were found between IVF and control children on these measures of school functioning. More than 60% of adolescents at secondary school attended high academic levels (with access to high school or university). We conclude that children and adolescents born after IVF show good academic achievement and general cognitive ability. They do not experience any more educational limitations than the naturally conceived children and adolescents of the control group. The tendency of reassuring school functioning already found in younger IVF children has been shown to continue at secondary school age.

Abstract
OBJECTIVE To examine whether sufficient research has been done and definite conclusions can be drawn on the psychological outcome of children born after in vitro fertilization (IVF), a review was performed of studies on early development, cognition, and psychosocial well-being in IVF children. METHOD PubMed and PsycINFO databases were searched. All English language studies up to 2006 addressing these topics were included. RESULTS After 25 years of follow-up studies on the development, school outcome, and psychosocial well-being of IVF children, it seems that mental and psychomotor development during the first year and preschool years and cognitive development at 5 years are not deviant. At 6-12 years of age, no differences were observed in cognitive and school performance compared with naturally conceived children; however, the number of studies in this age group is limited. No studies are available that evaluate cognitive aspects and school performance at secondary school age. Overall, positive parent-child relationships were reported in IVF families. In some studies, IVF mothers report more difficulties with their child's behavior only in the child's first year. With regard to the children's psychosocial well-being, no differences were found up to the age of 8 years. Although after that age, slight indications for some socioemotional and behavioral problems emerged, a large study on the onset of puberty reported that psychosocial functioning was reassuring. Data for adolescents are still lacking. CONCLUSION Psychological functioning of those born after IVF is reassuring. However, follow-up should be continued and studies should focus on specific cognitive abilities, school performance, and emotional functioning in adolescence.

Abstract
OBJECTIVE To evaluate growth and development of children born after IVF treatment. DESIGN Literature review. CONCLUSION(S) At present there is substantial evidence that children born after IVF are at increased risk for adverse perinatal outcome, congenital malformations, and rare epigenetic defects. It is still unclear whether observed health problems originate from the IVF procedure itself or the underlying subfertility problems of the parents. Current follow-up studies regarding postnatal growth and morbidity rates are scarce with conflicting results and other areas of long-term research in children born after IVF are still in its infancy. The importance of the worldwide continuing monitoring of children born after IVF to investigate potential long-term consequences including the development of cardiovascular diseases is therefore highlighted.

Abstract
AIMS The objective of this study is to evaluate the physical and mental development of infants born on in-vitro maturation (IVM) programs. STUDY DESIGN We compare 21 IVM children as study group and 21 non-IVM children as control group. We performed a general physical examination for malformations, neurological examination, developmental examination (Bayley Scales) on the IVM group and the non-IVM group. RESULTS We found all the children with normal karyotype and without major malformation in both IVM and non-IVM groups. The mean Mental Development Index scores for IVM subjects and the comparison group were 92.71+/-10.47 and 97.19+/-8.88, respectively (p=0.074). The mean Psychomotor Development Index scores were 96.67+/-8.91 and 96.19+/-7.05, respectively (p=0.817). CONCLUSIONS This is the first study designed to evaluate the physical growth and developmental indices of IVM children with combinational priming protocol of FSH and hCG. Our results suggest that IVM children didn't show developmental delay during infancy and early childhood.

Abstract
Long-term follow-up studies on the health and the development of children conceived by assisted reproduction (ART) are mandatory to assess the safety of ART. Meanwhile, different aspects of health of these children have been studied. To put these results together, we performed a systematic review of these publications. A Pubmed search and a hand-search of the abstract books from the annual meeting of the European Society of Human Reproduction and Embryology and the American Society of Reproductive Medicine were performed for controlled studies on the developmental outcome of children after ART, which include a matching for plurality of gestation. Regarding general health, growth, mental and psychomotor development IVF children do not differ from spontaneously conceived (SC) children. An increased need for surgical interventions may be due to an increase in the malformation rate. However, a lower birth weight and lower gestational age compared to matched controls may contribute to some health problems observed. The increased risk of neurological problems found in some large registry-based studies can partly be explained by the higher frequency of twins born, by low birth weight, and by low gestational age also found in singletons. But an effect of IVF, the parents' infertility or other factors not adjusted for in the studies cannot be excluded. In addition to this reporting bias caused by concerned parents cannot be excluded, either. To conclude, children born after assisted reproductive techniques are generally healthy and are developmentally similar to children born after SC. However, low birth weight and prematurity contributes to health care problems. An increase of neurological problems by IVF cannot be excluded. Further prospective studies on the neurological outcome are needed.

Abstract
Although there is increasing evidence to link couples with infertility undergoing all assisted reproductive technologies, particularly intracytoplasmic sperm injection (ICSI), and congenital abnormalities, the reasons remain unclear. Much evidence suggests that infertility itself might be a risk factor, and further long-term follow-up studies involving different possible control groups will help determine whether these abnormalities are directly related to treatment.

Abstract
PURPOSE To investigate visual function and ocular morphology in children born after intracytoplasmic sperm injection (ICSI) and compare them with visual function and ocular morphology in matched children born after spontaneous conception. METHODS A total of 137 children born after ICSI and 159 control children were examined at the age of 5 years in a blinded study. The two groups were matched for age, gender and maternal age. The children underwent a detailed ophthalmological investigation by an ophthalmologist and an orthoptist. RESULTS A total of 90.4% of the ICSI children had a visual acuity (VA) in the better eye of >or= 0.8, compared with 93.7% of the controls (NS). No significant differences were found between ICSI children and controls with regard to hyperopia, myopia, astigmatism, heterotropia, stereoscopic vision and convergence. One child with Goldenhar syndrome and one with Marcus Gunn syndrome were observed in the ICSI group. One child in the ICSI group was treated for retinopathy of prematurity. CONCLUSION In this limited study group, no significant differences in visual function and/or ocular morphology were found between children born after ICSI and matched control children at the age of 5 years.

Abstract
OBJECTIVE To determine the risk of major birth defects in cohorts of children conceived through IVF or through IUI as compared with naturally conceived children. DESIGN Retrospective cohort study. SETTING Academic medical center. PATIENT(S) Children conceived by IVF or IUI at the University of Iowa from 1989 through 2002, compared with a matched cohort of naturally conceived children. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Outcome data were obtained from Iowa state birth and fetal death certificates and from the Iowa Birth Defects Registry. RESULT(S) Ninety of 1,462 IVF-conceived children (6.2%) and 17 of 343 IUI-conceived children (5.0%) had a major birth defect, compared with 369 of 8,422 naturally conceived children (4.4%). The adjusted odds ratio of a major birth defect in all IVF-conceived children was 1.30 (95% confidence interval [CI] 1.00-1.67) and 1.11 (95% CI 0.67-1.84) for IUI-conceived children. The birth defect rate was increased after IVF when the analysis was limited to term singletons. Cardiovascular and musculoskeletal defects and known birth defect syndromes were increased after IVF. Among IVF-conceived children, there was no difference in birth defect rates after intracytoplasmic sperm injection (ICSI) or after transfer of cryopreserved embryos. CONCLUSION(S) Infants conceived through IVF have a slightly higher rate of major birth defects. More birth defects are noted among children born to infertile couples treated with IUI, although this difference is not statistically significant. Larger studies of infants conceived by infertile couples after all types of infertility treatment are needed to definitively determine whether the increased risk of birth defects is secondary to problems inherent in the infertile couple and/or factors associated with some aspect of the treatment.

Abstract
OBJECTIVE Primary outcome was to compare neurodevelopmental outcome at two years in intracytoplasmic sperm injection (ICSI) conceived children versus matched controls. Secondary outcome was to determine incidence of major congenital malformations and study perinatal outcome. DESIGN Prospective cohort study. SETTING Tertiary care perinatal centre over a period of 13 months. POPULATION Seventy-six ICSI conceived children and 261 matched controls selected by matching for maternal age, sex, date of delivery, race, plurality and parity. METHODS Mental Development Index (MDI) and Psychometric Development Index (PDI) of the Bayley's Scale of Development (BSID-II) and Vineland Adaptive Behaviour Scale (VABS) were used to assess the neurodevelopmental and functional outcome. The congenital malformations were classified according to ICD-9 code. MAIN OUTCOME MEASURES Primary outcome measure--neurodevelopmental and functional outcomes. Secondary outcome measure--congenital malformations and perinatal outcomes. RESULTS Neurodevelopmental and functional outcome were comparable in both groups. The mean MDI score was 92 [16] versus 90 [14] in the study and control groups respectively. Fourteen (18.4%) in the ICSI group had MDI <85 compared with 87 (33%) controls (P= 0.002). On linear regression the MDI was independently affected by plurality (P= 0.001), maternal education and socio-economic status (P= 0.01). The study group had a lower gestation (36 [3] vs 37.1 [2] weeks; P= 0.005) and a higher incidence of prematurity <34 weeks [19 (25%)] vs [31 (12%)] P= 0.012]. Six (7.9%) of the ICSI babies and seven (2.7%) of the controls had a major congenital malformation (P= 0.05). CONCLUSIONS Children born by ICSI pregnancies did not have an adverse neurodevelopmental outcome. The incidence of major congenital malformations in ICSI needs further evaluation.

Abstract
OBJECTIVE This study evaluated the impact of changes in perinatal management on neurodevelopmental impairment (NDI) at 18 to 22 months' corrected age of low gestation (22-26 weeks) and higher gestation (27-32 weeks) extremely low birth weight infants (401-1000 g birth weight) who were cared for in the National Institute of Child Health and Human Development Neonatal Research Network during 3 epochs (1993-1994, 1995-1996, and 1997-1998). It was hypothesized that outcomes would improve over the 3 epochs. METHODS A multicenter cohort study was conducted of the outcomes of 3785 infants with assessments at 18 to 22 months' corrected age. Regression analyses were completed to evaluate for epoch effects, gestational age effects, and time plus gestational age interaction. Regression analyses were also performed to identify the independent associations of epoch and 4 study perinatal interventions: antenatal steroids (yes, no), high-frequency ventilation (yes, no), number of days to regain birth weight as a marker of nutritional intake, and postnatal steroids for treatment of bronchopulmonary dysplasia (yes, no) with outcomes. RESULTS Survival improved for both the low (55%-61%) and higher (82%-86%) gestational age groups during the 3 epochs. Regression analyses indicated that the decreased risk for adverse outcome was significantly lower in epoch 2 compared with epoch 1 with decreased rates of low Bayley Mental Development Index (MDI) and neurodevelopmental impairment (NDI). Antenatal steroids were associated with decreased risk for moderate to severe cerebral palsy (CP) and low Bayley Psychomotor Development Index. High-frequency ventilation was associated with a low Bayley MDI and NDI, and postnatal steroids were associated with moderate to severe CP, any CP, low Bayley MDI, low Bayley Psychomotor Development Index, and increased NDI. CONCLUSION Survival of extremely low birth weight infants improved between 1993 and 1998. Although some outcomes remained unchanged, the rates of low Bayley MDI scores and NDI improved. Antenatal steroid administration was the only study intervention associated with improved outcomes.

Abstract
Since the 1970s, the national twin birth rates have been increasing worldwide. Apart from the increasing childbearing age, the main cause is the use of assisted reproductive technologies (ART). To explore the overall consequences of dual embryo transfer (DET), the literature has been reviewed systematically regarding short- and long-term outcomes of IVF/ICSI twin pregnancies i.e. pregnancy complications, maternal risks, obstetric outcome and long-term morbidity including neurological sequelae, cognitive development and family implications. Another consequence of DET is vanishing twins, which seems to be a possible cause of adverse outcome in IVF singletons. The sparse literature on vanishing twins in IVF pregnancies and the influence on the surviving co-twin were also addressed. Finally, to determine the effects of implementing elective single embryo transfer (eSET), trials concerning eSET versus DET were analysed. In the light of the steadily increasing twin birth rates and the findings in this overview, where IVF/ICSI twins carry adverse outcome, it should be emphasized that the major obstacle in IVF remains the high twin birth rate. Furthermore vanishing twins account for another hazard of DET. These problems can be resolved by implementing eSET, diminishing the twin birth rate without affecting the overall goal of achieving a healthy infant.

Abstract
BACKGROUND The risk of birth defects in infants born following assisted reproductive technology (ART) treatment is a controversial question. Most publications examining the prevalence of birth defects in ICSI and IVF infants compared to spontaneously conceived infants have serious methodological limitations; despite this, most researchers have concluded that there is no increased risk. METHODS We carried out a systematic review to identify all papers published by March 2003 with data relating to the prevalence of birth defects in infants conceived following IVF and/or ICSI compared with spontaneously conceived infants. Independent expert reviewers used criteria defined a priori to determine whether studies were suitable for inclusion in a meta-analysis. Fixed effects meta-analysis was performed for all studies and reviewer-selected studies. RESULTS Twenty-five studies were identified for review. Two-thirds of these showed a 25% or greater increased risk of birth defects in ART infants. The results of meta-analyses of the seven reviewer-selected studies and of all 25 studies suggest a statistically significant 30-40% increased risk of birth defects associated with ART. CONCLUSIONS Pooled results from all suitable published studies suggest that children born following ART are at increased risk of birth defects compared with spontaneous conceptions. This information should be made available to couples seeking ART treatment.

Abstract
PURPOSE OF REVIEW This review addresses the question of whether there is evidence of an increased risk of birth defects in children born following assisted reproductive technologies compared with spontaneously conceived children. RECENT FINDINGS Three recent studies added relatively little new information given their modest size (56-472 assisted reproductive technology children). We therefore considered all published papers that compared birth defects in children born following assisted reproductive technologies with those in children born following spontaneous conception. Overall, only six of the 26 relevant papers concluded there was an increased risk of birth defects following assisted reproductive technologies. The interpretation of many studies was based on statistical significance testing alone. When results showed a greater proportion of defects in the assisted reproductive technology group compared with the spontaneous group, but the results were not statistically significant, this was often interpreted as showing no increase in risk, rather than an increase in risk that may have been due to chance. The vast majority of individual studies were too small to have sufficient power to detect, as statistically significant, clinically relevant results. We found that although only eight (30%) of the studies had statistically significant results, 24 (89%) had an odds ratio estimate comparing assisted reproductive technology with spontaneously conceived children of over 1.0; 19 (70%) had an estimate of 1.20 or greater; and 14 (52%) had an estimate of 1.5 or greater. SUMMARY Current evidence suggests there is an elevated risk of birth defects in children born following assisted reproductive technologies. Whilst others may disagree with our interpretation, one certainly cannot exclude this possibility on the basis of the current evidence.

Abstract
BACKGROUND The birth of the first 'test-tube' baby in 1978 has led to the creation of family types that would not otherwise have existed. METHODS This paper examines research on the psychological outcomes for parents and children in assisted reproduction families with particular attention to the issues and concerns that have been raised by creating families in this way. RESULTS Parents of children conceived by assisted reproduction appear to have good relationships with their children, even in families where one parent lacks a genetic link with the child. With respect to the children themselves, there is no evidence of cognitive impairment in singleton children born at full term as a result of assisted reproduction procedures, although the findings regarding the cognitive development of intracytoplasmic sperm injection (ICSI) children are currently unclear. In relation to socioemotional development, assisted reproduction children appear to be functioning well. CONCLUSIONS Few studies have included children at adolescence or beyond, and little is known about the consequences of conception by assisted reproduction from the perspective of the individuals concerned. In addition, there are some types of assisted reproduction family, such as families created through a surrogacy arrangement or through embryo donation, about whom little is known at all. Although existing knowledge about the impact of assisted reproduction for parenting and child development does not give undue cause for concern, there remain a number of unanswered questions in relation to children born in this way.

Abstract
BACKGROUND Findings are presented of the second phase of a European longitudinal study of families created by assisted reproduction. The present investigation reports on data obtained during the child's transition to adolescence. METHODS A total of 102 IVF families, 94 donor insemination (DI) families, 102 adoptive families, and 102 families with a naturally conceived child were compared on standardized interview and questionnaire measures of parenting and children's psychological well-being. RESULTS The assisted reproduction families were similar to the adoptive and natural conception families for many of the measures of the quality of parent-child relationships. To the extent that differences were found between the assisted reproduction families and the other family types, these reflected mainly more positive functioning among the assisted reproduction families, with the possible exception of the overinvolvement with their children of a small proportion of assisted reproduction mothers and fathers. The assisted reproduction children were functioning well and did not differ from the adoptive or naturally conceived children on any of the measures of psychological adjustment. However, only 8.6% had been told about their genetic origins. CONCLUSIONS IVF and DI families with an early adolescent child appear to be functioning well.

Abstract
In vitro fertilization (IVF) is a well established and effective method for the treatment of infertility, but there is concern about the health of children born as a result of this procedure. The introduction of new technologies, such as intracytoplasmic sperm injection (ICSI), has increased concern that the offspring from such techniques may be at increased risk, particularly of malformations. Studies on obstetric and neonatal outcome and early infant development after IVF obtained from a Medline search were reviewed. Children born after IVF had a considerably higher risk of being born pre-term and with a lower birth weight than children conceived naturally. A high incidence of multiple births and maternal characteristics were the main factors responsible for the increase in adverse outcome. Novel strategies in assisted reproduction, including the development of single embryo transfer regimens and avoidance of multiple births, are required. There is also a need for further developmental follow-up of children born after assisted conception, especially those born after ICSI.

Abstract
The presence of congenital malformations in infants born after IVF was studied from a register consisting of practically all infants born in Sweden after IVF, 1982--1997 (n = 9111). A further 64 infants were studied using only medical records. It is a nation-wide study and has a population-based control group (n = 1,690,577) and relevant potential confounders have been taken into account. There was an excess of congenital malformations registered in the Medical Birth Registry (n = 516, odds ratio = 1.47) but this excess disappeared when confounders were taken into consideration: year of birth, maternal age, parity, and period of unwanted childlessness (odds ratio = 0.89). For some specific conditions, an approximately 3-fold excess risk was seen: neural tube defects, alimentary atresia, omphalocele, and hypospadias (after intracytoplasmatic sperm injection). No excess risk for hypospadias was seen after standard IVF. Various explanations for these findings are discussed. It is postulated that the excess risk for alimentary atresia, like the excess risk for monozygotic twinning after IVF, is a direct consequence of the IVF procedure. The excess risk for hypospadias after ICSI may be related to paternal subfertility with a genetic background. The absolute risk for a congenital malformation in association with IVF is small.

Abstract
Controlled ovarian hyperstimulation could lead to opposing effects on thyroid function. Therefore, in a prospective study of 65 women undergoing controlled ovarian hyperstimulation, thyroid hormones, T4-binding globulin, TPO antibodies, gonadotropins, estradiol, and PRL were measured before and after controlled ovarian hyperstimulation. After ovarian stimulation (mean +/- SE of mean): free T4 decreased, 14.4 +/- 0.2 vs. 12.9 +/- 0.2 pmol/L (P < 0.0001); thyroid-stimulating hormone increased, 2.3 +/- 0.3 vs. 3.0 +/- 0.4 mU/L (P < 0.0001); T4-binding globulin increased, 25.2 +/- 0.7 vs. 33.9 +/- 0.9 mg/L (P < 0.0001); total T4 increased, 98.1 +/- 2.3 vs. 114.6 +/- 2.5 nmol/L (P < 0.0001); total T3 increased, 2.0 +/- 0.04 vs. 2.3 +/- 0.07 nmol/L (P < 0.0001); TPO antibodies decreased, 370 +/- 233 U/mL vs. 355 +/- 224 U/mL (P < 0.0001); LH decreased, 8.1 +/- 1.1 vs. 0.4 +/-0.1 U/L (P < 0.0001); FSH did not change, 6.5 +/- 0.6 vs. 7.9 +/- 0.9 U/L (P = 0.08); human CG increased, <2 +/- 0.0 vs. 195 +/- 16 U/L (P < 0.0001); estradiol increased, 359.3 +/- 25.9 pmol/L vs. 3491.8 +/-298.3 pmol/L (P < 0.0001); and PRL increased, 0.23 +/- 0.02 vs. 0.95 +/- 0.06 U/L (P < 0.0001). Because low maternal free T4 and elevated maternal thyroid-stimulating hormone levels during early gestation have been reported to be associated with impaired psychomotor development in the offspring, our findings indicate the need for additional studies in the children of women who where exposed to high levels of estrogens around the time of conception.

Abstract
Our objective was to evaluate long-term outcome of children born after inadvertent administration of a gonadotrophin-releasing hormone agonist (GnRHa) in early pregnancy, compared to a control group of children born to matched women undergoing in-vitro fertilization and children born after spontaneous pregnancies. Six children from six pregnancies, exposed to a long-acting gonadotrophin agonist, comprised the study group and 20 children were included in the control groups. Pre-, peri- and postnatal data were collected and the children were followed and examined at a mean age of 7.8 +/- 2.0 years. All children underwent physical and neurological examination, and psychological tests. In the study group, one child was born with a major congenital malformation (cleft palate), and four children subsequently demonstrated neurodevelopmental abnormalities, including epileptic disorder (n = 1), attention deficit hyperactivity disorder (n = 3), motor difficulties (n = 3) and speech difficulties (n = 1). In the control groups, one child had attention deficit hyperactivity disorder. This observation of neurodevelopmental abnormalities in four of six children in the study group justifies the need for long-term follow-up of more children previously exposed to gonadotrophin-releasing hormone agonist.

Abstract
Subzonal injection of spermatozoa (SUZI) was one of the first micromanipulation techniques efficient in treating male factor infertility and unexplained in-vitro fertilization failures. The aim of this retrospective study was to evaluate the in-vitro development of embryos conceived by SUZI, the obstetric outcome, the rate of congenital malformations and subsequent follow-up in children. Fifty-five pregnancies were obtained between 1991 and 1994 (54 after fresh embryos were transferred and one after cryopreserved embryos were transferred). Among the 50 clinical pregnancies, there were seven miscarriages (14%) and two ectopic pregnancies (4%). Among the 41 resulting evolutive pregnancies, the discovery of one anencephaly led to a medical abortion. Forty deliveries including six twin pregnancies occurred, leading to the births of 45 live neonates and one stillbirth. The gender distribution of the offspring included 17 males and 29 females (ratio 0.59:1). Birth weight, length and head circumference were within the expected ranges. Two children presented a malformation: the first one had one thumb with congenital shelf and the second a polymalformative neurological syndrome. Growth curves were normal for all these children except one (weight above the 2 SD curve). Medical follow-up detected no pathological features in these children apart from a physical disability in one girl. In this small series a 4.2% rate of malformation was observed, particularly affecting the neural tube, in SUZI offspring. However, no firm conclusions can be drawn since the study was carried out on a small cohort. SUZI is no longer performed but these observations suggest that it is necessary to collect extensive data about children conceived by microfertilization.

Abstract
This study assessed the behavioural and psychological profiles of children conceived by in-vitro fertilization (IVF) who are now at school age. A total of 743 IVF children born at one institution and now of school age, over 4 years old, were surveyed with Achenbach questionnaires. Follow-up telephone interviews were conducted with non-responders. The results from the study group were compared to the questionnaire control group using one-tailed t-test with statistical significance set less than 0.05. There was an 84% overall response rate. Sixty-seven per cent returned questionnaires. An additional 17% completed a telephone interview. The study group had no statistically significant increase in the rate of behavioural or psychological problems compared with the control group. There were no statistically significant differences within the study group related to sex or to multiple gestation IVF births. This large group of school-age IVF children has normal psychological development with no identified adverse effect of their status as IVF children. Determining the role, if any, of IVF in the very small number of children with behavioural and psychological problems will require additional study.

Abstract
OBJECTIVE To explore the medical issues, attitudes, concerns, and choices that parents have about their children born with the use of assisted reproductive technology (ART). DESIGN Retrospective and prospective survey. SETTING An academic medical center and a private practice. PATIENT(S) Participants who conceived and were delivered of infants in two ART programs. INTERVENTION(S) A total of 373 patients were mailed an anonymous survey, a consent form, and the Parent Child Relationship Inventory. The rate of response was approximately 49% for clinic A and 33% for clinic B. MAIN OUTCOME MEASURE(S) Pregnancy outcomes and attitudes about parenting. RESULT(S) Respondents' major concerns during pregnancy revolved around miscarriage and the infant's health; complications occurred in 38.9% of first pregnancies. Parents believed that their children were more appreciated, that their children were not emotionally different, that ART did not create ongoing medical or emotional problems, and they were not overprotective as parents. Gender differences were statistically significant on attitudinal variables. CONCLUSION(S) Parents had concerns about pregnancy. Overall, men and women felt positive about ART and their parenting. The ART experience is associated with complex choices, attitudes, and emotions.

Abstract
BACKGROUND Intracytoplasmic sperm injection (ICSI) was introduced as a new form of in-vitro fertilisation (IVF) in 1993 and is now accepted as the treatment of choice for severe male infertility in many centres around the world. However, there is little information about the long-term outcome of children conceived by ICSI. We aimed to find out the medical and developmental outcome of children conceived by ICSI at age 1 year. METHODS In this prospective study, we compared the medical and developmental outcome at 1 year of 89 children conceived by ICSI with 84 children conceived by routine IVF, and with 80 children conceived naturally. Formal developmental assessment was done with Bayley Scales of Infant Development (2nd edition) from which a mental development index (MDI) was derived. FINDINGS There was no significant difference in the incidence of major congenital malformations or major health problems in the first year of life. However, the mean Bayley MDI was significantly lower for the children conceived by ICSI than for the children conceived by routine IVF or naturally (95.9 [SD 10.7], 101.8 [8.5], and 102.5 [7.6], respectively, p < 0.0001). 15 (17%) of 89 children conceived by ICSI experienced mildly or significantly delayed development (MDI < 85) at 1 year compared with two (2%) of the 84 children conceived by IVF and one (1%) of the 80 children conceived by natural conception (p < 0.0001). INTERPRETATION Although most children conceived by ICSI are healthy and develop normally, there is an increased risk of mild delays in development at 1 year when compared with children conceived by routine IVF or conceived naturally. These findings support the need for ongoing developmental follow-up of children conceived by ICSI to see whether they are at increased risk of intellectual impairment or learning difficulties at school age.

Abstract
BACKGROUND There is uncertainty about the health of children born from in-vitro fertilisation (IVF) with cryopreserved embryos. We investigated the postnatal growth and health (up to 18 months) of these children compared with those born after standard IVF with fresh embryos and those from spontaneous pregnancies. METHODS 255 children from cryopreserved embryos were matched by maternal age, parity, single or twin pregnancy, and date of delivery with 255 children born after IVF with fresh embryos, and 252 children from spontaneous pregnancies. The main endpoint was growth; secondary endpoints were the prevalence of chronic illness, major malformations, cumulative incidence of common diseases, and development during the first 18 months. Growth was assessed by comparison with standard Swedish growth charts and by standard deviation scores. FINDINGS Growth features were similar for both singletons and twins in the three groups. There were 6 (2.4%) of 255, 9 (3.5%) of 255, and 8 (3.2%) of 252 major malformations in the cryopreserved group, standard IVF, and spontaneous groups, respectively (p=0.6 between the cryopreserved and standard IVF group). The prevalence of chronic diseases did not differ between the three groups, with 18.0%, 15.3%, and 16.7% of children with a chronic illness in the cryopreserved group, standard IVF, and spontaneous groups, respectively. INTERPRETATION The cryopreservation process does not adversely affect the growth and health of children during infancy and early childhood. Minor handicaps, behavioural disturbances, learning difficulties, and dysfunction of attention and perception cannot be ruled out at this age.

Abstract
AIMS To compare the outcome in in vitro fertilisation (IVF) children (after fresh embryo transfer) from multiple and singleton births with one another, and with normally conceived control children. METHODS A cohort of 278 children (150 singletons, 100 twins, 24 triplets and four quadruplets), conceived by IVF after three fresh embryos had been transferred, born between October 1984 and December 1991, and 278 normally conceived control children (all singletons), were followed up for four years after birth. They were assessed for neonatal conditions, minor congenital anomalies, major congenital malformations, cerebral palsy and other disabilities. Control children, all born at term, were matched for age, sex and social class. RESULTS The ratio of male:female births was 1.03. Forty six per cent of IVF children were from multiple births; 34.9% were from preterm deliveries; and 43.2% weighed less than 2500 g at birth. The IVF singletons were on average born one week earlier than the controls, weighed 400 g less, and had a threefold greater chance of being born by caesarean section. The higher percentage of preterm deliveries was largely due to multiple births and they contributed to neonatal conditions in 45.0% of all IVF children. The types of congenital abnormalities varied: 3.6% of IVF children and 2.5% of controls had minor congenital anomalies, and 2.5% of IVF children and none of the controls had major congenital malformations. The numbers of each specific type of congenital abnormality were small and were not significantly related to multiple births. IVF children (2.1%) and 0.4% of the controls had mild/moderate disabilities. They were all from multiple births, including two children with cerebral palsy who were triplets. CONCLUSIONS The outcome of IVF treatment leading to multiple births is less satisfactory than that in singletons because of neonatal conditions associated with preterm delivery and disabilities in later childhood. A reduction of multiple pregnancies by limiting the transfer of embryos to two instead of three remains a high priority.

Abstract
OBJECTIVE To contact the total cohort of children conceived by IVF-ET consecutively in our center between June 1981 and December 1988. DESIGN Retrospective study. SETTING Infertility unit of the department of Obstetrics and Gynecology, Antoine Béclère Hospital, Clamart, France. PATIENT(S) Complete information was obtained on 370 children. The percentage lost for follow-up was 9%. INTERVENTION(S) To assess the children's well-being, telephone interviews of the parents and questionnaires sent to the parents and/or pediatrician were used. MAIN OUTCOME MEASURE(S) Surgical procedures, malformation, height and weight, school performance. RESULT(S) The physical growth of these children showed no major pathological features, with only 2.2% of them being below 2 SD for weight and 0.3% for height. The rates of malformation were not significantly different between these children and the general population. School performance was good, with 92.2% presenting encouraging outcome. Fifty-eight percent of the parents of children aged 6 to 10 years old did not inform their children about the IVF nor did 34% of the parents of children aged 11 to 13. Subsequent to the birth of the IVF child, 30 patients (8.9%) had a spontaneous pregnancy. However, five of them (15.1%) were ectopic. CONCLUSION(S) This study reports, for the first time, reassuring data on the long-term assessment of a large group of older IVF-ET children conceived consecutively, with a low percentage of subjects lost for follow-up.

Abstract
Many couples seek solutions to problems of infertility by using assisted reproduction techniques. Despite very different beginnings, children conceived after donor insemination, ovum donation, in-vitro fertilisation or gamete intrafallopian transfer show no adverse long term effects, either physically or psychosocially.

Abstract
BACKGROUND Preimplantation genetic diagnosis is an exciting advance in prenatal diagnosis. However, the safety of embryo biopsy must be determined with respect to both pregnancy rate and cogenital anomalies. ANALYSIS Too few pregnancies have been reported to allow meaningful inferences to be drawn, for which reason data on pregnancy losses and anomalies after conventional IVF were first reviewed. Loss rates are approximately 25%, and anomaly rates are not increased over that observed in the general population. Unfortunately, considerable methodological problems exist in published surveys: lack of proper controls, failure to take into account potential confounding variables, anomaly surveillance that is inconsistent with respect to the vigor with which anomalies are sought, inclusion or exclusion of minor anomalies, inclusion or exclusion of anomalies evident only on ultrasound, and even inclusion or exclusion of anomalies present in terminated pregnancies. We recommend prospective surveillance for major anomalies, defined as those causing death, major handicap or requiring surgery. Prospective surveillance ideally dictates collection of intake information at the time pregnancy is diagnosed, surveillance during pregnancy to exclude teratogenic influences, and systematic neonatal anomaly surveillance.

Abstract
A cohort of 91 children from cryopreserved embryos and 83 control children who were conceived normally had their development assessed using the Griffiths's scales of mental development. The controls (81 singletons and two twins) of a similar age, sex, and social class were selected from siblings, cousins, and peers of the cryopreserved embryo group (68 singleton, 20 twins, and three triplets). Children from cryopreserved embryos had a lower mean birth weight and mean gestational age and a higher proportion were born by caesarean section. One child from the cryopreserved embryo group had Down's syndrome, three had squints, and four had conductive hearing loss while in the control children, six had squints, and nine had conductive hearing loss. In both groups, including the child with Down's syndrome, the mean Griffiths's quotient was greater than the standard 100. In the children from cryopreserved embryos, the singleton and multiple birth subgroups had statistically similar assessment results. The mean (SD) Griffiths's quotient was 105.69 (13.55) in children from cryopreserved embryos and 108.18 (9.80) in controls at a chronological age of 25.08 (12.86) and 29.19 (14.65) months respectively. Overall, the development in children from cryopreserved embryos did not cause concern though formal testing had highlighted small differences compared with other children conceived normally and of a similar social class.
