Abstract
INTRODUCTION Despite a noticeable trend of delayed fatherhood, less is known about the impact of paternal age on the paternally programmed placenta. We hypothesize that paternal aging affects seminal quality and as such induces ageing-related epigenetic alterations that influence placental growth. Our main aim is to investigate associations between paternal age and first trimester (vascular) placental growth trajectories. METHODS Pregnant women were enrolled before 10 weeks of gestation in the Rotterdam Periconceptional Cohort (Predict study). Placental volumes (PV) and utero-placental vascular volumes (uPVV) were measured at 7, 9, and 11 weeks gestation. Associations between paternal age and PV and uPVV were investigated using linear mixed models and the maximum likelihood ratio test to test non-linear relationships. We adjusted for gestational age, fetal sex, parental smoking and maternal age, BMI, education and parity, and stratified for conception mode. RESULTS From 808 pregnancies we obtained 1313 PV and from 183 pregnancies 345 uPVV measurements. We show no associations between paternal age and PV (p = 0.934) and uPVV (p = 0.489) in our total population or in pregnancies conceived naturally (PV p = 0.166; uPVV p = 0.446) and after IVF/ICSI (PV p = 0.909; uPVV p = 0.749). For example, PV was 0.9% smaller (95% CI -5.7%-7.1%) in fathers aged 40 compared to 30 years old at 9 weeks gestation in the total study population. DISCUSSION We are not demonstrating a significant impact of paternal age on first trimester placental growth in a tertiary care population. Given the trend of increasing paternal age, our study should be repeated in the general population.

Abstract
Maternal and paternal age at birth is increasing globally. Maternal age may affect perinatal outcomes, but the effect of paternal age and its joint effect with maternal age are not well established. This prospective, multicenter, cohort analysis used data from the University Hospital Advanced Age Pregnant Cohort Study in China from 2016 to 2021, to investigate the separate association of paternal age and joint association of paternal and maternal age with adverse perinatal outcomes. Of 16,114 singleton deliveries, mean paternal and maternal age (± SD) was 38.0 ± 5.3 years and 36.0 ± 4.1 years. In unadjusted analyses, older paternal age was associated with increased risks of gestational diabetes mellitus (GDM), hypertensive disorders of pregnancy, preeclampsia, placenta accreta spectrum disorders, placenta previa, cesarean delivery (CD), and postpartum hemorrhage, preterm birth (PTB), large-for-gestational-age, macrosomia, and congenital anomaly, except for small-for-gestational-age. In multivariable analyses, the associations turned to null for most outcomes, and attenuated but still significant for GDM, CD, PTB, and macrosomia. As compare to paternal age of < 30 years, the risks in older paternal age groups increased by 31-45% for GDM, 17-33% for CD, 32-36% for PTB, and 28-31% for macrosomia. The predicted probabilities of GDM, placenta previa, and CD increased rapidly with paternal age up to thresholds of 36.4-40.3 years, and then plateaued or decelerated. The risks of GDM, CD, and PTB were much greater for pregnancies with younger paternal and older maternal age, despite no statistical interaction between the associations related to paternal and maternal age. Our findings support the advocation that paternal age, besides maternal age, should be considered during preconception counseling.Trial Registration NCT03220750, Registered July 18, 2017-Retrospectively registered, https://classic.clinicaltrials.gov/ct2/show/NCT03220750 .

Abstract
PURPOSE To assess the relationships between parental ages and preterm birth subtypes. METHODS A population-based cohort analysis of California livebirths 2007-2012. Associations between maternal and paternal age with spontaneous and medically indicated preterm birth were estimated from Cox proportional hazard models. Parental age was modeled with restricted cubic splines to account for nonlinear relationships. RESULTS Young paternal age was associated with increased hazard ratios for spontaneous and medically indicated preterm birth. Older fathers showed elevated hazards for preterm birth in crude analysis but after adjustment the relationship was generally not observed. Aging mothers showed increased hazard ratios for both preterm birth phenotypes. CONCLUSIONS After adjusting for parental demographics, births to younger fathers and older mothers had the highest risks for spontaneous preterm birth. The paternal influence on preterm birth was observed to be independent of maternal factors.

Abstract
INTRODUCTION To study whether paternal age exerts an effect, independent of maternal age, on the outcomes of fresh in vitro fertilization/ intracytoplasmic sperm injection (IVF/ICSI) cycles. Semen quality deteriorates with increasing paternal age; however, there is conflicting evidence for any impact paternal age may have on the outcome of IVF/ICSI. Several retrospective and prospective cohort studies have shown that paternal age increases the miscarriage rate and reduces the live birth rate. Some studies have shown no effect of paternal age on live birth rate or miscarriage rate. Studies involving donor oocytes have tended to show no independent effect of paternal age on assisted reproductive technology (ART) outcomes. The age at which paternal age may exert a significant deleterious effect on outcome is not known and there is no limit to paternal age in IVF/ICSI treatment. MATERIAL AND METHODS A single-center retrospective cohort study was carried out at the Centre for Reproductive and Genetic Health, London, UK. Included in the analysis were all couples with primary or secondary infertility undergoing IVF/ICSI cycles in which the male partner produced a fresh semen sample and the cycle proceeded to fresh embryo transfer. All cycles of IVF/ICSI that used donor oocytes-donor sperm, frozen sperm, cycles leading to embryo storage and cycles including preimplantation genetic testing (PGT-A/PGT-M)-were excluded from analysis. The primary outcome was live birth rate and secondary outcomes were clinical pregnancy rate and miscarriage rate. Multivariate logistic regression analysis with live birth as a dependent variable and maternal and paternal age class as independent variables was performed. RESULTS During the study period there were 4833 cycles, involving 4271 men, eligible for analysis; 1974/4833 (40.8%, 95% confiene intervals [CI] 39.5-42.2%) cycles resulted in a live birth. A significantly lower proportion of men over 51 years met World Health Organization semen analysis criteria (56/133, [42.1%, 95% CI 34.1-50.6]) compared with men under 51 years of age (2530/4138 [61.1%, 95% CI 60.0-62.6]) (p = 0.001). Both maternal and paternal age were retained in the multivariate model and for all maternal age subgroups the probability of live birth decreased with paternal age over 50 years (odds ratio [OR] 0.674, 95% CI 0.482-0.943) (p = 0.021). Paternal age over 50 years was not an independent predictor of miscarriage (OR 0.678, 95% CI 0.369-1.250) (p = 0.214). CONCLUSIONS Paternal age over 50 significantly affects the chance of achieving a live birth following ART. Paternal age does not independently affect the risk of miscarriage following ART. There should be a public health message for men not to delay fatherhood.

Abstract
BACKGROUND Maternal morbidity continues to be an issue of national and global concern. Paternal preconception health may play a significant role in pregnancy outcomes and has received less attention than maternal health. OBJECTIVE This study aimed to examine the association between preconception paternal health and the risk for adverse maternal outcomes among healthy mothers. STUDY DESIGN This was a retrospective analysis of live births from 2009 through 2016 to healthy women aged 20 to 45 years recorded in the IBM Marketscan research database. Infants were linked to paired mothers and fathers using family ID. Preconception paternal health was assessed using the number of metabolic syndrome component diagnoses and the most common individual chronic disease diagnoses (hypertension, diabetes mellitus, obesity, hyperlipidemia, chronic obstructive pulmonary disease, cancer, and depression). Women with metabolic syndrome components were excluded to avoid potential confounding of maternal and paternal factors. Adverse maternal outcomes that were assessed included (1) abnormal placentation including placenta accreta spectrum, placenta previa, and placental abruption; (2) preeclampsia with and without severe features including eclampsia; and (3) severe maternal morbidity, identified as any indicator from the Centers for Disease Control and Prevention Index of life-threatening complications at the time of delivery to 6 weeks postpartum. The trend between preconception paternal health and each maternal outcome was determined using the Cochran-Armitage Trend test. The independent association of paternal health with maternal outcomes was also determined using generalized estimating equations models, accounting for some mothers who contributed multiple births during the study period, and by adjusting for maternal age, paternal age, region of birth, year of birth, maternal smoking, and average number of outpatient visits per year. RESULTS Among 669,256 births to healthy mothers, there was a significant trend between all adverse maternal outcomes and worsening preconception paternal health defined either as the number of metabolic syndrome diagnoses or number of chronic disease diagnoses (P<.001; Cochran-Armitage Trend test). In the generalized estimating equations model, the odds for preeclampsia without severe features increased in a dose-dependent fashion and were 21% higher (95% confidence interval, 1.17-1.26) among women whose partners had ≥2 metabolic syndrome diagnoses than among women whose partners had no metabolic syndrome diagnosis. The odds for preeclampsia with severe features and eclampsia increased in a dose-dependent fashion and were 19% higher (95% confidence interval, 1.09-1.30) among women whose partners had ≥2 metabolic syndrome diagnoses than among women whose partners had no metabolic syndrome diagnosis. The odds for severe maternal morbidity were 9% higher (95% confidence interval, 1.002-1.19) among women whose partners had ≥2 metabolic syndrome diagnoses than among women whose partners had no metabolic syndrome diagnosis. The odds for abnormal placentation were similar between the groups (adjusted odds ratio, 0.96; 95% confidence interval, 0.89-1.03). CONCLUSION Among healthy mothers, we report that preconception paternal health is significantly associated with increased odds of preeclampsia with and without severe features and weakly associated with increased odds of severe maternal morbidity. These findings suggest that paternally derived factors may play significant roles in the development of adverse maternal outcomes in healthy women with a low a priori risk of obstetrical complications.

Abstract
Background Worldwide several studies have examined the associations of fetal sex, paternal age and maternal age with pregnancy outcomes, with the evidence regarding paternal age being less consistent. Although in Taiwan we keep good records on birth certificates, these issues have been seldom researched. Our objective was to assess the association of fetal sex and parental age with gestational hypertension/preeclampsia, eclampsia and preterm delivery in the Taiwanese population. Methods We conducted a nationwide study and included 1,347,672 live births born between 2004 and 2011 in Taiwan. Gestational hypertension/preeclampsia and eclampsia were ascertained based on the International Classification of Diseases codes; preterm delivery (< 37 weeks) was defined according to the gestational age documented by healthcare providers. We implemented logistic regression models with covariates adjusted to assess the association of fetal sex and parental age with pregnancy outcomes. Results The prevalence was 2.27% for gestational hypertension/preeclampsia, 0.07% for eclampsia and 6.88% for preterm delivery. After considering other parent’s age and covariates, we observed a significantly stepped increase in the risk of both gestational hypertension/preeclampsia and preterm delivery as paternal and maternal age increased. For example, fathers aged ≥50 years were associated with a significantly higher risk of gestational hypertension/preeclampsia (odds ratio [OR]: 1.60, 95% CI: 1.39, 1.84) and preterm delivery (OR: 1.38, 95% CI: 1.27, 1.51) than fathers aged 25–29 years. Analysis on fetal sex showed that relatively more female births were linked to gestational hypertension/preeclampsia and more male births linked to preterm delivery, compared to the whole population. Conclusions We found both paternal and maternal age, as well as fetal sex, were associated with the risk of pregnancy outcomes. Some findings on fetal sex contradicted with previous research using non-Asian samples, suggesting that ethnicity may play a role in the association of fetal sex and pregnancy outcomes. Besides, there is a need to counsel couples who are planning their family to be aware of the influence of both advanced maternal and paternal age on their pregnancy outcomes.

Abstract
The role of fathers prior to conception, during pregnancy, and in the post-partum period has generally not been a key consideration for Obstetric Physicians. However, this view may need challenging. This paper outlines the key importance of fathers in all phases of obstetric medical care. We review the contribution of paternal factors such as genetics, health, and lifestyle to fetal development, pregnancy complications, and maternal and neonatal wellbeing. The role of fathers in complex care decisions during pregnancy is also reviewed. Postpartum, fathers have a substantial role in shaping the future of the family unit through encouraging breastfeeding and creating a supportive environment for motherhood. This review proposes areas for future research and recommends an evidence-based change in practice in obstetric medicine that focuses on recognizing the role of fathers in the pregnancy journey.

Abstract
OBJECTIVE To evaluate the impact of advanced paternal age on maternal and perinatal outcomes in the United States. DESIGN Retrospective, population based cohort study. SETTING US. POPULATION 40 529 905 documented live births between 2007 and 2016. MAIN OUTCOME MEASURES Primary perinatal outcomes were gestational age, birth weight, Apgar score at five minutes, admission to a neonatal intensive care unit, need for postpartum antibiotics, and seizures. Primary maternal outcomes were gestational diabetes and pre-eclampsia. Secondary outcome was the number of preventable perinatal events. RESULTS Higher paternal age was associated with an increased risk of premature birth, low birth weight, and low Apgar score. After adjustment for maternal age, infants born to fathers aged 45 years or older had 14% higher odds of premature birth (odds ratio 1.14, 95% confidence interval 1.13 to 1.15), independent of gestational age, and 18% higher odds of seizures (1.18, 0.97 to 1.44) compared with infants of fathers aged 25 to 34 years. The odds of gestational diabetes was 34% higher (1.34, 1.29 to 1.38) in mothers with the oldest partners. 13.2% (95% confidence interval 12.5% to 13.9%) of premature births and 18.2% (17.5% to 18.9%) of gestational diabetes in births associated with older fathers were estimated to be attributable to advanced paternal age. CONCLUSIONS Advanced paternal age is associated with negative effects on both mothers and offspring. Given the relatively low prevalence of advanced paternal age in the US, population level impacts are currently modest. Nevertheless, as advanced paternal age has doubled in the US over the past generation, further investigation is warranted of the impact on birth outcomes and public health.

RESULTS Advanced paternal age (> 40 years) is associated with accumulated damage to sperm DNA and mitotic and meiotic quality control mechanisms (mismatch repair) during spermatogenesis. This in turn causes well-delineated abnormalities in sperm chromosomes, both numerical and structural, and increased sperm DNA fragmentation (3%/year of age) and single gene mutations (relative risk, RR 10). An increase in related abnormalities in offspring has also been described, including miscarriage (RR 2) and fetal loss (RR 2). There is also a significant increase in rare, single gene disorders (RR 1.3 to 12) and congenital anomalies (RR 1.2) in offspring. Current research also suggests that autism, schizophrenia, and other forms of "psychiatric morbidity" are more likely in offspring (RR 1.5 to 5.7) with advanced paternal age. Genetic defects related to faulty sperm quality control leading to single gene mutations and epigenetic alterations in several genetic pathways have been implicated as root causes. CONCLUSIONS Advanced paternal age is associated with increased genetic and epigenetic risk to offspring. However, the precise age at which risk develops and the magnitude of the risk are poorly understood or may have gradual effects. Currently, there are no clinical screenings or diagnostic panels that target disorders associated with advanced paternal age. Concerned couples and care providers should pursue or recommend genetic counseling and prenatal testing regarding specific disorders.

Abstract
Male pattern hair loss (MPHL) is exceedingly common. It is characterised by onset in early adulthood and progression with age. It has a strong heritable component. The reason for its existence remains unexplained. Given that MPHL is progressive and has its earliest manifestations in young adults it may be a barometer of age. Here we suggest that MPHL may have atavistically allowed women in our species and ancestor species to select younger (but not necessarily the youngest) adult mates. Evidence suggests that conceptions by younger fathers are more likely to lead to live births and less likely to result in miscarriage. Further children fathered by younger men may have improved health and be less likely to suffer from a number of co-morbidities. This is collectively known as the "paternal age affect". Hence the selection of younger males mediated by the MPHL may improve the fitness of the population and of the species at the expense of the individual. Indeed MPHL may have been an evolutionary "nudge" directing women to favour younger partners. It is conceivable that for a species whose success is predicated upon co-operation, collaboration and altruism the gene cannot be exclusively selfish and must have a selfless allele.

Abstract
IMPORTANCE In recent decades, a trend toward delayed childbearing is noted in developed countries. Whereas the effects of maternal age on fertility, pregnancy complications, and postnatal outcomes have been thoroughly explored, consequences of advanced paternal age are less well known. Oocyte donation cycles can be used as an optimal model to analyze the association between male ageing and reproductive outcomes with minimal confounding. OBJECTIVE The purpose of this work was to summarize the updated and relevant literature dealing with the effect of paternal age on oocyte donation outcomes. RESULTS According to the available evidence from oocyte donation cycles, it seems that no significant association exists between advanced paternal age and fertility. However, this evidence is based on few studies, many of which are of low quality, yielding conflicting results. In addition, the emerging evidence clearly indicates an increased risk of adverse postnatal manifestations of pregnancies conceived by older fathers, including de novo autosomal dominant disorders, impaired neurocognitive development, and increased risk of malignancy. CONCLUSIONS AND RELEVANCE This review may be of aid to medical practitioners in counseling couples on the risks of delayed childbearing.

Abstract
Pre-eclampsia is a risk factor for later life vascular and metabolic diseases. This study postulates that this reflects a common genetic cause, and investigates whether the INSR rs2059806 single nucleotide polymorphism (SNP) (a risk factor for essential hypertension, type 2 diabetes and metabolic syndrome) is also associated with pre-eclampsia. The association of INSR rs2059806 with pre-eclampsia was tested in two cohorts - a Caucasian case control group (123 pre-eclamptic mother-father-baby trios and 1185 mother-father-baby trios from uncomplicated pregnancies) and an independent cohort of Sinhalese women (175 women with pre-eclampsia and 171 women with uncomplicated pregnancies). In the Caucasian cohort, the prevalence of the INSR rs2059806 AA genotype was greater among pre-eclamptic women compared with the uncomplicated pregnancies (12.7% versus 4.7%, OR[95%CI] = 3.1[1.6-5.8], P = 0.0003). In the Sinhalese cohort, maternal INSR rs2059806 AA genotype was greater among pre-eclamptic women who delivered small for gestational age infants compared with the uncomplicated pregnancies (10.8% versus 4.2%, OR[95%CI] = 2.8[1.0-7.4], P = 0.03). Thus, it was found that the INSR rs2059806 SNP is also associated with pre-eclampsia phenotypes in two independent cohorts suggesting that genetic susceptibility may be implicated in the link between pre-eclampsia and subsequent vascular and metabolic diseases.

Abstract
In this article we review the epidemiologic evidence for adverse health effects in offspring of fathers of advanced age. First the evidence regarding fetal survival is addressed, and afterward we review the evidence regarding morbidity in children with older fathers. The adverse conditions most consistently associated with increased paternal age are stillbirths, musculo-skeletal syndromes, cleft palate, acute lymphoblastic leukemia and retinoblastoma, and neurodevelopmental disorders in the autism spectrum and schizophrenia. Finally, we consider the public health impact of the increasing paternal age. We conclude that the adverse health effects in children that might be caused by the present increase in paternal age are severe but quantitatively of minor importance. However, identification of morbidities that are more frequent in offspring of older fathers, after having taken any maternal age effects and other confounding into account, may lead to a better understanding of the pathogenesis behind such conditions.

Abstract
The increased paternal age at conception (PAC) has been associated with autism spectrum disorder (ASD), schizophrenia and other neurodevelopmental disorders, thus raising questions that imply, potential health concerns in the offspring. As opposed to female oogonia, the male germ cells undergo hundreds of cell divisions during the fertile years. Thus, the advanced paternal age is associated with increase of point mutations in the male spermatogonia DNA, implying that this could be the major driving mechanism behind the paternal age effect observed in the offspring. In addition to replication errors, DNA replication fidelity and inefficient DNA repair machinery in the spermatogonia also contribute to the mutagenic load. Our study population consisted of 38 nonagenarians, participants in the Vitality 90+ Study, born in the year 1920 (women n = 25, men n = 13), for whom the parental birth dates were available. The gene expression profile of the study subjects was determined with HumanHT-12 v4 Expression BeadChip from peripheral blood mononuclear cells. We used Spearman's rank correlation to look for the associations of gene expression with paternal age at conception. Associated transcripts were further analyzed with GOrilla and IPA to determine enriched cellular processes and pathways. PAC was associated with the expression levels of 648 transcripts in nonagenarian subjects. These transcripts belonged to the process of mitochondrial translational termination and the canonical pathway of Mitochondrial dysfunction, more specifically of Oxidative phosphorylation. The observed systematic down-regulation of several mitochondrial respiratory chain components implies compromised function in oxidative phosphorylation and thus in the production of chemical energy.

Abstract
Preeclampsia (PE) is one of the leading causes of maternal and fetal morbidity and mortality, with incidence rates ranging between 2 and 5 % in the Western World. The exact causes of the disease remain largely unknown, because of the complex pathophysiologic mechanisms involved in the process. Genetic, environmental, and epigenetic parameters have been implicated by various authors as culprits for the pathogenesis of PE. Recent reports in the literature highlight the paternal role. Still, the exact extent and mechanism remain elusive. In this systematic review, we attempt to present data regarding the paternal role in a concise and comprehensive manner.

Abstract
It has been well established that a previous pregnancy exhibits a beneficial effect on the subsequent pregnancy. However, the underlying mechanisms have not been defined. We hypothesized that multiparity may affect decidualization process during early pregnancy. To test this hypothesis, we analyzed global gene changes associated with multiparity in the mouse uterus using RNA-sequencing (RNA-seq). We identified a total of 131 differentially expressed genes (fold change > 2 and false discovery rate < 0.05), of which 58 were downregulated and 73 genes were upregulated in the second pregnancy (SP) compared to the first pregnancy. Functional clustering analysis showed that genes involved in stress response were significantly enriched. Most importantly, a significant portion of differentially expressed genes, 14 genes or 10.7%, overlapped with the gene list associated with decidualization. Quantitative reverse transcription (RT) polymerase chain reaction (qRT-PCR) analysis confirmed a decreased expression of 4 genes (Klk1, kallikrein 1; H2-Eb1, histocompatibility 2 class II antigen E beta; Mmp7, matrix metallopeptidase 7; Pdpn, podoplanin) and an increase in expression of 2 genes (Thy1, thymus cell antigen 1; Ptgs2, prostaglandin-endoperoxide synthase 2) in SP. Beyond protein-coding genes, we also identified a differentially expressed long noncoding RNA AI506816. Our data provide new insights into the molecular mechanisms underlying the beneficial effect of multiparity.

Abstract
Over the last decade, there has been a significant increase in average paternal age when the first child is conceived, either due to increased life expectancy, widespread use of contraception, late marriages and other factors. While the effect of maternal ageing on fertilization and reproduction is well known and several studies have shown that women over 35 years have a higher risk of infertility, pregnancy complications, spontaneous abortion, congenital anomalies, and perinatal complications. The effect of paternal age on semen quality and reproductive function is controversial for several reasons. First, there is no universal definition for advanced paternal ageing. Secondly, the literature is full of studies with conflicting results, especially for the most common parameters tested. Advancing paternal age also has been associated with increased risk of genetic disease. Our exhaustive literature review has demonstrated negative effects on sperm quality and testicular functions with increasing paternal age. Epigenetics changes, DNA mutations along with chromosomal aneuploidies have been associated with increasing paternal age. In addition to increased risk of male infertility, paternal age has also been demonstrated to impact reproductive and fertility outcomes including a decrease in IVF/ICSI success rate and increasing rate of preterm birth. Increasing paternal age has shown to increase the incidence of different types of disorders like autism, schizophrenia, bipolar disorders, and childhood leukemia in the progeny. It is thereby essential to educate the infertile couples on the disturbing links between increased paternal age and rising disorders in their offspring, to better counsel them during their reproductive years.

Abstract
Reduced fertility typically occurs among women in their late 30s, but increasing evidence indicates that advanced paternal age is associated with changes in reproduction as well. Numerous studies have investigated age-based declines in semen traits, but the impact of paternal age on semen parameter values remains inconclusive. Using data from 90 studies (93,839 subjects), we conducted a systematic review and meta-analysis to quantify the effect of male age on seven ejaculate traits (semen volume, sperm concentration, total sperm count, morphology, total motility, progressive motility and DNA fragmentation). Age-associated declines in semen volume, percentage motility, progressive motility, normal morphology and unfragmented cells were statistically significant and results generally seemed to be robust against confounding factors. Unexpectedly, sperm concentration did not decline with increasing male age, even though we found that sperm concentration declined over time. Our findings indicate that male age needs more recognition as a potential contributor to the negative pregnancy outcomes and reduced offspring health associated with delayed first reproduction. We suggest that greater focus on collection of DNA fragmentation and progressive motility in a clinical setting may lead to better patient outcomes during fertility treatments of aging couples.

Abstract
Birth data from developed countries indicates that the average paternal age is increasing. As the trend to older fatherhood has become established, concerns have been raised that this may be linked to adverse outcomes, such as pregnancy complications, congenital anomalies, and long-term health implications for the child. Since the sperm of older fathers may be impaired due to the general effects of ageing, their offspring may be at risk due to defects in sperm quality at conception. A literature search was performed to identify pregnancy complications, fetal anomalies and health issues for the child when the father is in an older age bracket. Evidence for impairment in the sperm and genetic material of older fathers was reviewed. With an older father, there is evidence of an increase in stillbirths and a slightly increased risk of autism, bipolar disorder and schizophrenia in the offspring later in life. The increased risk of achondroplasia has long been recognised. For the mother, there is an increased rate of Caesarean section. Investigations of other possible adverse outcomes have produced mixed findings. Further robust and longitudinal studies are needed to clarify these issues.

Abstract
BACKGROUND Advanced paternal age at birth has been linked to several psychiatric disorders in offspring (e.g. schizophrenia) and genetic mechanisms are thought to underlie these associations. This study is the first to investigate whether advanced paternal age at birth is associated with eating disorder risk using a twin study design capable of examining both phenotypic and genetic associations. METHOD In a large, population-based sample of female twins aged 8-17 years in mid-puberty or beyond (n = 1722), we investigated whether advanced paternal age was positively associated with disordered eating symptoms and an eating disorder history [i.e. anorexia nervosa (AN), bulimia nervosa (BN) or binge eating disorder (BED)] in offspring. Biometric twin models examined whether genetic and/or environmental factors underlie paternal age effects for disordered eating symptoms. RESULTS Advanced paternal age was positively associated with disordered eating symptoms and an eating disorder history, where the highest level of pathology was observed in offspring born to fathers ⩾40 years old. The results were not accounted for by maternal age at birth, body mass index (BMI), socio-economic status (SES), fertility treatment or parental psychiatric history. Twin models indicated decreased genetic, and increased environmental, effects on disordered eating with advanced paternal age. CONCLUSIONS Advanced paternal age increased risk for the full spectrum of eating pathology, independent of several important covariates. However, contrary to leading hypotheses, environmental rather than genetic factors accounted for paternal age-disordered eating associations. These data highlight the need to explore novel (potentially environmental) mechanisms underlying the effects of advanced paternal age on offspring eating disorder risk.

Abstract
Infant mortality is the most widely used indicator of a nation's health status and is associated with a plethora of maternal and socioeconomic factors. Although the association between young and old maternal age and the risk of infant mortality is well established, the link between paternal age and birth outcomes has received far less attention. This study seeks to examine the added impact of paternal age on infant mortality, above and beyond that of maternal age among married couples. Using the 2002 linked birth and infant death data set (N = 63,754), hazard odds ratios for the association between combined adolescent and adult maternal and paternal age and the risk of infant mortality were estimated. Maternal demographic characteristics, such as education and race/ethnicity were controlled. The findings indicate that, independent of maternal education and race/ethnicity, adolescent father adds additional risk, above and beyond that of maternal age, only when the mother is older (21-45 years; hazard ratio = 2.7). This study highlights that for married couples, adolescent fathers add to the risk of infant mortality when the mothers are older, providing insight into the role of paternal age in infant mortality. Implications for additional research are discussed.

Abstract
STUDY QUESTION Is the age of the father associated with placental weight or the ratio of placental weight to birthweight? SUMMARY ANSWER Placental weight and placental to birthweight ratio increased according to increasing paternal age, also after adjustment for maternal age. WHAT IS KNOWN ALREADY High paternal age and also high placental to birthweight ratio have been associated with adverse pregnancy outcome. STUDY DESIGN, SIZE AND DURATION We performed a population-based study and included all singleton births after 22 weeks of gestation in the Medical Birth Registry of Norway (n = 590,835) during the years 1999-2009. PARTICIPANTS/MATERIALS, SETTING, METHODS We compared mean placental weight and placental to birthweight ratio between paternal age groups. The association of paternal age with placental weight was estimated by linear regression analyses, and adjustments were made for maternal age, birthweight, parity, offspring sex, gestational age at birth, maternal smoking, pre-eclampsia, maternal diabetes mellitus and pregnancy after assisted reproductive technology (ART). MAIN RESULTS AND THE ROLE OF CHANCE In pregnancies with fathers aged 20-24 years old, the mean placental weight was 656.2 g [standard deviation (SD) 142.8], whereas it was 677.8 g (SD 160.0) in pregnancies with fathers aged 50 years or older (P < 0.001). The mean offspring birthweight in pregnancies with fathers aged 20-24 year old was 3465.0 g (SD 583.8), and it was 3498.9 g (SD 621.8) when the father was 50 years or older (P < 0.001). The placental to birthweight ratio in the corresponding paternal age groups were 0.191 (SD 0.039) and 0.196 (SD 0.044) (P < 0.001). In multivariable linear regression analysis the placentas in pregnancies fathered by a man of 50 years or older were estimated to weigh 13.99 g [95% confidence interval (CI) 10.88-17.10] more than in pregnancies with a 20-24-year-old father (P < 0.001) after adjustment for maternal age, birthweight, parity, offspring sex, gestational age at birth, maternal smoking, pre-eclampsia, maternal diabetes mellitus and pregnancy after ART. LIMITATIONS, REASONS FOR CAUTION Paternal age explains only a small proportion of the total variation in placental weight. WIDER IMPLICATIONS OF THE FINDINGS Our findings may increase the understanding of the father's role in human pregnancy.

Abstract
BACKGROUND To investigate the obstetrical and perinatal impact of oocyte donation, a cohort of women who conceived after OD was compared with a matched control group of women who became pregnant through in vitro fertilisation with autologous oocytes (AO). METHODS A matched-pair analysis has been performed at the Centre for Reproductive Medicine of the UZ Brussel, Dutch speaking Free University of Brussel. A total of 410 pregnancies resulted in birth beyond 20 weeks of gestation occurring over a period of 10 years, including 205 oocyte donation pregnancies and 205 ICSI pregnancies with autologous oocytes (AO). Patients in the OD group were matched on a one-to-one basis with the AO group in terms of age, ethnicity, parity and plurality. Matched groups were compared using paired t-tests for continuous variables and McNemar test for categorical variables. A conditional logistic regression analyses was performed adjusting for paternal age, age of the oocyte donor, number of embryos transferred, and singleton/twin pregnancy. RESULTS Oocyte donation was associated with an increased risk of pregnancy induced hypertension (PIH) (matched OR: 1.502 CI: 1.024-2.204), and first trimester bleeding (matched OR: 1.493 CI: 1.036-2.15). No differences were observed between the two matched groups with regard to gestational age, mean birth weight and length, head circumference and Apgar scores. CONCLUSIONS Oocyte donation is associated with an increased risk for PIH and first trimester bleeding independent of the recipients' age, parity and plurality, and independent of the age of the donor or the partner. However, oocyte donation has no impact on the overall perinatal outcome.

Abstract
Research investigating the role of paternal age in adverse birth outcomes is limited. This population-based retrospective cohort study used the Missouri maternally linked data set from 1989 to 2005 to assess whether paternal age affects fetal birth outcomes: low birth weight (LBW), preterm birth (PTB), stillbirth, and small size for gestational age (SGA). We examined these outcomes among infants across seven paternal age-groups (<20, 20-24, 25-29, 30-34, 35-39, 40-45, and >45 years) using the generalized estimating equation framework. Compared with infants born to younger fathers (25-29 years), infants born to fathers aged 40 to 45 years had a 24% increased risk of stillbirth but a reduced risk of SGA. A 48% increased risk of late stillbirth was observed in infants born to advanced paternal age (>45 years). Moreover, advanced paternal age (>45 years) was observed to result in a 19%, 13%, and 29% greater risk for LBW, PTB, and VPTB (very preterm birth) infants, respectively. Infants born to fathers aged 30 to 39 years had a lower risk of LBW, PTB, and SGA, whereas those born to fathers aged 24 years or younger had an elevated likelihood of experiencing these same adverse outcomes. These findings demonstrate that paternal age influences birth outcomes and warrants further investigation.

Abstract
INTRODUCTION Pregnancies complicated by preeclampsia and small-for-gestational-age (SGA) infants share placental vascular abnormalities and both disorders confer increased risk of later life coronary artery disease. Kinase insert domain receptor (KDR) is the main receptor for vascular endothelial growth factor A, a potent angiogenic factor which regulates the development of the placental vasculature. Two polymorphisms in KDR (-604T/C and Val297Ile) are known to be associated with coronary artery disease. We investigated the association of these polymorphisms with preeclampsia, gestational hypertension, and SGA infants. METHOD Nulliparous pregnant women, their partners, and infants were recruited to a prospective cohort study (n = 1169). Doppler ultrasound of the uterine and umbilical arteries was performed at 20 weeks of gestation. Preeclampsia, gestational hypertension, and SGA were defined according to international guidelines. DNA extracted from peripheral venous or cord blood was genotyped using the Sequenom MassARRAY system. Multivariable logistic regression was used to compare the odds for the pregnancy complications between the genotype groups adjusting for potential confounders. RESULTS Among 937 Caucasian pregnancies, 427 (45.6%) were uncomplicated, 75 (8.0%) developed preeclampsia, 102 (10.9%) developed gestational hypertension, and 72 (7.7%) had SGA infants in the absence of maternal hypertensive disease. Paternal and neonatal KDR-604T/C was associated with preeclampsia (adjusted odds ratio [aOR] 1.6, 95% confidence interval [CI] 1.0-3.0 and aOR 2.2, 95% CI 1.0-4.4), SGA (aOR 1.9, 95% CI 1.1-3.3 and aOR 2.2, 95% CI 1.2-3.9), and SGA with abnormal Doppler (aOR 2.7, 95% CI 1.2-5.9 and aOR 3.2, 95% CI 1.2-5.9). CONCLUSION Paternal and neonatal carriage of the KDR-604T/C polymorphism is associated with the risk of preeclampsia and SGA infants.

Abstract
The aim of the presented study is to determine the effect of different sperm parameters on the pregnancy rate of intrauterine insemination (IUI) cycles in women with favourable fertility characteristics treated for infertility. Medical records of 212 infertile couples who had undergone a total of 253 cycles were reviewed retrospectively. Inclusion criteria for women were age <35 years, antral follicle count >5, FSH <15 IU/ml, and at least one patent tube documented by HSG or laparoscopy. Clinical pregnancy rates were achieved as 15.8% per cycle, and 18.8% per couple. Woman's age, partner's age, total number of motile sperm (TMS) and motility, significantly influenced pregnancy rate. Pregnancy rate was the highest when women were aged <25 and TMS >10 × 10(6). Partner's age significantly affected the pregnancy rate per cycle in women aged <30 years and TMS >10 × 10(6). Woman's age (OR: 5.4 95% CI: 1.2-24.3) and TMS (OR: 0.06 95% CI: 0.003-0.89) were predictor variables as regards to pregnancy. Pregnancy rate was the highest in IUI cycles when woman was <25 years old, TMS was >10 × 10(6), and morphology was >4%. Male age was found to be another determining factor for IUI success, even if they had a normal spermiogram.

Abstract
Preeclampsia is often considered as simply a maternal disease with variable degrees of fetal involvement. More and more the unique immunogenetic maternal-paternal relationship is appreciated, and also the specific 'genetic conflict' that is characteristic of haemochorial placentation. From that perspective, pre-eclampsia can be seen as a disease of an individual couple with primarily maternal and fetal manifestations. The maternal and fetal genomes perform different roles during development. Heritable paternal, rather than maternal, imprinting of the genome is necessary for normal trophoblast development. Large population studies have estimated that 35% of the variance in susceptibility to preeclampsia is attributable to maternal genetic effects; 20% to fetal genetic effects (with similar contributions of both parents), 13% to the couple effect, less than 1% to the shared sibling environment and 32% to unmeasured factors. Not one of these large population studies focussed on the paternal contribution to preeclampsia, which is demonstrated by (1) the effect of the length of the sexual relationship; (2) the concept of primipaternity versus primigravidity; and (3) the existence of the so-called 'dangerous' father, as demonstrated in various large population studies. It is currently unknown how the father exerts this effect. Possible mechanisms include seminal cytokine levels and their effect on maternal immune deviation, specific paternal HLA characteristics and specific paternal single nucleotide polymorphisms (SNPs), in particular in the paternally expressed genes affecting placentation. Several large cohort studies, including the large international SCOPE consortium, have identified paternal SNPs with strong associations with preeclampsia.

Abstract
OBJECTIVE Our study investigates a possible couple predisposition for pregnancy-related hypertensive disorders (PRHDs). MATERIALS AND METHODS We selected 350 women with PRHDs and a random control cohort without PRHDs. We analyzed their clinical files and asked them and their partners about clinical information and family history for some common pathologies. Statistical bivariate and multivariate analysis was performed by R, considering significant p<0.05. RESULTS Familial history reveals in cases more maternal grandparents hypertension and thrombophilia, and paternal, personal and familial, thrombophilia history than in controls. By multivariate analysis, the occurrence of PRHDs is influenced by stress, maternal BMI, maternal chronic hypertension, pre-pregnancy diabetes mellitus, nulliparity, maternal grandmother and grandfather hypertension; and academic degrees is a protective factor. Selecting only multipara, PRHDs correlate with advanced maternal age, higher maternal BMI, chronic hypertension, longer interpregnancy interval, stress, previous pregnancies affected by PRHDs, and paternal, personal and familial, thrombophilia history. Moreover the multivariate logistic regression models considering parents familial and personal history results are accurate to predict PRHDs with an AUC of 79% in the general population and 82% among multiparous women. CONCLUSIONS The couple should be evaluated together for PRHDs risk, both parents familial history should be considered in PRHDs screening programs, and further studies are required, in a society continuously changing its characteristics and habits.

Abstract
OBJECTIVE Paternal characteristics have never been considered in the relation between maternal schizophrenia and adverse pregnancy outcomes. The aim of our study was to consider different paternal ages while investigating the relation between maternal schizophrenia and low birth weight (LBW), using a nationwide population-based dataset. METHOD Our study used data from the 2001 to 2003 Taiwan National Health Insurance Research Dataset and birth certificate registry. A total of 543 394 singleton live births were included. We performed multivariate logistic regression analyses to explore the relation between maternal schizophrenia and the risk of LBW, taking different paternal age groups into account (aged 29 years or younger, 30 to 39 years, and 40 years and older), and after adjusting for other characteristics of infant, mother, and father as well as the difference between the parent's ages. RESULTS Mothers with schizophrenia had a higher percentage of LBW infants than mothers who did not (11.8%, compared with 6.8%). For infants whose mothers had schizophrenia, the adjusted odds ratios of LBW were 1.47 (95% CI 1.02 to 2.27, P < 0.05) and 2.80 (95% CI 1.42 to 5.51, P < 0.01) times greater than for infants whose mothers did not have schizophrenia, for paternal age groups of 30 to 39 years and 40 years or older, respectively. However, maternal schizophrenia was not a significant predictor of LBW for infants whose fathers were aged 29 years and younger. CONCLUSIONS The relation between LBW and maternal schizophrenia is modified by paternal age. More attention should be paid to the interaction of paternal characteristics and maternal psychiatric disorders in producing adverse pregnancy outcomes.

Abstract
Schizophrenia has been linked to advanced paternal age, but the explanation is unknown. We questioned whether the incidence of schizophrenia would be related to male reproductive capacity, as reflected in the time taken to conceive. We measured the incidence of schizophrenia in relation to time to conception in a sub-group of 12,269 in the Jerusalem cohort whose mothers, interviewed post-partum, reported that the pregnancy had been intended. Compared with those conceived in less than 3 months, the unadjusted relative risks (RR) of schizophrenia associated with conception-waits of 3-5, 6-11 and 12+ months were 1.10 (95% confidence interval, 0.62-1.94), 1.41 (0.79-2.52) and 1.88 (1.05-3.37) with p for trend=0.035. This trend was attenuated somewhat by adjusting for paternal age, and was observed more strongly in offspring of fathers aged 30+ (p=.010). These findings suggest that factors associated with fecundability, either male or female, may contribute to the risk of schizophrenia.

Abstract
BACKGROUND A consistent association between paternal age and their offspring's risk of schizophrenia has been observed, with no independent association with maternal age. The relationship of paternal and maternal ages with risk of bipolar affective disorders (BPAD) in the offspring is less clear. The present study aimed at testing the hypothesis that paternal age is associated with their offspring's risk of BPAD, whereas maternal age is not. METHOD This population-based cohort study was conducted with individuals born in Sweden during 1973-1980 and still resident there at age 16 years. Outcome was first hospital admission with a diagnosis of BPAD. Hazard ratios (HRs) were calculated using Cox's proportional hazard regression. RESULTS After adjustment for all potential confounding variables except maternal age, the HR for risk of BPAD for each 10-year increase in paternal age was 1.28 [95% confidence interval (CI) 1.11-1.48], but this fell to 1.20 (95% CI 0.97-1.48) after adjusting for maternal age. A similar result was found for maternal age and risk of BPAD [HR 1.30 (95% CI 1.08-1.56) before adjustment for paternal age, HR 1.12 (95% CI 0.86-1.45) after adjustment]. The HR associated with having either parent aged 30 years or over was 1.26 (95% CI 1.01-1.57) and it was 1.45 (95% CI 1.16-1.81) if both parents were >30 years. CONCLUSIONS Unlike schizophrenia, the risk of BPAD seems to be associated with both paternal and maternal ages.

Abstract
Reports on autism and parental age have yielded conflicting results on whether mothers, fathers, or both, contribute to increased risk. We analyzed restricted strata of parental age in a 10-year California birth cohort to determine the independent or dependent effect from each parent. Autism cases from California Department of Developmental Services records were linked to State birth files (1990-1999). Only singleton births with complete data on parental age and education were included (n=4,947,935, cases=12,159). In multivariate logistic regression models, advancing maternal age increased risk for autism monotonically regardless of the paternal age. Compared with mothers 25-29 years of age, the adjusted odds ratio (aOR) for mothers 40+ years was 1.51 (95% CI: 1.35-1.70), or compared with mothers <25 years of age, aOR=1.77 (95% CI, 1.56-2.00). In contrast, autism risk was associated with advancing paternal age primarily among mothers <30: aOR=1.59 (95% CI, 1.37-1.85) comparing fathers 40+ vs. 25-29 years of age. However, among mothers >30, the aOR was 1.13 (95% CI, 1.01-1.27) for fathers 40+ vs. 25-29 years of age, almost identical to the aOR for fathers <25 years. Based on the first examination of heterogeneity in parental age effects, it appears that women's risk for delivering a child who develops autism increases throughout their reproductive years whereas father's age confers increased risk for autism when mothers are <30, but has little effect when mothers are past age 30. We also calculated that the recent trend towards delayed childbearing contributed approximately a 4.6% increase in autism diagnoses in California over the decade.

Abstract
BACKGROUND Early age of menarche (AOM) is associated with serious health problems including breast cancer and heart disease. Rising parental age at childbirth is associated with some adverse health outcomes in the offspring, but whether early menarche is one of them is not known. METHODS We studied a Danish cohort of singleton females (n = 3168) born in 1984-1987. Prenatal data were collected from mothers around 36th week of pregnancy (self-administered questionnaire), although the menarcheal age was collected from daughters aged 17-21 years in 2005 (Web-based questionnaire). We assessed each parental age association in separate linear regression models adjusted for covariates (socioeconomic status, parity, maternal pre-pregnancy BMI, marital status, maternal smoking and daughter's self-reported BMI), then included both ages in a third model. RESULTS Each year increase in maternal age showed a 9 day earlier onset of menarche in daughters [95% confidence interval (CI): -15.98, -2.90] and a 5 day earlier onset for each year increase in paternal age [95% CI: -10.85, 0.00], after adjusting for covariates. However, these associations attenuated when adjusted for the other parent [change in AOM in days: (i) maternal: -8.49 (95% CI: -17.09, 0.12), (ii) paternal: -1.14 (95% CI: -8.13, 5.84)]. CONCLUSIONS We found no significant association between parental age and AOM, but the small sample of advance aged parents (over 30 years) limits the information we have. Future studies with a larger sample or a sample with over-representation of older parents will be of value.

Abstract
OBJECTIVE To examine the association between maternal age, paternal age, and new-onset hypertension in late pregnancy. METHODS We carried out a retrospective cohort study of 9,302,675 pregnant women with live births in the United States between 1995 and 1998. Maternal and paternal ages were analyzed together using "couple age" in multivariate logistic regression models to reduce colinearity between maternal age and paternal age. The effect of paternal age was also analyzed with stratification of maternal age. RESULTS Compared with couples with both a maternal and paternal age of 20 to 34 years, an older maternal age (above 35 years) was associated with an increased risk for new-onset hypertension, except for couples with a very young father (below 20 years). Younger maternal age (below 20 years) was associated with a decreased risk for new-onset hypertension, except for couples with a very old father (above 45 years). There was no significant association between paternal age and new-onset hypertension with stratification of maternal age. CONCLUSION Increased risk for new-onset hypertension in late pregnancy is significantly associated with advancing maternal age, whereas there is no association between paternal age and new-onset hypertension in late pregnancy.

Abstract
There has been an increasing tendency to delay parenthood in developed countries in recent years, and there is not enough information available regarding the effect of this on fertility. The aim of this work was to determine the role of paternal age on the outcome of assisted reproduction. A retrospective study was designed comprising a total of 2204 intrauterine insemination (IUI) cycles, 1286 IVF cycles and 1412 IVF cycles with donated oocytes during the period 2000 to 2006. Male mean age was 34.3 years (range 25-56) for IUI, 34.8 years (range 19-62) for IVF and 41.10 years (range 25-71) for ovum donation cycles. Statistics revealed no differences regarding pregnancy and miscarriage rates when the results were compared among age groups. In standard IVF and ovum donation cycles there was no clear association between embryo quality and paternal age. There was no significant relationship between male age and implantation rate. So far this is the largest study concerning the relevance of male age in assisted reproduction. As confirmed by the present data, the effect of the age of the male in the range studied is irrelevant. This finding contributes to the information that can be provided to infertile couples.

Abstract
BACKGROUND Twins are exposed to intrauterine environments that differ significantly from those of singletons. These diverse environments might alter the risk for schizophrenia in twins and make it difficult to generalize from findings in twins when studying the risk of schizophrenia in the general population. Previous studies report contradictory findings on the risk for schizophrenia in twins. METHODS We studied the incidence of schizophrenia spectrum disorders, ascertained from Israel's National Psychiatric Registry, in a cohort of 2124 twins and 87,955 singletons. These offspring were followed from their birth in 1964-76 in the Jerusalem Perinatal study. Cox proportional hazards methods were used to compare outcomes over 28-41 years, adjusting for ages of parents. RESULTS Twins showed a relative risk [RR] of .84 relative to singletons, with a 95% confidence interval [CI] of (.51-1.4). RRs and CIs for males and females were .68 [.34-1.4] and 1.1 [.55-2.2] respectively. Twins in male-male, female-female or opposite-sex sets showed no significant variation in RRs; furthermore, first- or second-born twins did not differ significantly from each other. Siblings of twins had the same risk of schizophrenia as siblings of singletons. CONCLUSION Twins have the same risk for schizophrenia as the general population.

Abstract
OBJECTIVE To investigate whether incidence of twin deliveries is related to father's age, independently of mother's age, and whether it differs for same-sex or opposite-sex twin sets. STUDY DESIGN In a program of research on effects of paternal age, this study used data from a prospective cohort of 92,408 offspring born in Jerusalem from 1964 to 1976. Of the 91,253 deliveries in the Jerusalem Perinatal Study, 1115 were twin deliveries. The data were analyzed with General Estimate Equations to inform unconditional logistic regression. RESULTS After controlling for maternal age, odds ratios (ORs) and 95% confidence intervals (95% CI) associated with father's ages 25-34 and 35+ were 1.3 (1.1, 1.7) and 1.5 (1.2, 2.1) respectively, compared with fathers <25 years old. The effect of maternal age was partly explained by paternal age. The ORs for opposite-sex twin sets and male-male twin sets increased slightly with paternal age, while the OR for same-sex and female-female twin decreased. CONCLUSION Studies of twins are used to estimate effects of genes and environment in a variety of diseases. Our findings highlight the need to consider paternal as well as maternal age when analyzing data on twins to explore etiology of diseases.

Abstract
Despite much research, and clear improvement in our understanding of risk factors and pathogenetic mechanisms, the exact etiology of pre-eclampsia remains unknown. The immune maladaptation hypothesis has been challenged recently by several large epidemiological studies. One of the explanations for contradictory findings might be that the type of pre-eclampsia seen by obstetricians in developed countries mostly involves 30 and more years old, mildly obese pregnant women having near-term pre-eclampsia. It could be that this type of pre-eclampsia is primarily related to pre-existing maternal constitutional factors. This type of pre-eclampsia might be the dominant type of pre-eclampsia in the large Scandinavian and USA studies. In contrast, the epidemiology of pre-eclampsia in young women (age 15-25), so commonly seen in developing countries and certain lower socio-economic groups in developed countries, appears more in line with the immune maladaptation hypothesis. The aim here is to provide an updated review on studies supporting or challenging the immune maladaptation hypothesis.

Abstract
The Jerusalem Perinatal Study recorded information on population-based cohorts of 92 408 live- and stillbirths in 1964-76, and their parents, with active surveillance of infant deaths and birth defects. Data on maternal conditions, obstetric complications and interventions during labour and delivery were recorded for 92% of the births. Subsets were surveyed with antenatal interviews in 1965-68 (n = 11 467), paediatric admissions to hospital (n = 17 782) and postpartum interviews in 1975-76 (n = 16 912). Data from some offspring were linked to records of a health examination at age 17. The offspring, mothers and fathers have been traced recently, their vital status assessed, and the data linked to Israel's Cancer Registry and Psychiatric Registry. This paper describes the different types of data available, their sources, and some potential biases. Characteristics of this unique population are shown. Findings from the study are reviewed and a list of references is provided. The cohorts provide a unique source of data for a wide variety of studies.
