Abstract
OBJECTIVE To examine whether embryo biopsy for preimplantation genetic diagnosis (PGD) influences neonatal outcomes. DESIGN Prospective follow-up cohort. SETTING Tertiary university-affiliated medical center. PATIENT(S) 242 children born after PGD, 242 children born after intracytoplasmic sperm injection (ICSI) (158 singletons and 42 twins pairs in each group), and 733 children born after a spontaneous conception (SC) (493 singletons, 120 twins pairs), matched for maternal age, parity, and body mass index. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Gestational age, birth weight, prematurity (<37 and <34 weeks), low birth weight (<2,500 g, very low birth weight, <1,500 g), and intrauterine growth restriction (<10th percentile for gestational age). RESULT(S) For singletons, the mean birth weight was higher after SC compared with ICSI but not compared with PGD. Mean gestational ages were lower after PGD and ICSI compared with SC. The low birth weight and intrauterine growth restriction rates were 4.4%, 12.0%, and 5.7% and 5.1%, 9.5%, and 5.5% for PGD, ICSI, and SC, respectively. Similar results were found when controlled for the number of embryos transferred and cryopreservation. The results for twins exhibited similar but less statistically significant trends. Polar body and blastomere biopsies provided similar outcomes. CONCLUSION(S) Embryo biopsy itself did not cause intrauterine growth restriction or low birth weight compared with SC, despite lower gestational ages with PGD. The worsened outcomes in ICSI compared with PGD pregnancies may be due to the infertility itself.

Abstract
Preimplantation genetic diagnosis (PGD) is an option for couples at risk of having offspring with an inherited debilitating or fatal neurological disorder who wish to conceive a healthy child. PGD has been carried out for conditions with various modes of inheritance, including spinal muscular atrophy, Huntington disease, fragile X syndrome, and chromosomal or mitochondrial disorders, and for susceptibility genes for cancers with nervous system involvement. Most couples at risk of transmitting a genetic mutation would opt for PGD over prenatal testing and possible termination of a pregnancy. The aim of this Perspectives article is to assist neurologists in counselling and treating patients who wish to explore the option of PGD to enable conception of an unaffected child. PGD can be accomplished for most disorders in which the genetic basis is known, and we argue that it is time for clinicians and neurological societies to consider the evidence and to formulate guidelines for the responsible integration of PGD into modern preventative neurology.

Abstract
BACKGROUND Recent studies suggest that in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) are associated with suboptimal cardiometabolic outcome in offspring. It is unknown whether preimplantation genetic screening (PGS), which involves embryo biopsy, affects blood pressure (BP), anthropometrics, and the frequency of received medical care. METHODS In this prospective multicenter follow-up study, we assessed BP, anthropometrics, and received medical care of 4-y-old children born to women who were randomly assigned to IVF/ICSI with PGS (n = 49) or without PGS (controls; n = 64). We applied linear and generalized linear mixed-effects models to investigate possible effects of PGS. RESULTS BP in the PGS and control groups was similar: 102/64 and 100/64 mm Hg, respectively. Main anthropometric outcomes in the PGS vs. control group were: BMI: 16.1 vs. 15.8; triceps skinfold: 108 vs. 98 mm; and subscapular skinfold: 54 vs. 53 mm (all P values > 0.05). More PGS children than controls had received paramedical care (speech, physical, or occupational therapy: 14 (29%) vs. 9 (14%); P = 0.03 in multivariable analysis). The frequency of medicial treatment was comparable. CONCLUSION PGS does not seem to affect BP or anthropometrics in 4-y-old children. The higher frequency of received paramedical care after PGS may suggest an effect of PGS on subtle developmental parameters.

Abstract
BACKGROUND The increasing number of children conceived following preimplantation genetic diagnosis (PGD) necessitates the evaluation of their motor and cognitive development. The primary study objective was to evaluate the physical, developmental, and neurological outcome of children born after PGD in Greece. In addition, the secondary study objective was to compare the stress levels regarding parental roles between parents of PGD children and those of naturally conceived children. METHODS A cross-sectional study design was applied. The study population consisted of 31 children (aged 2 months to 7.5 years) born after PGD analysis and their parents. The developmental evaluation of children included a detailed physical evaluation and cognitive assessment with the Bayley Scales of Infant Development. The parent stress index was applied to evaluate comparative parental stress levels between those parents of PGD children and those of naturally conceived healthy children. RESULTS High rates of caesarean deliveries, increased incidence of prematurity, multiples and low-birth weight were observed among the 31 PGD children. Overall, 24 of the 31 PGD children had cognitive skills within normal range [general developmental quotient (GDQ): 86-115], while 6 children had lower levels of cognitive skills (GDQ<85). With regard to parental stress, PGD parents reported lower levels of parenting stress as compared to parents of naturally conceived children (P<0.01). CONCLUSIONS The enhanced frequency of poor cognitive and motor skills as well as low parental stress necessitates early detection and intervention for developmental delays among PGD children.

Abstract
Over 1000 children affected with cystic fibrosis (CF) are born annually in the USA. Since IVF with preimplantation genetic diagnosis (PGD) is an alternative to raising a sick child or to aborting an affected fetus, a cost-benefit analysis was performed for a national IVF-PGD program for preventing CF. The amount spent to deliver healthy children for all CF carrier-couples by IVF-PGD was compared with the average annual and lifetime direct medical costs per CF patient avoided. Treating annually about 4000 CF carrier-couples with IVF-PGD would result in 3715 deliveries of non-affected children at a cost of $57,467 per baby. Because the average annual direct medical cost per CF patient was $63,127 and life expectancy is 37 years, savings would be $2.3 million per patient and $2.2 billion for all new CF patients annually in lifetime treatment costs. Cumulated net saving of an IVF-PGD program for all carrier-couples for 37 years would be $33.3 billion. A total of 618,714 cumulative years of patients suffering because of CF and thousands of abortions could be prevented. A national IVF-PGD program is a highly cost-effective novel modality of preventive medicine and would avoid most births of individuals affected with debilitating genetic disease.

Abstract
OBJECTIVE The major objective of this study was to determine whether the embryo biopsy procedure might cause growth restriction or affect health outcome of children. STUDY DESIGN Auxological data and physical findings were compared at birth and age 2 for 102 children (70 singletons and 32 twins) born after PGD/PGS and 102 matched children born after intracytoplasmic sperm injection (ICSI) in a prospective study. RESULTS No statistically significant differences regarding weight, height and head circumference standard deviation scores (SDS) at birth and at age two years were observed. At two years of age the mean BMI SDS tended to be lower in PGD/PGS children (p=0.058). PGD/PGS babies had been more often breastfed (p=0.013), but mostly during a shorter time. The prevalence of major as well as minor congenital anomalies, hospital admissions and surgical interventions was similar. CONCLUSION Children born after embryo biopsy applied in PGD/PGS present similar prenatal and postnatal growth and health outcome in the first two years of life compared to ICSI children. Up till now, PGD and PGS appear not to be associated with a higher risk for health problems.

Abstract
BACKGROUND Preimplantation genetic diagnosis (PGD) and subsequently preimplantation genetic screening (PGS) have been introduced since 1990. The difference from the already existing in vitro fertilization (IVF) technology, using intracytoplasmic sperm injection (ICSI), was the embryo biopsy at day 3 after fertilization. Although healthy children post-PGD/PGS have been born, the question of whether embryo biopsy could have any harmful effects has to be studied on large series in a prospective manner. METHODS A prospective cohort study was undertaken from 1992 until 2005, using the same approach as for the follow-up of IVF and ICSI children conceived in the same centre. Questionnaires were sent to physicians and parents at conception and at delivery. Children were examined at 2 months of age by trained clinical geneticists whenever possible. RESULTS Data collected on 581 post-PGD/PGS children showed that term, birthweight and major malformation rates were not statistically different from that of 2889 ICSI children, with overall rates of major malformation among these post-PGD/PGS and ICSI children being 2.13 and 3.38%, respectively (odds ratio [OR]: 0.62; exact 95% confidence limits [95% CL]: 0.31-1.15). However, the overall perinatal death rate was significantly higher among post-PGD/PGS children compared with ICSI children (4.64 versus 1.87%; OR: 2.56; 95% CL: 1.54-4.18). When stratified for multiple births, perinatal death rates among PGD/PGS singleton and ICSI singleton children were similar (1.03 versus 1.30%; OR: 0.83; 95% CL: 0.28-2.44), but significantly more perinatal deaths were seen in post-PGD/PGS multiple pregnancies compared with ICSI multiple pregnancies (11.73 versus 2.54%; OR: 5.09; 95% CL: 2.80-9.90). The overall misdiagnosis rate was below 1%. CONCLUSIONS Embryo biopsy does not add risk factors to the health of singleton children born after PGD or PGS. The perinatal death rate in multiple pregnancies is such that both caution and long-term follow-up are required.

Abstract
Preimplantation genetic diagnosis is a form of very early prenatal diagnosis. The technique combines assisted reproductive technology with molecular genetics and cytogenetics to allow the identification of abnormalities in embryos prior to implantation. Since its introduction in 1990 this approach has been applied to an increasing number of single gene disorders, chromosomal rearrangements, and more recent indications such as aneuploidy screening and HLA matching. Since its inception the technology has attracted much attention: geneticists have expressed concerns about the robustness and validity of diagnosis based on single cell analysis, perinatologists were anxious about the effect of embryo biopsy on normal fetal development; and philosophers and ethicists have argued the cases for and against embryo selection. This article attempts to highlight the difficult choices and ethical challenges confronting patients and clinicians in an effort to balance the recognition of parental autonomy with the obligation of clinics to consider the welfare of any child born as a result of this treatment.

Abstract
Developments in biotechnology present difficult social and ethical challenges that need to be resolved by regulators among others. One crucial problem for regulators of new technologies is to ensure that regulation is both clear and sufficiently flexible to respond to new developments. This is particularly difficult to achieve in contentious fields such as medical biotechnology. In the European Union there is a divergence in the solutions to this problem which has lead to different regulatory frameworks for medical biotechnology. This paper compares and contrasts the British and Dutch regulatory frameworks for the selection of embryos by preimplantation genetic diagnosis as an example of the regulation of medical biotechnology. Some of the outcomes of the regulatory choices and possible reasons behind the divergent frameworks are discussed, such as the ethical outlooks and political systems in these countries.

Abstract
Pregnancies achieved by assisted reproduction technologies, particularly by intracytoplasmic sperm injection (ICSI) procedures, are susceptible to genetic risks inherent to the male population treated with ICSI and additional risks inherent to this innovative procedure. The documented, as well as the theoretical, risks are discussed in the present review study. These risks mainly represent that consequences of the genetic abnormalities underlying male subfertility (or infertility) and might become stimulators for the development of novel approaches and applications in the treatment of infertility. In addition, risks with a polygenic background appearing at birth as congenital anomalies and other theoretical or stochastic risks are discussed. Recent data suggest that assisted reproductive technology might also affect epigenetic characteristics of the male gamete, the female gamete, or might have an impact on early embryogenesis. It might be also associated with an increased risk for genomic imprinting abnormalities.

Abstract
Preimplantation genetic diagnosis (PGD) for single gene defects is described for a family in which each parent is a carrier of both Tay-Sachs (TS) and Gaucher disease (GD). A multiplex fluorescent polymerase chain reaction protocol was developed that simultaneously amplified all four familial mutations and 10 informative microsatellite markers. In one PGD cycle, seven blastomeres were analysed, reaching a conclusive diagnosis in six out of seven embryos for TS and in five out of seven embryos for GD. Of the six diagnosed embryos, one was wild type for both TS and GD, and three were wild type for GD and carriers of TS. Two remaining embryos were compound heterozygotes for TS. Two transferable embryos developed into blastocysts (wt/wt and wt GD/carrier TS) and both were transferred on day 5. This single cycle of PGD resulted in a healthy live child. Allele drop-out (ADO) was observed in three of 34 reactions, yielding an 8% ADO rate. The occurrence of ADO in single cell analysis and undetected recombination events are primary causes of misdiagnosis in PGD and emphasize the need to use multiple polymorphic markers. So far as is known, this is the first report of concomitant PGD for two frequent Ashkenazi Jewish recessive disorders.

Abstract
Early, rapid and reliable diagnosis is of first priority in prenatal medicine. The combination of specific sonographic markers (e.g. nuchal translucency) and biochemical parameters in maternal serum (e.g. free beta-human chorionic gonadotropin, pregnancy-associated plasma protein A), has already dramatically improved the sensitivity of non-invasive first trimester risk screening in pregnancy. In invasive prenatal diagnosis, in addition to well-established chorionic villi short-term culture, interphase multi-colour-fluorescence in situ hybridisation (M-FISH) on uncultured amnion cells has become a reliable tool for the rapid detection of fetal aneuploidies. Interphase M-FISH applications have enabled the diagnosis of selected chromosomal abnormalities in single cells and, therefore, have also become an important diagnostic tool for preimplantation diagnosis (PGD). The development of commercially available probe sets, in particular, has led to a broad use of interphase M-FISH in prenatal and PGD diagnosis.

Abstract
Preimplantation genetic aneuploidy screening performed by polar body biopsy has become a frequently used method, especially as in several countries only preconceptional genetic diagnosis is allowed. To penetrate the zona pellucida, mechanical, chemical and laser-assisted techniques have been introduced. In this paper, the advantages, disadvantages, efficacy and safety of these techniques are elucidated.

Abstract
The interface between assisted reproductive technologies (ART) and genetics comprises several sensitive and important issues that affect infertile couples, families with severe genetic diseases, potential children, professionals in ART and genetics, health care, researchers and the society in general. Genetic causes have a considerable involvement in infertility. Genetic conditions may also be transmitted to the offspring and hence create transgenerational infertility or other serious health problems. Several studies also suggest a slightly elevated risk of birth defects in children born following ART. Preimplantation genetic diagnosis (PGD) has become widely practiced throughout the world for various medical indications, but its limits are being debated. The attitudes towards ART and PGD vary substantially within Europe. The purpose of the present paper was to outline a framework for development of guidelines to be issued jointly by European Society of Human Genetics and European Society of Human Reproduction and Embryology for the interface between genetics and ART. Technical, social, ethical and legal issues of ART and genetics will be reviewed.

Abstract
Subfecundity is a frequent and serious problem that may sometimes be preventable, but we need to know more about its determinants. Different epidemiologic designs are available. The best of these use prospectively collected data from the population, but they are time consuming, expensive and often hampered by low-participation rates. Most patients undergoing infertility treatment are closely monitored for clinical reasons, making it feasible to use secondary data to study the period from conception to implantation and pregnancy. In spite that infertility patients are highly selected, there are specific exposure-effect relations that can be studied in cohorts of infertility patients. These patients offer a potentially useful setting for studying exposures that operate late in fertilization, whereas the designs may be inadequate to identify exposures that cause reduced sperm counts, anovulation and total occlusion. The clinical sampling and the treatment set limitations for what can be studied. In certain situations, infertile patients can, however, provide useful epidemiologic evidence for learning about the causes of subfecundity.

Abstract
Preimplantation genetic diagnosis for haemophilia offers couples at risk for transmitting the condition the opportunity to embark on a pregnancy knowing that the embryo is unaffected by the disease. The technique aims to increase the range of reproductive options available to these couples and remove the need for invasive prenatal diagnosis and the difficult decision on whether to terminate an affected pregnancy. This aims to reduce the anxiety associated with reproduction often seen in these couples. Patients undergo a cycle of in vitro fertilization followed by embryo biopsy. The single blastomeres are then analysed using fluorescent in situ hybridization to detect the sex of the embryo, and only female embryos are transferred to the uterus. Recently a PCR based approach has allowed specific mutation detection, and therefore the transfer of unaffected male and female embryos.

Abstract
Preimplantation genetic diagnosis (PGD) was introduced at the beginning of the 1990s as an alternative to prenatal diagnosis, to prevent termination of pregnancy in couples with a high risk for offspring affected by a sex-linked genetic disease. At that time, embryos obtained in vitro were tested to ascertain their sex, and only female embryos were transferred. Since then, techniques for genetic analysis at the single-cell level, involving assessment of first and second polar bodies from oocytes or blastomeres from cleavage-stage embryos, have evolved. Fluorescence in-situ hybridisation (FISH) has been introduced for the analysis of chromosomes and PCR for the analysis of genes in cases of monogenic diseases. In-vitro culture of embryos has also improved through the use of sequential media. Here, we provide an overview of indications for, and techniques used in, PGD, and discuss results obtained with the technique and outcomes of pregnancies. A brief review of new technologies is also included.

Abstract
Ongoing trends in prenatal diagnosis aim at early, rapid, and ideally noninvasive diagnosis as well as at the improvement of risk-screening for aneuploidy. Interphase-fluorescence in situ hybridization and quantitative fluorescence polymerase chain reaction are efficient tools for the rapid exclusion of selected aneuploidies in addition to the established direct preparation of chromosomes from chorionic villi. Interphase fluorescence in situ hybridization has also made possible the diagnosis of selected chromosome abnormalities in single cells (e.g. in preimplantation genetic diagnosis) or noninvasive diagnosis. More complex multicolor fluorescence in situ hybridization approaches are currently being evaluated. Single cell polymerase chain reaction is the key technique for the molecular diagnosis of a growing number of monogenic conditions before implantation or, still more experimental, in fetal cells retrieved from the maternal circulation. New sources for noninvasive diagnosis came into play such as fetal DNA or cell nuclei in maternal plasma. The combination of biochemical parameters in the maternal serum, namely free beta-human chorionic gonadotropin with pregnancy associated plasma protein A and sonographic markers, has already dramatically increased the sensitivity of risk screening in the first trimester of pregnancy.

Abstract
Today, preimplantation genetic diagnosis (PGD) is offered in over 40 centres worldwide for an expanded range of genetic defects causing disease. This very early form of prenatal diagnosis involves the detection of affected embryos by fluorescent in situ hybridization (FISH) (sex determination or chromosomal defects) or by polymerase chain reaction (PCR) (monogenic diseases) prior to implantation. Genetic analysis of the embryos involves the removal of some cellular mass from the embryos (one or two blastomeres at cleavage-stage or some extra-embryonic trophectoderm cells at the blastocyst stage) by means of an embryo biopsy procedure. Genetic analysis can also be performed preconceptionally by removal of the first polar body. However, additional information is then often gained by removal of the second polar body and/or a blastomere from the embryo. Removal of polar bodies or cellular material from embryos requires an opening in the zona pellucida, which can be created in a mechanical way (partial zona dissection) or chemical way (acidic Tyrode's solution). However, the more recent introduction of laser technology has facilitated this step enormously. Different biopsy procedures at different preimplantation stages are reviewed here, including their pros and cons and their clinical applications. The following aspects will also be discussed: safety of zona drilling by laser, use of Ca2+/Mg2+-free medium for decompaction, and removal of one or two cells from cleavage-stage embryos.
