Abstract
PURPOSE The trend of delaying childbirth has resulted in a growing number of advanced-aged women who are opting for preimplantation genetic testing (PGT) to screen for monogenic diseases or structural chromosomal rearrangements (PGT-M and PGT-SR). This increase in demand necessitates the development of a clinical predictive model for live birth outcomes in these women. Therefore, the objective of this study is to construct a comprehensive predictive model that assesses the likelihood of achieving a successful live birth in advanced-aged women undergoing PGT-M and PGT-SR treatments. METHODS A retrospective cohort study of 37-45-year-old women undergoing preimplantation genetic testing for monogenic disease or structural chromosomal rearrangement cycles from 2010 to 2021 was conducted at a university hospital reproductive centre. The purpose was to develop a clinical predictive model for live birth in these women. The main outcome studied was the cumulative live birth rate in the first or subsequent cycles. Developing a decision tree enabled a comprehensive study of clinical parameters and expected outcomes. RESULTS The analysis included 158 women undergoing 753 preimplantation genetic testing cycles. The cumulative live birth rate was 37.342% (59/158). Decision tree analysis revealed that women aged ≤ 40.1 or women > 40.1 with one or more top-quality transferable embryos in their first cycle had the best chance for a live baby (56% and 41%, respectively). Those older than 40.1 without top-quality embryos and seven or fewer dominant follicles had no live births. A Kaplan-Meier curve showed that for autosomal dominant diseases, there was a negligible increase in live birth rate after three cycles, compared to six cycles in autosomal recessive inheritance. CONCLUSION In older women, the chance of delivering after repeated cycles is higher in those with at least one top-quality unaffected embryo in their first preimplantation genetic testing cycle. Additional preimplantation genetic testing cycles after three in carriers of an autosomal dominant disorder and six in those with an autosomal recessive disorder should be considered prudently.

Abstract
BACKGROUND Preimplantation genetic testing (PGT) includes methods that allow embryos to be tested for severe inherited diseases or chromosomal abnormalities. In addition to IVF/ICSI and repeated freezing and thawing of the embryos, PGT requires a biopsy to obtain embryonic genetic material for analysis. However, the potential effects of PGT on obstetric and neonatal outcomes are currently uncertain. OBJECTIVE AND RATIONALE This study aimed to investigate whether pregnancies conceived after PGT were associated with a higher risk of adverse obstetric and neonatal outcomes compared with spontaneously conceived (SC) pregnancies or pregnancies conceived after IVF/ICSI. SEARCH METHODS PubMed, EMBASE, MEDLINE, Web of Science and The Cochrane Library entries from January 1990 to January 2021 were searched. The primary outcomes in this study were low birth weight (LBW) and congenital malformations (CMs), and the secondary outcomes included gestational age, preterm delivery (PTD), very preterm delivery (VPTD), birth weight (BW), very low birth weight (VLBW), neonatal intensive care unit (NICU) admission, hypertensive disorders of pregnancy (HDP), gestational diabetes, placenta previa and preterm premature rupture of membranes (PROM). We further pooled the results of PGT singleton pregnancies. Subgroup analyses included preimplantation genetic diagnosis (PGD), preimplantation genetic screening (PGS), cleavage-stage biopsy combined with fresh embryo transfer (CB-ET) and blastocyst biopsy combined with frozen-thawed embryo transfer (BB-FET). OUTCOMES This meta-analysis included 15 studies involving 3682 babies born from PGT pregnancies, 127 719 babies born from IVF/ICSI pregnancies and 915 222 babies born from SC pregnancies. The relative risk (RR) of LBW was higher in PGT pregnancies compared with SC pregnancies (RR = 3.95, 95% confidence interval [CI]: 2.32-6.72), but the risk of CMs was not different between the two groups. The pooled results for the risks of LBW and CMs were similar in PGT and IVF/ICSI pregnancies. The risks of PTD (RR = 3.12, 95% CI: 2.67-3.64) and HDP (RR = 3.12, 95% CI: 2.18-4.47) were significantly higher in PGT pregnancies compared with SC pregnancies. Lower gestational age (mean difference [MD] = -0.76 weeks, 95% CI -1.17 to -0.34) and BW (MD = -163.80 g, 95% CI: -299.35 to -28.24) were also noted for PGT pregnancies compared with SC pregnancies. Nevertheless, compared with IVF/ICSI pregnancies, the risks of VPTD and VLBW in PGT pregnancies were significantly decreased by 41% and 30%, respectively, although the risk of HDP was still significantly increased by 50% in PGT pregnancies compared with IVF/ICSI pregnancies. The combined results of obstetric and neonatal outcomes of PGT and IVF/ICSI singleton pregnancies were consistent with the overall results. Further subgroup analyses indicated that both PGD and PGS pregnancies were associated with a higher risk of PTD and a lower gestational age compared with SC pregnancies. WIDER IMPLICATIONS This meta-analysis showed that PGT pregnancies may be associated with increased risks of LBW, PTD and HDP compared with SC pregnancies. The overall obstetric and neonatal outcomes of PGT pregnancies are favourable compared with those of IVF/ICSI pregnancies, although PGT pregnancies were associated with a higher risk of HDP. However, because the number of studies that could be included was limited, more randomised controlled trials and prospective cohort studies are needed to confirm these conclusions.

Abstract
STUDY QUESTION What is the likelihood of success of a single cycle of preimplantation genetic testing for monogenic disorders (PGT-M), measured as the cumulative live birth rate (CLBR) and based on various patient demographics? SUMMARY ANSWER For all women aged ≤40 years, the CLBR was at least 10% when the number of oocytes was ≥7 (range 10-30%) or was at least 5% when the number of oocytes was ≥3 (range 5-17%). WHAT IS KNOWN ALREADY The number of oocytes is significantly associated with the number of embryos for genetic testing and the clinical outcome in PGT-M. Embryos diagnosed as affected or embryos that remain without diagnosis cannot be used for embryo transfer. The size of the group of embryos non-suitable for transfer varies between 25% and 81%, depending on the indication. Thus, PGT-M is more likely to be more severely impacted by suboptimal ovarian response, poor fertilization and suboptimal embryo development than conventional IVF/ICSI schemes without PGT. STUDY DESIGN, SIZE, DURATION This was a single-centre retrospective comparative cohort study, of cycles between January 2011 and December 2015. A total number of 2265 PGT-M cycles were compared to 2833 conventional ICSI cycles. The principal aim of our study was the identification of the parameters of poor CLBR in couples undergoing PGT-M using multiplex short tandem repeat (STR) markers on blastomere biopsy DNA. The secondary aim was to compare the parameters of poor CLBR of the PGT-M population to those of couples undergoing ICSI without PGT. PARTICIPANTS/MATERIALS, SETTING, METHODS The baseline characteristics of the PGT-M group were compared to the conventional ICSI group. A multiple regression analysis was applied to account for the following potential confounding factors: female age, number of previous ART cycles, number of oocytes/suitable embryos for transfer and dosage of gonadotrophins used for ovarian stimulation. MAIN RESULTS AND THE ROLE OF CHANCE The PGT-M group was younger (female age 32.0 vs 34.5 years), had a higher number of previous ART cycles (1.1 vs 0.9 cycles) and used more gonadotrophins (2367 vs 1984 IU). Per cycle, the PGT-M group had more retrieved oocytes (11.8 vs 8.3 oocytes), fewer suitable embryos for transfer (1.7 vs 2.8 embryos) and a lower CLBR (29.4% vs 35.0%). Multiple regression analysis showed that the CLBR in the PGT-M group was significantly influenced by female age, the number of previous ART cycles, the number of oocytes and the dose of ovarian stimulation. In both groups, the predicted CLBR increased with increasing numbers of oocytes and suitable embryos. At least two retrieved oocytes or one embryo per single PGT-M cycle could confer an estimated CLBR above 10%. By assessing female age and the number of retrieved oocytes together, it was shown that for all women aged ≤40 years, the predicted CLBR per single PGT-M cycle was ≥10% when the number of oocytes was ≥7 or was ≥5% when the number of oocytes was ≥3. LIMITATIONS, REASONS FOR CAUTION Despite the large sample size, the findings are confined by limited confounder adjustment and the lack of specific PGT-M comparators. WIDER IMPLICATIONS OF THE FINDINGS This study aimed to describe the likelihood of success of PGT-M treatment, measured as CLBR, based on various patient demographics. In a PGT-M program, couples need to be informed of the prognosis more specifically when it is futile. The table of predicted CLBRs presented in this study is a useful tool in counselling PGT-M couples for making reproductive choices.

Abstract
Preimplantation genetic diagnosis (PGD) was introduced in the late 1980s and represents an option for couples at risk of transmitting an inherited, debilitating or neurological disorder to their children. From a cleavage or blastocyst stage embryo, cell(s) are collected and then genetically analyzed for disease; enabling an unaffected embryo to be transferred into the uterus cavity. Nowadays, PGD has been carried out for several hundreds of heritable conditions including myotonic dystrophy, and for susceptibility genes involved in cancers of the nervous system. Currently, advanced molecular technologies with better resolution, such as array comparative genomic hybridisation, quantitative polymerase chain reaction, and next generation sequencing, are on the verge of becoming the gold standard in embryo preimplantation screening. Given this, it may be time for neurological societies to consider the published evidence to develop new guidelines for the integration of PGD into modern preventative neurology. Therefore, the main aim of this review is to illustrate the option of PGD to enable conception of an unaffected baby, and to assist clinicians and neurologists in the counseling of the patient at risk of transmitting an inherited disease, to explore the genetic journey throughout in vitro fertilization IVF with PGD.

Abstract
Technological advances in genetic testing have enabled prospective parents to learn about their risk of passing a genetic condition to their future children. One option for those who want to ensure that their biological children do not inherit a genetic condition is to create embryos through in vitro fertilisation (IVF) and use a technique called preimplantation genetic testing (PGT) to screen embryos for genetic abnormalities before implantation. Unfortunately, due to its high cost, IVF-with-PGT is out of reach for the vast majority of Americans. This article addresses an issue that has been underexplored in the medical ethics literature: the lack of insurance coverage for IVF-with-PGT.Within the US system, a key concept in insurance is that of medically necessary care, which broadly consists of diagnostic services and treatment services. In this article, I argue that IVF-with-PGT could be classified as either a diagnostic service or as a treatment service. To make this case, I show that IVF-with-PGT is similar to other types of services that are often covered by US insurance providers. In light of these similarities, I argue that the current system is inconsistent with respect to what is-and is not-covered by insurance. To promote consistency and fairness in coverage, like cases should be treated alike-starting with greater coverage for IVF-with-PGT.

Abstract
STUDY QUESTION What are the factors influencing the success rate for couples undergoing preimplantation genetic testing (PGT) for polycystic kidney disease (PKD)? SUMMARY ANSWER In our study cohort, the live birth delivery rate is significantly associated with female age while the male infertility accompanying autosomal dominant PKD (ADPKD) does not substantially affect the clinical outcome. WHAT IS KNOWN ALREADY While women with ADPKD have no specific fertility problems, male ADPKD patients may present with reproductive system abnormalities and infertility. STUDY DESIGN, SIZE, DURATION This retrospective cohort study involves 91 PGT cycles for PKD for 43 couples (33 couples for PKD1, 2 couples for PKD2 and 8 couples for autosomal recessive PKD (ARPKD)) from January 2005 until December 2016 with follow-up of transfers until end of 2017. PARTICIPANTS/MATERIALS, SETTING, METHODS Sixteen single-cell clinical tests for PKD based on multiplex PCR of short tandem repeat markers, with or without a specific mutation were developed and applied for diagnosis of 584 Day 3 cleavage stage embryos. In 18 couples, the male partner was affected with ADPKD (=Group A) and 12 of them had a documented infertility status. Group A underwent 52 cycles to oocyte retrieval. For 18 other couples, the female partner was affected with ADPKD (=Group B) and four male partners from this group had a documented history of infertility. This group underwent 31 cycles to OR. MAIN RESULTS AND THE ROLE OF CHANCE Genetic analysis resulted in 545 embryos (93.3%) with a diagnosis, of which 215 (36.8%) were genetically transferable. Transfer of 74 embryos in 53 fresh cycles and of 34 cryopreserved embryos in 33 frozen-warmed embryo transfer cycles resulted in a live birth delivery rate of 38.4% per transfer with 31 singleton live births, two twin live births and one ongoing pregnancy. The observed cumulative delivery rate was 57.8% per couple after five treatment cycles. Thirty cryopreserved embryos still remain available for transfer. The clinical pregnancy rate per transfer (fresh + frozen; 45.9% in group A versus 60.0% in group B, P < 0.05) and the live birth delivery rate per transfer (fresh + frozen; 27.0% in group A versus 42.9% in group B, P < 0.05) was significantly lower for couples with the male partner affected with ADPKD compared with couples with the female partner affected with ADPKD. However, a multivariate logistic regression analysis showed that only female age was associated with live birth delivery rate (odds ratio = 0.87; 95% CI: 0.77-0.99; P = 0.032). LIMITATIONS, REASONS FOR CAUTION This study is based on retrospective data from a single centre with Day 3 one-cell and two-cell biopsy. Further analysis of a larger cohort of PKD patients undergoing PGT is required to determine the impact of male infertility associated with ADPKD on the cumulative results. WIDER IMPLICATIONS OF THE FINDINGS Knowledge about factors affecting the clinical outcome after PGT can be a valuable tool for physicians to counsel PKD patients about their reproductive options. Males affected with ADPKD who suffer from infertility should be advised to seek treatment in time to improve their chances of conceiving a child. STUDY FUNDING/COMPETING INTEREST(S) No funding was obtained. There are no competing interests to declare. TRIAL REGISTRATION NUMBER Not applicable.

Abstract
Men and women with a hereditary genetic disease are faced with different options when they wish to become parents. One is pre-implantation genetic diagnosis (PGD) which is a combination of in vitro fertilization (IVF) and genetic analysis of the embryo before implantation. The present study focused on men and women's psychological experiences of PGD three years after applying for PGD. Nineteen women and seventeen men (i.e. seventeen couples and two women) participated. The interviews were analysed by thematic method. It is better to have tried was identified as a master theme, under which came three underlying sub-themes, which had the following headings: Practical experience of PGD, Psychological experience of PGD and Goals of PGD. The results show that men and women three years after PGD are still psychologically affected by their experience. The men and women raised concerns that their relationship had been affected, both positively and negatively, and feelings of anxiety and depression still remained. Healthcare services should recognize the heterogeneous nature of the group being studied and therefore the need for counselling can arise at different times and in relation to different areas, regardless of the outcome of the PGD.

Abstract
Purpose This study aims to test the hypothesis, in a single-center retrospective analysis, that live birth rates are significantly different when utilizing preimplantation genetic screening (PGS) compared to not utilizing PGS in frozen–thawed embryo transfers in our patients that use eggs from young, anonymous donors. The question therefore arises of whether PGS is an appropriate intervention for donor egg cycles. Methods Live birth rates per cycle and live birth rates per embryo transferred after 398 frozen embryo transfer (FET) cycles were examined from patients who elected to have PGS compared to those who did not. Blastocysts derived from donor eggs underwent trophectoderm biopsy and were tested for aneuploidy using array comparative genomic hybridization (aCGH) or next-generation sequencing (NGS), then vitrified for future use (test) or were vitrified untested (control). Embryos were subsequently warmed and transferred into a recipient or gestational carrier uterus. Data was analyzed separately for single embryo transfer (SET), double embryo transfer (DET), and for own recipient uterus and gestational carrier (GC) uterus recipients. Results Rates of implantation of embryos leading to a live birth were significantly higher in the PGS groups transferring two embryos (DET) compared to the no PGS group (GC, 72 vs. 56 %; own uterus, 60 vs. 36 %). The live birth implantation rate in the own uterus group for SET was higher in the PGS group compared to the control (58 vs. 36 %), and this almost reached significance but the live birth implantation rate for the SET GC group remained the same for both tested and untested embryos. Live births per cycle were nominally higher in the PGS GC DET and own uterus SET and DET groups compared to the non-PGS embryo transfers. These differences almost reached significance. The live birth rate per cycle in the SET GC group was almost identical. Conclusions Significant differences were noted only for DET; however, benefits need to be balanced against risks associated with multiple pregnancies. Results observed for SET need to be confirmed on larger series and with randomized cohorts.

Abstract
Objective: To assess the probability of finding at least one euploid embryo (POE) and euploidy rate in preimplantation genetic screening (PGS) cycles for aneuploidy testing with fluorescent in situ hybridization (FISH) and array comparative genomic hybridization (aCGH) based on the number of retrieved oocytes after adjustment for age. Design: Retrospective data analysis. Setting: Private in vitro fertilization center in a general hospital, Istanbul, Turkey. Patient(s): In this study, 1412 couples with 1739 cycles were included. Intervention(s): Embryo biopsy at cleavage stage or trophectoderm biopsy analyzed by FISH or aCGH techniques. Main outcome measure(s): Probability of finding at least one euploid embryo for transfer and euploidy rate according to retrieved oocytes after adjustment for age. Result(s): Estimated probabilities of finding at least one euploid embryo were plotted based on age and number of retrieved oocytes. When controlled for age, the POE increased with each additional oocyte retrieved (OR 1.11, 95% CI 1.08–1.14), but the euploidy rate did not. When retrieved oocytes were subgrouped, we found that the odds of finding at least one euploidy embryo were highest when 16–20 oocytes were retrieved compared to 1–5 oocytes with both FISH (OR 8.62, 95% CI 4.67–15.93) and aCGH (OR 2.78, 95% CI 1.07–7.21). However, the chances did not increase with the retrieval of more than 20 oocytes. Conclusion(s): The estimated probabilities of finding at least one transferrable embryo would enable more accurate counselling of patients based on age and the number of retrieved oocytes. As the highest estimates for finding one euploidy embryo were achieved with 15-20 oocytes, deciding the best protocol for ovarian stimulation to achieve the maximum number of oocytes for retrieval based on the patients age and ovarian reserve would be of crucial importance.

Abstract
To evaluate the impact of thalassemia carrier status on the response to controlled ovarian stimulation (COS) and outcome of intracytoplasmic sperm injection (ICSI). Seventy couples that both carried a mutation attributed to thalassemia (PGD group) and 57 couples in which only the father was a thalassemia carrier (CON group) were enrolled. All female subjects received long protocol GnRH agonist stimulation and received equivalent doses of recombinant follicle-stimulating hormone and the number of retrieved oocytes and utilisable embryos did not differ significantly. The endometrial thickness at human chorionic gonadotropin (hCG) administration day and the number of transferable embryos was lower in the PGD groups. However, pregnancy outcomes, including the clinical pregnancy rate and ongoing pregnancy rate, did not differ significantly between the two groups per cycle. Ovarian response to COS is not impaired by maternal thalassemia carrier status and embryo biopsy did not impair preimplantation embryo development or pregnancy outcomes.

Abstract
Purpose The aim of this study was to explore factors contribute to the success of PGD cycles for monogenic diseases. Methods During a 3-year period (January 2009 to December 2012), 184 consecutive ICSI-PGD cycles for monogenic diseases reaching the ovum pick-up and fresh embryo-transfer stage performed at the Reproductive Medicine Center of The First Affiliated Hospital Of Sun Yat-sen University were evaluated. Results ICSI was performed on 2206 metaphase II oocytes, and normal fertilization and cleavage rates were 83.4% (1840/2206) and 96.2% (1770/1840), respectively. In the present study, 60.5% (181/299) of day 3 good-quality embryos developed into good-quality embryos on day 4 after biopsy. Collectively, 42.9% clinical pregnancy rate (79/184) and 28.5% implantation rate (111/389) were presented. In the adjusted linear regression model, the only two significant factors affecting the number of genetically unaffected embryos were the number of biopsied embryos (coefficient: 0.390, 95%CI 0.317–0.463, P = 0.000) and basal FSH level (coefficient: 0.198, 95%CI 0.031–0.365, P = 0.021). In the adjusted binary logistic regression model, the only two significant factors affecting pregnancy outcome were the number of genetically available transferable embryos after PGD (adjusted OR 1.345, 95% CI 1.148–1.575, P = 0.000) and number of oocyte retrieved (adjusted OR 0.934, 95% CI 0.877–0.994, P = 0.031). Conclusion There should be at least four biopsied embryos to obtain at least one unaffected embryos in a PGD system for patients with single gene disorder and under the condition of basal FSH level smaller than 8.0mmol/L. Moreover, if only a low number (< 4) of biopsied embryos are available on day 3, the chance of unaffected embryos for transfer was small, with poor outcome.

Abstract
This is a retrospective study aimingto clarify the current status of preimplantation genetic diagnosis (PGD) in Japan. Our data were
collected from 12 facilities between September 2004 and September 2012, and entered into a database. A majority of PGD in Japan
was performed for balanced structural chromosomal abnormalities in couples with recurrent miscarriage. PGD for monogenic
diseases was performed only in two facilities. The average maternal age was 38 years for monogenic diseases and 40 years for
chromosomal abnormalities. Overall there have been671 cycles to oocyte retrieval reported. Of these cycles, 85% (572 cycles)were
for chromosomal abnormalities, and 15% (99 cycles) for monogenic diseases. Diagnosis rates in the current study were 70.8% for
monogenic diseases and 94.0% for chromosomal abnormalities. Rates of embryo transfer of PGD were 62.7% for monogenic
diseases and 25.5% for chromosomal abnormalities. Clinical pregnancy rates per embryo transfer were 12.0% for monogenic
diseases and 35.6% for chromosomal abnormalities. Our study is the first PGD report from all facilities which had the approval of
the ethics committee of the Japanese Society of Obstetrics and Gynecology. We have built a basis for gathering continuous PGD
data in Japan.

Abstract
THREE TYPES OF HEREDITARY ANGIOEDEMA (HAE) HAVE BEEN DESCRIBED two are due to C1 inhibitor (C1-INH) deficiency (C1-INH-HAE types I and II) and one is characterized by normal C1-INH (nC1-INH-HAE). The management of pregnancy in patients with HAE is often a clinical challenge owing to potential worsening of the disease in relation to the physiological increase in estrogens and the limited treatment options. This review addresses the potential influence of pregnancy on the clinical severity of hereditary angioedema and the management of this disease during pregnancy with currently available treatments.

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
IVF productivity rate is an index defined as the sum of all live births from either fresh or frozen embryo transfers arising from a single oocyte collection. This retrospective analysis over 9 continuous years used this index to understand the potential impact on pregnancy rates of milder stimulation regimens with associated reduced egg numbers. The productivity rate per collection increased in a linear and significant rate as more oocytes were recovered, more embryos frozen and more frozen embryo transfers contributed to pregnancy. This observation was true for women aged <35 years and less so for women aged 35-39 years but not for women aged 40 years and older. The contribution of frozen embryo transfer to the productivity rate rose in a linear manner, reaching over 40% of all live births with nine oocytes. The number of live births per oocyte, pronuclear embryos and thawed embryos decreased significantly but the number of live births per embryo transferred (fresh or frozen) rose with rising oocyte numbers, reflecting increasing opportunity for embryo selection. This study suggests that optimal benefits with minimal risks are gained from a model that includes both fresh and frozen transfers under stimulation generating between 8 and 12 eggs.

Abstract
BACKGROUND/PURPOSE Patients with chromosomal translocation are highly vulnerable to produce unbalanced gametes that result in recurrent miscarriages, affected offspring, or infertility. Preimplantation genetic diagnosis (PGD) with blastomere biopsy and fluorescent in-situ hybridization (FISH) has been used to select normal/balanced embryos for transfer. However, FISH is inherent with some technical difficulties such as cell fixation and signal reading. Here we introduce a strategy of PGD using blastocyst biopsy and array comparative genomic hybridization (aCGH) for reproductive problems of patients with chromosomal translocation. METHODS Twelve patients diagnosed as having chromosomal translocation who underwent PGD cycles were included in this single-center observational study. Blastocyst biopsy was performed and biopsied blastocysts were cryopreserved individually. Testing was performed with aCGH, and the euploid embryos were transferred in the following thawing cycles. RESULTS The overall diagnostic efficiency was 90.2% (55/61) and the euploidy rate was 32.7% (18/55). Ten cycles of thawed embryo transfer (ET) were carried out, resulting in three live births and another three ongoing pregnancies with an ongoing pregnancy rate of 60%/transfer cycle. The prenatal diagnosis with chorionic villi sampling confirmed the results of PGD/aCGH in all six pregnant women. No miscarriage happened in our case series. CONCLUSION Our study demonstrates an effective PGD strategy with promising outcomes. Blastocyst biopsy can retrieve more genetic material and may provide more reliable results, and aCGH offers not only detection of chromosomal translocation but also more comprehensive analysis of 24 chromosomes than traditional FISH. More cases are needed to verify our results and this strategy might be considered in general clinical practice.

Abstract
BACKGROUND Huntington's disease (HD) is an autosomal dominant neurodegenerative late onset disorder. This review of reproductive options aims to increase reproductive confidence and to prevent suffering in relation to family planning around HD and possibly other late onset neurodegenerative disorders. METHODS Selected relevant literature and own views and experiences as clinical geneticists, psychologists and ethicists have been used. RESULTS Possible options, with emphasis on prenatal diagnosis (PD) and preimplantation genetic diagnosis (PGD) to prevent the transmission of HD to the next generation, are described and discussed. They are formally presented in a decision tree, taking into account the presence or absence of a fully penetrant allele (FPA), a reduced penetrant allele (RPA) or an intermediate allele (IA). A table compares invasive and non-invasive PD and PGD. From a psychological perspective, the complex process of counselling and decision-making regarding reproductive options is discussed. Special attention is paid to the decision to avoid the transmission of the mutation and to the confrontation and coping of a mutation-free child growing up with a parent developing disease symptoms. From an ethical point of view, reflections on both PD and PGD are brought forward taking into account the difference between FPA, RPA and IA, direct testing or exclusion testing and taking into account the welfare of the child in the context of medically assisted reproduction. CONCLUSION Recommendations and suggestions for good clinical practice in the reproductive care for HD families are formulated.

Abstract
Carriers of reciprocal translocations (rcp) are known to be at risk for reproductive difficulties. Preimplantation genetic diagnosis (PGD) is one of the options these carriers have to try in order to fulfil their desire to have a child. In the present study, we retrospectively looked at the results of 11 years (1997-2007) of PGD for rcp in our center to improve the reproductive counseling of these carriers. During this period 312 cycles were performed for 69 male and 73 female carriers. The mean female age was 32.8 years, the mean male age 35.8 years. Most carriers were diagnosed with a translocation because of fertility problems or recurrent miscarriages, and most of them opted for PGD to avoid these problems. In 150 of the 312 cycles, embryo transfer (ET) was feasible and 40 women had a successful singleton or twin pregnancy. This gives a live birth delivery rate of 12.8% per started cycle and of 26.7% per cycle with ET. Owing to the large number of abnormal embryos, PGD cycles for rcp often lead to cancellation of ET, explaining the low success rate when expressed per cycle with oocyte pick-up. Once ET was feasible, the live birth delivery rate was similar to that of PGD in general at our center. PGD is therefore an established option for specific reciprocal translocation carriers.

RESULT(S) Of 190,260 fresh, nondonor assisted reproductive technology (ART) cycles reported to SART CORS in 2007-2008, 8,337 included PGT. Of 6,971 cycles with a defined indication, 1,382 cycles were for genetic diagnosis, 3,645 for aneuploidy screening (PGS), 527 for translocation, and 1,417 for elective sex election. Although the total number of fresh, autologous cycles increased by 3.6% from 2007 to 2008, the percentage of cycles with PGT decreased by 5.8% (4,293 in 2007 and 4,044 in 2008). As a percentage of fresh, nondonor ART cycles, use dropped from 4.6% (4,293/93,433) in 2007 to 4.2% (4,044/96,827) in 2008. The primary indication for PGT was PGS: cycles performed for this indication decreased (-8.0%). PGD use for single-gene defects (+3.2%), elective sex selection (+5.3%), and translocation analysis (+0.5%) increased. PGT usage varied significantly by geographical region. CONCLUSION(S) PGT usage in the United States decreased between 2007 and 2008 owing to a decrease in PGS. Use of elective sex selection increased. High transfer cancellation rates correlated with reduced live-birth rates for some PGT indications.

Abstract
Preimplantation human leukocyte antigen (HLA) typing allows the birth of healthy children who are potential donors of stem cells for their affected siblings. This technique can be used for acquired diseases such as leukaemia or can be used for single-gene disorders such as thalassaemia. This retrospective study presents clinical data obtained from 171 couples who had undergone 327 preimplantation HLA typing cycles: 262 cycles for HLA typing in combination with mutation analysis and 65 cycles for the sole purpose of HLA typing. Of the diagnosed embryos 17.6% were found to be HLA matched. Embryo transfer was performed in 212 cycles, 34.9% clinical pregnancy rate per transfer was achieved and 59 healthy and HLA-compatible children were born. Twenty-one sick children have been cured through haemopoietic stem cell transplantation. The effect of maternal age and ovarian reserve on reproductive outcome was assessed retrospectively. The data demonstrated that, once a mutation-free and HLA-compatible embryo was found, clinical pregnancy rate did not differ statistically significantly despite the presence of some cycle-related limitations such as advanced maternal age and/or diminished ovarian reserve. Preimplantation HLA typing is an effective therapeutic tool for curing an affected sibling even for poor-prognosis patients.

Abstract
BACKGROUND Fluorescence in situ hybridization (FISH) is the most widely used method for detecting unbalanced chromosome rearrangements in preimplantation embryos but it is known to have several technical limitations. We describe the clinical application of a molecular-based assay, array comparative genomic hybridization (array-CGH), to simultaneously screen for unbalanced translocation derivatives and aneuploidy of all 24 chromosomes. METHODS Cell biopsy was carried out on cleavage-stage embryos (Day 3). Single cells were first lysed and DNA amplified by whole-genome amplification (WGA). WGA products were then processed by array-CGH using 24sure + arrays, BlueGnome. Balanced/normal euploid embryos were then selected for transfer on Day 5 of the same cycle. RESULTS Twenty-eight consecutive cycles of preimplantation genetic diagnosis were carried out for 24 couples carrying 18 different balanced translocations. Overall, 187/200 (93.5%) embryos were successfully diagnosed. Embryos suitable for transfer were identified in 17 cycles (60.7%), with transfer of 22 embryos (mean 1.3 ± 0.5). Twelve couples achieved a clinical pregnancy (70.6% per embryo transfer), with a total of 14 embryos implanted (63.6% per transferred embryo). Three patients delivered three healthy babies, during writing, the other pregnancies (two twins and seven singletons) are ongoing beyond 20 weeks of gestation. CONCLUSIONS The data obtained demonstrate that array-CGH can detect chromosome imbalances in embryos, also providing the added benefit of simultaneous aneuploidy screening of all 24 chromosomes. Array-CGH has the potential to overcome several inherent limitations of FISH-based tests, providing improvements in terms of test performance, automation, sensitivity and reliability.

Abstract
PURPOSE Cryopreservation of blastocysts, especially those subjected to the trauma due to blastomere biopsy for the purposes of pre-implantation genetic screening (PGS), requires significant optimization. Laboratory and clinical outcomes were compared to determine the effect of two different cryopreservation techniques on the development of human pre-implantation embryos that underwent blastomere biopsy and blastocoel drainage prior to cryopreservation. DESIGN Retrospective clinical study. PATIENT(S) Women who requested cryotransfer of supernumerary blastocysts were analyzed by FISH. RESULTS The main outcome measures were post-thaw survival (SR), pregnancy (PR), and implantation (IR). The SR of slowly frozen blastocysts was 83% compared to 97% for vitrified blastocysts. In 160 cases where biopsied embryos were cryotransferred, the results for slowly frozen versus vitrified blastocysts were: SR (71% vs. 95%), PR (23% vs. 37%), and IR (26% vs. 36%, P < 0.05), respectively. CONCLUSION The results revealed that vitrified blastocysts provided higher SR, PR and IR as compared to slowly frozen counterparts.
