Abstract
Introduction: Robertsonian translocation (RobT) is the central fusion of the long arms of two acrocentric
chromosomes, leading to 45 chromosomes in humans. The most common ones are rob(13;14)
and rob(14;21) (91%). Other types of RobT are so-called rare cases. In the general population
RobTs occur with a frequency of approximately 0.123%, but among men with reproductive
failure this value rises 9-fold. Infertility in RobT carriers is associated with the formation of
unbalanced spermatozoa resulting from segregation of the chromosomes involved in trivalent
during the meiotic prophase. In spermatozoa of many RobT carriers an increased level
of chromosomal aneuploidy is observed.
Materials and Methods: We examined the hyperhaploidy level of chromosomes 7, 9, 18, 21, 22, X and Y in spermatozoa
of 6 RobT unrelated carriers: two carriers with rare rob(13;15), one with rare rob(13;22), and
three of the common rob(13;14). Results were compared with the control data from a group
of 7 fertile men with a normal karyotype. Fluorescent in situ hybridization (FISH) was applied.
Results: We found an increased level of sperm aneuploidy regarding at least one of the analyzed
chromosomes in each of the carriers, while in rare RobTs interchromosomal effect (ICE) was
observed. Meiotic segregation pattern of a rare rob(13;15) carrier revealed the 76% of normal
/balanced spermatozoa.
Disucussion: Due to the relatively high population frequency of RobTs, their influence on reproductive
failure, hight risk of imbalancement in prenatal diagnosis (7%), and small amount of data for
rare RobTs, each newly characterized case is valuable in genetic counseling.

Abstract
In men with oligozoospermia, Robertsonian translocations (RobTs) are the most common type of autosomal aberrations. The most commonly occurring types are rob(13;14) and rob(14;21), and other types of RobTs are described as 'rare' cases. Based on molecular research, all RobTs can be broadly classified into Class 1 and Class 2. Class 1 translocations produce the same breakpoints within their RobT type, but Class 2 translocations are predicted to form during meiosis or mitosis through a variety of mechanisms, resulting in variation in the breakpoint locations. This review seeks to analyse the available data addressing the question of whether the molecular classification of RobTs into Classes 1 and 2 and/or the type of DD/GG/DG symmetry of the involved chromosomes is reflected in the efficiency of spermatogenesis. The lowest frequency value calculated for the rate of alternate segregants was found for rob(13;15) carriers (Class 2, symmetry DD) and the highest for rob(13;21) carriers (Class 2, DG symmetry). The aneuploidy values for the rare RobT (Class 2) and common rob(14;21) (Class 1) groups together exhibited similarities while differing from those for the common rob(13;14) (Class 1) group. Considering the division of RobT carriers into those with normozoospermia and those with oligoasthenozoospermia, it was found that the number of carriers with elevated levels of aneuploidy was unexpectedly quite similar and high (approx. 70%) in the two subgroups. The reason(s) that the same RobT does not always show a similar destructive effect on fertility was also pointed out.

Abstract
PURPOSE To investigate the effects of a carrier's sex and age on the segregation patterns of the trivalent of Robertsonian translocations. METHODS This retrospective study was designed to analyze the segregation patterns of the trivalent and euploidy rates of blastocysts. Data were collected from 154 couples with Robertsonian translocation (77 with a female carrier and 77 with a male carrier). Embryos were diagnosed via array comparative genomic hybridization between January 2013 and July 2017. The segregation patterns of the trivalent of 604 blastocysts were analyzed according to the carrier's sex and age. RESULTS The proportion of alternate segregation was significantly higher (82.9% vs. 55.2%) in the male carriers than in the female carriers of Robertsonian translocation, and the proportion of adjacent segregation was significantly lower (16.8% vs. 42.6%), with no difference in 3:0 segregation. The segregation patterns were similar in same-sex carriers when analyzed according to the type of translocation. The carrier's age had no influence on the segregation patterns of the trivalent. CONCLUSIONS The proportions of the trivalent's meiotic segregation pattern differ significantly according to the carrier's sex in Robertsonian translocations and are independent of the carrier's age. A significantly higher proportion of alternate segregation for normal or balanced chromosome contents was observed in the blastocysts of the male carriers than in those of the female carriers.

Is sperm FISH analysis still useful for Robertsonian translocations? Meiotic analysis for 23 patients and review of the literature. Basic Clin Androl 2018; 28:5. [PMID: 29760927 PMCID: PMC5937048 DOI: 10.1186/s12610-018-0069-z] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2017] [Accepted: 03/08/2018] [Indexed: 01/09/2023] Open
Abstract
Background Robertsonian translocations (RobT) are common structural chromosome rearrangements where carriers display a majority of chromosomally balanced spermatozoa from alternate segregation mode. According to some monotony observed in the rates of balanced segregation, is sperm FISH analysis obsolete for RobT carriers? Methods Retrospective cohort research study on 23 patients analyzed in our center from 2003 to 2017 and compared to the data of 187 patients in literature from 1983 to 2017. Robertsonian translocation carriers were divided in six groups according to the chromosomes involved in the translocation: 9 patients from our center and 107 from literature carrying 45,XY,der(13;14) karyotype, 3 and 35 patients respectively with 45,XY,der(14;21), 5 and 11 patients respectively with 45,XY,der(13;15), 4 and 7 patients respectively with 45,XY,der(14;15), 1 and 4 patients respectively with 45,XY,der(13;22),and 1 and 10 patients respectively with 45,XY,der(14;22). Results Alternate segregation mode is predominant in our group of Robertsonian translocation carriers with 73.45% ±8.05 of balanced spermatozoa (min 50.92%; max 89.99%). These results are compliant with the data from literature for all translocations types (p > 0.05) and are consistent among the different types of Robertsonian translocations (p > 0.05) except for der(13;15) that exhibit lower balanced spermatozoa rates (p < 0.05 versus der(13;14), der(14;21), (13;21) and der(15;22)). Normozoospermic patients also display a significantly (p < 0.01) higher rate of balanced sperm cells than patients with abnormal seminograms whatever the defect implied. Conclusions According to the discrepancies observed between der(13;15) and all the other Rob T carriers, the differences observed among patients presenting normal and abnormal sperm parameters and the input in genetical counselling, sperm FISH does not seem obsolete for these patients. Moreover, it seems important to collect more data for rare RobT.

Abstract
PURPOSE 45,XY,t(13;14)(q10;q10) karyotype can suggest infertility associated with more or less severe oligospermia in male adults. In addition, 45,XX,t(13;14)(q10;q10) karyotype carries reproductive risks such as miscarriage or infertility in female adults. However, reports on the phenotype of this karyotype in children are very rare. This study was done to observe various phenotypes of this karyotype in children. METHODS Between January 2007 and December 2012, children diagnosed with 45,XY,t(13;14)(q10;q10) or 45,XX,t(13;14)(q10;q10) karyotype by chromosome analysis were analyzed retrospectively. RESULTS Eight children (5 boys and 3 girls) were diagnosed with 45,XY,t(13;14)(q10;q10) or 45,XX,t(13;14)(q10;q10) karyotype. They ranged in age from 5 years and 6 months to 12 years and 4 months. The phenotypes of the study patients consisted of 1 hypogonadotrophic hypogonadism, 1 precocious puberty, 3 early puberty, 2 growth hormone deficiency (GHD) (partial) and 1 idiopathic short stature. As shown here t(13;14)(q10;q10) Robertsonian translocation shows a wide range of phenotypes. CONCLUSION It can be said that t(13;14)(q10;q10) Robertsonian translocation shows various phenotypes from GHD to precocious puberty in children. Further large-scale studies are necessary.

Abstract
PURPOSE To study meiotic segregation patterns of Robertsonian translocations in sperm of male carriers and to assess the frequencies of unbalanced sperm formation. METHODS FISH with combination of probes to detect all the variants of meiotic segregation was performed on decondensed sperm nuclei of 5 carriers of der(13;14), 3 carriers of der(14;21) and one carrier of a rare der(13;21) translocation. RESULTS The frequency of sperm with alternate segregation and normal/balanced chromosomal complement ranged from 68 % to 94.4 % (mean 79.2 ± 8.4). Adjacent segregation was detected in 17.9 ± 7.3 % of sperm (from 5.6 % to 29 %). No significant differences in frequencies of gametes with nullisomies and disomies of chromosomes involved in translocations were observed. The mean frequency of 3:0 segregation products was 2.5 ± 1.4 %. CONCLUSIONS All analyzed patients showed homogenous segregation pattern with clear predominance of alternate segregation resulting in normal/balanced sperm production. Still, from 5.8-32 % (mean 20.4 ± 8.3 %) of sperm was unbalanced, which is the evidence of the increased risk of unbalanced offspring in carriers of Robertsonian translocations. Our results highlight the importance of genetic counseling of Robertsonian translocation carriers prior to ICSI or IVF.

Abstract
PURPOSE To analyse the segregation of a Robertsonian translocation t(13;14) in five male carriers, and to verify a possible inter-chromosomal effect (ICE) of the Robertsonian translocation on chromosomes 18, X, and Y. METHODS The spermatozoa of these patients (n = 5) and of 15 donors with normal semen parameters and 46,XY karyotype were analysed using triple colour FISH with locus specific probes for chromosomes 13, 14, and 21 and by triple colour FISH for chromosomes X, Y, and 18. RESULTS The frequency of balanced spermatozoa resulting from alternate segregation varied between 62.16% and 81.70% with a mean of 71.5%. The rates of unbalanced spermatozoa resulting from adjacent segregation varied between 13.4% and 25.1% with a mean of 18.26%. Triple colour FISH X-Y-18 showed a significant increase in disomy frequencies of these chromosomes in comparison with controls, indicating an ICE. CONCLUSION In spite of the high number of normal/balanced frequencies, there remain many unbalanced spermatozoa resulting from adjacent mode of segregation. This raises the question of the unbalanced chromosomal risk for the offspring of 45,XY, t(13;14) males and the importance of the genetic counselling prior to ICSI or IVF treatment for couples where the male is a Robertsonian translocation carrier.

Abstract
BACKGROUND Infertility is a natural mechanism of selection intended to prevent the delivery of a child with malformations or mental retardation. Male infertility is closely related to chromosomal abnormalities. This study was focused on the analysis of meiotic segregation involving a Robertsonian translocation, 45,XY,der(13;13) [56]/45,XY,der(13;14) [44] and the evaluation of possible interchromosomal effects. RESULTS Hybridisation with LSI 13q14 and subtelomere 14q probes and WCP13 SpectrumGreen and WCP14 SpectrumOrange probes showed a high proportion of unbalanced gametes, corresponding to 71.2% of the spermatozoa. The disomic frequencies of the sexual chromosomes and chromosome 18 of the patient were higher (5.28% and 2.55%, respectively) than those of the control (0.6% and 0.59%, respectively). CONCLUSION Meiotic segregation studies in sperm are an important tool for genetic counselling of chromosomal aberrations, allowing for a prediction of the risks and consequent implications for the reproductive life. The patient with this rare translocation exhibited meiotic segregation fidelity, and a high rate of unbalanced gametes with disomic spermatozoa.

Abstract
PURPOSE To provide more genetic information about meiotic segregation behavior and the possibility of interchromosomal effects (ICE) in spermatozoa from carriers of Robertsonian (Rob) translocations. MATERIALS AND METHODS Meiotic segregation behavior in spermatozoa from six carriers of Rob translocations, four t(13;14), one t(14;22) and one t(13;21), was investigated by dual fluorescence in-situ hybridization (FISH). Aneuploidy for chromosomes 18, X and Y was studied by triple FISH. RESULTS The rate of normal/balanced spermatozoa resulting from alternate segregation ranged from 78.14 to 86.88%. The frequency of unbalanced spermatozoa resulting from adjacent segregation varied between 11.70 and 19.53%. The higher frequencies of aneuploidy for sex chromosome were observed in three Rob translocation carriers. In addition, the increased rates of diploid were found in two t(13;14) carriers. CONCLUSIONS Alternate segregation is dominant in the different types of Rob translocations. Some carriers may be at an increased risk for ICE.

Abstract
Male carriers of Robertsonian (Rob) translocations can have fertility problems associated with low sperm counts and abnormal sperm morphology. In this study, spermatozoa from 14 Rob translocation carriers, seven der(13;14), two der(13;15), two der(14;15), two der(14;21) and one der(21;22), were tested by fluorescence in-situ hybridization (FISH) for the chromosomes involved, to study meiotic segregation behaviour. It was shown that in each type of Rob translocation, meiotic segregation behaviour is similar, comparable and occurs non-randomly. Most of the spermatozoa results from alternate segregation (range: 76-89.47%). There is, however, still much unbalanced spermatozoa resulting from adjacent segregation mode (range: 10.24-23.41%). These data provide useful information for genetic counselling purposes. Moreover, aneuploidy for chromosomes 13,18, 21, X and Y was studied in five patients and suggested an inter-chromosomal effect.

Abstract
In 1964, Gustavsson and Rockborn first described the 1/29 Robertsonian translocation in cattle. Since then, several studies have demonstrated the negative effect of this particular chromosomal rearrangement on the fertility of carrier animals. During the last decade, meiotic segregation patterns have been studied on human males carrying balanced translocations using FISH on decondensed sperm nuclei. In this work, we have applied the 'Sperm-FISH' technique to determine the chromosomal content of spermatozoa from two bulls heterozygous for the 1/29 translocation and one normal bull (control). 5425 and 2702 sperm nuclei were scored, respectively, for the two heterozygous bulls, using whole chromosome painting probes of chromosomes 1 and 29. Very similar proportions of normal (or balanced) spermatozoa resulting from alternate segregation were observed (97.42% and 96.78%). For both heterozygous bulls, the proportions of nullisomic and disomic spermatozoa did not follow the theoretical 1:1 ratio. Indeed, proportions of nullisomic spermatozoa were higher than those of disomic sperma tozoa (1.40% vs 0.09% (bull 1) and 1.29% vs 0.15% (bull 2) for BTA1, and 0.65% vs 0.40% (bull 1) and 1.11% vs 0.63% (bull 2) for BTA29). The average frequencies of disomic and diploid spermatozoa in the normal bull were 0.11% and 0.05%, respectively.

Abstract
Many surveys have been performed to find etiological relationships between pregnancy outcome and specific risk factors, such as exposure to chemicals and radiation or parental age. Advanced maternal age is a strong risk factor for trisomic pregnancies, albeit there are considerable variations among the different chromosomes. The definite incidence of the various structural and numerical chromosome aberrations in spontaneous abortions and liveborns is well known, as well as the rate of maternally and paternally derived rearrangements. Nevertheless studies have failed to assert an age-dependent risk for men fathering chromosomally abnormal children. New techniques using fluorescence in situ hybridization render it possible to analyze spermatozoa directly for numerical and, to some extent, for structural aberrations. This article compiles the findings of studies on human spermatozoa over the last few years.

Abstract
Robertsonian translocations are the most frequent structural chromosomal abnormalities in humans and can affect fertility, with various degrees of sperm alterations in men; or the pregnancy outcome of the carriers. The studies on meiotic segregation of chromosomes in sperm of Robertsonian translocation males find a majority of normal or balanced spermatozoa for the chromosomes related to the translocation (mean 85.42%; range 60-96.60%). Furthermore, recent studies suggest an interchromosomal effect. Studies on spermatozoa from translocation carriers, and in mouse models help the comprehension of the meiotic segregation mechanisms. Results of meiotic segregation analysis in man could be integrated in genetic counselling especially when assisted reproductive technology is required.

Abstract
Meiotic segregation of a Robertsonian translocation (13;15) was assessed in sperm nuclei using dual-color fluorescent in situ hybridization (FISH) with whole-chromosome paint probes. Most spermatozoa in the (13;15) translocation carrier resulted from alternate segregation. Although an increased frequency of unbalanced gametes was observed, spontaneous pregnancy led to the birth of a boy with a normal karyotype.

Abstract
BACKGROUND The t(13;22) Robertsonian translocation constitutes a rare form of rearrangement between acrocentric human chromosomes. Most of the meiotic segregation studies of human Robertsonian translocations have been performed on common t(13;14) and t(14;21) translocations. Analysis of the chromosomal constitution in sperm of Robertsonian translocation carriers is of great interest for assessing the risk of unbalanced forms and adapting genetic counselling. In the present study, we present the first meiotic segregation study of a t(13;22) Robertsonian translocation in human sperm. METHODS A total of 11 787 sperm nuclei were scored using two distinct FISH labelling techniques, i.e. the locus-specific probes (LSI) method and the whole chromosome painting (WCP) technique. RESULTS The frequency of normal or balanced sperm resulting from alternate meiotic segregation was 86%. Incidences of unbalanced complements resulting from adjacent segregation modes were 12.79% and 14.36% in LSI and WCP assays, respectively. No significant excess of nullisomy or disomy for the affected chromosomes was observed. CONCLUSIONS Similar results in segregation were obtained with the two techniques, demonstrating the efficiency of the two strategies for the direct segregation analysis of Roberstsonian translocations. The results obtained indicated a moderate meiotic production of imbalance. This study shows that the rare Robertsonian translocation (13;22) displays a similar distribution of balanced and unbalanced sperm patterns as the common Robertsonian translocations previously studied. This suggests that the behaviour of acrocentric chromosomes was similar in all cases of centric fusion.

Abstract
Balanced reciprocal and Robertsonian translocations are the most common structural chromosomal abnormalities in humans. Generally, they are without consequence for the carrier, but for various degrees of oligoasthenoteratozoospermia in men. As these carriers can produce a significant percentage of gametes with an unbalanced combination of the parental rearrangement, there is a more or less significant risk, according to cases, of chromosomal imbalances for their offspring. Therefore, techniques were developed to study the meiotic segregation of these translocations in males. Direct investigation of human sperm chromosomes became possible by karyotyping spermatozoa after penetration of zona-free hamster oocytes and, more recently, using fluorescent in situ hybridization (FISH). This paper reviews the results obtained using these techniques in Robertsonian and reciprocal translocations. The studies on spermatozoa from translocation carriers help the comprehension of the mechanisms of the meiotic segregation. They should be integrated in the genetic exploration of the infertile men, in order to give them a personalized risk assessment of unbalanced spermatozoa, specially as a correlation was found recently between the percentage of abnormal spermatozoa and that of abnormal embryos.

Abstract
Haploid chromosomes of a total of 354 spermatozoa from two bulls heterozygous for different Robertsonian translocations, a Holstein-Friesian bull carrying a t(1;21) and a Japanese Black bull carrying a t(7;21), were analyzed using an interspecific in vitro fertilization system with zona-free hamster oocytes. The proportion of chromosomally normal and balanced spermatozoa was approximately equal in both carriers (51.8% and 47.0% in the 1/21 carrier, and 47.3% and 50.0% in the 7/21 carrier). The combined incidences of normal and balanced spermatozoa, i.e., incidences of spermatozoa resulting from alternate meiotic segregation were very high (98.8% and 97.3%) in both carrier. On the contrary, the incidences of chromosomally unbalanced spermatozoa resulting from adjacent meiotic segregation were only 0.6% and 2.7%. These results indicate that the alternate segregation of a trivalent chromosome is predominant in these Robertsonian translocation carriers.

Abstract
Meiotic segregation patterns of carriers of Robertsonian translocations (RT) are important for assessing the risk of unbalanced forms. We investigated the ratio of sperm with t(21;21) to sperm with nullisomy for chromosome 21; the segregation of the t(21;21) along with sex chromosomes, and also interchromosomal effects on chromosome 10 by using three color fluorescence in situ hybridization (FISH) with telomere specific (Tel 21q) and centromere-specific alpha satellite probes for chromosomes X, Y, and 10. The percentage of cosegregation of t(21;21) with sex chromosomes (49.50%) and without sex chromosomes (46.98%) was not significant. There are no significant differences between the percentages of cosegregation of t(21;21) with chromosome X (23.36%) and with chromosome Y (26.16%). No evidence of an interchromosomal effect on chromosome 10 was detected, the percentage of chromosome 10 aneuploidy being similar to that in controls. In addition, the frequency of diploid sperm nuclei was not significantly higher in the carrier (0.32%) than in the controls (0.44%) (P > 0.05). The sex ratio was similar within the carrier and the controls and between the carrier and the control. Three color-FISH analysis, using different probe combinations, seems a rapid and accurate tool for direct analysis of meiotic segregation product.

Abstract
Advances in molecular cytogenetics, especially the technique of fluorescence in situ hybridization (FISH), have allowed more precise definition of chromosomal structures, which are difficult to identify using conventional G-banding. Recently, a novel approach based on hybridization of 24 fluorescent-labelled chromosome painting probes was developed, termed spectral karyotyping (SKY), which allows the simultaneous and differential colour display of all human chromosomes. We have used SKY to identify not only five parental complex translocation carriers but also minute chromosome rearrangements in the fetus. Here, we concentrate attention on the clinical application of SKY for prenatal diagnosis.

Abstract
Meiotic segregation of chromosomes 13 and 14 was studied in the ejaculated spermatozoa of three men carrying a translocation der(13;14)(q10;q10). The spermatozoa of these patients and of a donor with a normal 46,XY karyotype (control) were analysed by two-colour fluorescent in-situ hybridization (FISH) with specific chromosomal painting of chromosomes 13 and 14, by two-colour FISH detecting chromosomes 18 and 21 and by triple-colour FISH for chromosomes X, Y and 8. For patients 1, 2 and 3, respectively, 81.34, 82.60 and 88.90% of the analysed nuclei showed normal or balanced chromosomal status, resulting from the alternate segregation of the translocation. The rates of spermatozoa with an unbalanced status (disomy and nullisomy, 13 or 14) resulting from the adjacent mode of segregation were estimated respectively at 18.06, 16.32 and 10.80 (for patients 1, 2 and 3). Additional colour FISH analysis with probes specific for chromosomes X, Y, 8, 18 and 21 showed a significant increase in some disomy frequencies (8, 18, 21, X and Y for patient 1, only 18 for patient 2) in comparison with the control. These results would seem to indicate an interchromosomal effect.

Abstract
Transmitted de novo structural chromosomal abnormalities, the majority of which are paternally derived, can lead to abnormal reproductive outcomes as well as genetic diseases in offspring. We developed and validated a new multicolor FISH procedure (sperm ACM, which utilizes DNA probes specific for the alpha [1cen], classical, [1q12], and midi [1p36.3] satellites of chromosome 1) which utilizes DNA probes specific for three regions of chromosome 1 to detect human sperm that carry numerical abnormalities plus two categories of structural aberrations: (1) duplications and deletions of 1pter and 1cen, and (2) chromosomal breaks within the 1cen-1q12 region. In healthy men, the average frequencies of sperm with duplications and deletions were (a) 4.5 +/- 0.5 and 4.1 +/- 1.3 per 10(4) involving 1pter and (b) 0.9 +/- 0.4 and 0.8 +/- 0.3 per 10(4) involving 1cen, respectively. The frequency of sperm exhibiting breaks within the 1cen-1q12 region was 14.1 +/- 1.2 per 10(4). Structural aberrations accounted for 71% of the abnormalities detected by sperm ACM, which was significantly higher than numerical abnormalities (P=2x10-8). Our findings also suggest that, for healthy men, (a) sperm carrying postmeiotic chromosomal breaks appear to be more prevalent than those carrying products of premeiotic or meiotic breakage or rearrangements, (b) the high frequency of chromosome breaks measured after "fertilization" by the hamster-egg cytogenetic method already appear to be present and detectable within human sperm by FISH, and (c) there are nonrandom and donor-specific distributions of breakpoint locations within 1q12 in sperm. FISH facilitates the analysis of much larger numbers of sperm than was possible when the hamster-egg method was used. Therefore, FISH-based procedures for simultaneously detecting chromosomal breaks, rearrangements, and numerical abnormalities in sperm may have widespread applications in human genetics, genetic toxicology, and reproductive medicine.

Abstract
OBJECTIVE To review 35 cases of preimplantation genetic diagnosis (PGD) of translocations with several methods, including telomeric probes. DESIGN Retrospective study. SETTING Clinical IVF laboratory. PATIENT(S) Thirty-five couples with one partner carrying a chromosomal translocation. INTERVENTION(S) PGD of translocation after polar-body or embryo biopsy. MAIN OUTCOME MEASURE(S) Pregnancy outcome. RESULT(S) Several trends were observed. First, PGD can achieve a statistically significant reduction in spontaneous abortion, from 95% to 13%. Second, the chances of achieving pregnancy are correlated with 50% or more of the embryos being chromosomally normal. Third, patients with robertsonian translocations produced fewer abnormal gametes and more pregnancies than did patients with reciprocal translocations. Fourth, a new fluorescence in situ hybridization protocol for PGD of translocations, which involves applying telomeric probes, has proved adequately reliable with a 6% average error rate. CONCLUSION(S) PGD of translocations achieves a statistically significant reduction in spontaneous abortion, both for polar-body and blastomere biopsy cases. Pregnancy outcome depended on the number of normal embryos available for transfer, with patients having <50% abnormal embryos achieving the most pregnancies. Because robertsonian translocations caused fewer abnormal embryos than reciprocal translocations, they also resulted in higher rates of implantation.

Abstract
OBJECTIVE To develop an approach to preimplantation diagnosis of translocations that would not require the use of specific DNA probes for each translocation type. DESIGN Retrospective analysis. SETTING Clinic. PATIENT(S) Two patients with 45XX,der(13;14)(q10;q10) karyotypes and one patient with a 46XX,t(4;14)(p15;q24) karyotype. INTERVENTION(S) Based on the observation that first polar body chromosomes remain at the metaphase stage for a few hours after oocyte retrieval, fluorescence in situ hybridization with chromosome-painting probes was used to perform preconception genetic diagnosis of translocation of maternal origin. MAIN OUTCOME MEASURE(S) Oocyte FISH analysis. RESULT(S) A total of 31 mature oocytes were produced, and results were obtained in 23 first polar bodies. After IVF-ET, all three patients became pregnant, preconception diagnoses being confirmed by prenatal diagnosis or birth. CONCLUSION(S) Preconception diagnosis of translocations may reduce significantly the risk of chromosomally unbalanced offspring and pregnancy loss. This method is simpler than previous approaches because the need to develop specific DNA probes for each translocation type is avoided.

The meiotic segregation of chromosomes 14 and 21 was analysed in 1116 spermatozoa from an oligoasthenospermic carrier of a Robertsonian translocation t(14q21q), and in 16,392 spermatozoa from a control donor, using two-colour fluorescence in situ hybridisation (FISH). Two YAC probes (cloned in yeast artificial chromosomes) specific for regions on the long arms of these chromosomes were co-hybridised. Of the spermatozoa, 12% were unbalanced, resulting from adjacent segregations. Chromosomes X, Y and 1 were also simultaneously detected in 1335 spermatozoa from the same carrier. Whereas gonosomal disomy rates were not significantly different from those of the control donors, disomy 1 were slightly but significantly increased to 0.7%. The diploidy rate was also slightly increased to approximately 1% in the translocation carrier.

Abstract
Sperm chromosome complements from two males, one heterozygous for the reciprocal translocation t(2;17)(q35;p13) (n = 18) and one for t(3;8) (p13;p21) (n = 73), were analyzed. Only 2:2 segregations were observed with t(2;17): alternate, 56%; adjacent-I, 33%; adjacent-II, 11%. Both 2:2 and 3:1 meiotic segregations occurred in t(3;8): alternate, 34.2%; adjacent-I, 43.8%; adjacent-II, 20.5% and 3:1, 1.4%. A significant excess of chromosomally normal versus balanced sperm complements was observed with both translocation heterozygotes. The frequencies of other chromosome aberrations unrelated to the translocations were 16.7% for t(2;17) and 8.2% for t(3;8). The ratio of X-bearing to Y-bearing sperm was not different from the theoretically expected ratio of 1:1.

Abstract
Chromosome complements were studied in 118 sperm from a man heterozygous for a 15;22 Robertsonian translocation using the human sperm/hamster oocyte fusion technique. Alternate segregation occurred in most spreads (89.6%) and the proportion of normal (42.6%) and balanced complements (47%) was approximately equal. The frequency of sperm that were unbalanced with respect to the translocation was 10.4% and all categories of unbalanced sperm were observed (-15, -22, +15, +22). The frequency of chromosome abnormalities unrelated to the translocation was 7.6%. Since the frequencies of both numerical (3.4%) and structural abnormalities (3.4%) were within the normal range of control donors, there was no evidence for an interchromosomal effect. The frequencies of X-chromosome bearing (48%) and Y-chromosome bearing (52%) sperm were not significantly different from 50%. Data on this translocation were compared to the 4 other reports of cytogenetic analysis in sperm of Robertsonian translocation carriers.

Abstract
The frequency and distribution of aneuploidy was compared in 11,615 karyotyped human sperm and 772 karyotyped human oocytes to determine if all chromosomes are equally likely to be involved in aneuploid events or if some chromosomes are particularly susceptible to nondisjunction. The frequency of hypohaploidy and hyperhaploidy was compared among different chromosome groups and individual chromosomes for human sperm and oocytes. In general, hypohaploid chromosome complements were more frequent than hyperhaploid complements, in sperm and oocytes. The distribution of chromosome loss in the hypohaploid complements indicated that significantly fewer of the large chromosomes and significantly more of the small chromosomes were lost, suggesting that technical loss predominantly affects small chromosomes. A conservative estimate of aneuploidy (2 X hyperhaploidy) was approximately 3-4% in the human sperm and 18-19% in human oocytes. All chromosome groups were represented among hyperhaploid human sperm and oocytes. For human sperm, the observed frequency of hyperhaploidy equaled the expected frequency based on the assumption that the frequency of nondisjunction is equal for all chromosome groups, with two exceptions: group G and the sex chromosomes. Among individual chromosomes in human sperm, chromosomes 1 and 21 and the sex chromosomes had a significant excess of hyperhaploidy. For human oocytes, there were fewer hyperhaploid oocytes than expected for chromosome groups C and F and more than expected for chromosome groups D and G. Among individual chromosomes there was a significant excess for chromosome 21. These results indicate that all chromosomes are susceptible to nondisjunction but that chromosome 21 is particularly prone to aneuploidy in both human sperm and oocytes. They also demonstrate that sex chromosome aneuploidy is common in human sperm but not in human oocytes.

Abstract
Cytogenetic analysis of 121 sperm from a man heterozygous for a t(13;14) Robertsonian translocation was performed using the technique of in vitro penetration of hamster eggs. The frequency of sperm that were chromosomally unbalanced with respect to the translocation was 27%. The frequency of chromosomally normal (36%) and balanced (38%) complements was approximately equal, as theoretically expected. There was no evidence for an interchromosomal effect since the frequency of numerical chromosomal abnormalities (2.5%) and structural chromosomal abnormalities (10.7%)--both unrelated to the translocation--were within the normal range of control donors. The ratio of X- and Y-chromosome bearing sperm was equal, and there was no evidence for preferential segregation of the X chromosome with the translocation.
