Abstract
To modify a fixation method improving the intensity and clarity of the single blastomeric signal detection by fluorescence in situ hybridization (FISH) in preimplantation genetic diagnosis. 333 cycles of assisted reproduction with preimplantation genetic diagnosis FISH (PGD-FISH) performed in our hospital were analyzed and a total of 3452 single blastomeres were obtained. For the conventional fixation method, the blastomeres were kept in 0.1% sodium citrate with 0.2 mg/ml bovine serum albumin (BSA) for 2-5 min. FISH was performed and the internal relationship between embryo quality and fixed rate, signal detection rate, and signal determination rate was explored. With the modified method, 91.54% of blastomeres were fixed, while 88.30% were fixed with the conventional method. The signal detection rate was significantly increased for the modified group than for the conventional group (compared 98.53% with 94.78%, P < 0.001). Especially, the signal determination rate also showed a significant difference between the two methods (compared 90.51% with 74.17%, P < 0.001). After the development of the fixation method, the fixation efficiency and the signal determination rate were greatly improved, providing more definite diagnosis for the patient. It will hopefully allow more assisted reproduction programs to offer their patients preimplantation genetic diagnosis with FISH.

Abstract
OBJECTIVE To investigate the evolution of techniques and strategies and to evaluate the results of preimplantation genetic diagnosis (PGD) from January 2000 to December 2004 in chromosomal, monogenic and mitochondrial DNA disorders treated at our institution. DESIGN Retrospective study. SETTING Single French Parisian PGD center. PATIENT(S) Patients at risk of transmitting a serious genetic disorder to their offspring. INTERVENTION(S) 171 couples enrolled in the program undergoing stimulated and frozen embryo replacement cycles with PGD. MAIN OUTCOME MEASURE(S) Results of the 441 first PGD cycles performed for various genetic conditions. RESULT(S) During 5 years, 416 stimulation and 25 frozen embryo replacement cycles were started, among which 52 clinical and 47 ongoing pregnancies occurred. In stimulation cycles, the overall ongoing pregnancy rate was 24% per embryo transfer, 11% per started cycle, and 27% per couple. The implantation rate was 16%. CONCLUSION(S) These encouraging results demonstrate that PGD might be considered as a valid alternative to prenatal diagnosis. Nevertheless, couples referred for PGD must be selected and counseled appropriately, considering the complexity of the treatment and the relatively low take-home baby rate.

Abstract
OBJECTIVE To report the results of preimplantation genetic diagnosis (PGD) cycles performed in our unit from 2000 to 2004. Materials and methods. One hundred and seventy-one couples were enrolled in the PGD program over this period. The collected oocytes were inseminated by intracytoplasmic sperm injection (ICSI). The resulting embryos were biopsied on the third day of development and the genetic analysis was performed on the same day. Embryo transfers were carried out on the fourth day. RESULTS The 416 stimulation cycles started yielded 280 oocyte pick-ups, 3506 oocytes retrieved, of which 2966 were suitable for ICSI. Among the 1982 embryos obtained, 1337 embryos were biopsied and genetic diagnosis was performed for 1083 (81%) of them. 381 embryos were transferred during the course of 189 transfer procedures. There were 51 clinical and 46 ongoing (35 single, 11 twin) pregnancies. In addition, 25 frozen embryo replacement cycles were initiated, leading to 6 embryo transfers and 1 ongoing pregnancy. A total of 58 unaffected children were born. CONCLUSION PGD has gained a place among the choices offered to couples at risk of transmission of a serious and incurable genetic disease. It might be a realistic alternative to prenatal diagnosis for patients carrier of chromosomal rearrangements, single gene defects, X-linked disesases or mitochondrial DNA disorders.

Abstract
BACKGROUND Myotonic dystrophy (MD) is characterized by myotonia, multisystemic lesions and hypogonadism. In women, the relationship between MD and infertility remains controversial. This study investigated the ovarian status and response to controlled ovarian stimulation (COS) in MD women entering our preimplantation genetic diagnosis programme. METHODS We elected to compare MD patients with X-linked disorders (XLD) carriers, given that XLD have not been shown to affect ovarian status. On the one hand, we analysed all the cycles performed and, on the other hand, we conducted a subanalysis based on only first cycles. RESULTS MD and XLD groups were similar with regard to women's ages, day 3 parameters, number of oocytes retrieved, embryos obtained and prevalence of top quality embryos. The day of HCG was significantly delayed and the prevalence of poor quality embryos was higher in the MD group. The subanalysis on first cycles only also showed significantly fewer mature follicles on the day of HCG in MD population. Implantation and pregnancy rates were similar in both groups; however, no pregnancy occurred at the first cycle in MD (0 out of 4), whereas 77% of pregnancies (10/13) occurred at the first attempt in XLD carriers. CONCLUSIONS These results indicate that the responsiveness to COS was moderately hindered in MD women as compared to controls. Reassuring data about implantation and pregnancy rates support the feasibility of PGD in selected mildly affected MD women.

Abstract
OBJECTIVE To evaluate the potential of proliferation of single blastomeres isolated from human cleavage-stage embryos for use in preimplantation genetic diagnosis of chromosomal abnormalities. DESIGN A laboratory study of chromosomal content of blastomeres isolated from embryos of patients from an in vitro fertilization program. SETTING University hospital laboratory. PATIENT(S) Couples undergoing IVF or ICSI. INTERVENTION(S) Blastomeres were isolated from normally fertilized cleavage-stage human embryos, cultured in vitro or fixed immediately, and analyzed by fluorescence in situ hybridization (FISH) probes. MAIN OUTCOME MEASURES Chromosomal information yielded by blastomeres cultured in vitro compared with those obtained from blastomeres that were processed for chromosomal analysis directly after isolation. RESULT(S) The percentage of cultured blastomeres that produced FISH results was significantly lower than the percentage of blastomeres processed for FISH directly after isolation (72% vs. 90%). Lack of FISH results from cultured cells, which in most cases was related to nuclear anomalies, was significantly more frequent among nondivided than divided blastomeres (39% vs. 21%). Both cultured and noncultured cells showed diploid, aneuploid and polyploid chromosome complements on FISH. Compared with directly processed cells, cultured cells yielded a higher proportion of polyploid patterns (22.9% vs. 6.1%). Of the cultured blastomeres that divided, 18% produced progeny with mosaicism. CONCLUSION(S) Although blastomere culture may increase the number of cells available for chromosomal analysis, the high frequency of nuclear defects and the occurrence of polyploidy and mosaicism among cultured cells discourage the use of blastomere isolation and proliferation strategy for use in preimplantation genetic diagnosis.

Abstract
One of the most critical steps in preimplantation genetic diagnosis (PGD) studies is the fixation required to obtain good fluorescence in-situ hybridization (FISH) nuclear quality without losing any of the cells analysed. Different fixation techniques have been described. The aim of this study was to compare three fixation methods (1, acetic acid/methanol; 2, Tween 20; 3, Tween 20 and acetic acid/methanol) based on number of cells lost after fixation, average rate of informative cells, rate of signal overlaps and FISH errors. A total of 100, 106 and 114 blastomeres were fixed using techniques 1, 2 and 3 respectively. Technique 2 gave the poorest nuclear quality with higher cytoplasm, number of overlaps and FISH errors. Although technique 1 showed better nuclear quality in terms of greater nuclear diameter, fewer overlaps and FISH errors, it is difficult to perform correctly. However, technique 3 shows reasonably good nuclear quality and is both easier to learn and use for PGD studies than the others.

Abstract
PURPOSE We compared three different probe combinations for detection of postzygotic mosaic imbalances in human preimplantation embryos. METHODS Two hundred and two spare cleavage stage embryos were hybridized with fluorescently labelled DNA probe mixtures specific to chromosomes X, Y, 18 (N = 67), chromosomes 2, 7, 18 (N = 71), or chromosomes 13, 16, 18, 21, 22 (N = 64). RESULTS An overall higher incidence of abnormalities was detected using probe mixture for five (69%) or three (72%) autosomes compared to one autosome and chromosomes X and Y (54%). The rate of aneuploidy detected increased with the number of autosomes hybridized from 4% (X, Y, 18) to 11% (2, 7, 18) to 19% (13, 16, 18, 21, 22). Postzygotic mosaicism comprised the most frequent abnormality detected by all probe combinations, and the percentage detected by each was similar, 48% (X, Y, 18), 56% (2, 7,18), and 50% (13,16,18, 21, 22). CONCLUSIONS A probe combination of five autosomes, particularly those of clinical relevance, may be more beneficial for screening embryos from patients at risk of maternal-age-related aneuploidy. However, all three probe combinations are as efficient at identifying postzygotic mosaicism, and may be used for identifying embryos with less potential of developing to term.

Abstract
Preimplantation genetic diagnosis (PGD) was performed in two couples to avoid chromosomally unbalanced progeny in a family in which a brother and a sister carry an identical maternally inherited balanced translocation t(3;11)(q27.3;q24.3). Embryos were biopsied 3 days after fertilization and blastomeres were analysed by fluorescent in-situ hybridization (FISH). Embryos were classified as unbalanced or normal/balanced. In the first case, the male carrier and his wife underwent one IVF/PGD treatment cycle. In all, 18 embryos were analysed. Of those, 15 revealed an unbalanced karyotype. For one embryo, results were not conclusive, from one embryo results were contradictory and one embryo was classified as normal/balanced and subsequently transferred. A singleton pregnancy was achieved. The PGD analysis was confirmed at 16 weeks gestation by amniocentesis. At term, a healthy girl with a balanced karyotype was born. Pregnancy and delivery were without complications. In the second case, the female carrier and her husband underwent two IVF/PGD treatment cycles. During the first cycle, three embryos were analysed. One embryo revealed an unbalanced karyotype and two embryos were designated a normal/balanced karyotype and transferred but no pregnancy was achieved. During the second PGD cycle three embryos were analysed. Of those, none appeared suitable for transfer. The couple decided not to undergo further treatment. Our results indicate that for individuals carrying a reciprocal translocation PGD is a feasible approach to obtain embryos with a normal chromosome balance and to avoid both spontaneous and induced abortion.
