Rescue ICSI of unfertilized oocytes after IVF.
BACKGROUND Failed fertilization after IVF occurs in 10-20% of cycles. Conflicting results of rescue fertilization by ICSI have been reported. We therefore compared the success rate in terms of fertilization and pregnancy of cycles in which rescue ICSI was performed with those from a matched control group of primarily ICSI cycles. METHODS Unfertilized oocytes from IVF cycles with total fertili...
متن کاملPerinatal risks after IVF and ICSI.
Pregnancies that occur after infertility treatment, particularly after assisted reproduction, constitute high-risk pregnancies. Occurrences of conditions such as high blood pressure, preeclampsia, growth retardations and bleeding are higher in comparison with the norm of spontaneously entered pregnancies. The rate of premature births and the frequency of intrauterine deaths are much higher than...
متن کاملGrowth rate of human preimplantation embryos is sex dependent after ICSI but not after IVF.
BACKGROUND There is concern that IVF and/or ICSI might have an adverse effect on embryonic development via epigenetic alterations. Such alterations might also be involved in the sex-related growth differences in preimplantation embryos found in some animal species. In the present study we analysed cell numbers of human male and female surplus embryos that developed to the blastocyst stage after...
متن کاملBiological Dose Assessment by Chemical Induction of Premature Chromosome Condensation
Dose assessment of radiation victims is a key element in medical management of radiation accidents. At high radiation doses (> 6 Gy), dicentric assay lose its efficiency and premature chromosome condensation (PCC) assay was proposed to overcome the restrictions of dicentric assay. It was shown that PCC ring is more suitable and simpler than dicentric for biodosimetry in high radiation doses. In...
متن کاملAnalysis of interphase chromosome damage by means of premature chromosome condensation after X- and ultraviolet-irradiation.
Sendai virus-mediated fusion between mitotic and interphase mammalian cells causes the rapid condensation of the interphase chromosomes into distinct structures, a process termed premature chromosome condensation. This phenomenon has been used to assess the immediate action of x-rays and ultraviolet light on the chromosomes of HeLa cells irradiated in the G1 phase of the life cycle. X-irradiati...
