Prenatal testing in ICSI pregnancies: incidence of chromosomal anomalies in 1586 karyotypes and relation to sperm parameters.
BACKGROUND Prenatal testing was offered in all pregnancies obtained after ICSI with ejaculated or non-ejaculated sperm as part of the evaluation of the safety of ICSI. METHODS Between 1990 and 2001, a chorionic villus sampling (CVS) or amniocentesis was offered for multiple or singleton pregnancies respectively during a genetic counselling session for all couples applying for ICSI. ICSI was c...

15 صفحه اولEffect of Protamine Deficiency on Fertilization Outcome and Incidence of Sperm Premature Chromosomal Condensation Post ICSI
Purpose: After aneuploidy,sperm premature chromatin condensation (PCC) is the next most important cause of fertilization failure. Therefore the aim of this study is to evaluate the effect of sperm protamine deficiency on sperm PCC formation post ICSI. Materials and Methods: Cytogenetic analysis was carried out on unfertilized oocytes post ICSI and incidence of sperm PCC was evaluated. The resu...
متن کاملIncidence of sperm chromosomal abnormalities in a risk population: relationship with sperm quality and ICSI outcome.
BACKGROUND An increased incidence of chromosome abnormalities has been reported in sperm samples of many infertile men by fluorescence in-situ hybridization (FISH). METHODS Sperm aneuploidy and diploidy rates for chromosomes 13, 18, 21, X and Y were evaluated in 63 patients with normal karyotypes using dual and triple-colour FISH techniques. Indications for sperm FISH analysis were: recurrent...
متن کاملThe incidence of preeclampsia in ICSI pregnancies
OBJECTIVE We aimed to evaluate the association between infertility etiology in ICSI pregnancies and preeclampsia; besides, we aimed to discuss the effect of the paternal factor in the pathogenesis of preeclampsia. HYPOTHESIS We hypothesized that preeclampsia is more common in ICSI pregnancies with male factor. It is known that maternal exposure to paternal sperm cells over a time period has a...
