Transgenic animals play a vital role in basic research, agriculture and pharmaceutical industries. Rabbits have the advantage of other large laboratory species in that they have a short gestation peri...
Although a positive correlation between aneuploidy and maternal age was first reported almost a century ago, the underlying mechanisms remain mostly unknown. Different hypotheses regarding age-related...
Background and Aim: Prenatal diagnosis of chromosome abnormalities is usually performed on amniotic fluid samples. Aneuploidy screening by fluorescence in situ hybridization (FISH), although not an al...
Aim: To investigate the efficacy of quantitative fluorescent-polymerase chain reaction (QF-PCR) in the diagnosis of aneuploidy. Materials and methods: The study included 40 pregnant women considered t...
Reciprocal chromosomal translocations (RCT) have long been recognized as important etiological factors in reproductive failure. In the present study, the meiotic segregation patterns of the sperm...
Previous studies suggest that sperm DNA fragmentation may be associated with aneuploidy. However, currently available tests have not made it possible to simultaneously perform DNA fragmentatio...
Chromosome abnormalities in embryos are a major cause of implantation and development failures. Some couples with normal karyotypes have repeated implantation failures after intracytoplasmic sperm...
The frequencies of aneuploid and diploid spermatozoa were determined in 3 patients presenting a complete asthenozoospermia due to a primary and specific flagellar anomaly: patients 1 and 2 presented...
Infertile patients with abnormal sperm parameters have an increased sperm aneuploidy rate, despite a normal blood karyotype. The evaluation of sperm chromosome aberrations in patients with teratozoo...
Testicular sperm biopsy combined with intracytoplasmic sperm injection (ICSI) allows men with azoospermia the possibility of fathering a child. However, little information exists on the risk of chro...
Toxicological and epidemiological studies have investigated several factors that are believed to induce cytogenetic damage in human sperm cells in an effort to estimate heritable risk to future gene...
