Patients with abnormal sperm parameters have an increased sex chromosome aneuploidy rate in peripheral leukocytes.
BACKGROUND Patients with oligoasthenoteratozoospermia (OAT) and normal karyotypes have an increased sperm aneuploidy rate. This may be due to an altered intratesticular environment that affects the chromosomal segregation mechanism(s). Alternatively, it may be due to a generalized meiotic and mitotic abnormality. In this case, patients with abnormal spermatogenesis should also have an increased...
متن کاملMorphologically normal spermatozoa of patients with secretory oligo-astheno-teratozoospermia have an increased aneuploidy rate.
BACKGROUND Normal morphology is a major criterion for selecting spermatozoa to be injected. Given that teratozoospermia is one of the most critical parameters associated with sperm aneuploidy, the purpose of this study was to evaluate the aneuploidy rate of morphologically normal spermatozoa of patients with oligo-astheno-teratozoospermia (OAT). METHODS Ten patients with secretory OAT and six...
متن کاملSperm aneuploidy and meiotic sex chromosome configurations in an infertile XYY male.
BACKGROUND There is little information regarding the behaviour of the extra Y chromosome during meiosis I in men with 47,XYY karyotypes and the segregation of the sex chromosomes in sperm. We applied immunofluorescent and FISH techniques to study the relationship between the sex chromosome configuration in meiotic germ cells and the segregation pattern in sperm, both isolated from semen samples...

متن کاملSex Chromosome Aneuploidy: Prospective Studies on Children
This two-volume publication contains the proceedings of a NATO Advanced Study Institute, held in April 1978. The material is organized in five sections. In the first section J. Bonner presents a historic review of chromatin research. The following section describes biophysical and chemical methods used in the study of isolated chromatin, such as electron microscopy, circular dichroism, X-ray di...
