Fluorescence In Situ Hybridization Studies of Sperm Aneuploidies in Infertile Men
Fluorescence in situ hybridization analysis, performed with chromosome specific DNA probes labeled with fluorochromes, is a simple and reliable tool for the indirect study of aneuploidies in interphase cells such as spermatozoa. It is known that infertile male patients with poor sperm quality, due to different causes, produce cytogenetically abnormal spermatozoa despite a normal constitutional ...
متن کاملFluorescence in situ hybridization detects increased sperm aneuploidy in men with recurrent pregnancy loss.
OBJECTIVE To investigate, in men presenting with recurrent pregnancy loss (RPL), the prevalence of sperm autosome and sex chromosome aneuploidy. DESIGN Retrospective study. SETTING Male infertility clinic. PATIENT(S) A total of 140 men with RPL provided semen samples, and five normozoospermic controls provided 140 semen samples for comparison. Recurrent pregnancy loss, documented in the f...
متن کاملFluorescence in situ hybridization (FISH) Protocol in Human Sperm
Aneuploidies are the most frequent chromosomal abnormalities in humans. Most of these abnormalities result from meiotic errors during the gametogenic process in the parents. In human males, these errors can lead to the production of spermatozoa with numerical chromosome abnormalities which represent an increased risk of transmitting these anomalies to the offspring. For this reason, the techniq...
متن کاملSperm Identification in Maize by Fluorescence in Situ Hybridization.
The two sperm cells of common origin within the pollen tube of flowering plants are each involved in a fertilization event. It has long been recognized that preferential fusion of one sperm with the egg can occur in B chromosome-containing lines of maize. If the second pollen mitosis begins with a single B chromosome, nondisjunction will result in one sperm possessing two B chromosomes and the ...
متن کاملSexing of Dog Sperm by Fluorescence In Situ Hybridization
Effective preselection of sex has been accomplished in several species of livestock and also in humans using the flow cytometric sperm sorting method. A guaranteed high sorting accuracy is a key prerequisite for the widespread use of sperm sexing. The standard validation method is flow cytometric remeasurement of the DNA content of the sexed sperm. Since this method relies on the same instrumen...
