Effect of gonadotropins on chromosome aneuploidy, chromosome mosaicism & sex ratio in mouse preimplantation embryos.
BACKGROUND & OBJECTIVE There are potential risks of major birth defect in IVF (in vitro fertilization) pregnancy as well as IVF-ICSI (intra cytoplasmic sperm injection) pregnancies in comparison with naturally conceived human pregnancies. This increase risk could be due to either gonadotropins used for ovarian stimulation or in vitro culture conditions or multiple pregnancy or combinations of a...
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...
متن کاملSperm DNA fragmentation and sex chromosome aneuploidy after swim-up versus density gradient centrifugation
Objective The aim of this study was to compare the efficacy of swim-up and density gradient centrifugation (DGC) for reducing the amount of sperm with fragmented DNA, sex chromosome aneuploidy, and abnormal chromatin structure. Methods Semen samples were obtained from 18 healthy male partners who attended infertility clinics for infertility investigations and were processed with swim-up and D...
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 کاملAneuploidy Assessment of X, Y, 18 Chromosomes in Sperm of Oligoteratospermia Using FISH Technique
Introduction: Not being to get pregnant, after one year of unprotected sex is called infertility. In the post, infertility was mainly a female problem, but the role of male factors in infertility has denotation, although a greater percentage of this infertility is related to the deficiencies of semen. Methods: This case-control study was performed on sperm samples from 30 infertile oligoterato...
