Environmental Exposure of Sperm Sex-Chromosomes: A Gender Selection Technique
Preconceptual sex selection is still a highly debatable process whereby X- and Y-chromosome-bearing spermatozoa are isolated prior to fertilization of the oocyte. Although various separation techniques are available, none can guarantee 100% accuracy. The aim of this study was to separate X- and Y-chromosome-bearing spermatozoa using methods based on the viability difference between the X- and Y...
متن کاملSEX SELECTION Elective Gender Selection, Preimplantation Genetic Diagnosis, Pgd, Sperm Sorting, Ericsson Method
Following ethical issues, many of unwanted pregnancies and abortions can be avoided. Several factors such as cultural, social, religious, and economic issues, as well as medical reasons such as the existence of some diseases related to chromosome X encourage couples to choose traditional or new treatment methods for selecting their child’s gender.

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...
متن کاملSignatures of sex-antagonistic selection on recombining sex chromosomes.
Sex-antagonistic (SA) selection has major evolutionary consequences: it can drive genomic change, constrain adaptation, and maintain genetic variation for fitness. The recombining (or pseudoautosomal) regions of sex chromosomes are a promising setting in which to study SA selection because they tend to accumulate SA polymorphisms and because recombination allows us to deploy the tools of molecu...
متن کاملEnvironmental exposure to pyrethroids and sperm sex chromosome disomy: a cross-sectional study
BACKGROUND The role of environmental pesticide exposures, such as pyrethroids, and their relationship to sperm abnormalities are not well understood. This study investigated whether environmental exposure to pyrethroids was associated with altered frequency of sperm sex chromosome disomy in adult men. METHODS A sample of 75 subjects recruited through a Massachusetts infertility clinic provide...
