Chromosome patterns and gonadal functions were analysed in two male prison inmates with XYY chromosomes. Both had no extra Y-chromosome in the germinal cells (spermatogonia, spermatocides of the first order), contrary to the findings in other tissues. Urinary gonadotropin excretion was normal. The...
The global frequencies of sperm with an abnormal number of sex chromosomes ranged from 0.578 to 13.91%, depending on the patients. There are several explanations for these discrepancies: differences attributed to fluorescence in situ hybridization methodology, the use of dual or multicolor FISH, ...
To determine the incidence of sex chromosome aneuploidy in the sperm of two men with a 47,XYY/46,XY karyotype. Case report. Infertility clinic in a teaching hospital. One patient with near normal semen parameters whose wife had a history of miscarriages and one patient with primary infertility...
Our sex is determined by the X and Y chromosomes. Usually, girls have two X chromosomes (XX) and boys have one X and one Y (XY), but approximately one in 500 boys are born with an extra X or Y, and having three rather than two sex chromosomes can disrupt formation of mature sperm...
identified three women with detectable chromosome Y in a proportion of cells, then likely corresponding to X0/XY mosaicism and a possible diagnosis of Turner syndrome, as well as three individuals with non-mosaic XYY (Fig.2c). We observed 6 men with both LOY and mCA, 220 with LOY and ...
X and autosomal chromosomes from the normotensive WKY rat and another with the opposite configuration.25 Such techniques revealed that the Y chromosome independently raised blood pressure by 34 mm Hg.25 A later review by Ely et al26 estimated the Y effect on blood pressure at a more modest 15...
The aim of this study was to investigate the neuroendocrine integrity of the pituitary-gonadal axis in patients with primary testicular failure due to supernumerary X chromosomes. DESIGN: Cross-sectional study. METHODS: In this study, 7 untreated patients with primary gonadal insufficiency due to SRY...
Objective(s): To determine the copy number and identity of the DAZ genes on the Y chromosomes of infertile patients. Design: Prospective study. Setting: University medical center. Patient(s): One hundred and thirty-nine patients with male factor infertility. Intervention(s): The separate genes ...
The remainder either had one of the recognized psychoses, or were epileptics, or had brain damage as the result of previous or trauma.Sixteen of the 315 men examined (5.1%) had an abnormal chromosomes complement detectable in mitotic cells. Of these 9 were 47, XYY, one 48,XXY, one 46,...
