Molecular Dissection Using Array Comparative Genomic Hybridization and Clinical Evaluation of An Infertile Male Carrier of An Unbalanced Y;21 Translocation: A Case Report and Review of The Literature [PDF]

open access: yesInternational Journal of Fertility and Sterility, 2016
Chromosomal defects are relatively frequent in infertile men however, translocations between the Y chromosome and autosomes are rare and less than 40 cases of Y-autosome translocation have been reported.

The outcomes of fetal cell microchimerism in the mother

open access: yesBiomedical Research Journal, 2021
The presence of small quantities of genetically heterogeneous cells in an organism is known as microchimerism. Fetal microchimerism is the presence of small quantities of fetal cells in the maternal system during and after pregnancy.

Assessment of Correlation between Androgen Receptor CAG Repeat Length and Infertility in Infertile Men Living in Khuzestan, Iran [PDF]

open access: yesInternational Journal of Fertility and Sterility, 2015
Background The androgen receptor (AR) gene contains a polymorphic trinucleotide repeat that encodes a polyglutamine tract in its N-terminal transactivation domain (N- TAD).

Association of X Chromosome Aberrations with Male Infertility

open access: yesActa Medica Bulgarica, 2021
Male infertility is caused by spermatogenetic failure, clinically noted as oligoor azoospermia. Approximately 20% of infertile patients carry a genetic defect.

Assembly of the threespine stickleback Y chromosome reveals convergent signatures of sex chromosome evolution

open access: yesGenome Biology, 2020
Heteromorphic sex chromosomes have evolved repeatedly across diverse species. Suppression of recombination between X and Y chromosomes leads to degeneration of the Y chromosome. The progression of degeneration is not well understood, as complete sequence

Quantitative analysis of Y-Chromosome gene expression across 36 human tissues

open access: yesGenome Research, 2020
Little is known about how human Y-Chromosome gene expression directly contributes to differences between XX (female) and XY (male) individuals in nonreproductive tissues.

The Y chromosome may contribute to sex-specific aging in Drosophila

open access: yesNature Ecology & Evolution, 2020
Heterochromatin suppresses repetitive DNA, and a loss of heterochromatin has been observed in aged cells of several species, including humans and Drosophila.

48,XYYY: A Rare Case Report

open access: yesBalkan Journal of Medical Genetics, 2022
A case study of a 4 year old child with hypospadias and cryptorchidism on the right side is presented. Combined analysis by Karyotype and FISH showed a mosaic pattern of 48, XYYY (73%); 47,XYY (7%); 46,XY (7%) and 45,X (13%).

Lack of Association Between Partial Y chromosome AZFc-gr/gr Deletions and Male Infertility

open access: yesBioMed Target Journal, 2023
A microdeletion in the azoospermia factor (AZF) region of the human Y chromosome long arm is the second most common genetic factor causing male infertility and spermatogenetic failure. The current study aimed to evaluate the occurrence of AZFc-partial gr/

A family case of fertile human 45,X,psu dic(15;Y) males [PDF]

open access: yes, 2006
We report on a familial case including four male probands from three generations with a 45,X,psu dic(15;Y)(p11.2;q12) karyotype. 45,X is usually associated with a female phenotype and only rarely with maleness, due to translocation of small Y chromosomal
