Disorders in genetic imprinting are discussed as potential genetic risk in assisted
reproduction technology (ART), where most of the natural selection mechanisms are …

Background Altered sperm DNA methylation patterns of imprinted genes as well as certain
spermatogenesis-related genes has been proposed as a possible mechanism of male …

Recent studies suggest that assisted reproductive technologies (ART), which involve the
isolation, handling and culture of gametes and early embryos, are associated with an …

OBJECTIVE: To evaluate the associations between proper protamine incorporation and
DNA methylation at imprinted loci. DESIGN: Experimental research study. SETTING …

Imprinted genes are expressed either from the paternal or the maternal allele, because the
other allele has been silenced in the mother's or father's germline. Imprints are characterized …

Male factor infertility has been associated with abnormal DNA methylation at imprinted
genes. Little information is available on the status of imprinting in the sperm of men with …

The topic of imprinting defects present in the sperm of infertile patients has been addressed
by several reports in the last few years. However, whether methylation abnormalities at one …

Genomic imprinting marks in the male germ line are already established in the adult
germinal stem cell population. We studied the methylation patterns of H19 and MEST …

Considering the widespread use of assisted reproductive techniques (ART), DNA
methylation of specific genes involved in spermatogenesis achieves increasingly clinical …

Purpose To evaluate the association between the DNA methylation of specific genes and
sperm DNA integrity status in human sperm samples. Methods A total of 166 semen samples …
