abstract：:The GIRK2-containing inward-rectifying K(+) ion channels have been implicated in mammalian spermatogenesis. While the Girk2 null mice are fertile, the male weaver transgenic mice carrying a gain-of-function mutation in the Girk2 gene are infertile. To establish the exact period of spermatogenesis affected by this muta...

abstract：:Sperm progressive motility has been reported to be one of the key factors influencing in vitro fertilization rates. However, recent studies have shown that sperm DNA fragmentation is a more robust predictor of assisted reproductive outcomes including reduced fertilization rates, embryo quality, and pregnancy rates. Th...

abstract：:For natural fertilization to occur successfully, millions of spermatozoa must be deposited in the lower end of the female genital tract during mating. Considerably fewer spermatozoa are required for fertilization when spermatozoa are deposited in the upper region of the female tract. The extreme case of assisted ferti...

abstract：:Reproductive biology is considered a specialty field, however, an argument can be made that it is instead generally applicable to many fields of biology. The one-cell embryo is presented here as a model system for the study of eukaryotic DNA replication, apoptotic DNA degradation, and signaling mechanisms between the ...

abstract：:Genomic disorders are defined as diseases caused by rearrangements of the genome incited by a genomic architecture that conveys instability. Y-chromosome related dysfunctions such as male infertility are frequently associated with gross DNA rearrangements resulting from its peculiar genomic architecture. The Y-chromos...

abstract：:In the human, canonical histones are largely replaced by protamine 1 (P1) and protamine 2 (P2) during late spermatogenesis. Recent studies have demonstrated that abnormal replacement of the histones is associated with severe male infertility and has profound implications for early embryogenesis. In this review the his...

abstract：:Assessment of sperm DNA damage has been suggested as a negative predictor of fertility potential. Multiple pathological factors acting at both the intra-testicular and post-testicular levels may contribute to sperm DNA damage. The relative contribution of each of these factors in an individual with high DNA damage (>3...

abstract：:During spermatogenesis, changes in sperm nuclear morphology are associated with the replacement of core somatic histones by protamines. Although protamines are the major nucleoproteins of mature sperm, not all species totally replace the histones. Histone H1, along with protamines, mediates chromatin condensation into...
