Evidence has led experts to believe that genetics may be accountable for the difficulties that a significant portion of couples face when trying to conceive a child. Because men are just as likely to ...

The physiological function of spermatogenesis in Caenorhabditis elegans, Drosophila melanogaster and mammals is to produce spermatozoa (In, haploid) that contain only half of the genetic material of ...

An ultrastructural analysis of spermatogenesis in the liverwort Blasia pusilla was undertaken to consider, in detail, the development of the spermatogenous tissue, the origin and ontogeny of the ...

A large German study has shown that spermatogenesis is markedly reduced in the contralateral testis of patients with testicular germ cell tumors (GCTs). This finding supports the hypothesis of ...

Male infertility is on the rise, with significant declines in sperm quantity and quality occurring across the human population worldwide in the past two decades. The reason for this is poorly ...

A new gene that controls the completion of meiosis in spermatogenesis has been discovered. Until now, details of the mechanism that inactivates the expression of genes involved in the meiotic program ...

Urine is sensitive to bodily changes and can distinguish normozoospermic infertile men from fertile ones through metabolomics. However, urine proteomics has not been studied for monitoring ...

Researchers have unmasked the functioning of a protein involved in DNA repair, ATR, in the meiotic recombination process which takes place during the development of spermatocytes -- sperm precursor ...

Researchers at the Francis Crick Institute studying male mice engineered with different Y chromosome deletions have uncovered which genes on the mouse Y chromosome regulate the development of sperm ...
