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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

According to the American Cancer Society, survivors of childhood cancer can face health problems later in their adult life. Many boys who undergo cancer treatment before puberty can lose the ability ...
