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 ...

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 ...

The testicle, where sperm is produced, is a very complex tissue, explains Dr. Laurentino. This is why the "instructions" behind spermatogenesis remained unknown until now. The research group achieved ...

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 ...

Mutations that abolish the activity of luteinizing hormone are rare; they have been reported in five men and one woman. 1–5 The phenotypes of these persons suggest that luteinizing hormone is not ...

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 ...

Testicles of most mammals are cooled in the scrota, and elevated testicular temperatures lead to spermatogenesis failure and male infertility. A research team led by Shosei Yoshida at the National ...

The mitochondrion has long been dubbed as the “powerhouse of the cell,” but there’s still much to learn about its inner workings during development and disease formation. Research recently published ...
