Spermatogenesis in the testicle is controlled by a finely coordinated, complex interplay of the activity of different genes -- also known as gene expression. Hitherto the understanding of these ...

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 ...

Many of these genes are related to the process of spermatogenesis, meaning that these associated genes may serve as male fertility biomarkers. Further to this, studies in the past decade have also ...

You produce sperm every day, but a full sperm regeneration cycle (spermatogenesis) takes about 64 days. Spermatogenesis is the complete cycle of sperm production and maturation. It constantly ...

Infertility and very low levels of spermatogenesis persist in the affected men, despite long-term exposure to human chorionic gonadotropin, suggesting that the absence of perinatal exposure to ...

A blood specimen from a man with normal spermatogenesis was used as a positive control, and one from a woman was used as a negative control. For each sample, first-strand complementary DNA was ...

Clinical Level The study of NPs and spermatogenesis at the clinical level measures body weight, organ weight, oxidative stress indicators and NP concentration/content indices, generally in mice or ...

However, urine proteomics has not been studied for monitoring spermatogenesis, the process where spermatogonial cells divide and differentiate into mature sperm. In a study by researchers from ...

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 ...

In this review, we focus mainly on the in vivo and in vitro effects of NPs on spermatogenesis at the clinical, cellular and molecular levels. In general, most NPs display adverse effects on ...
