Therapeutic Repair of Sperm Quality Decline Caused by Polytetrafluoroethylene

Advanced Science, EarlyView.
Exposure to PTFE (teflon), a commonly used microplastic in non‐stick cookware, significantly reduces sperm quality in both humans and mice. Specifically, PTFE induces the disruption of sperm cytoskeleton and F‐actin assembly through targeting SKAP2 in haploid spermatid.

Effects of dioxins on animal spermatogenesis: A state-of-the-art review

Frontiers in Reproductive Health, 2022
The male reproductive system is especially affected by dioxins, a group of persistent environmental pollutants, resulting in irreversible abnormalities including effects on sexual function and fertility in adult males and possibly on the development of ...

Testicular degeneration and infertility following arbovirus infection [PDF]

, 2018
Arboviruses can cause a variety of clinical signs including febrile illness, arthritis, encephalitis and hemorrhagic fever. The recent Zika epidemic highlighted the possibility that arboviruses may also negatively affect the male reproductive tract.

The Function of Pre-mRNA Alternative Splicing in Mammal Spermatogenesis

International Journal on Biological Sciences, 2020
Alternative pre-mRNA splicing plays important roles in co-transcriptional and post-transcriptional regulation of gene expression functioned during many developmental processes, such as spermatogenesis.

The Endocannabinoid System and Spermatogenesis [PDF]

Frontiers in Endocrinology, 2013
Spermatogenesis is a complex process in which male germ cells undergo a mitotic phase followed by meiosis and by a morphogenetic process to form mature spermatozoa. Spermatogenesis is under the control of gonadotropins, steroid hormones and it is modulated by a complex network of autocrine and paracrine factors.

Genomic Insights into the Origin, High Fecundity and Environmental Adaptation of Hu Sheep

Advanced Science, EarlyView.
The Hu sheep diverged from the Small‐tailed Han sheep ≈1330 years ago, and subsequently migrated from northern to warm and humid southern regions. The genes BMPR1B, UNC5C, and GRID2 play a synergistic role in the superior reproductive traits of Hu sheep.

Androgens and spermatogenesis

Annales d'Endocrinologie, 2022
Male infertility contributes to 50% of all cases of infertility. The main cause is low quality and quantity of sperm. In humans, spermatogenesis starts at the beginning of puberty and lasts lifelong. It is under the control of FSH and testicular androgens, and mainly testosterone (T), and therefore requires a normal gonadotroph axis, intratesticular T ...

Application of testicular organ culture system for the evaluation of spermatogenesis impairment

Scientific Reports
Recently, it was reported that a testicular organ culture system (TOCS) using polydimethylsiloxane (PDMS) chips with excellent oxygen permeability and biocompatibility, called the PDMS-chip ceiling (PC) method, enables improved spermatogenesis efficiency.

Molecular cloning and expression of a new gene, GON-SJTU1 in the rat testis

Reproductive Biology and Endocrinology, 2010
Background Spermatogenesis is a complex process involving cell development, differentiation and apoptosis. This process is governed by a series of genes whose expressions are highly regulated.
