Rheotaxis-based separation of sperm with progressive motility using a microfluidic corral system
Proceedings of the National Academy of Sciences of the United States of America, 2018 Significance The separation of motile sperm from semen samples is required for medical infertility treatments and clinical studies. Conventional methods are time- and labor-intensive and could be potentially hazardous to morphology and paternal content ...

Sperm DNA fragmentation and oxidation are independent of malondialdheyde
Reproductive Biology and Endocrinology, 2011 Background There is clinical evidence to show that sperm DNA damage could be a marker of sperm quality and extensive data exist on the relationship between DNA damage and male fertility status.

The In Vitro Impact of the Herbicide Roundup on Human Sperm Motility and Sperm Mitochondria
Toxics, 2016 Toxicants, such as herbicides, have been hypothesized to affect sperm parameters. The most common method of exposure to herbicides is through spraying or diet. The aim of the present study was to investigate the effect of direct exposure of sperm to 1 mg/

Serum lipid profiles are associated with semen quality
Asian Journal of Andrology, 2017 We aimed to explore the associations between different lipid profiles and semen quality in a large-scale general male population. Sperm concentration, total sperm motility, progressive motility, and normal sperm morphology of total 7601 participants were

Sodium–hydrogen exchanger NHA1 and NHA2 control sperm motility and male fertility
Cell Death and Disease, 2016 Our previous work identified NHA1, a testis-specific sodium–hydrogen exchanger, is specifically localized on the principal piece of mouse sperm flagellum.

Rosiglitazone Improves Stallion Sperm Motility, ATP Content, and Mitochondrial Function1
Biology of Reproduction, 2016 Media used for equine sperm storage often contain relatively high concentrations of glucose, even though stallion spermatozoa preferentially utilize oxidative phosphorylation (OXPHOS) over glycolysis to generate ATP and support motility. Rosiglitazone is

Major regulatory mechanisms involved in sperm motility
Asian Journal of Andrology, 2015 The genetic bases and molecular mechanisms involved in the assembly and function of the flagellum components as well as in the regulation of the flagellar movement are not fully understood, especially in humans.

Di (2-ethylhexyl) phthalate reduces sperm motility by decreasing sperm tail energy supply
Ecotoxicology and Environmental SafetyDi (2-ethylhexyl) phthalate (DEHP) is widespread in the environment. It can impair sperm function through damaging the sperm development process. However, few studies have focused on the sperm tail that is directly related to sperm motility.
