Motility Assessment of Ram Spermatozoa
Biology, 2022 For successful fertilisation to occur, spermatozoa need to successfully migrate through the female reproductive tract and penetrate the oocyte. Predictably, poor sperm motility has been associated with low rates of fertilisation in many mammalian species,

Archives of Andrology, 1998 Within 40 s the Sperm Quality Analyzer (United Medical Systems, Santa Ana, CA, USA) provides a numerical value called the sperm motility index. This index reflects both the concentration of motile sperm cells and the intensity of their motility and cannot be determined by conventional semen analysis.

Sperm Motility Regulation in Male and Female Bird Genital Tracts
The Journal of Poultry Science, 2022 Sperm drastically change their flagellar movement in response to the surrounding physical and chemical environment. Testicular sperm are immotile; however, they gain the competence to initiate motility during passage through the male reproductive tract.

Transcriptome analysis of the testes of male chickens with high and low sperm motility
Poultry Science, 2022 : The reproductive performance of chicken breeders has significant economic importance in the poultry industry, and sperm motility is an indicator of reproductive performance. This study performed RNA-seq of the testes of Gushi chicken roosters with high

Human sperm RNA code senses dietary sugar. [PDF]
, 2020 A new study reveals that a high-sugar diet acutely alters human sperm small RNA profiles after 1 week and that these changes are associated with changes in sperm motility.

Molecular Changes Induced by Oxidative Stress that Impair Human Sperm Motility
Antioxidants, 2020 A state of oxidative stress (OS) and the presence of reactive oxygen species (ROS) in the male reproductive tract are strongly correlated with infertility.
