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.

Impairment of spermatogenesis and sperm motility by the high-fat diet-induced dysbiosis of gut microbes

Gut, 2020
Objective High-fat diet (HFD)-induced metabolic disorders can lead to impaired sperm production. We aim to investigate if HFD-induced gut microbiota dysbiosis can functionally influence spermatogenesis and 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.

Evaluation of Sperm Mitochondrial Function: A Key Organelle for Sperm Motility

Journal of Clinical Medicine, 2020
Introduction: The role of nutraceuticals in the treatment of male infertility, especially in the “idiopathic form”, remains the subject of significant debate.

Current Insights and Latest Updates in Sperm Motility and Associated Applications in Assisted Reproduction

Reproductive Sciences, 2020
Spermatozoon is a motile cell with a special ability to travel through the woman’s reproductive tract and fertilize an oocyte. To reach and penetrate the oocyte, spermatozoa should possess progressive motility.

Analyses of Long Non-Coding RNA and mRNA profiling using RNA sequencing in chicken testis with extreme sperm motility [PDF]

Scientific Reports, 2017
Sperm motility is the most important indicator in evaluating roosters’ fecundity. However, the genetic mechanisms underlying chicken sperm motility is not yet clear. Long non-coding RNA (lncRNA) play epigenetic roles in reproduction.

Exogenous Oleic Acid and Palmitic Acid Improve Boar Sperm Motility via Enhancing Mitochondrial Β-Oxidation for ATP Generation

Animals, 2020
Simple Summary Sperm requires ATP production for maintaining motility. In boar sperm, it is not clear whether the mitochondrial β-oxidation pathway for ATP generation is active or not.

Mitochondrial Membrane Potential Predicts 4-Hour Sperm Motility

Biomedicines, 2020
The evaluation of conventional and biofunctional sperm parameters is of fundamental importance for assessing male reproductive function. Among these, sperm motility is one of the most important parameters. Indeed, asthenozoospermia is a frequent cause of

Mass Sperm Motility Is Correlated to Sperm Motility as Measured by Computer-Aided Sperm Analysis (CASA) Technology in Farmed Ostriches

Animals, 2022
Semen analyses have gained momentum in various livestock industries. However, in farmed ostriches, semen analysis is still in its experimental stage, and males are not screened for sperm quality before breeding.
