Association of Oxidative Stress and Energy Metabolism with Sperm Quality in Chinese Male Adults [PDF]
Background Oxidative stress and energy metabolism are important factors that affect sperm quality in male individuals. However, the majority of available studies are based on animal models, and evidence from human studies is still inadequate.

Sperm motility and viability of experimental animals using different cryopreservatives
In this study, an experiment was conducted in order to determine what cryopreservatives (CPVs) were more effective in supporting the motility and viability of sperm from experimental animals.

Assessing coral sperm motility [PDF]
AbstractThe declining reproductive viability of corals threatens their ability to adapt to changing ocean conditions. It is vital that we monitor this viability quantitatively and comparatively. Computer-assisted sperm analysis (CASA) systems offer in-depth analysis used regularly for domestic and wildlife species, but not yet for coral.

Background It is estimated that approximately 8–12% of couples globally face problems associated with infertility. A large number of men exhibit suboptimal sperm parameters.

Many endocrine disruptors may interfere with sperm motility, hyperactivation, and capacitation, thereby leading to male infertility. In the current study, we screened 14 endocrine disruptors, including plant ingredients, cigarette ingredients, minerals ...

Abnormal Human Sperm Parameters Contribute to Sperm DNA Fragmentation in Men with Varicocele [PDF]
Purpose: This study was performed to evaluate and compare threshold sperm parameters and sperm DNA fragmentation index (DFI), and further analyzed whether sperm DFI could be predicted from sperm parameters in men with varicocele.

Motility Assessment of Ram Spermatozoa
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,

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
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.
