Elevated Lipid Concentrations in Seminal Plasma Can Reduce Sperm Motility in Simmental Bulls [PDF]

open access: yesAnimals
Sperm motility is a key factor influencing male fertility and is associated with metabolic and lipid profiles across species. The aim of this study was to investigate the relationship between sperm motility and the seminal plasma lipid profile in ...

Effect of electroacupuncture on total motile sperm count and sperm motility. [PDF]

open access: yesJ Public Health Res
Background: Approximately 50% of infertility cases are attributed to male factors. Acupuncture has long been employed as a complementary therapy to enhance male infertility treatment outcomes. This study aimed to assess the impact of electroacupuncture (EA) therapy on sperm motility and TMSC in male infertility patients.

Male sperm storage compromises sperm motility in guppies [PDF]

open access: bronzeBiology Letters, 2014
Sperm senescence can have important evolutionary implications due to its deleterious effects on sperm quality and offspring performance. Consequently, it has been argued that polyandry (female multiple mating) may facilitate the selection of younger, and therefore competitively superior, sperm when ejaculates from multiple males compete ...

Association of Oxidative Stress and Energy Metabolism with Sperm Quality in Chinese Male Adults [PDF]

open access: yesZhongguo quanke yixue, 2023
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

open access: yesJournal of Animal Reproduction and Biotechnology, 2023
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]

open access: yesScientific Reports, 2021
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.

Understanding sperm motility mechanisms and the implication of sperm surface molecules in promoting motility

open access: yesMiddle East Fertility Society Journal, 2022
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.

Inhibition of human sperm motility and capacitation by ziram is mediated by decreasing tyrosine protein kinase

open access: yesEcotoxicology and Environmental Safety, 2021
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]

open access: yesThe World Journal of Men's Health, 2018
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

open access: yesBiology, 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,
