Motility induced changes in viscosity of suspensions of swimming microbes in extensional flows [PDF]

open access: yesarXiv, 2015
Suspensions of motile cells are model systems for understanding the unique mechanical properties of living materials which often consist of ensembles of self-propelled particles. We present here a quantitative comparison of theory against experiment for the rheology of such suspensions.

Relationship between sperm progressive motility and DNA integrity in fertile and infertile men

open access: yesMiddle East Fertility Society Journal, 2018
Background: Progressive sperm motility was found to be predictive for in vitro and in vivo fertilization. There has been an increase in the literature of studies investigating whether DNA fragmentation could be associated with other semen parameters ...

Spermatozoa scattering by a microchannel feature: an elastohydrodynamic model [PDF]

open access: yesarXiv, 2014
Sperm traverse their microenvironment through viscous fluid by propagating flagellar waves; the waveform emerges as a consequence of elastic structure, internal active moments, and low Reynolds number fluid dynamics. Engineered microchannels have recently been proposed as a method of sorting and manipulating motile cells; the interaction of cells with ...

Molecular approaches based on investigating the therapeutic benefits of Moringa oleifera: Insights into biochemical and spermatological and metabolites studies

open access: yesAspects of Molecular Medicine
This study aimed to investigate the potential of Moringa oleifera extract, an herbal treatment known to support male reproductive function, in improving sperm motility. Adult male guinea pigs were divided into four groups (n = 5 per group).
