Influence of sperm cryopreservation on sperm motility and proAKAP4 concentration in mice

open access: yesReproductive Medicine and Biology, 2022
Background The protein proAKAP4 is crucial for sperm motility and has been suggested as an indicator of male fertility. We determined the relationship between proAKAP4 concentration and sperm motility parameters in mice, and investigated the effects of ...

A microfluidic method for passive trapping of sperms in microstructures [PDF]

open access: yesarXiv, 2022
Sperm motility is a prerequisite for male fertility. Enhancing the concentration of motile sperms in assisted reproductive technologies - for human and animal reproduction - is typically achieved through aggressive methods such as centrifugation. Here we propose a passive technique for the amplification of motile sperm concentration, with no externally

Transcriptome analysis of the testes of male chickens with high and low sperm motility

open access: yesPoultry 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

Optimal analysis conditions for sperm motility parameters with a CASA system in a passerine bird, Passer montanus

open access: yesAvian Research, 2019
Background Sperm motility parameters, which can be measured objectively and repeatedly by a computer-assisted sperm analysis (CASA) system, are important indicators of sperm quality. However, the sperm motility parameters assessed by a CASA system can be

Detection of Plasma Membrane Alpha Enolase (ENO1) and Its Relationship with Sperm Quality of Bali Cattle

open access: yesTropical Animal Science Journal, 2023
Bali cattle are the indigenous cattle well known attributed to their high fertility. Various proteomes in sperm are substances that can determine sperm quality and fertility. One of which is alpha enolase (ENO1).

High concentration of dopamine treatment may induce acceleration of human sperm motility

open access: yesReproductive Medicine and Biology, 2022
Purpose In humans, catecholamines (including dopamine) have been identified in semen and fallopian tubes, while dopamine D2 receptors (D2DR) are found in the sperm midpiece region.

Surfing along concentration filaments: sperm chemotaxis in physiological shear flows [PDF]

open access: yesPLoS Comput Biol 17(4) e1008826 (2021), 2019
Many motile biological cells navigate along concentration gradients of signaling molecules: This chemotaxis guides for instance sperm cells from marine invertebrates, which have to find egg cells in the ocean. While chemotaxis has been intensively studied for idealized conditions of rotationally symmetric gradients in still water, natural gradients are
