Motility enhancement of human spermatozoa using electrical stimulation in the nano-Ampere range with enzymatic biofuel cells.

PLoS ONE, 2020
Sperm motility is a crucial factor for normal fertilisation that is partly supported by mitochondrial activity. Enzymatic biofuel cells (EBFCs) generate electric currents by an electron grade from anodic to cathodic electrodes in a culture media.

Semen collection and evaluation of captive coatis (Nasua nasua)

Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2012
Semen samples (n=105) were collected through eletroejaculation from six adult male coatis (Nasua nasua) between January 2007 and December 2008 at Universidade Federal de Mato Grosso Zoo, Cuiabá, Brazil. Mean values were: volume (mL); concentration (sperm/

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

Reproductive 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 ...

Activation of Toll-like receptor 7/8 encoded by the X chromosome alters sperm motility and provides a novel simple technology for sexing sperm

PLoS Biology, 2019
In most mammals, the male to female sex ratio of offspring is about 50% because half of the sperm contain either the Y chromosome or X chromosome. In mice, the Y chromosome encodes fewer than 700 genes, whereas the X chromosome encodes over 3,000 genes ...

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

Reproductive 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.

Integrated analysis of mRNAs and long noncoding RNAs in the semen from Holstein bulls with high and low sperm motility

Scientific Reports, 2019
Sperm motility is the main index used to assess the quality of bull semen. It may also be used to evaluate the fertility potential of bulls. Protein-coding mRNA and long noncoding RNA (lncRNA) participate in the regulation of spermatogenesis.

Adherence to the Mediterranean diet is positively associated with sperm motility: A cross-sectional analysis

Scientific Reports, 2019
The aim of this cross-sectional analysis is to investigate the associations between the adherence to the Mediterranean Diet (MD) and semen quality parameters. To assess the adherence to the MD, the Trichopoulou score was used.

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

Avian 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

Comparative Proteomic Analysis of Proteins Involved in Bioenergetics Pathways Associated with Human Sperm Motility

International Journal of Molecular Sciences, 2019
Sperm motility is the most important parameter involved in the fertilization process and it is strictly required for reproductive success. Although sperm movements are essential for the physiologic fertilization process, the data, deriving from studies ...
