VISEM-Tracking, a human spermatozoa tracking dataset [PDF]

open access: yesSci Data 10, 260 (2023), 2022
A manual assessment of sperm motility requires microscopy observation, which is challenging due to the fast-moving spermatozoa in the field of view. To obtain correct results, manual evaluation requires extensive training. Therefore, computer-assisted sperm analysis (CASA) has become increasingly used in clinics.

Mass Sperm Motility Is Correlated to Sperm Motility as Measured by Computer-Aided Sperm Analysis (CASA) Technology in Farmed Ostriches

open access: yesAnimals, 2022
Semen analyses have gained momentum in various livestock industries. However, in farmed ostriches, semen analysis is still in its experimental stage, and males are not screened for sperm quality before breeding.

Gene Expression and Protein Synthesis in Mitochondria Enhance the Duration of High-Speed Linear Motility in Boar Sperm

open access: yesFrontiers in Physiology, 2019
Sperm motility patterns are continuously changed after ejaculation to fertilization in the female tract. Hyperactivated motility is induced with high glucose medium in vitro or the oviduct fluids in vivo, whereas sperm maintain linear motility in the ...

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 ...

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

open access: yesPLoS 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.

Automated Sperm Assessment Framework and Neural Network Specialized for Sperm Video Recognition [PDF]

open access: yesarXiv, 2023
Infertility is a global health problem, and an increasing number of couples are seeking medical assistance to achieve reproduction, at least half of which are caused by men. The success rate of assisted reproductive technologies depends on sperm assessment, in which experts determine whether sperm can be used for reproduction based on morphology and ...

Identification of key genes affecting sperm motility in chicken based on whole-transcriptome sequencing

open access: yesPoultry Science, 2023
: Sperm motility is an important index for the evaluation of semen quality. Improving sperm motility is important to improve reproductive performance, promote breeding process, and reduce production cost.

Semen quality and sperm DNA fragmentation in cancer patients undergoing sperm cryopreservation [PDF]

open access: yesInvestigative and Clinical Urology, 2023
Purpose: We compared semen quality and sperm DNA fragmentation in cancer patients who underwent sperm banking and controls who underwent sperm cryopreservation for assisted reproductive technology (ART).

Enhanced motility in a binary mixture of active nano/microswimmers [PDF]

open access: yesNanoscale 2020, 2020
It is often desirable to enhance the motility of active nano- or microscale swimmers such as, e.g., self-propelled Janus particles as agents of chemical reactions or weak sperm cells for better chances of successful fertilization. Here we tackle this problem based on the idea that motility can be transferred from a more active guest species to a less ...

Semen collection and evaluation of captive coatis (Nasua nasua)

open access: yesArquivo 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/
