Correlative Study of Sperm Motility and Mitochondrial Membrane Potential by Fluorescent Staining: First Application in Iraqi Centers [PDF]

open access: yesAl-Anbar Medical Journal
Background: Sperm motility is an essential factor in ensuring the fertility of males. Sperm mitochondria play a significant role in the generation of energy as well as the metabolism of sperm.

Computerized Sperm Motility and Application of Sperm Cryopreservation [PDF]

open access: yesArchives of Andrology, 1988
An objective method for measuring sperm motion characteristics was developed on an Intellect 100 Quantel Image Analysis System suitable for various image cytometric applications. It provided overall analysis of percent motility (% MS) as well as individual and mean measurements of motion characteristics, including vigor characteristics such as ...

IL1R2 Marks and Sorts a Spermatogonial Stem Cell Population Critical for Restoring Spermatogenesis Upon Interruption in Mammals

open access: yesAdvanced Science, EarlyView.
Spermatogonial stem cells (SSCs) provide critical support to spermatogenesis. Here, the author established Il1r2 as a sorting marker for SSCs, with which further insights into the SSC heterogeneity and dynamic features can be obtained. They also confirmed findings in both mouse and human, thus validating IL1R2 as the surface marker for isolating and ...

Effects of L-carnitine and L-acetyl-carnitine on testicular sperm motility and chromatin quality [PDF]

open access: yesIranian Journal of Reproductive Medicine, 2012
Background: Sperm cells extracted from testes (TESE) have poor chromatin quality and motility. Various substances are used in the laboratory to increase sperm motility and improve the ART outcomes; however, there are few research which considered ...

Use of endocrine and immune responses as predictors of bull sperm motility [PDF]

open access: yes, 2015
Research has shown that peripheral blood cell populations change in response to an immune challenge, and hormone concentrations directly affect sperm characteristics.

Differences in ATP generation via glycolysis and oxidative phosphorylation, and relationships with sperm motility, in mouse species [PDF]

open access: yes, 2015
Mouse sperm produce enough ATP to sustain motility by anaerobic glycolysis and respiration. However, previous studies indicated that an active glycolytic pathway is required to achieve normal sperm function, and identified glycolysis as the main source ...

TSHR‐Targeting Nucleic Acid Aptamer Treats Graves' Ophthalmopathy via Novel Allosteric Inhibition

open access: yesAdvanced Science, EarlyView.
This study presents YC3, a novel inhibitory TSHR‐targeting aptamer, as a promising therapeutic for Graves' ophthalmopathy (GO). YC3 suppresses pathological phenotypes in human orbital fibroblasts and improves outcomes in GO mice by binding to a previously unidentified allosteric site on TSHR, demonstrating the potential of aptamers in advancing ...

Validation of the polysemen admixture on viability and acrosomal morphology of boar spermatozoa [PDF]

open access: yes, 2007
Semen were collected using artificial vagina (AV), from 5 large white boars aged 2-2.5 years twice a week for 16 weeks in each of the two seasons, early rainy (ER) and late rainy (LR) seasons, to determine the effects of multiple semen pool admixture on ...

Differential Sperm Motility Scoring and Sperm ATP Concentrations [PDF]

open access: yesArchives of Andrology, 1993
Sperm motility is one of the most important parameters in semen analysis. In this study the motility scoring method of Hellinga was used. Adenosine triphosphate (ATP) is the main energy source used by the sperm flagellum to initiate and propagate forward motility.
