Colloidal centrifugation of stallion semen results in a reduced rate of sperm DNA fragmentation [PDF]

open access: yes, 2013
Stallion spermatozoa recovered and examined immediatelyafter colloidal centrifugation resulted in a higher straight-linevelocity (VSL) than sperm processed using direct conven-tional centrifugation (p = 0.000), but there was nodifferences in the

Oocyte–cumulus cell interaction: a key factor in early embryo development

open access: yesBiological Reviews, EarlyView.
ABSTRACT The evaluation of oocyte competence is a fundamental step in achieving successful outcomes following assisted reproduction techniques (ART). At present, however, conventional oocyte maturation assessment is carried out by morphological observation, which is a subjective method that does not consider molecular features.

Recombinant Monoclonal Antibodies for Detecting the Tubulin Post‐Translational Modifications Glutamylation and Lysine‐40 Acetylation

open access: yesCytoskeleton, EarlyView.
ABSTRACT Post‐translational modifications (PTMs) to tubulin subunits in microtubule filaments are thought to comprise a component of the tubulin code that specifies microtubule functions in cell physiology and animal development. Acetylation of Lysine‐40 (K40) on α‐tubulin (αTub‐K40ac) and glutamylation of both α‐ and β‐tubulin are two tubulin PTMs of ...

Measuring Sperm DNA Fragmentation and Clinical Outcomes of Medically Assisted Reproduction: A Systematic Review and Meta-Analysis.

open access: yesPLoS ONE, 2016
Sperm DNA fragmentation has been associated with reduced fertilization rates, embryo quality, pregnancy rates and increased miscarriage rates. Various methods exist to test sperm DNA fragmentation such as the sperm chromatin structure assay (SCSA), the ...

The Influence of Drosophila Spire and Myosin V During Mid‐Oogenesis Is Independent of Their Direct Interaction

open access: yesCytoskeleton, EarlyView.
ABSTRACT Cooperativity between cytoskeletal proteins is crucial for spatiotemporal coordination in biological processes, like oogenesis. In mammalian and Drosophila oogenesis, proper assembly and function of actin networks require coordination between actin assembly factors Spire and formins, as well as actin‐associated proteins like myosins and Rab ...

Optimizing outcomes in intrauterine insemination: A narrative synthesis of two decades of clinical research (2000–2024)

open access: yesInternational Journal of Gynecology &Obstetrics, EarlyView.
Abstract Intrauterine insemination (IUI) is a widely used first‐line fertility treatment, yet its success rates vary considerably. This review synthesizes evidence from peer‐reviewed studies published between 2000 and 2024, including randomized controlled trials, cohort and case–control studies, as well as systematic and narrative reviews identified ...

From pathophysiology to practice: addressing oxidative stress and sperm DNA fragmentation in Varicocele-affected subfertile men [PDF]

open access: yesInternational Brazilian Journal of Urology
Varicocele can reduce male fertility potential through various oxidative stress mechanisms. Excessive production of reactive oxygen species may overwhelm the sperm's defenses against oxidative stress, damaging the sperm chromatin. Sperm DNA fragmentation,

Sperm DNA fragmentation and its influence on mammalian reproduction [PDF]

open access: yes
Sperm DNA fragmentation is a recognized factor in male infertility with direct implications for embryo development, implantation and pregnancy outcomes. Historically, standard semen analysis has not included assessments of DNA integrity, creating a clear
