Relationship between sperm progressive motility and DNA integrity in fertile and infertile men

Middle East Fertility Society Journal, 2018
Background: Progressive sperm motility was found to be predictive for in vitro and in vivo fertilization. There has been an increase in the literature of studies investigating whether DNA fragmentation could be associated with other semen parameters ...

Mapping the Non‐Canonical Splicing Variants: Decrypting the Hidden Genetic Architecture of Idiopathic Male Infertility

Advanced Science, EarlyView.
This study highlights the significance of non‐canonical splicing variants in male infertility, a factor often overlooked during the analysis of high‐throughput sequencing data. Incorporating the non‐canonical splicing variants prioritization in the genetic analysis pipeline will increase the genetic diagnosis of patients with male infertility ...

Effects of Diethylstilbestrol Administration on Sperm Motility and Reproductive Function in Male Japanese Quail (Coturnix japonica)

The Journal of Poultry Science, 2002
The present study was undertaken to evaluating the effects of diethylstilbestrol (DES) on sperm motility and reproductive function in male Japanese quail. To do so, we have identified the method that ensures maximal quail sperm motility, i.e.

Low Sperm Motility Is Determined by Abnormal Protein Modification during Epididymal Maturation

The World Journal of Men's Health, 2022
Purpose:Purpose: During epididymal sperm maturation, spermatozoa acquire progressive motility through dynamic protein modifica-tions. However, the relationship between sequential protein modifications during epididymal sperm maturation and sperm motility

EIF5A Couples Translational Control With Transcriptional Reprogramming Through Chromocenter Reorganization During Spermiogenesis

Advanced Science, EarlyView.
The translation factor Eukaryotic translation initiation factor 5A (eIF5A) is essential for male fertility in mice. It supports the translation of proteins crucial for heterochromatin organization and acrosome formation. eIF5A deficiency disrupts chromocenter integrity, increases chromatin accessibility, and causes transcriptional dysregulation ...

Quercetin Protects Goat Sperm Motility by Inhibiting Neutrophil Extracellular Traps and Maintaining Plasma Membrane and Acrosome Integrity

Veterinary Sciences
Enhancing or protecting sperm motility has always been a pivotal approach to improving the ewe pregnancy rate. Sperm motility is highly susceptible to the immune status of the reproductive tract.

Activation of Ciona sperm motility: phosphorylation of dynein polypeptides and effects of a tyrosine kinase inhibitor [PDF]

, 1991
A high molecular mass dynein ATPase polypeptide and a 18–20 kDa dynein light chain of Ciona sperm flagella are phosphorylated during in vivo activation of motility or in vitro activation of motility by incubation with cyclic AMP.

pH-dependent effects of procaine on equine gamete activation [PDF]

, 2019
Procaine directly triggers pH-dependent cytokinesis in equine oocytes and induces hypermotility in stallion spermatozoa, an important event during capacitation. However, procaine-induced hyperactivated motility is abolished when sperm is washed to remove

CD147/Basigin: From Integrative Molecular Hub to Translational Therapeutic Target

Advanced Science, EarlyView.
This review conceptualizes CD147 as a fundamental “Energy‐Structure Coupler,” physically bridging metabolic flux (via MCTs) with morphogenetic plasticity (via integrins/MMPs) to drive cancer, infection, and autoimmunity. Addressing the “specificity paradox” that limits current translation, the authors chart a strategic roadmap—spanning logic‐gated ...
