HHV-6B binds the sperm acrosome.

, 2013
Semen samples were pre-incubated with HHV-6B for one hr followed by incubation with either vehicle or calcium ionophore for 30 min to induce an acrosome reaction (AR).

Potentially Toxic Elements and Male Reproductive Toxicity: Mechanisms, Implications, and Protective Strategies: A Narrative Review

Journal of Biochemical and Molecular Toxicology, Volume 40, Issue 10, October 2026.
Potentially toxic elements impair male reproductive function through oxidative stress, DNA damage, mitochondrial dysfunction, inflammation, endocrine disruption and epigenetic alterations. Antioxidants, phytochemicals, chelating agents and healthy lifestyle interventions may help mitigate testicular toxicity and preserve fertility.

Global Proteomic Analysis of Sperm and Seminal Plasma From Tropically‐Adapted Rams With Contrasting Parameters of Frozen‐Thawed Semen

Molecular Reproduction and Development, Volume 93, Issue 10, October 2026.
ABSTRACT The aim of this study was to characterize the proteome of sperm and seminal plasma (SP) from rams with high semen freezability (HF) and low semen freezability (LF). Eleven ejaculates were collected from 12 rams, at 3‐day intervals, and cryopreserved (132 semen samples).

Alkalinization of Acrosome Measured by GFP as a pH Indicator and Its Relation to Sperm Capacitation [PDF]

, 2001
We previously targeted EGFP (a mutant of green fluorescent protein) to the lumen of the mouse sperm acrosome and reported the time course of EGFP release during the acrosome reaction. In the study reported here, we estimated the pH within the mouse sperm

CRISPR/Cas9‐mediated Genome‐editing Reveals 10 Testis‐enriched Genes and One Non‐testis‐enriched Gene are Dispensable for Male Fecundity in Mice

Andrology, Volume 14, Issue 7, Page 2150-2159, October 2026.
ABSTRACT Background More than 1000 genes have been identified as predominantly expressed in the human testis. Advances in gene editing technologies have enabled the rapid and efficient generation of genetically engineered mice. This approach facilitates the screening of genes essential for spermatogenesis by analyzing knockout mouse models.

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.

Evaluation of acrosomal status and sperm viability in fresh and cryopreserved specimens by the use of fluorescent peanut agglutinin lectin in conjunction with hypo-osmotic swelling test

International Brazilian Journal of Urology, 2007
OBJECTIVE: In this study, we evaluated whether the hypo-osmotic swelling test (HOST) can be used as a vital marker in combination with peanut agglutinin (PNA) - labeling in fresh and cryopreserved spermatozoa.

Seminal Plasma Exosomal miRNA Profiling Reveals hsa‐miR‐7‐5p as a Key Regulator of Sperm Motility in Asthenozoospermia

Andrology, Volume 14, Issue 7, Page 2166-2179, October 2026.
ABSTRACT Background Asthenozoospermia is a significant contributing factor to male infertility. Accumulating evidence indicates that impaired sperm motility is closely linked to dysregulated microRNA expression during spermatogenesis. Seminal plasma exosomes are enriched with diverse microRNAs, which play pivotal roles in modulating sperm motility, the

Impact of Sorting and Catch Media on Porcine Sperm Motility, Capacitation, and Viability

Andrology, Volume 14, Issue 7, Page 2207-2220, October 2026.
ABSTRACT Background Fluorescence‐activated cell sorting (FACS) has emerged as a powerful tool for selecting spermatozoa of a desired population of fluorescent biomarkers, offering potential applications in reproductive biology and agriculture. However, concerns remain regarding sorting‐induced physiological alterations that could compromise spermatozoa
