The Interplay Between Trace Elements, Morphometry, and Semen Quality in Bucks During the Breeding Season

open access: yesVeterinary Medicine and Science, Volume 12, Issue 5, September 2026.
Semen, blood serum and morphometric data were collected from Honamli and Hair bucks. Semen samples were evaluated spermatologically and separated for seminal plasma collection, while blood samples obtained on the first and last collection days were processed for serum and stored at –20°C. ABSTRACT Background Breed‐related differences in spermatological

STUDIES ON THE ACROSOME. II. ACROSOME REACTION IN STARFISH SPERMATOZOA

open access: yesThe Biological Bulletin, 1954
1. When the spermatozoa of three starfish species, Asterina pectinifera, Asterias amurensis and Astropecten scoparius, are suspended in a dilute (0.1-1.0%) solution of egg albumin in sea water and mixed with homologous egg-water, three effects can be noted:a. many of the spermatozoa are agglutinated by their heads, forming permanent clusters;b.

Pelacakan Kerusakan Akrosom Spermatozoa Domba Selama Proses Pembekuan dengan Teknik Histokimia Lektin (DETECTION OF ACROSOMAL DAMAGE OF RAM SPERMATOZOA DURING FREEZING PROCESS USING LECTIN HISTHOCHEMICAL TECHNIQUE)

open access: yesJurnal Veteriner, 2016
Freezing process in ram spermatozoa caused damage of the plasma membrane and acrosome thatlead to the decrease of spermatozoa fertility. Research was conducted to evaluate acrosomal damageduring freezing process using lectin histochemical technique ...

Mito‐TEMPO Improves Post‐Thaw Quality and Fertilizing Capacity of Rooster Semen Cryopreserved in Beltsville Extender

open access: yesVeterinary Medicine and Science, Volume 12, Issue 5, September 2026.
This study reported the effect of Mito‐TEMPO on rooster semen quality cryopreserved in Beltsville extender. Semen diluted in extenders containing 10 or 100 µM of Mito‐TEMPO presented higher motility, average path velocity as well as membrane/acrosome integrity, mitochondrial activity, and fertility rate; and lower lipid peroxidation, apoptosis rate ...

Beyond Postmortem Interval Estimation: The Use of Insects for the Investigation of Fatal Sexual Assaults

open access: yesWIREs Forensic Science, Volume 8, Issue 3, September 2026.
Sperm cells/heads from within the crop of a third instar larva. ABSTRACT Sexual assaults including unwanted sexual touching and rape are continuously occurring within England and Wales, despite police intervention. Furthermore, as seen within recent media reports, these types of offenses can occur immediately prior to homicide.

Testicular SIRT1 Loss Reveals an Aging‐Like Proteomic Landscape and Precipitates Reproductive Deterioration

open access: yesAndrology, Volume 14, Issue 6, Page 1579-1589, September 2026.
ABSTRACT Background Advanced paternal age is associated with reduced male fertility and testicular dysfunction. Among the molecular regulators involved in aging, SIRT1, a NAD+‐dependent deacetylase, plays a pivotal role in maintaining oxidative balance and cellular homeostasis.

Testis‐Enriched F‐Box Protein FBXO39 Is Important for Spermiogenesis and Male Fertility in Mice

open access: yesAndrology, Volume 14, Issue 6, Page 1636-1646, September 2026.
ABSTRACT Background The SCF (Skp–Cullin–F‐box) complex is a major class of E3 ubiquitin ligases. F‐box proteins constitute the SCF complex and play a critical role in recognizing substrates for ubiquitination. In mice, several F‐box proteins, including FBXO36 and FBXO39, are predominantly expressed in testes.

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

open access: yesVeterinary 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

open access: yesInternational 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.

Improvement of Mouse Spermatozoa Freezing at −80°C With Ascorbic Acid 2‐Glucoside at Thawing Phase

open access: yesAndrology, Volume 14, Issue 6, Page 1647-1655, September 2026.
ABSTRACT Background Sperm cryopreservation is the most common method to maintain a great number of mutant mouse lines. However, the use of liquid nitrogen (LN2) for freezing presents considerable problems in terms of cost, safety, and accessibility. For this reason, the storage of semen samples at ‐80° in ultra‐freezers has been increasingly used in ...
