The Therapeutic Effects of Crocus sativus L. and Its Constituents on the Improving Treatment of Azoospermia: A Narrative Review

Health Science Reports, Volume 9, Issue 9, September 2026.
ABSTRACT Background and Aims Azoospermia, defined as the complete absence of sperm in the ejaculate, is a major cause of male infertility and is classified into obstructive and non‐obstructive forms. While obstructive azoospermia is primarily mechanical in origin, non‐obstructive azoospermia (NOA) is characterized by impaired spermatogenesis and is ...

Dose‐Dependent Effects of Clinoptilolite Supplementation on Sperm Quality and Oxidative Stress During Canine Semen Cryopreservation

Veterinary Medicine and Science, Volume 12, Issue 5, September 2026.
Clinoptilolite supplementation in canine semen extenders showed dose‐dependent effects during cryopreservation, with 2% yielding optimal post‐thaw sperm quality. Higher concentrations impaired sperm parameters, likely due to oxidative imbalance, highlighting the importance of precise dosing to enhance cryosurvival.

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

Andrology, 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

Andrology, 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.

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

Andrology, 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 ...

Fish Sperm Subpopulations Detection, Separation, and Application: Current State and Trends

Reviews in Aquaculture, Volume 18, Issue 4, September 2026.
Modern advances in sperm biology highlight the necessity of recognising intra‐ejaculate heterogeneity as a central concept for advancing both the fundamental understanding of fertilisation processes and the development of artificial reproduction techniques in fishes. ABSTRACT Sperm subpopulations represent a fundamental manifestation of intra‐ejaculate

Combined Effects of Algae‐Supplemented Feeding Regimes and Water Temperature on Sperm Quality of Common Carp (Cyprinus carpio) Broodstock During Spawning

Aquaculture, Fish and Fisheries, Volume 6, Issue 4, August 2026.
ABSTRACT This exploratory study investigated associations between dietary algae supplementation (1% and 3%) and sperm quality in male common carp (Cyprinus carpio) broodstock during two consecutive spawning seasons under commercial farming conditions. Sperm quality was evaluated using conventional motility and kinetic parameters together with analyses ...

Industrial Hydrocarbons Exposure Deteriorates Sperm Integrity and Reproductive Function

Journal of Biochemical and Molecular Toxicology, Volume 40, Issue 8, August 2026.
ABSTRACT Occupational exposure to polycyclic aromatic hydrocarbons (PAHs) or metal fumes in the workplace may be detrimental to male fertility. The present study compared sperm concentration, total motility, strict morphology and oxidative stress and SDF levels between 81 men, controls (n = 17) and workers from plastic industry workers (n = 18), steel ...

Epididymosome‐Supplemented Extender Induces Changes in Morpho‐Functional Traits and microRNA Levels of Post‐Thaw Sperm and Improves Embryo Developmental Potential

Molecular Reproduction and Development, Volume 93, Issue 8, August 2026.
ABSTRACT While molecular signature contributes to sperm quality and fertility potential, sperm may lost key molecules during cryopreservation. Since sperm cells are transcriptionally inert and rely on interactions with epididymosomes (epEVs) to acquire molecules, herein, we investigated the effects of the addition of epEVs to the cryopreservation ...
