Chromosome‐Level Genomics and Historical Museum Collections Reveal New Insights Into the Population Structure and Chromosome Evolution of Waterbuck

Molecular Ecology, Volume 35, Issue 1, January 2026.
ABSTRACT Advances in sequencing and chromosome‐scale assembly have brought non‐model animals into focus, deepening our understanding of genome and chromosome evolution. Here, we present the waterbuck (Kobus ellipsiprymnus) as an emerging model antelope for studying population dynamics and chromosome evolution.

Effect of Tadalafil on Testicular Histology and Sperm Parameters in An Experimental Varicocele Model

Andrologia, Volume 2026, Issue 1, 2026.
Objectives Varicocele is a common cause of male infertility, often associated with oxidative stress and impaired testicular blood flow. This study aimed to evaluate whether orally administered tadalafil, through its cGMP‐mediated vasodilatory and antioxidant effects, can protect against histological damage and altered sperm parameters in a rat model of

Seminal Extracellular Vesicles LGALS3BP as a Potential Biomarker of Varicocele‐Associated Infertility in TMT‐Based Quantitative Proteomic Analysis

Andrologia, Volume 2026, Issue 1, 2026.
The proteomic analysis of seminal plasma (SP) is a powerful tool for screening and identifying potential novel biomarkers of male infertility. However, the proteomic composition of seminal extracellular (SE) vesicles in varicocele (VC) is still poorly characterized.

Effects of Prawn Shell Meal Diets on Hemocyte Count, Hemolymph Clotting, and Sperm Quality of the Freshwater Prawn Macrobrachium caementarius

Aquaculture Research, Volume 2026, Issue 1, 2026.
Crustacean shells are composed of chitin, which is bound to protein and minerals, along with other essential nutrients. These components are necessary for growth, immune response, the formation of reproductive structures, and the enhancement of sperm quality.
