Can Hormonal Therapy Improve the Outcomes of mTESE in Patients With Non‐Obstructive Azoospermia?

Andrology, Volume 14, Issue 6, Page 1859-1872, September 2026.
ABSTRACT Background Non‐obstructive azoospermia (NOA) represents the most severe form of male infertility. Hypogonadism is common in NOA patients, and normal testosterone (T) levels are considered essential for spermatogenesis. Fertility‐preserving hormonal therapy (FpHT) has been proposed to optimize hormonal milieu and improve sperm retrieval rates ...

The 3D genome of Gigaspora margarita unveils stable chromatin and nucleolar organization and symbiont‐dependent genome dynamics

New Phytologist, Volume 251, Issue 5, Page 2799-2817, September 2026.
Summary Arbuscular mycorrhizal fungi (AMF) are widespread plant symbionts that enhance nutrient acquisition and influence ecosystem productivity. Previous chromosome‐level assemblies of the model species Rhizophagus irregularis revealed a two‐compartment genome architecture (active A and repressed B chromatin compartments), yet its conservation across ...

The evolutionary origins of streptophyte multicellularity

New Phytologist, Volume 251, Issue 5, Page 2365-2383, September 2026.
The phylogeny of streptophytes and the deep origin of branching filamentous growth. Summary Over their more than 1 billion years of evolutionary history, streptophytes have repeatedly transitioned between unicellular, simple multicellular and complex multicellular forms.

Cross‐Species Plasticity and Divergence Under Alkaline Soil Signature Conditions Differentiating PYE From FIT Target Transcripts in the Arabidopsis thaliana Ferrome

Plant, Cell &Environment, Volume 49, Issue 9, Page 6719-6736, September 2026.
ABSTRACT Soil pH is an influential abiotic environmental factor. Here, we identify responses to central stimuli associated with calcareous alkaline soils in Arabidopsis and comparatively explore the potential of the closely related Arabidopsis halleri for addressing how plants cope with local soil pH.

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
