Diagnostic yield of OCT3/4 reflex testing in testicular biopsy

Histopathology, Volume 89, Issue 1, Page 136-143, July 2026.
GCNIS detection frequency was 48/3353 (1.4%) testicular biopsies from 42/1870 (2.2%) men who underwent testicular biopsy with or without testicular sperm extraction (TESE). OCT3/4 was particularly helpful for detecting interstitial seminoma, GCNIS coexisting with mature spermatogenesis, and focal GCNIS.

Radiographic Assessment of Bone Maturation: A Tool to Estimate Sexual Maturity in Common Dolphins (Delphinus delphis)?

Marine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT Accurate inference of sexual maturity is fundamental to interpreting marine mammal life histories and population structure. Using Bayesian logistic regression models with a hierarchical ordinal (HOF‐style) parameterisation and canonical analysis of principal coordinates (CAP), we evaluate skeletal metrics in the pectoral flippers of common ...

Gonadal Histology and Spawning Season of Otolithoides pama in the Thanlwin River Estuary

Aquaculture, Fish and Fisheries, Volume 6, Issue 3, June 2026.
ABSTRACT The spawning season of Otolithoides pama in the Thanlwin estuary was estimated through gonadosomatic index (GSI) and histological analyses of gonadal development. A total of 290 specimens (240 females and 50 males) were collected monthly from 5 sites—Ahlat, Kyauk Tan, Daye, Nyaung Pin Seik and Tarana—between January and December 2024.

Sex Determination in Sponges

Molecular Reproduction and Development, Volume 93, Issue 6, June 2026.
ABSTRACT Sex determination in Porifera remains one of the least understood aspects of early metazoan biology despite the group's key phylogenetic position. Sponges display exceptional diversity in sexual systems—ranging from stable gonochorism to sequential hermaphroditism and sex reversal—yet lack morphological dimorphism and any discrete gonadal ...

SOX30 Governs Synaptonemal Complex Assembly and Homologous Recombination in Male Meiosis

Cell Proliferation, Volume 59, Issue 6, June 2026.
The transcription factor SOX30 directly binds promoter regions of SYCE1 and SYCE2 to mediate their transcriptional activation, thereby enabling proper assembly of central elements within the synaptonemal complex. Structural destabilisation of the synaptonemal complex in Sox30 KK spermatocytes triggers synaptic discontinuity, impairs homologous ...

Deletion of Mgat2 in spermatogonia blocks spermatogenesis

Frontiers in Cell and Developmental Biology
Identifying factors required for spermatogenesis is important for understanding mechanisms of male fertility. Inactivation of either the Mgat1 or Man2a2 gene leads to a block in spermatogenesis causing infertility in male mice. MGAT1 GlcNAc-transferase initiates complex N-glycan synthesis and MAN2A2 mannosidase generates the substrate for MGAT2 GlcNAc ...

Advances in Visualizing Cytosine Methylation and Allele‐Specific Epigenetic States in Tissue Context

Pathology International, Volume 76, Issue 6, June 2026.
The ICON method enables sequence‐specific, bisulfite‐free visualization of DNA methylation through chemical recognition of methylated cytosines. Following probe hybridization under mild denaturing conditions, methylation‐dependent interstrand complexes are stabilized by covalent crosslinking.
