Computer‐Assisted Sperm Analysis (CASA) Versus Manual Evaluation and the Clinical Significance of Sperm Hyperactivated Motility

Andrology, Volume 14, Issue 5, Page 1401-1412, July 2026.
ABSTRACT Background Semen analysis remains the first‐line diagnostic test for male infertility, although it is affected by operator subjectivity. Computer‐assisted sperm analysis (CASA) is proposed to improve objectivity; however, its accuracy and clinical relevance remain uncertain.

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.
