Histological changes in the testicle of a calico cat

Veterinary Record Case Reports, Volume 14, Issue 1, February 2026.
Abstract A cat that presents orange and black colours (tortoiseshell), or all three colours (calico), is expected to be female since orange and black are colours related to the X chromosome, and white to the autosomal chromosomes. This study reported the case of an entire male calico cat.

The absence of both RIBC1 and RIBC2 induces decreased sperm motility and litter size in male mice

Andrology, Volume 14, Issue 2, Page 545-554, February 2026.
Abstract Background RIBC1 (RIB43A domain with coiled‐coils 1) and RIBC2 (RIB43A domain with coiled‐coils 2) are homolog proteins of RIB43a which is localized to microtubules in the cilia and flagella of unicellular organisms. Cryo‐electron microscopy and artificial intelligence studies showed that RIBC1 and RIBC2 are microtubule inner proteins (MIPs ...

Gonadal function in males with WFS1 spectrum disorder (Wolfram syndrome)—A European cohort perspective

Andrology, Volume 14, Issue 2, Page 398-410, February 2026.
Abstract Background WFS1 spectrum disorder, also known as Wolfram syndrome (WS) is an ultra‐rare (<1:500,000; ORPHA: 3463) monogenic (OMIM #222300) progressive neuroendocrine and neurodegenerative disorder, characterised by early‐onset insulin‐dependent diabetes, optic atrophy, central diabetes insipidus and sensi‐neuronal deafness.

Comparative efficacy of varicocelectomy and intrauterine insemination in varicocoele patients with mild semen abnormalities: An observational study

Andrology, Volume 14, Issue 2, Page 487-495, February 2026.
Abstract Background Varicocoele is a common cause of male infertility, affecting spermatogenesis through increased testicular temperature, venous stasis, and oxidative stress. Microsurgical subinguinal varicocelectomy improves semen quality, whereas intrauterine insemination is widely used for mild male factor infertility.
