Polystyrene microplastics impaired the function of leydig cells via GRP78/PERK/CHOP mediated endoplasmic reticulum stress in vivo and in vitro

open access: yesEcotoxicology and Environmental Safety
The toxic effect of Polystyrene Microplastics (PS-MPs) on leydig cells were found in male mice, but the toxic mechanism was not clear. The PS-MPs exposure mice model and cell model were established in this study to explore the leydig cells toxic ...

Gonadal Development in Larvae of the Paedomorphic Ambystoma mexicanum (Amphibia: Urodela)

open access: yesJournal of Morphology, Volume 287, Issue 3, March 2026.
This research analyzes the gonads of Ambystoma mexicanum larvae of both sexes, revealing significant changes such as the onset of vitellogenesis in females at 9 months of age and oocytes with signs of maturity at 12 months. In males, gonadal maturity occurs earlier, with a notable cephalocaudal and lateromedial testicular regionalization, and ...

Immunostaining of P450c17, Aromatase and Oestrogen Receptor Alpha in Germ and Somatic Cells During Gonadal Development in Greater Rhea

open access: yesAnatomia, Histologia, Embryologia, Volume 55, Issue 2, March 2026.
ABSTRACT The greater rhea (Rhea americana), the largest bird species in South America, has significant economic value due to its meat, eggs, leather, feathers and oil. However, its lack of external sexual dimorphism poses challenges for reproductive management and breeding programmes.

Linking Canine Teeth Eruption, Testicular Histology and Testosterone Levels as Indicators of Pubertal Maturation in Male Dogs

open access: yesAnatomia, Histologia, Embryologia, Volume 55, Issue 2, March 2026.
ABSTRACT Puberty in male dogs marks the transition to sexual maturity, characterised by rising testosterone and testicular maturation. While often estimated at 6 months, the absence of birth records frequently complicates age determination. This study evaluated whether permanent canine tooth eruption serves as a reliable, complementary marker for ...

Modified cytoskeletal and extracellular matrix composition in the canine testis after long‐acting gonadotropin‐releasing hormone agonist deslorelin treatment

open access: yesAndrology, Volume 14, Issue 3, Page 718-735, March 2026.
Abstract Background Long‐acting gonadotropin‐releasing hormone (GnRH) agonists are commonly used for fertility control in male dogs. Their effect on testicular histomorphology has not been clarified. Objectives To elucidate the mechanisms underlying androgen withdrawal in response to long‐acting GnRH agonist deslorelin 4.7 mg treatment on testicular ...
