Proteomic analysis of the zone of degeneration at the mitosis–meiosis transition stage in wild‐caught male catshark (Scyliorhinus canicula), correlated with an unusually high‐water temperature in the English Channel

open access: yesJournal of Fish Biology, EarlyView.
Abstract In the context of current global change, variations in water temperature are one of the environmental conditions with serious consequences for marine life, including reproductive processes. In the small spotted catshark Scyliorhinus canicula, spermatogenesis occurs in spermatocysts composed of synchronously developing germ cells associated ...

ClC‐2 Contributes to Hypotonicity‐Induced Adrenal Aldosterone Secretion

open access: yesActa Physiologica, Volume 242, Issue 3, March 2026.
ABSTRACT Aim The zona glomerulosa (ZG) of the adrenal cortex regulates blood pressure and electrolyte homeostasis through aldosterone production. In ZG cells, potassium and angiotensin II (Ang II) trigger calcium oscillations that drive aldosterone synthesis.

[Sertoli cell secretion].

open access: yesLijecnicki vjesnik, 1991
The article deals with the secretion of Sertoli cells. Different substances they secrete and their role in the testis are described. These cells release a number of factors in their environment, thus creating a local "milieu" and exerting a local control of spermatogenesis in the seminiferous tubules.

Subchronic Exposure to Aripiprazole Subtly Impacts on Rodents' Sperm Quality and Fertility

open access: yesBasic &Clinical Pharmacology &Toxicology, Volume 138, Issue 3, March 2026.
ABSTRACT Aripiprazole, a third‐generation antidepressant/antipsychotic drug, acts on serotonergic and dopaminergic receptors and is widely prescribed for mental disorders, such as depression and schizophrenia. Studies indicate that this class of drugs can impact directly on sperm quality and fertility.

Spermatogenesis and sperm structure in the black-striped pipefish Syngnathus abaster (Teleostei, Syngnathidae) = Spermatogenesi e struttura degli spermatozoi in Syngnathus abaster (Teleostei, Synghathidae) [PDF]

open access: yes, 2010
The gonads of adult males of the black-striped pipejish Syngnathus abaster were observed during the reproductive season to describe mature sperm both quantitativel/y and qualitatively.

The effect of salubrinal on the endoplasmic reticulum stress pathway in heat‐stressed spermatogonial cells in vitro

open access: yesFEBS Open Bio, Volume 16, Issue 2, Page 340-351, February 2026.
This study investigates the protective role of salubrinal against heat‐induced endoplasmic reticulum (ER) stress in mouse spermatogenic cells (GC1 and GC2). By modulating the ER stress pathway, salubrinal alleviates cellular stress and supports spermatogenic cell survival, suggesting its potential as a therapeutic candidate for heat‐related infertility.
