Abnormalities in seminiferous tubules from ALK kinase KO testes.

, 2016
(A) Histological morphology of testes stained with standard H & E. Note the irregular arrangement of germ cells at the periphery (green arrow) of the seminiferous tubule and the increased presence of vacuoles (black arrow) in ALK kinase KO mice.

Male reproductive system in stenopodidean shrimps: Unveiling basal reproductive traits in shrimp‐like Pleocyemata (Stenopodidae and Spongicolidae)

The Anatomical Record, EarlyView.
Abstract Stenopodidea represents one of the basal lineages within Pleocyemata, yet the male reproductive system (MRS) of this group remains poorly understood, with limited information available regarding its morphology and function. This study provides the first detailed description of the MRS in four stenopodidean shrimp species from two families ...

Putative second messengers affect cell coupling in the seminiferous tubules

, 1986
Junctional transfer of ions in monolayer primary cultures of Sertoli cells and in intact seminiferous tubules from 20 day-old rats has been investigated by using electrophysiological techniques.

Morphophysiological dynamics of the proximal post‐testicular ducts in Crotalus durissus Linnaeus, 1758 (Squamata: Viperidae)

The Anatomical Record, EarlyView.
Abstract The organization and function of reptilian excurrent ducts remain poorly characterized, particularly in Neotropical snakes. We provide the first integrative morphological, histochemical, immunohistochemical, and ultrastructural analysis of the proximal post‐testicular ducts of Crotalus durissus across reproductive stages.

Intercellular communication in rat seminiferous tubules

, 1983
Intercellular electrical coupling in seminiferous tubules from prepubescent and adult Wistar rats has been studied by using conventional techniques. It is found that cells in the seminiferous epithelium are electrically coupled.

Context-dependent effects of whole-body vibration on reproductive function and penile tissue integrity in sedentary male rats. [PDF]

Exp Physiol
Abstract Sedentary behaviour is increasingly recognized as a risk factor for systemic disorders; however, its effects on male reproductive health and penile tissue integrity remain insufficiently understood. Furthermore, the therapeutic role of whole‐body vibration (WBV) has not been investigated. This study evaluated the effects of sedentary behaviour

Hormonal control and signaling of the testis of the bat Molossus molossus during the processes of testicular maturation, regression, and recrudescence

The Anatomical Record, EarlyView.
Abstract Molossus molossus, a species of neotropical bat belonging to the Molossidae family, has an annual reproductive cycle that includes two peaks of spermatogenic activity, one in April and another in September, and a period of total testicular regression in December.

Effect of Antioxidants (Vitamin C and E) on Function of Testes in Albino Mice Treated With Hexavalent Chromium

Ibn Al-Haitham Journal for Pure and Applied Sciences, 2016
   Effect of antioxidants (vitamins C and E) (500mg/kg) was studied on function of testes in albino mice treated with hexavalent chromium (1000ppm). The results showed that exposure to hexavalent chromium caused a significant decrease in body weights ...

Ursolic Acid Alleviates Orchitis via Modulating Ferroptosis in Peritubular Myoid Cells of Testis

Animal Research and One Health, EarlyView.
Ursolic acid modulates key ferroptosis‐related pathways in the peritubular myoid cells of the testis in forest musk deer. ABSTRACT Chronic stress adversely affects reproductive health, increasing susceptibility to pathologies such as orchitis. Additionally, the maintenance of iron homeostasis is essential for preserving the function of the testicles ...
