Review: Spermatogenesis in the bull

Animal, 2018
Spermatogenesis is a finely regulated process of germ cell multiplication and differentiation leading to the production of spermatozoa in the seminiferous tubules.

The use of deidentified organ donor testes for research

Andrology, EarlyView.
Abstract Our knowledge of testis development and function mainly comes from research using mammalian model organisms, primarily the mouse. However, there are integral differences between men and other mammalian species regarding cellular composition and expression profiles during fetal and post‐natal testis development and in the mature testis ...

Histomorphometric study of testis in deltamethrin treated albino rats

Toxicology Reports, 2014
Deltamethrin, a type II synthetic pyrethroid, has lead to a widespread concern over the potential adverse effects on human health. Adult Wistar albino rats, weighing 150–200 g, were divided into two groups of ten animals each.

The role of iron in normal and impaired testicular function

Andrology, EarlyView.
Abstract Iron plays a critical role in testicular physiology, impacting spermatogenesis, testosterone production, and overall testicular function. Iron homeostasis is maintained through systemic and cellular regulatory mechanisms, including hepcidin‐mediated systemic iron control and the iron‐responsive element/iron regulatory protein (IRE/IRP) system ...

Anti-Müllerian hormone as a diagnostic marker for testicular degeneration in dogs: insights from cryptorchid models

Frontiers in Veterinary Science
IntroductionThe increasing prevalence of infertility in male dogs in clinical practice mirrors current trends seen in human medicine. Acquired infertility is notably more common in dogs compared to congenital causes, with conditions such as testicular ...

Effect of testicular capsulotomy on lipid droplets in the seminiferous tubules of rats

, 2001
Aim: In order to reveal the histochemical alteration that might occur during the processes of the spermatogenic disruption induced by testicular capsulotomy, the location and alteration of lipid droplets in the seminiferous tubules were observed in the ...

T Cell Microenvironmental Impacts and Therapeutic Opportunities: Application to Human Testicular Germ Cell Tumors

Andrology, EarlyView.
ABSTRACT Testicular germ cell tumors (TGCT) are the leading malignancy in adolescent and young adult males, yet the immunological and cellular mechanisms governing their tumor microenvironment (TME) remain poorly understood. Here, we present a comprehensive review of TGCT pathobiology with a focus on the immune landscape, particularly the role of tumor‐

In Situ Expression of miR‐371a‐3p and miR‐373‐3p in Testicular Germ Cell Tumours and Detection in Serum

Andrology, EarlyView.
ABSTRACT Background Testicular germ cell tumours (TGCTs) are the most common type of tumour diagnosed in young men, and reliable non‐invasive biomarkers are crucial for clinical management. MicroRNAs (miRNAs) from the miR‐371–373 cluster have recently been identified as novel and more sensitive serum biomarkers than the conventional protein‐based ...

STUDY OF INTRA TESTICULAR REGULATIONS OF SPERMATOGENESIS DIFFERENTIATION BY EX-VIVO APPROACH

Journal of Fundamental and Applied Sciences, 2015
The aim of this work is to study the regulation of intratesticular during spermatogenesis ex vivo. To highlight the progress of spermatogenesis ex vivo, we developed two cell culture systems of seminiferous tubules to study the role of local factors that

Assessing a Model for a Complex Systemic Disorder—The Value of Male Mice With a Supernumerary X Chromosome for Klinefelter Syndrome Research

Andrology, EarlyView.
ABSTRACT Introduction Direct experimental investigation of Klinefelter syndrome (KS) in patients is limited because the syndrome manifests heterogeneously and affects multiple organ systems. Studying KS therefore requires a model that captures this complexity as accurately as possible while still permitting controlled experimental manipulation ...
