Short-term perfluorooctane sulfonate exposure impairs Leydig cell regeneration in the adult rat testis via targeting hedgehog signaling

open access: yesEcotoxicology and Environmental Safety, 2021
Perfluorooctane sulfonate is related to male reproductive dysfunction in rats and humans. However, the underlying mechanism remains unknown. Here, we reported the effects of short-term exposure to perfluorooctane sulfonate on the regeneration of Leydig ...

Leydig cells express neural cell adhesion molecules in vivo and in vitro [PDF]

open access: yes, 1992
The neural cell adhesion molecule (NCAM) polypeptides are expressed by numerous tissues during embryonic development, where they are involved in cell-cell interactions.

A Novel Model Using AAV9-Cre to Knockout Adult Leydig Cell Gene Expression Reveals a Physiological Role of Glucocorticoid Receptor Signalling in Leydig Cell Function

open access: yes, 2022
Glucocorticoids are steroids involved in key physiological processes such as development, metabolism, inflammatory and stress responses and are mostly used exogenously as medications to treat various inflammation-based conditions.

Use of novel serum markers in clinical follow-up of Sertoli-Leydig cell turnours [PDF]

open access: yes, 2007
Background: Sertoli-Leyclig cell tumours of the ovary account for only 0.2% of malignant ovarian tumours. Two-thirds of all patients become apparent due to the tumour's hormone production. Methods: A 41-year-old patient (gravida 4, para 4) presented with

Aldosterone Blocks Rat Stem Leydig Cell Development In Vitro

open access: yesFrontiers in Endocrinology, 2018
Aldosterone (ALDO) is a primary endogenous mineralocorticoid, appearing as the main hormone controlling sodium and water homeostasis. Its emerging role in the development of many organs has gained interest over the past few years.

Transcriptional Profiling of Luteinizing Hormone Receptor-Deficient Mice Before and after Testosterone Treatment Provides Insight into the Hormonal Control of Postnatal Testicular Development and Leydig Cell Differentiation [PDF]

open access: yes, 2010
Luteinizing hormone (LH) is a key regulator of male fertility through its effects on testosterone secretion by Leydig cells. Transcriptional control of this is, however, currently poorly understood.

Dibutyltin Dichloride Retards Leydig Cell Developmental Regeneration in Adult Rat Testis

open access: yesFrontiers in Pharmacology, 2018
Dibutyltin dichloride (DBTCl), widely used as plastic stabilizer, can cause comprehensive toxicity. The present study aims to investigate the effects of DBTCl on rat Leydig cell developmental regeneration and characterize the related mechanism.

Bilateral Leydig Cell Tumor in a Capuchin Monkey (Sapajus apella): Case Report. [PDF]

open access: yesJ Med Primatol
ABSTRACT Leydig cell tumors (LCTs) are uncommon in nonhuman primates (NHPs). A bilateral LCT was identified in a 20‐year‐old male capuchin monkey (Sapajus apella) maintained under human care. Ultrasonography revealed a right testicular nodule, while necropsy identified bilateral testicular masses. Histopathology confirmed bilateral LCT.

Testicular development in mice lacking receptors for follicle stimulating hormone and androgen [PDF]

open access: yes, 2012
Post-natal testicular development is dependent on gonadotrophin and androgen stimulation. Follicle stimulating hormone (FSH) acts through receptors (FSHR) on the Sertoli cell to stimulate spermatogenesis while androgens promote testis growth through ...

Leydig cell tumor and hyperplasia : a review

open access: yesAnalytical and quantitative cytology and histology, 2007
We describe the role of Leydig cells in normal, hyperplastic and neoplastic testis. Recent acquisitions on etiology and pathobiology of Leydig cell proliferations, unusual microscopic presentations and clinical and morphologic features predictive of ...
