Biallelic inactivation of the LHCGR causes Leydig cell hypoplasia (LCH, OMIM#238320) that leads to male disorders of sexual differentiation (DSD).
Ameliorative effects of curcumin on the structural parameters of seminiferous tubules and Leydig cells in metronidazole-treated mice: a stereological approach.
The submucosa is similar to the small intestine, composed of loose fibrous connective tissue containing many hemolymphatic vessels and Leydig cells and superficial aggregations of hemocytes.
In this study, we demonstrated that purinergic and nitrergic systems interact in mice Leydig cells. Our results show that the purinergic current amplitudes were not directly modulated by NO produced in basal conditions but that activation of NOS with L-arginine modified the ATP-induced current.
The Leydig cells (arrows) were strongly immune-stained for StAR.

Furthermore, leptin treatment of adult ob/ob males corrects their sterility, an effect that is mediated at least partly by a normalization in testicular weight, spermatogenesis, and Leydig cells morphology [42].
The authors of this study conclude that a hypogonadal state or Leydig cell failure can be induced with zinc deficiency altering testicular steroidogenesis.
To ensure that inherent toxicity of our tested chemicals and their mixtures did not induce a downturn in testosterone synthesis, thereby confounding any genuine anti-androgenic effects, we assessed the functional integrity of the testosterone-producing Leydig cell population by immunolabeling of cytochrome P450 (CYP11A1), a key enzyme of the androgen biosynthesis pathway.
The researchers reasoned that the direct conversion of adult skin cells into Leydig cells would be a faster, safer regenerative medicine approach.

TABLE 1: Serum testosterone level and the number of Leydig cells were determined in the intact, diabetic-saline (Dia-Sa), diabetic-insulin (Dia-Ins), diabetic-omega3 (Dia-omg3), and diabetic-insulin-omega3 (Dia-Ins-omg3) groups, 35 days after the onset of DM.
