In males, the N-terminal region and the LRR1-LRR7 repeats are essential for the high affinity binding of human CG (hCG), which stimulates the production of testosterone and maturation of fetal Leydig
cells during early embryogenesis.
The values of primary testis volume, absolute Cavalieri testis volume, the volume of seminiferous tubule epithelium and lumen, the significant increase (P=0.008) in the total number of Leydig
cells compared to the control group.
Finally, the adventitia consists of vascular loose fibrous connective tissue that contains many nerve plexuses and Leydig
Furthermore, a severe decrease in interstitial space and severe atrophy of Leydig
cells was observed.
Role of Brain-Derived Neurotrophic Factor (BDNF) and its receptor TrkB in reproductive system in developing rats: possible role for Leydig
cell and germ cell development.
Affected fetuses possess fully functioning Leydig
and Sertoli cells, but they cannot convert testosterone to DHT and thus present with variable degrees of undermasculinized external genitalia.
Based on evidence showing the interaction between these systems in different cells, the aim of the present work was to study the relationship between the actions of NO and ATP-evoked purinergic currents in mice Leydig
cells with the whole cell patch clamp technique.
Especially, the administration of ND in male often accomplishes impaired spermatogenesis, depletion of Leydig
cells, and germ cell sloughing in the testis , atrophic change of prostate , and reduction of fertility .
Variation in the circumtesticular Leydig
cell tunic of teiid lizards (Cnemidophorus and Ameiva).
Other ovarian tumors include steroid cell tumor, ovarian luteoma, and Leydig
cell origin of testicular carcinoid tumour: immunohistochemical and electron microscopic evidence," Histopathology, vol.
Microscopically, an SLCT will have varying proportions of both Sertoli and Leydig
