| 11. | Osteocalcin acts on Leydig cells of the testis to stimulate testosterone biosynthesis and therefore affect male fertility.
|
| 12. | Immunohistochemical markers of Leydig cell tumours include inhibin-alpha, calretinin, and melan-A.
|
| 13. | LH stimulates the Leydig cells of the testes to make testosterone and blood levels begin to rise.
|
| 14. | Leydig cells will work for testosterone production if " transplanted " into castrated male mice.
|
| 15. | CB 1 is present on Leydig cells and human ovaries, oviducts myometrium, decidua, and placenta.
|
| 16. | Sections of testicular tissue from rat revealed positive immunoreactivity against anti-inhibin intensely appeared in Leydig cells.
|
| 17. | However, a faint positive reaction was detected in Leydig cell cytoplasm in rats treated with anise oil.
|
| 18. | The testes have two primary functions : to produce hormones and to produce Sertoli and Leydig cells ).
|
| 19. | Leydig cells are located in the testis and known for the function as a support cell in spermatogenesis.
|
| 20. | Testicular cancer, Leydig cell tumours and Sertoli cell tumours are also associated with reduced sperm count and quality.
