| 11. | In mammals it occurs in the seminiferous tubules of the male testes in a stepwise fashion.
|
| 12. | Through this hormonal disruption, the process of sperm production in the seminiferous tubules is reduced.
|
| 13. | It is secreted from the Sertoli cells, located in the seminiferous tubules inside the testes.
|
| 14. | During the transabdominal stage ( 8 to 15 weeks of gestation ), the seminiferous cords.
|
| 15. | In the male, the germ cells colonise the seminiferous cords of the medulla, becoming spermatogonia.
|
| 16. | This absorption creates a fluid current that moves the immobile sperm from the seminiferous tubules to the epididymis.
|
| 17. | The higher levels of these hormones enable spermatogenesis in the seminiferous tubules and sperm maturation in the epididymis.
|
| 18. | This is overcome at puberty when cells within seminiferous tubules called Sertoli cells start making their own retinoic acid.
|
| 19. | Each lobule contains the seminiferous tubules, extending from the base where they end blindly, towards the apex.
|
| 20. | I believe the seminiferous ducts in the testicles can rupture, causing sharp pain, but no permanent damage.
