Chaque tubule séminifère est bordée de cellules nourricières spermatozoïdes (cellules de Sertoli) et de cellules souches de spermatozoïdes (spermatogonies).

Each seminiferous tubule is lined with sperm nurse cells (Sertoli cells) and sperm stem cells (Spermatagonia).

Avec la survenue de la puberté, spermatogonia au sous-sol membrane tubule séminifère proliférer par de la mitose et prophase divisions et génèrent-elles ces haploïdes SPERMATOCYTES.

With the onset of puberty, spermatogonia at the basement membrane of the seminiferous tubule proliferate by mitotic then meiotic divisions and give rise to the haploid SPERMATOCYTES.
