Sperm is produced in the testes within the hollow tubules called:
seminiferous tubules
Interstitial (Leydig) cells produce:
testosterone
Which hormone stimulates the Leydig cells?
lutenizing hormone / LH
The stem cells that produce sperm are called:
spermatogonia
Cells that develop in the embryo but are dormant until puberty:
spermatogonia
Where are spermatogonia located?
on the outer rim of the seminiferous tubules
When spermatogonia divide, one of the daughter cells will remain the stem cell and the other differentiates into a:
primary spermatocyte
What is the name of the cell division the spermatogonia use?
mitosis
Which type of cell in the testis is most often the source of testicular cancer?
