What are the different cell stages in spermatogenesis
spermatogonium –> primary spermatocyte –> secondary spermatocyte –> early spermatid (round spermatid) –> later spermatid (elongating spermatid)
name it

Why is the blood-testis barrier so important?
As spermatogonium mature, they can no longer come in contact with the immune system, as they will be recognized as a foreign invader. Therefore, the blood-testis barrier acts as a protective barrier for the developing spermatogonium
name it

What hormone acts on sertoli cells? What hormone acts on leydig cells?
FSH –> Sertoli cells
LH –> leydig cells
Name it. Why does it look so fatty/oily?

Leydig cells
It looks fatty/oily because it secretes testosterone, which is a lipid soluble hormone.
