puberty
What things happen during spermatid maturation?
the development of a flagellum. The nucleus moves to the head of the spermatid. An acrosomal cap covers the tip
Which cells secrete FSH?
Sertoli cells and spermatogonia
What is the fxn of FSH?
Stimulates primary spermoatocytes to undergo meiosis
Where does testosterone come from?

What happens to serum testosterone at 3-6 months old?

Why does testosterone levels rise at 3-6mo old?
It’s thought to push the male development process
At puberty, what causes testosterone to be released from Leydig cells?
LH
Testosterone production is pretty constant up until which decade of life?
