Contraction of the cremaster muscle is responsible for pulling testes up.
initial division occurs in seminiferous tubules
spermatogonium > spermatocyte > spermatid > spermatozoan/sperm
mature sperm = 60um
seminiferous tubules > rete testes > epididymis (stored ~6 weeks) > vas

2 sac structures above the prostate. Produce 60% of seminal fluid, other 40%
is prostate. Empty fluid into ejaculatory duct to combine with sperm
