first, male gamete develop and matured in the testis (of cos for man) (1)
spermatogenesis  occur in the semineferous tubule
primordial germinal cell develops into spermatogonia
after that.......................................................................................................................................................... ( oh my god,,my memory got loss)

ok got it!!
each spermatogonia undergo mitosis to produce 2 daughter cells
one daughter cell remain as spermatogonium n the other one  bcomes primary spermatocyte and then .......................................................................................................(shit! i forgot it. scond time)
ok the primary spermatocyte undergoes meiosis 1 to produce 2 secondary haploid spermatocytes
secondary spermatocytes undergo meiosisII  to produce spermatids.
spermatids get nourishment from sertoli cell
and undergo differentiation flagella and acrosome appear
finally become sperm tattararraraara...
