Reproductive and Development
Male
Spermatogenesis
64 days to produce mature sperm
Spermatognia(stem cell)
Mitosis (two daughter cells)
Meiosis I
Primary spermatocyte
one daughter cell divides into two (haploid)
Meiosis II
Secondary Spermatocyte
two daughter haploid divide into four
Spermatid
spermatozoa
Pathway
Epididymis
take twelve days to pass through
Vas Deferens
Testes,
Ampulla ducts deferens
Ejaculatory duct
Fructose added from Seminal vesicle
Prostate Ureatha
prostate coagulate added
