Describe oogenesis | production of female gametes within ovary |

State the function of primordial follicles | contain primary oocytes |
State the function of mature follicles | contain secondary oocytes |
State the function of secondary oocyte | if ovulated, develops into corpus luteum |
Outline the process of oogenesis | -oogonia begin meiosis forming primary oocytes -in puberty, FSH causes primary oocytes to mature monthly -ovulation occurs, secondary oocyte in fallopian tube -if fertilized, meiosis is completed producing ovum |
Compare spermatogenesis and oogenesis | both create haploid gametes and involve mitosis and meiosis, spermatogenesis begins in puberty while oogenesis begins during fetal development, sperm are continually made while ova are made monthly |
