  1. OUTLINE GAMETOGENESIS Oogenesis stages of meiosis in the female ovarian maturation, hormones and cycles ovulation b. Spermatogenesis stages ofmeiosis in the male differentiation (spermiogenesis) FERTILIZATION Where it takes place How it takes place EARLY DEVELOPMENT

  2. SOME TERMS Gamete: egg or sperm Gametogenesis: production of eggs or sperm Oogenesis: production of eggs Spermatogenesis: production of sperm Spermiogenesis: differentiation of sperm morphology Follicle: where eggs mature in the ovary Ovulation: release of egg from follicle Polar body: nonfunctional product of meiotic divisions in oogenesis Zygote: Fertilized egg

  3. SOME MORE TERMS Oogonia: mitotically dividing cells in the ovary, will become Oocytes Primary oocyte: decision has been made to undergo meiosis, cell has grown. Cells are arrested at this stage until puberty. Secondary oocyte: has completed first meiotic division the division was unequal in terms of cytoplasm Ovum: Ovulated egg, ready to be fertilized. If fertilized, the second meitoic division will occur, another polar body will be given off.

  4. Implantation in uterine wall Fertilization through implantation
