The cycle includes two interrelated processes: oogenesis (the production of female gametes) and folliculogenesis (the growth and development of ovarian follicles).

The menstrual cycle begins with the maturation of oocytes through the process of oogenesis, as well as concurrent follicle development that stimulates ovulation.

Oogenesis differs from spermatogenesis primarily in its outcomes and timing. While spermatogenesis results in four viable sperm cells from one germ cell, oogenesis yields one …
