Diagram of stages of embryo development to a larval and adult stage.

Embryonic development starts with the fertilization of an egg cell (ovum) by a sperm cell (spermatozoon). [1]
An ovarian follicle is a roughly spheroid cellular aggregation set found in the ovaries.It secretes hormones that influence stages of the menstrual cycle.In humans, women have approximately 200,000 to 300,000 follicles at the time of puberty, [1] [2] each with the potential to release an egg cell (ovum) at ovulation for fertilization.
