The formation of a quality egg is the result of a bitter child screened by low levels of FSH, growing up and maturing after experiencing the environmental hardship of low levels of FSH, and playing to its strengths by secreting more estrogen and inhibitory hormones, controlling the central pituitary gland, inhibiting the secretion of FSH, and achieving the process of dominance by self-interest in addition to others.

As the saying goes, suffering its heart and mind, laboring its body and soul, before descending to the great task with the people.
