Menopause accelerates deaths from heart disease, and these can be prevented by hormone replacement therapy

While egg death continue unabated, the speed with which eggs dye is reduced somewhat after birth such that at the time of the first period the girl child has only three hundred thousand to five hundred thousand eggs left. It is at this time during a female’s development that her ovaries begin to recruit some of the dying eggs for ovulation.

This period of egg recruitment marks the reproductive phase in the female, a period in which she will recruit and ovulate about 420 eggs. This recruitment of eggs is accompanied by a 40 year period in which the female body is bathed with female hormones, chief of which is oestrogen.
