Menopause is a natural event in a woman’s life when the ovaries are depleted of eggs and she has not menstruated for 12 consecutive months. Treatment for symptoms may or may not be necessary depending on their severity.
Infertility is defined as not being able to get pregnant despite having regular sexual intercourse for at least 12 months (six months if the woman is older than 35). About 10-15 percent of couples in the United States experience infertility.
A woman’s period, or menstruation, is when the lining of the womb sheds, along with blood, exiting through the vagina. This happens if egg fertilization does not occur. Menstruation usually lasts 3-5 days.
