Menopause is the point in time when a woman's menstrual periods stop. Menopause happens because the ovaries stop producing the hormones estrogen and progesterone. Once you have gone through menopause, you can't get pregnant anymore.our doctor also could test the amount of hormones in your blood. But because hormones change during your menstrual cycle, these tests alone can't tell for sure that you have gone through menopause or are getting close to it. Unless there is a medical reason to test, doctors usually don't recommend it.
Ovulation is also arrested in some women during the first 5-6 months of active breastfeeding, leading to a larger stock of follicles at around the age of 45 years. So, pregnancy and breastfeeding are likely to delay the onset of the age of menopause.For example, let us assume that a daughter and her mother started menstruating when both of them were 12 years old.aking birth control pills which prevent ovulation will also delay menopause. Birth control pills contain hormones that can block the process of oocyte maturation and ovulation. This will again prevent decrease in the number of oocytes in the ovaries.
