Is the start of menopause determined by the woman's number of pregnancies?

When a woman is likely to begin menopause is not based on the number of pregnancies you may have had, but partly on maternal history—meaning, your mother's age at menopause. Menopause is based on the brain's effect on the ovaries and their production of hormones. Lifestyle may also play a role, and some diseases like certain autoimmune conditions may bring on menopause early.The number of pregnancies does not affect this process or timing.

There has been some research attempting to link the number of pregnancies a women has to the age of menopause. Researchers do know that the age you go through menopause depends on a combination of factors including when your relatives went through it, your body mass index (BMI), and environmental factors such as smoking. Women with a high BMI go through menopause later and smokers go through it earlier.
