Menopause is the natural end to menstruation. The average age of menopause in the US is 52 years old. However, it can start around age 40 and as late as around age 60. If menopause occurs prior to age 40, it is thought to be abnormal and is called premature menopause.
Menopause is the result of the depletion of egg cells from the ovaries and the reduction of female hormones. Menopause is considered complete when you have been without a menstrual period for a full year. Rather than a single point in time, menopause is a process or transitional period when women move away from the phase of life where reproduction is possible.
Menopause is a normal part of life. It marks the end of a long, slow process that begins when ovaries begin to produce less estrogen and progesterone. These female hormones are both important for normal menstrual cycles and successful pregnancy. An
oophorectomy (removal of the ovaries) in women of reproductive age causes surgical menopause.
In addition to its role in reproduction, estrogen is an important hormone for maintaining bone health. It may also play important roles in heart health, skin elasticity, and brain function.
