The ovaries can still produce estrogen after menopause, according to the National Institute of Aging. The ovaries do not necessarily stop producing estrogen. The productions of all female hormones can vary greatly during and after menopause.
The body's release of female hormones during menopause is very unpredictable and different for each woman, according to the National Institute of Aging. Estrogen and progesterone are both produced by the ovaries and vary dramatically throughout menopause. Estrogen is still needed for many different organs in the body. Progesterone levels lower after menopause, while luteinizing hormone levels increase. A blood test can indicate the actual levels of various hormones after menopause.
