Which is more important, the uterus or the ovaries? Both the uterus and ovaries are very important for women. The uterus is the organ that gives birth to life, and the organ that allows women to menstruate, without the uterus it is impossible to give birth to life, so for women who want to have children the uterus is very important. For those who have already had children, the uterus and ovaries are relatively less important than the ovaries. The ovaries play a large role in maintaining a woman’s physical appearance and have two major functions, one is the endocrine function and the other is the reproductive function. The endocrine function is the secretion of three hormones, estrogen and progesterone, as well as a small amount of androgens. The reproductive function is the follicle on the ovary to each month will mature a follicle as the seed of life, because the ovary can secrete hormones, so it is more important for women. If you have to say which is more important, then the ovaries are more important than the uterus, especially for women who have given birth.
