Most of us are taught about the reproductive functions of the uterus and about menstruation, and that's where the education stops.
The uterus is a sex organ. Women who experience uterine orgasm do not experience it after their uterus is removed. The ovaries are the female gonads. The ovaries produce all of the hormones women need all of their life. There is no age and no time when the uterus and ovaries are not needed.
