The
female reproductive system (or
female genital system) contains two main parts: the
uterus, which hosts the developing fetus, produces
vaginal and uterine secretions, and can pass
sperm through to the
Fallopian tubes; and the
ovaries, which produce the female's egg cells. These parts are internal; the vagina meets the external organs at the
vulva, which includes the
labia,
clitoris and
urinary meatus. The vagina is attached to the uterus through the
cervix, while the uterus is attached to the ovaries via the Fallopian tubes. At certain intervals, the ovaries release an
ovum, which passes through the Fallopian tube into the uterus. If, in this transit, it meets with sperm, a single sperm can enter and merge with the egg,
fertilizing it. Corresponding equivalent among males is the
male reproductive system.
