The uterus or womb is the major female reproductive organ. The uterus provides mechanical protection, nutritional support, and waste removal for the developing embryo (weeks 1 to 8) and fetus (from week 9 until the delivery). In addition, contractions in the muscular wall of the uterus are important in pushing out the fetus at the time of birth.

Fetus in fetu (or foetus in foetu) is a rare developmental abnormality in which a mass of tissue resembling a fetus forms inside the body of its twin. An early example of the phenomenon was described in 1808 by George William Young. [1] There are two hypotheses for the origin of a fetus in fetu.
The uterus (from Latin uterus, pl.: uteri or uteruses) or womb (/ w uː m /) is the organ in the reproductive system of most female mammals, including humans, that accommodates the embryonic and fetal development of one or more fertilized eggs until birth. [1]
In 2019, a woman living in Bangladesh with a double uterus gave birth to three babies — first, a baby from one uterus, and then, 26 days later, twins from her second uterus.
Leonardo mistakenly depicted the cotyledons in the vascular walls of the human uterus that he had previously found in a cow uterus. [3] The other study, measuring 30.3×22 cm, shows female external genitalia , the supposed arrangement of abdominal muscles on the top right and fetus from different angles.
