Congenital structural abnormalities of the UROGENITAL SYSTEM in either the male or the female.

The hollow thick-walled muscular organ in the female PELVIS. It consists of the fundus (the body) which is the site of EMBRYO IMPLANTATION and FETAL DEVELOPMENT. Beyond the isthmus at the perineal end of fundus, is CERVIX UTERI (the neck) opening into VAGINA. Beyond the isthmi at the upper abdominal end of fundus, are the FALLOPIAN TUBES.

Contraction of the UTERINE MUSCLE.

Endometrial implantation of EMBRYO, MAMMALIAN at the BLASTOCYST stage.

The status during which female mammals carry their developing young (EMBRYOS or FETUSES) in utero before birth, beginning from FERTILIZATION to BIRTH.

The process of bearing developing young (EMBRYOS or FETUSES) in utero in non-human mammals, beginning from FERTILIZATION to BIRTH.

The smooth muscle coat of the uterus, which forms the main mass of the organ.

The neck portion of the UTERUS between the lower isthmus and the VAGINA forming the cervical canal.

The mucous membrane lining of the uterine cavity that is hormonally responsive during the MENSTRUAL CYCLE and PREGNANCY. The endometrium undergoes cyclic changes that characterize MENSTRUATION. After successful FERTILIZATION, it serves to sustain the developing embryo.

Pathological processes involving any part of the UTERUS.

A complete separation or tear in the wall of the UTERUS with or without expulsion of the FETUS. It may be due to injuries, multiple pregnancies, large fetus, previous scarring, or obstruction.

Delivery of an infant through the vagina in a female who has had a prior cesarean section.

Allowing a woman to be in LABOR, OBSTETRIC long enough to determine if vaginal birth may be anticipated.

Surgical removal of a LEIOMYOMA of the UTERUS.

Forcible or traumatic tear or break of an organ or other soft part of the body.

Extraction of the fetus by abdominal hysterotomy anytime following a previous cesarean.

Extraction of the FETUS by means of abdominal HYSTEROTOMY.
