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.
The cervical canal connects the interior of the vagina and the cavity of the body of uterus. The cervix is part of the female reproductive system. Around 2–3 centimetres (0.8–1.2 in) in length, [3] it is the lower narrower part of the uterus continuous above with the broader upper part—or body—of the uterus. [4]
Symptoms depend on whether the cervical canal is partially or completely obstructed and on the patient's menopausal status. Pre-menopausal patients may have a build up of blood inside the uterus which may cause infection, sporadic bleeding, or pelvic pain.
The labia majora are closed. [43] These changes disappear over the first few months. [42] During childhood before puberty, the lack of estrogen can cause the labia to become sticky and to ultimately join firmly together. This condition is known as labial fusion and is rarely found after puberty when estrogen production has increased. [44]
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 the 16th and 17th centuries, medical researchers mistakenly saw the presence or absence of the hymen as founding evidence of physical diseases such as "womb-fury", i.e., (female) hysteria. If not cured, womb-fury would, according to doctors practicing at the time, result in death. [39] [40]
The vaginal cuff is the upper portion of the vagina that opens up into the peritoneum and is sutured shut after the removal of the cervix and uterus during a hysterectomy. [1] [2] The vaginal cuff is created by suturing together the edges of the surgical site where the cervix was attached to the vagina.
A niche, also known as a Cesarean Scar Defect or an Isthmocele, is a defect in the wall of the uterus after a cesarean section. [2] You can imagine it as if the wound of the uterus is being closed after a cesarean section, but it's receding a little bit at the inside of the uterus.
