... is typically classified based on whether or not the division extends to the external cervical os. Bicornuate uteri with a division above the os are called bicornuate unicollis and those with a divided os are called bicornuate bicollis.[2] There is a continuous range of the degree and location of the fusion of the paramesonephric ducts, and existence of a spectrum, rather than a fixed number of types corresponding to strict medical definitions. Two processes that occur during the embryonic development of the paramesonephric ducts - fusion and reabsorption - can be affected to different degrees.[3] There is also a hybrid bicornuate uterus: External fundal depressions of variable depths associated with a septate uterus can be seen by laparoscopy, indicating the coexistence of the two anomalies. These cases are candidates for hysteroscopic metroplasty under appropriate sonographic and/or laparoscopic monitoring.[4] An obstructed bicornuate uterus showing ...

The uterus is part the female reproductive system. Other structures and organs that are part of the reproduction system are the vagina, ovaries and fallopian tubes.[3] The uterus has four main parts. The fundus is the upper part of the uterus. It has a rounded shape. Another part of the uterus is the body. The uterotubal angles are the parts connected to the Fallopian tubes. The bottom part of the uterus is the cervix.[4] The uterus has three layers. The outer layer is called the perimetrium.[5] It is a thin layer that surrounds the outside of the uterus. The perimetrium is made of tissue made of epithelial cells. The middle layer is the myometrium. Most of the uterus is made up of the myometrium.[6] The layer on the inside is the endometrium. The endometrium is made of secretory, ciliated, and basal cells.[4] The uterus is ...

... is an obstetrical complication whereby a growing retroverted uterus becomes wedged into the pelvis after the first trimester of pregnancy. A number of situations may interfere with the natural process that would antevert a retroverted uterus during pregnancy. Such situations include pelvic adhesions, endometriosis, uterine malformations, leiomyomata, and pelvic tumors. When the uterus is tilted backwards, it is considered to be retroverted; this situation is common and regarded a normal variation. It has been estimated that about 15% of pregnancies begin in a retroverted uterus. Normally, during the first trimester, the growing uterus changes spontaneously to an anteverted position, thus allowing expansion of the enlarging uterus into the abdomen. The cervix is then inferior to the body of the uterus. Thus, the presence of an early pregnancy in a retroverted uterus is ...

... are two colored annotated sketches by Leonardo da Vinci made in 1510-1512/13. The studies correctly depict the human fetus in its proper position inside the dissected uterus. Da Vinci depicted the uterus with one chamber, in contrast to theories that the uterus had multiple chambers which many believed divided fetuses into separate compartments in the case of twins. Da Vinci also correctly drew the uterine artery and the vascular system of the cervix and vagina. Da Vinci studied human embryology with the help of anatomist Marcantonio della Torre and saw the fetus within a cadaver. The first study, measuring 30.5×22 cm, shows the fetus in a breech position inside a dissected uterus. Da Vinci mistakenly depicted the cotyledons in the vascular walls of the human uterus that he had previously found in a cow uterus. The other study, measuring 30.3×22 cm, shows female external genitalia, the supposed ...

The myometrium is the middle layer of the uterine wall, consisting mainly of uterine smooth muscle cells (also called uterine myocytes), but also of supporting stromal and vascular tissue. Its main function is to induce uterine contractions. The myometrium is located between the endometrium (the inner layer of the uterine wall), and the serosa or perimetrium (the outer uterine layer). Myometrium has 3 layers: outer longitudinal smooth muscles, middle crisscrossing (figure of eight) muscle fibres, and inner circular fibres. Middle crisscross fibres act as living ligature during involution of the uterus and prevent blood loss. The inner one-third of the myometrium (termed the junctional or sub-endometrial layer) appears to be derived from the Müllerian duct, while the outer, more predominant layer of the myometrium appears to originate from non-Müllerian tissue, and is the major contractile tissue during parturition and abortion. The junctional layer appears to function like a circular muscle ...

Inside the thick part of the uterus are blood vessels and other nutrients that a baby will need to grow. If an ovum in the uterus gets fertilized, it sticks to the wall of the uterus and starts to grow. However, if the ovum is not fertilized, it does not stick. The uterus then gets rid of the ovum and the extra tissue by releasing it from the body. The tissue and blood flows out of the uterus through the vagina. This is called menstruation or having a period. The bleeding normally lasts about 3-5 days, though some girls may bleed longer or have a bit of bleeding between periods.[1] The uterus then starts preparing for another ovum. For most girls, the time between their periods is about one month. For about 2 years after menstruation starts, the time between periods is not always the same.[2] Some girls may skip a month, or have 2 periods close to each other. It is also ...

The uterine microbiome is the commensal, nonpathogenic, bacteria, viruses, yeasts/fungi present in a healthy uterus, amniotic fluid and endometrium and the specific environment which they inhabit. It has been only recently confirmed that the uterus and its tissues are not sterile. Due to improved 16S rRNA gene sequencing techniques, detection of bacteria that are present in low numbers is possible. Using this procedure that allows the detection of bacteria that cannot be cultured outside the body, studies of microbiota present in the uterus are expected to increase. Bacteria, viruses and one genus of yeasts are a normal part of the uterus before and during pregnancy. The uterus has been found to possess its own characteristic microbiome that differs significantly from the vaginal microbiome. Despite its close spatial connection with the vagina, the microbiome of the uterus more closely resembles the ...

... , also called uterine massage, is a technique used to reduce bleeding and cramping of the uterus after childbirth or after an abortion. As the uterus returns to its nonpregnant size, its muscles contract strongly, which can cause pain. Fundal massage can be performed with one hand over the pubic bone, firmly massaging the uterine fundus (the top of the uterus), or with the addition of one hand in the vagina compressing the two uterine arteries. Routine use of fundal massage can prevent postpartum or post-abortion hemorrhage and can reduce pain; it may also reduce the need for uterotonics, medications that cause the uterus to contract. It is used to treat uterine atony, a condition where the uterus lacks muscle tone and is soft to the touch instead of firm.[1][2][3][4][5] ...

The female reproductive system likewise contains two main divisions: the vagina and the Ovum. The ovum meets with sperm cell, a sperm may penetrate and merge with the egg, fertilizing it with the help of certain hydrolytic enzymes present in the acrosome. The fertilization usually occurs in the oviducts, but can happen in the uterus itself. The zygote then becomes implanted in the lining of the uterus, where it begins the processes of embryogenesis and morphogenesis. When the fetus is developed enough to survive outside of the uterus, the cervix dilates and contractions of the uterus propel it through the birth canal, which is the vagina. The ova, which are the female sex cells, are much larger than the spermatozoon and are normally formed within the ovaries of the female fetus before its birth. They are mostly fixed in location within the ovary until their transit to the uterus, and contain nutrients for the later zygote ...

... is the surgical removal of the uterus. It may also involve removal of the cervix, ovaries, fallopian tubes and other surrounding structures. Usually performed by a gynecologist, hysterectomy may be total (removing the body, fundus, and cervix of the uterus; often called "complete") or partial (removal of the uterine body while leaving the cervix intact; also called "supracervical"). It is the most commonly performed gynecological surgical procedure. In 2003, over 600,000 hysterectomies were performed in the United States alone, of which over 90% were performed for benign conditions. Such rates being highest in the industrialized world has led to the major controversy that hysterectomies are being largely performed for unwarranted and unnecessary reasons. Removal of the uterus renders the patient unable to bear children (as does removal of ovaries and fallopian tubes) and has surgical risks as well as long-term effects, ...

In the female the paramesonephric ducts persist and undergo further development. The portions which lie in the genital cord[citation needed] fuse to form the uterus and vagina. This fusion of the paramesonephric ducts begins in the third month, and the septum formed by their fused medial walls disappears from below upward. The parts outside this cord remain separate, and each forms the corresponding Fallopian tube. The ostium of the fallopian tube remains from the anterior extremity of the original tubular invagination from the abdominal cavity. About the fifth month a ring-like constriction marks the position of the cervix of the uterus, and after the sixth month the walls of the uterus begin to thicken. For a time the vagina is represented by a solid rod of epithelial cells. A ring-like outgrowth of this epithelium occurs at the lower end of the uterus and marks the future vaginal fornix. At about the ...
