Müllerian Duct Anomalies: Embryological Development

  1. Any disruption of müllerian duct development during embryogenesis can result in a broad and complex spectrum of congenital abnormalities termed müllerian duct anomalies (MDAs). The ovaries and distal third of the vagina originate from the primitive yolk sac and sinovaginal bud, respectively
  2. The most common types of müllerian anomalies are: Müllerian agenesis, which is a failure to form the uterus and fallopian tubes. Disorders of fusion, which occur when the müllerian ducts fail to come together correctly. Often kidney problems develop in women with müllerian abnormalities, mainly because the kidneys develop next to the.

Mullerian duct anomalies are those structural anomalies caused by errors in müllerian-duct development during embryonic morphogenesis. Factors that precipitate include genetics, and maternal exposure to teratogens. Genetic causes of müllerian duct anomalies are complicated and uncommon Those 140 cases were clustered in 39 different types of anomalies. MAIN RESULTS AND THE ROLE OF CHANCE: The congenital anomaly involved a single organ in 12 (30.8%) out of the 39 types of anomalies, while multiple organs and/or segments of Müllerian ducts (complex anomaly) were involved in 27 (69.2%) types The complexity of developmental events in these systems is evident by the incomplete separation of the 2 systems found in some congenital anomalies.

The Müllerian ducts are paired embryologic structures that undergo formation, fusion and resorption in utero to give rise to the uterus, fallopian tubes, cervix, and upper two-thirds of the vagina. Interruption of the normal development of the ducts can result in Müllerian duct anomalies (MDAs) So here are four tips for correctly diagnosing uterine anomalies with ultrasound to try to prevent these common mistakes. 1.

These malformations are attributed to failure in organogenesis, fusion or reabsorption of the Müllerian ducts during early embryological development stages Müllerian anomalies have been described and categorized in several published classification systems, including the American Fertility Society/American Society for Reproductive Medicine classification of müllerian anomalies (2), the European Society of Human Reproduction and Embryology and European Society for Gynecological Endoscopy (ESHRE. No anomalies were present that could not be classified according to the ESHRE-ESGE criteria.

CUA -Embryology (Crosby & Hill) Paramesonephric (Müller) Ducts At 6 - 9 weeks of gestation: Müllerian ducts appear and there is a caudal midline fusion and connection with the urogenital sinus. So, failure of development of the Müllerian ducts during this period leads to uterine hypoplasia / aplasia. At 10 - 13 weeks of gestation Müllerian anomalies without a classification: from the didelphys-unicollis uterus to the bicervical uterus with or without septate vagina.

However, our review of the literature has failed to produce a `uterine triplication'; we herein report the first known case of an amenorrhoeic. Müllerian duct anomalies (MDA) occur due to abnormal development of the uterus, cervix, and vagina, many times affecting a woman's ability to conceive and carry a pregnancy to term. The spectrum of possible abnormalities are related to the development of two separate Müllerian systems, which then fuse and subsequently undergo degeneration of the fused segments. This multiphasic development.

The European Society of Human Reproduction and Embryology (ESHRE) and the European Society for Gynaecological Endoscopy (ESGE), recognizing the clinical signi ficance of female genital anomalies, have established a common working group under the name CONUTA (CONgenital UTerine Anomalies), with the goal of developing a ne M??llerian duct anomalies (MDA) can adversely affect pregnancy outcomes.

Abstract. To help physicians and radiologists in the diagnosis of female genito-urinary malformations, especially of complex cases, the embryology of the female genital tract, the basis for Müllerian development anomalies, the current classifications for such anomalies and the comparison for inclusion and cataloguing of female genital malformations are briefly reviewed Congenital uterine anomalies (CUAs) are deviations from normal anatomy resulting from embryological maldevelopment of the müllerian ducts. While most CUAs are asymptomatic and are associated with normal reproductive outcomes, some may be associated with adverse reproductive outcomes Müllerian anomalies without a classification: from the didelphys-unicollis uterus to the bicervical uterus with or without septate vagina. Fertil Steril 2009; The female gubernaculum: role in the embryology and development of the genital tract and in the possible genesis of malformations The female reproductive system derives from four origins: mesoderm, primordial germ cells, coelomic epithelium, and mesenchyme. The uterus forms during Mullerian organogenesis accompanied by the development of the upper third of the vagina, the cervix, and both fallopian tubes.

This is based on a developmental theory that postulates that müllerian duct fusion is unidirectional, beginning caudally and extending cranially, which does not account for isolated cervical or vaginal defects. More recently, the European Society of Human Reproduction and Embryology For example, Müllerian duct anomalies, such as uterine septa or bicornuate uterine configurations may be recognized in 1.9% of females undergoing transcervical tubal ligation. 1 About 5% of patients undergoing 3-dimensional ultrasound for evaluation of gynecologic concerns are identified to have uterine anomalies. 2 Twenty percent of women.

Embryology Two paired müllerian ducts ultimately develop into the structures of the female reproductive tract. The structures include the fallopian tubes, uterus, cervix, and upper two thirds of the vagina. The ovaries and lower one third of the vagina have separate embryologic origins not derived from the müllerian system Embryology of the uterus is an area of anatomical research that has long ago been considered as concluded as most of the anomalies do follow a pattern of complete or partial absence of Müllerian fusion. Little research has been done trying to understand the physiopathology of anomalies falling outside the common accepted explanation

Uterine duplication anomalies are a group of Müllerian duct anomalies where fusion of the Müllerian duct associated structures fail to some degree: uterus didelphys : class III. bicornuate uterus : class IV (second commonest duplication anomaly) septate uterus: class V (commonest duplication anomaly) 1-2 Human Reproduction and Embryology/European Society for Gynaecological Endoscopy (ESHRE/ESGE) in 2013 [4], Müllerian duct abnormalities can be classied into 36 dierent combinations as the main class for the uter-ine body (U) and subclasses for the cervix (C) and vagina (V). Compared to the classication method put forwar These anomalies result from failure of fusion of the paired müllerian ducts, but in some instances there is a true duplication of the ducts on one or both sides. Such duplications result from splitting of the müllerian duct during the seventh week of development. Accessory tubes or ovaries may be present Females with unilateral renal agenesis have a significant incidence of ipsilateral müllerian anomalies, and may present in early adolescence with a pelvic mass indicative of hydrometrocolpos due to any of a spectrum of uterine or vaginal anomalies, commonly uterus didelphys with an obstructed uterine horn Collectively, this sequence of anomalies is known as the Potter sequence.

Septate uterus results from the incomplete or completely failed fusion of Müllerian ducts and is the most common type among congenital uterine anomalies [1, 2].Two types of septate uterus are described: the complete septate uterus, in which the septum divides the whole uterine cavity, and the subseptate uterus, in which a partial separation of uterine cavity does not reach the cervix (Fig. 1a. Müllerian anomalies (MA) are among the most common diseases in gynecology and obstetrics. They include various malformations of fallopian tubes, vagina, cervix, and corpus uteri [].The estimated incidence of MA is 5.5% in the general population, but 24.5% in women with infertility and miscarriage [2, 3].This disease seriously affects women's reproductive function and causes a huge social. The true incidence of Müllerian duct anomalies (MDAs) are believed to be between 0.1 and 3.8% [].Although its incidence may be as high as 25% in women with recurrent miscarriages and subfertility [].MDAs are congenital anatomic abnormalities of the female genital tract that arise from nondevelopment or nonfusion of the Müllerian ducts or failed resorption of the uterine septum [3, 4]

The incidence of this anomaly has been historically cited in the literature as 1: 50 000. An epidemiological study of over 4 million births in the United Kingdom recorded a prevalence of 2.8 cases per 100 000 live births. However, the number of liveborn cases was matched by a comparable number of cases in which elective termination of pregnancy had been undertaken following prenatal detection. Among all of the müllerian duct anomalies, unicornuate uteri have the highest association of renal abnormalities, present in up to 40% of these women. The renal anomaly is ipsilateral to the abnormal horn. Most of the MDA have normal functioning ovaries and normal age appropriate external genitalia In females, the external genitalia, gonads, and müllerian ducts each derive from different primordia and in close association with the urinary tract and hindgut. Abnormal embryogenesis during this process is thought to be multifactorial and can create sporadic anomalies
