There is not one cause of müllerian anomalies. Some may be hereditary, others may be attributed to a random gene mutation or developmental defect.
Are uterine anomalies genetic?
Several genes have been identified in the abnormal and normal development of the uterus, cervix, fallopian tubes, and vagina. Many anomalies are felt to be multifactorial; however there are case reports of familial inheritance suggesting that specific genetic mutations may cause these defects .
What causes Mullerian duct anomalies?
Typically, some of the tissue migrates upwards to form the uterus and fallopian tubes, and the remaining tissue migrates downwards to form the vagina. Any disruption in this process may result in a malformation of the uterus, vagina, or both, which leads to a Müllerian anomaly.
What is Mullerian defect?
When this happens, a single uterus with an open cavity and two fallopian tubes are formed. Sometimes the uterus and fallopian tubes may not form like they should. These malformations are called müllerian anomalies or defects. Müllerian anomalies may make it difficult or impossible to become pregnant.
WHO classification müllerian anomalies?
The most widely accepted method of categorizing müllerian duct anomalies is the AFS classification (1988). This system organizes müllerian anomalies according to the major uterine anatomic defect. It also allows for standardized reporting methods.

What does Mullerian mean?
: of, relating to, or being mimicry that exists between two or more inedible or dangerous species (as of butterflies or bees) and that is considered in evolutionary theory to be a mechanism which reduces loss to predation by simplifying the warning colors and patterns a predator must recognize Mullerian mimicry differs ...
How are Mullerian anomalies diagnosed?
The role of imaging is to help detect, classify and guide surgical management. At this time, MRI is the modality of choice because of its high accuracy in detecting and accurately characterising Müllerian duct anomalies.
How common are Mullerian anomalies?
Müllerian anomalies affect up to four percent of females. The anomaly is considered a 'congenital disorder', meaning it occurs during fetal development and is present at birth.
What is Mullerian duct in male?
Collapse Section. Persistent Müllerian duct syndrome is a disorder of sexual development that affects males. Males with this disorder have normal male reproductive organs , though they also have a uterus and fallopian tubes, which are female reproductive organs .
What is a Mullerian tumor?
Listen to pronunciation. (myoo-LAYR-ee-un TOO-mer) A rare cancer of the uterus, ovary, or fallopian tubes.
What is Mullerian duct in female?
The Müllerian duct (MD) is the embryonic structure that develops into the female reproductive tract (FRT), including the oviduct, uterus, cervix and upper vagina. The FRT has essential functions in mammals, providing the site of fertilization, embryo implantation and fetal development.
What is the function of Mullerian duct?
The function of the Mullerian ducts is to give rise to the organs that function in female reproduction. In the male, these ducts will disappear through atrophy.
Do males have müllerian ducts?
…ducts, called the paramesonephric or müllerian ducts, persist, in females, to develop into the fallopian tubes, the uterus, and part of the vagina; in males they are largely suppressed.
How common is uterine anomalies?
Congenital uterine anomalies occur in less than 5% of all women, but have been noted in up to 25% of women who have had miscarriages and/or deliveries of premature babies. When a woman is in her mother's womb, her uterus develops as two separate halves that fuse together before she is born.
How is uterine anomaly treated?
Many women with uterine anomalies do not require treatment. If pain, miscarriage, or infertility is an issue, a physician may recommend correcting the anomaly surgically. Most cases of uterine anomalies can be corrected through minimally invasive techniques, such as laparoscopy or hysteroscopy.
What are the congenital uterine anomalies?
Congenital uterine anomalies, also called Müllerian duct anomalies, are female reproductive malformations that can increase the risk of infertility or adverse pregnancy outcomes, such as miscarriage, intrauterine growth restrictions and preterm delivery.
What male body part comes from Mullerian ducts?
Wolffian ducts in males generate the tube of the epididymus, ductus deferens, ejaculatory duct, and seminal vesicle.
Can a man be born with ovaries?
Intersex is a term used to describe people who bear both external genitals and internal organs, such as testes and ovaries. A person with the condition may have male genitals along with fallopian tubes and ovaries. ... According to the Intersex Society of North America, more than 1,500 children a year are born intersex.
What is Paramesonephric duct in male?
Anatomical terminology. Paramesonephric ducts (or Müllerian ducts) are paired ducts of the embryo that run down the lateral sides of the urogenital ridge and terminate at the sinus tubercle in the primitive urogenital sinus.
What is a septum in pregnancy?
A septate uterus is when a thin tissue membrane, called the septum, runs down the middle of the uterus (i.e., the womb) and divides it into two separate parts. This condition occurs when the baby is developing in the womb, making it the most common abnormality related to the uterus in women.
How is uterine anomaly diagnosed?
Multiple imaging modalities exist to diagnose the presence of uterine anomalies. These include 2-dimensional (2D) ultrasound, 3D transvaginal ultrasound, saline infusion sonohysterography (SIS), hysterosalpingography (HSG), diagnostic hysteroscopy, and magnetic resonance imaging (MRI).
What is Mullerian and Wolffian ducts?
The Müllerian duct gives rise to female reproductive organs, such as the oviduct and uterus. During gestation, the Wolffian duct, which generates male reproductive organs and the kidney, is formed, and the Müllerian duct then elongates caudally along the preformed Wolffian duct.
What is Mullerian dysgenesis?
Mullerian dysgenesis is defined as the absence or hypoplasia of mullerian duct-derived structures, including the fallopian tubes, uterus, and the upper two-thirds of the vagina.
What is Mullerian origin?
Adenocarcinoma of Mullerian origin, previously, known as 'mesothelioma of pelvic origin', is a rare primary malignancy of the peritoneum . It is frequently found identical to papillary serous adenocarcinoma of the ovary, hence, also referred to as extraovarian peritoneal serous papillary carcinoma.
Is MMMT curable?
The prognosis of MMMT is universally bad, ranging from 12 to 20% five-year survival. Associated with a good prognosis are a limited extent of the disease in relation to myometrial and cervical involvement and absence of vascular invasion within the endometrium.
