[1] [3] Studies have estimated that Mullerian anomalies can affect between 4 percent and nearly 7 percent of the female population. [4] [5] Müllerian anomalies occur as a congenital malformation of the Müllerian ducts during embryogenesis.
Müllerian agenesis, also known as Müllerian aplasia, vaginal agenesis, or Mayer–Rokitansky–Küster–Hauser syndrome (MRKH syndrome), is a congenital malformation characterized by a failure of the Müllerian ducts to develop, resulting in a missing uterus and variable degrees of vaginal hypoplasia of its upper portion.
The two Müllerian ducts have fused, but the partition between them is still present, splitting the system into two parts. With a complete septum the vagina, cervix and the uterus can be partitioned. Usually the septum affects only the cranial part of the uterus. A uterine septum is the most common uterine malformation and a cause for ...
Anomalies that develop within the paramesonephric duct system continue to puzzle and fascinate obstetricians and gynecologists. The paramesonephric ducts play a critical role in the female reproductive tract and differentiate to form the uterine tubes, uterus, superior vagina as well as the uterine cervix.
Many of these defects are classified under the broader term Müllerian duct anomalies. [2] [4] Müllerian duct anomalies are caused by a disturbance during the embryonic time of genitourinary development. [5] The other isolated incidents of vaginal anomalies can occur with no apparent cause.
A bicornuate uterus is an indication for increased surveillance of a pregnancy, though most women with a bicornuate uterus are able to have healthy pregnancies. [1] Women with a bicornuate uterus are at an increased risk of recurrent miscarriage, [2] [10] preterm birth, [2] [11] malpresentation, [2] [12] disruptions to fetal growth, [13] premature rupture of membranes, placenta previa and ...
It is a type of abnormality of the Müllerian ducts. In most cases, OHVIRA presents as a double uterus–either bicorneate or didelphys– with unilateral obstructed (or blind) hemivagina and ipsilateral renal agenesis (or renal anomalies). It can also affect the urethra, urethral sphincter, ureters, bladder and spleen
The fetus has two sets of tubes which give rise to accessory reproductive organs - the (Wolffian) mesonephric ducts and the (Müllerian) paramesonephric ducts. Usually, the Wolffian duct gives rise to male reproductive organs (specifically the testicle, epididymis and vas deferens) while the Müllerian to female (the fallopian tubes, the uterus ...
