Müllerian anomalies can be part of a multiple malformation syndrome. [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.
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 and the vagina), while the other duct regresses. In PMDS, an abnormality in the anti-Müllerian hormone signaling pathway causes the in-males-redundant ...
A male that has persistent Müllerian duct syndrome may have an upper vagina, uterus, and uterine tubes as well as ductus deferens along with male external genitalia. The female organs are in the correct anatomical position but the position of the testis varies. 60% to 70% of detected cases, both testes will lie in the normal position for the ...
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 ...
XX male syndrome, also known as de la Chapelle syndrome, is a rare intersex condition in which an individual with a 46,XX karyotype develops a male phenotype. [2] Synonyms for XX male syndrome include 46,XX testicular difference of sex development (or 46,XX DSD) [3] [4] [5] [6]
The internal genitalia consist of two accessory ducts: mesonephric ducts (male) and paramesonephric ducts (female). The mesonephric system is the precursor to the male genitalia and the paramesonephric to the female reproductive system. [8] As development proceeds, one of the pairs of ducts develops while the other regresses.
Vaginal anomalies are abnormal structures that are formed (or not formed) during the prenatal development of the female reproductive system and are rare congenital defects that result in an abnormal or absent vagina. [1] When present, they are often found with uterine, skeletal and urinary abnormalities.
