The Mayer-Rokitansky-Küster-Hauser syndrome (MRKH) is characterized by congenital aplasia of the uterus and 2/3 of the upper vagina in women with normal development of secondary sexual characteristics and a normal karyotype. The two structures have their origins from Mullerian tissue (ovaries arise separately from the gonadal ridge).
The syndrome can be thought of as two types:
- type I: agenesis of the uterus and the upper portion of the vagina
- type II: an association of renal defects, vertebral and, to a lesser extent, to auditory and cardiac alterations (MURCS)
The first clinical sign of the syndrome is a primary amenorrhea in young women with normal development of secondary sexual characteristics and normal external genitalia, with normal and functional ovaries, in addition to karyotype 46, XX.
