Ducts in the embryo that develop into the fallopian tubes, the uterus, and possibly the upper region of the vagina in females.
Embryonic tubes from which develop the female reproductive organs (oviducts, uterus, vagina).
The Mullerian and the Wolffian ducts are separate sets of primordia that transiently co-exist in embryos of both sexes. In female embryos the Mullerian ducts grow and fuse in the mid line, producing the fallopian tubes, the uterus and the upper third of the vagina, whereas the Wolffian ducts regress. In the male the Wolffian ducts give rise to the vas deferens, the seminal vesicles and the epididymis, and the Mullerian ducts disappear. This latter development requires a functioning testis from which an inducer substance diffuses ‘locally over the primordia to bring about the suppression of the Mullerian duct and the development of the Wolffian duct. In the absence of this substance, development proceeds along female lines, irrespective of the genetic sex.
One of the bilateral ducts in the embryo that form the uterus, vagina, and fallopian tubes.
In the developing embryo, there is a duct that, in females, gives rise to the Fallopian tubes, uterus, and vagina. In males, this duct regresses, leaving behind a small, closed cavity known as the prostatic utricle, essentially representing the vestige of the uterus in males.
