APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -Organogenesis is characterised by the formation of both Müllerian ducts. Failure of this results in uterine agenesis/hypoplasia or a unicornuate uterus. Fusion is characterised by fusion of the ducts to form the uterus. Failure of this results in a bicornuate or didelphys uterus.

Detailed explanation-2: -Uterine didelphys: The entire uterus and cervix is duplicated (also called a didelphic uterus), which creates two uteri and two cervices. The patient still has the standard two fallopian tubes and two ovaries. This condition is the result of the two Müllerian ducts developing, but not fusing together at all.

Detailed explanation-3: -The development of the paramesonephric (Müllerian) ducts is controlled by the presence or absence of anti-Müllerian hormone (AMH; also known as Müllerian-inhibiting substance, “MIF” for “Müllerian-inhibiting factor", “MIH” for “Müllerian-inhibiting hormone", or “APH” for anti-paramesonephric hormone).

Detailed explanation-4: -The Müllerian ducts are paired tubes that develop into the female reproductive organs. This happens while a fetus is growing in the womb. Both males and females have Müllerian ducts at first. But during sexual differentiation (development of female or male sex organs), that changes.

Detailed explanation-5: -Failure of Fusion of the Paramesonephric Ducts Fusion of the caudal portion of the paramesonephric ducts forms the uterine body, cervix, and (cranial) vagina. Complete failure of fusion results in uterus didelphys, a condition in which the uterine body, cervical canal, and cranial vagina are all duplicated.
