The Müllerian duct is an embryological structure that develops into the female internal reproductive organs. 

 

               Development Of Female Reproductive Organism From Mullerian Duct

 

In early embryonic life (about 6 weeks of gestation), both sexes have two duct systems:

1. Müllerian ducts (paramesonephric ducts)

2. Wolffian ducts (mesonephric ducts)

In females

Since there is no Anti-Müllerian hormone (AMH), the Müllerian ducts persist and differentiate.

They form:

• Fallopian tubes

• Uterus

• Cervix

• Upper two-thirds of the vagina
