Question

What would happen with regard to the development of the paramesonephric ducts and the mesonephric ducts in each of the following scenarios:

1. In a genetically female embryo, if the indifferent gonad was removed:

paramesonephric ducts –

mesonephric ducts –

2. In a genetically male embryo, if the indifferent gonad was removed:

paramesonephric ducts -

mesonephric ducts -

3. In a genetically female embryo, if the indifferent gonad was removed and the embryo treated with MIH and testosterone:

paramesonephric ducts –

mesonephric ducts -

Answer 1

case 1 feamle embryo XX chromosome gonad removed so NO Anti mullerian harmone (AMH)	paramesonephric duct(Mullerian) due to absent of AMH, develops to Follipian tube and Uterus .	mesonephric ductWolffian) No development .
Case 2 Male embryo XY chromosome Gonad removed so NO AMH	paramesonephric duct(Mullerian) due to absent of AMH, develops to Follipian tube and Uterus .	mesonephric ductWolffian) No development
case 3 female embryo , XX chromosome Gonad removed Mullerian inhibiting hormone and testoterone given	paramesonephric duct(Mullerian) suppressed by MIH NO development	mesonephric ductWolffian) due to testoterone devopled into Vas deferens and seminal vesicle
