Derivatives of paramesonephric (Mullerian) ductIn male

1. Upper-most part- Appendix of testis2. Lowest part-

Prostatic utricle

In female1. Upper-most part- Appendix of fallopian tube2. Upper vertical and middle horizontal part-

Fallopian tube3. Lower vertical part-It form utero-vaginal canal after fusion with opposite side.

a) Upper part- Uterusb) Lower part- Upper part of vagina
