Q

What is the role of AMH in reproductive tract formation?

A

AMH drives degeneration of Mullerian duct (goes onto form uterus, cervix and upper vagina)

Lack of AMH leads to degeneration of Wolffian duct (goes onto form epididymis, vas deferens, seminal ducts)

Q

  2. Ensure bladder empty with Foley catheter

Next steps…

  1. Oxytocin 5 iu by slow IV
  2. Ergometrine 0.5mg slow IV or IM injection
  3. Oxytocin infusion

Further surgical steps…
