Definition / general
  • Develops from mesoderm-derived Müllerian (paramesonephric) ducts
  • Cranial end of Müllerian ducts become future fallopian tubes; caudal ends fuse in midline to form Y shaped canal (uterovaginal primordium)
  • Uterovaginal primordium meets endoderm derived urogenital sinus at Müllerian tubercle (location of vaginal orifice at hymenal ring)
  • Uterovaginal primordium gives rise to fibromuscular wall of vagina, epithelium and glands of corpus uteri and cervix; endometrium and stroma develop from adjacent mesenchyme
  • Epithelium of vagina is largely derived from urogenital sinus by upgrowth of sinovaginal bulbs that fuse to form vaginal plate, which subsequently breaks down centrally, leaving periphery as vaginal epithelium
  • Acien classification: Hum Reprod Update 2011;17:693
  • DES exposed female fetus is at risk for congenital malformation of cervix and vagina
