Female Anatomical Abnormalities Flashcards
Pelvic organs are vascularized by what?
Internal Illiac Artery (anterior branch)
Male sex organs come from which duct?
Wolfian duct….also known as the Mesonephric duct
Female sex organs come from which duct
Mullerian….also known as the Paramesonephric duct
Canalization of the female sex organs (vagina, uterus) goes caudal to cranial
ok
Canalization is complete at what point in fetal development?
20 weeks
What makes the Wolfian duct develop instead of the Mullerian?
Androgens….testosterone and DHT (two main hormones). Females experience much less androgen formation
Know this. Females don’t have hormones that make the wolfian ducts disappear, its just the absence of Androgens. Males do have anti-mullerian hormone produced by the sertoli cells. Called AMH.
ok. So if a gonad doesn’t produce androgen, external genitalia appear female by default.
Are Mullerian anomalies genetic?
No. You will not see any mutations on Karyotype. However, it does tend to run in families.
Know the Mullerian abnormalities slide
ok
Vaginal agenesis
no vagina
cervical agenesis
no cervix
Fundal agenesis
no uterus pretty much
Tubal agenesis
No tubes
Unicornuate uterus =
uterus formed by only one of the mullerian ducts
Didelphus
Pretty much the two mullerian ducts don’t fuse. You end up with two separate cervices, two separate vaginas in many cases.
