MÜLLERIAN ANOMALIES

Uterine anomalies (3% of fertile women, with normal reproductive outcomes)
are classified into 7 types (per American Fertility Society 1988) based on the
developmental problem responsible for the irregular shape.

Uterine anomalies may result from 3 mechanisms:

Stage   1:  failure of  one or  both    of  the 2   Müllerian   ducts   to  form

Stage   2:  failure of  the 2   ducts   to  fuse    completely

Stage   3:  failure of  the 2   fused   Müllerian   ducts   to  dissolve    the septum  that

results from    fusion
