This document discusses uterine anomalies, their prevalence in the general and infertile populations, and their clinical presentations. Uterine anomalies are classified into three groups based on embryonic development defects: 1) agenesis of the uterus and vagina, 2) defects in vertical fusion that can be obstructive or non-obstructive, and 3) lateral fusion defects that can also be obstructive or non-obstructive. Specific types of uterine anomalies include unicornuate, bicornuate, septate, subseptate, arcuate, and didelphys uteri.

1. Uterine anomalies

2. • 􀁺 Prevalence in general population 1 in 201
(0.5%)
• 􀁺 According to “Acien,” 2-3% of fertile women
and
• 3% of infertile women and 5-10% of those with
• repeated miscarriages.
• 􀁺 Distribution: 7% arcuate, 34% septate, 39%
• bicornuate, 11% didelphic, 5% unicornuate, 4%
• hypoplastic/asplastic/solid and other forms

4. Classification into 3 groups:
Based on similar embryonic development
defects and clinical presentation
. Agenesis of uterus/vagina: RokitanskyKuster-Hauser Syndrome.
􀁺 2. Defects in Vertical Fusion (obstructive
or
non-obstructive)
􀁺 3. Lateral Fusion defects (obstructive or
non-obstructive).
