Question

Uterine didelphys will cause all of the following symptoms except?

• A. Transverse lie
• B. Endometriosis
• C. Repeated abortion
• D. Premature labor

Hint:

Think about which condition results from retrograde menstruation rather than a structural uterine anomaly.

Answer 1

The Correct Option is B

Step 1: Define uterine didelphys.
Uterine didelphys (double uterus) is a Mullerian duct anomaly in which there is complete non-fusion of the Mullerian ducts, resulting in two separate uteri, two separate cervices, and often two vaginas (with a longitudinal vaginal septum).

Step 2: List known complications of uterine didelphys.
Uterine didelphys is associated with:
- Infertility
- Repeated (recurrent) miscarriage / spontaneous abortion
- Premature labor and premature birth
- Transverse lie (the smaller uterine cavity can predispose to malpresentation)
- Kidney problems (renal agenesis on the side of the hemi-uterus)

Step 3: Identify what is NOT caused by uterine didelphys.
Endometriosis is NOT a recognized complication of uterine didelphys. Endometriosis is caused by retrograde menstruation implanting endometrial tissue outside the uterus; this is an independent condition unrelated to Mullerian fusion anomalies.

Step 4: Conclusion.
Endometriosis is the exception - it is not caused by uterine didelphys.
