Final answer:
The pregnancy rates after surgical correction of transverse vaginal septum vary depending on the location of the septum.
Step-by-step explanation:
The pregnancy rates after surgical correction of transverse vaginal septum vary depending on the location of the septum. The lower 1/3 septum has the highest pregnancy rates among the three levels. Surgical correction of the lower 1/3 septum has shown to improve pregnancy rates. The middle 1/3 septum also has a positive effect on pregnancy rates, although not as high as the lower 1/3. The upper 1/3 septum may have lower pregnancy rates compared to the other two levels, but surgical correction can still have a positive impact on fertility.
