Q

OBG - 2.6
Which can cause Asherman’s syndrome?
A) infections leading to endometrial sclerosis (e.g. genitalis tuberculosis)
B) ovarian dysfunction
C) destruction of the endometrial basal layer (e.g. after curettage of the uterus)
D) all of them are correct
E) A and C

A

ANSWER
E) A and C
EXPLANATION
In the Asherman’s syndrome, the front and back walls of the uterus stick to one another, which leads to amenorrhea. The most common cause of this condition is iatrogenic because of the destruction of the endometrial basal layer e.g. after curettage of the uterus. Genital tuberculosis may also lead to Asherman’s syndrome through the infection-related endometrial sclerosis, but it’s uncommon nowadays.
