Uterus With Asherman's Syndrome, Internal View

Description

Uterine cavity anatomy is presented from an internal luminal perspective, emphasizing intrauterine synechiae consistent with Asherman’s syndrome. Fibrous adhesions span between opposing endometrial surfaces, partially obliterating the central cavity from the fundus toward the lower uterine segment, with tethering that can narrow the region of the internal os. Inferiorly, the endocervical canal is constricted and partly occluded by the same scar bands, blurring the usual continuous passage from cavity to cervix. The uterine cornua and proximal tubal ostial regions are implied as potential sites of segmental obstruction when adhesions extend laterally. These adhesions matter because they turn a normally distensible endometrial cavity into a scarred, noncompliant space, a common substrate for secondary amenorrhea, hypomenorrhea, infertility, and recurrent pregnancy loss after endometrial trauma such as dilation and curettage, postpartum curettage, or uterine infection. The fixed internal vantage point mirrors what clinicians conceptualize during hysteroscopy, where adhesions may appear as avascular fibrous bridges that can hide landmarks and make orientation at the fundus, internal os, and tubal ostia uncertain. Scar distribution also frames risk discussions, since severe cavity obliteration correlates with poor endometrial regeneration and increases obstetric complications in subsequent pregnancies, including abnormal placentation (placenta accreta spectrum) and preterm delivery. Severity is visible at a glance. Use this illustration for reproductive endocrinology and infertility teaching, gynecology modules on uterine factor infertility, and surgical education covering hysteroscopic adhesiolysis and postoperative prevention strategies (barrier gels, balloon stents, estrogen priming). It also fits patient-facing counseling materials and review articles discussing intrauterine adhesions, cervical canal stenosis, and differential diagnosis of amenorrhea after uterine instrumentation.
