Suspensory ligament of clitoris

The suspensory ligament of the clitoris is a fibrous band at the deep fascial level that extends from the pubic symphysis to the deep fascia of the clitoris, anchoring the clitoris to the pubic symphysis. By virtue of this connection, the pubic symphysis supports the clitoris.

It consists of three distinct layers:

1. Superficial Layer: This layer originates from the anterior abdominal wall and is an extension of the fascia superficialis of the abdomen. It is composed mainly of loosely organized elastic fibers, fibroblasts, and a few loosely organized collagen fibers.[1]

2. Intermediate Layer: Also originating from the anterior abdominal wall, this layer extends through the abdominal aponeurosis to enclose the body of the clitoris and sends lateral extensions to the labia majora. Histologically, it consists primarily of well-organized collagen fibers and fibroblasts.[1]

3. Deep Layer: This shorter layer extends from the pubic symphysis to the knee of the clitoris and connects the two crura to the pubic symphysis. It is almost exclusively composed of very well-organized collagen fibers.[1]
