Functional endometrial disorders are irregular uterine bleeding that occurs in the absence of recognizable pelvic pathology, general medical disease, or pregnancy. It reflects a disruption in the normal cyclic pattern of ovulatory hormonal stimulation to the endometrial lining.
Functional endometrial disorders include:
- Anovulatory cycle
- Inadequate luteal phase
