Tubal occlusion is a cause of infertility because an ovulated egg is unable to be fertilized by sperm or to reach the endometrial cavity. If both tubes are blocked, then in vitro f ...

Dysfunctional Uterine Bleeding Causes Ovulatory DUB (not associated with anovulation) is less common than anovulatory DUB, and the bleeding, though abnormally heavy, is usually regular.
