Oligomenorrhea is infrequent or scant menstruation. A cause of oligomenorrhea is failure to ovulate. Therefore if the woman is not ovulating, conception is not going to happen. A second cause of oligomenorrhea is failure of the uterine lining to develop during the proliferative phase of the menstrual cycle. In this case, if ovulation and conception occurred, the fertilized egg would have a difficult time implanting and establishing an adequate vascular bed to establish a placenta and circulation to nourish and maintain a pregnancy.
