Miscarriages are one of the most frustrating things that can occur in infertility patients. Miscarriages can occur in any woman. They are more common in women attempting to conceive by infertility treatments or who just have a history of infertility. Miscarriages are much more common in couples undergoing infertility treatments than in those who have never had a history of infertility.
The causes for miscarriages are multiple. They can be due to genetic causes, either in the eggs or the sperm or just in the embryos. They can also be due to anatomical causes like fibroid tumors of the uterus, endometriosis, uterine septum or any other uterine abnormalities, either from birth or developed. They can also be due to autoimmune causes in which a woman rejects the developing embryo, or in cases of abnormal clotting factors that cause infarcts or decreased blood supply to developing embryos and fetuses.
There are many causes for recurrent pregnancy loss. Recurrent pregnancy loss is defined as two or three miscarriages that occur in a woman over time, usually consecutively. It is very important to get a good diagnostic evaluation for a miscarriage. That can be done by a board certified reproductive endocrinologist or a maternal fetal medicine specialist.
There are treatments for recurrent pregnancy loss. In many cases where women or couples believe the case is absolutely hopeless, it is not. In many cases the next pregnancy is a perfectly normal pregnancy even without any medical intervention. Miscarriages can in many cases be treated and successful pregnancy achieved.
