What Are The Causes of Recurrent Miscarriage?<\/strong><\/a><\/p>\n <\/p>\n
In most cases, the cause of the loss is unknown, but recurrent miscarriages can be due to:<\/span><\/p>\n <\/p>\n
\u2022 <\/span>Implantation defects of the ovum already fertilized in the uterus<\/strong>.<\/span><\/p>\n <\/p>\n
\u2022 <\/span>Chromosomal abnormalities of the fetus<\/strong>. In most cases, chromosomal abnormalities occur by chance. However, in some cases, they happen because the father or mother has a problem with the chromosomes. They also occur more frequently as maternal age increases.<\/span><\/p>\n <\/p>\n
\u2022 <\/span>Alterations in the shape of the uterus<\/strong> such as incompetence of the cervix, congenital anomalies of the uterus, adhesions (scars) in the uterine cavity, fibroids, polyps, etc. In these cases, abortions are caused by a decrease in the uterus’ ability to adapt to pregnancy, by associated incompetence of the cervix, or by abnormal vascularization (blood supply) or innervation.<\/span><\/p>\n <\/p>\n
\u2022 <\/span>Autoimmune diseases of the mother<\/strong>. In autoimmune diseases, the body’s defenses to fight infection also attack healthy tissues such as the fetus. In recurrent pregnancies, the relationship with the antiphospholipid syndrome should always be highlighted.<\/span><\/p>\n <\/p>\n
\u2022 <\/span>Other maternal illnesses<\/strong> such as diabetes, thyroid diseases, endometriosis, blood clotting disorders or hormonal problems (luteal phase failure, polycystic ovary, etc.).<\/span><\/p>\n <\/p>\n
\u2022 <\/span>Infections.<\/strong> They are rare causes of repeat miscarriages; the infectious agents most associated with this complication are Mycoplasma hominins, Ureaplasma urealyticum, and Listeria monocytogenes, among others.<\/span><\/p>\n <\/p>\n
