Understanding Recurrent Pregnancy Loss
Recurrent pregnancy loss (RPL), defined as two or more consecutive miscarriages, places a tremendous psychological and physical strain on a couple. Dr. Heather Huddleston, MD, a reproductive medicine specialist, emphasizes that this condition requires a thorough and systematic evaluation to identify potential underlying causes. The journey to overcome recurrent pregnancy loss begins with a comprehensive diagnostic workup, as the causes are multiple and varied. Dr. Anton Titov, MD, notes that seeking a medical second opinion can be a crucial first step for couples to ensure their diagnosis is correct and complete, providing confidence before embarking on a treatment path.
Antiphospholipid Antibody Syndrome
A significant immunological cause of recurrent pregnancy loss is antiphospholipid antibody syndrome (APS). Dr. Heather Huddleston, MD, explains that this syndrome involves antibodies that can attack the placenta and disrupt implantation, leading to miscarriage. Research indicates that APS is a factor in approximately 15% to 18% of couples experiencing recurrent pregnancy loss. Treatment typically involves medications like low-dose aspirin or heparin to thin the blood and prevent clots, which can significantly improve the chances of a successful pregnancy.
Anatomic Uterine Issues
Physical abnormalities within the uterus are another important category of causes for repeat miscarriage. These can include congenital conditions like a septate uterus or acquired issues such as fibroids or scar tissue (Asherman's syndrome) that disrupt the environment needed for an embryo to implant and grow. Dr. Huddleston would include a detailed assessment of uterine anatomy, often via a saline sonogram or hysteroscopy, in her diagnostic workup. Correcting these anatomic issues surgically can often create the optimal conditions for a viable pregnancy.
Genetic and Chromosomal Causes
Genetic factors are a frequent cause of miscarriage and can originate from both parents or the fetus itself. As Dr. Heather Huddleston, MD, describes, a balanced chromosomal translocation in one parent is a key finding. While the parent is healthy, this can lead to embryos with unbalanced chromosomes that are not viable. Furthermore, advanced maternal age is a major risk factor for fetal aneuploidy, such as trisomy, where an embryo has three copies of a chromosome instead of two. Dr. Heather Huddleston, MD, notes that genetic problems in the fetus itself may explain up to 70% of sporadic pregnancy losses in women over 35.
Hormonal and Other Factors
Hormonal imbalances, particularly thyroid disorders like hypothyroidism, are well-established contributors to recurrent pregnancy loss. Proper endocrine function is critical for maintaining a pregnancy, and treating these imbalances is a fundamental part of therapy. Dr. Huddleston also points to thrombophilias, which are genetic mutations that cause a predisposition to form blood clots. These clotting disorders can impair blood flow to the placenta, especially leading to second-trimester pregnancy loss, and are another critical element of the diagnostic puzzle.
Diagnosis and the Role of Medical Second Opinion
Given the complexity of recurrent pregnancy loss, a detailed and multi-faceted workup is essential. Dr. Anton Titov, MD, highlights the immense value of a medical second opinion in this process. This second look can confirm that all possible causes—immunological, anatomical, genetic, hormonal, and thrombophilic—have been thoroughly investigated. For nearly half of all couples, no cause is found, a situation termed unexplained recurrent miscarriage. Even in these cases, a second opinion provides reassurance that the evaluation was exhaustive and helps couples feel confident in moving forward with empirical treatment or continued trying.
Treatment and Hope for the Future
Treatment for recurrent pregnancy loss is tailored to the specific cause identified. For many, getting pregnant after multiple miscarriages is possible with targeted interventions like blood thinners for APS, surgery for uterine issues, or IVF with preimplantation genetic testing (PGT) to select chromosomally normal embryos. Dr. Heather Huddleston, MD, offers a message of hope, stating that with persistence, many couples will ultimately achieve a successful pregnancy. She advises that even when the cause is a recurring genetic problem in the fetus, continued effort often leads to the conception of a healthy embryo, making perseverance a powerful tool in overcoming recurrent pregnancy loss.

Dr. Anton Titov, MD: Causes and treatment of recurrent pregnancy loss is reviewed by a leading fertility expert. What causes repeat miscarriage? How can a couple conceive after multiple miscarriages? How to overcome recurrent pregnancy loss?
Recurrent pregnancy loss causes and treatment includes therapy for the cause of RPL. Medical second opinion for recurrent early pregnancy loss treatment helps to choose the right approach.
Antiphospholipid antibodies and genetic causes are a frequent cause of miscarriage. Recurrent pregnancy loss often results in multiple miscarriages. In such a situation, a medical second opinion can help the couple.
Unexplained recurrent miscarriage treatment should start with getting a specialist medical second opinion. A detailed workup is needed to find the possible cause of miscarriages. Getting pregnant after multiple miscarriages is possible.
Recurrent pregnancy loss causes are multiple. Sometimes the genetic chromosome problems are in the fetus itself. A successful pregnancy after multiple miscarriages is possible with the use of IVF and modern reproductive technologies.
Dr. Anton Titov, MD: Video interview with a leading expert in fertility treatment and reproductive medicine. Medical second opinion confirms that the recurrent miscarriage diagnosis is correct and complete. It also confirms that treatment for recurrent pregnancy loss is required.
Medical second opinion helps to choose the best treatment for recurrent pregnancy loss and habitual miscarriage. Get a medical second opinion on multiple miscarriages and recurrent pregnancy loss causes. Be confident that your treatment is the best.
Dr. Anton Titov, MD: Another situation is when a woman gets pregnant and then repeatedly loses the pregnancy. It's a tremendous psychological pressure on the couple, but it's also a physical strain.
What are some of the causes of recurrent pregnancy loss? Online medical second opinion on infertility.
Dr. Heather Huddleston, MD: There are a variety of things that can cause recurrent pregnancy loss. There are several things I would look for. Sometimes a couple has had two or three miscarriages in a row.
Possible causes of recurrent pregnancy loss could be antiphospholipid antibody syndrome. This is a syndrome where antibodies directed potentially against the placenta can impact implantation. We think that about 15% to 18% of couples with recurrent pregnancy loss have antiphospholipid antibody syndrome.
I would also look for anatomic issues in the uterus. I would look for genetic problems, for example, a chromosomal translocation. This is a genetic finding that we look for in both the male and female partner.
Also, hormonal issues such as an abnormal thyroid or hypothyroidism can cause recurrent pregnancy loss. There is evidence that abnormalities that cause people to clot more easily can also cause unexplained pregnancy loss.
Genetic mutations that lead to increased blood clotting can potentially be causes of miscarriage, particularly second trimester pregnancy loss. So those are all things that we would look for.
Unfortunately, about half the time we don't find a cause. Some of the unexplained pregnancy loss may be caused by problems that we just don't know how to identify. I tell this to my patients always upfront.
Maybe in people who are having pregnancy losses, we are picking up the genetic problems in the fetus itself. We think that at least with sporadic pregnancy loss, genetic problems in the fetus can explain about 70% of sporadic pregnancy losses in women over 35.
In these situations of pregnancy loss, the actual pregnancy itself had an abnormal genotype. It is generally a trisomy, three of one of the chromosomes, which resulted and led to a pregnancy that can't really develop past a certain point.
The good news with that particular scenario is that if people continue to try and try to get pregnant, there is a very good chance that they will be successful. But it will just take that kind of persistence to overcome recurrent pregnancy loss.
