12 Common Reasons for Repeated Pregnancy Failures

Comments are Off

Marriage is a wonderful thing, and pregnancy is the ultimate goal of most couples. But, sadly, many partners do not get such prosperity and have to face repeated failure to conceive. This is called miscarriage in medical terms. When miscarriage occurs again and again, it can lead to stress. But, the good thing is that infertility specialists in Chandigarh and several other cities can help to overcome infertility-related issues. They use several advanced procedures like IVF and IUI to overcome non-conception and repeated miscarriages. 

By recognizing the main cause of the miscarriages, you can get the proper treatment and have successful miscarriages. 

Read on to know 12 critical causes of miscarriage:

Abnormalities In Chromosomes

Abnormalities in chromosomes are the most common cause of repeated pregnancy failures, as per the best infertility specialist. This can occur due to accidental damage or loss of genetic material during fertilization. Damage to a chromosome may result in an abnormal number of cells, which leads to early abortion. If a couple has a history of miscarriages and wants to get pregnant again, they should consider repeating their efforts with in vitro fertilization (IVF).

Incompetent Cervix & Uterine Abnormalities

The uterine lining is composed of specialized cells called leukocytes, which are responsible for protecting the uterus from infection. A woman may get recurrent infections if these cells become defective during pregnancy or after delivery. Women with cervical insufficiency or endometriosis will be prone to repeated pregnancy failures because these conditions increase the risk of premature labor.

Maternal Illness

Maternal illness can also lead to repeated conception failures. If the woman is suffering from high blood pressure, heart disease, or diabetes, it may cause preeclampsia or eclampsia, resulting in miscarriage if not appropriately treated. Severe infections such as pneumonia can also cause miscarriages if not cured before conception occurs.

Immunological Disorders

Pregnancy failure may occur when an immunological disorder is present in the mother’s body. Immune system disorders such as thyroid disorder, diabetes, or other auto-immune diseases can cause multiple miscarriages, even in women with normal reproductive systems. In some cases, taking medications that suppress the immune system can lead to a higher risk of miscarriage by causing an imbalance in the immune system. Visit an infertility specialist near you in such a case.

Ectopic Pregnancy

An ectopic pregnancy is when the fertilized egg implants outside the womb (the fallopian tube), usually in the abdominal wall. The embryo doesn’t have room to grow and will die. If this happens early enough, it’s possible to have a miscarriage and not even know it happened.

An ectopic pregnancy is more likely if you’ve had one before or if you’ve had repeated miscarriages or stillbirths. It’s also more likely if you’re over 35 and smoke, drink heavily, or have high blood pressure.


A Trypanohematoma is a condition where there are blood clots in your placenta (the organ that connects your baby to your womb). It can lead to symptoms such as bleeding between periods, anemia, and fatigue. This ailment can be caused by an infection or by using certain medicines during pregnancy, such as certain antibiotics or hormones called progestogens (such as progesterone). Trypanohematomas are rare but may be severe if left untreated.


PCOS (polycystic ovary syndrome) is a common cause of recurrent pregnancy failure. This condition occurs when multiple hormonal imbalances result in irregular periods, excessive hair growth and acne on the face and body, and infertility.

PCOS is caused by problems with insulin production and/or insulin sensitivity. The body’s natural ability to regulate hormones becomes impaired, leading to higher than normal testosterone levels in women with PCOS, as well as irregular or absent menstrual cycles or excessive hair growth on their faces and bodies.

Thyroid Problems & Diabetes

According to top-rated infertility specialists, some women tend to miscarry because of thyroid problems. These include hypothyroidism (low thyroid function), hyperthyroidism (overactive thyroid), and hypothyroidism with goiter (enlarged thyroid gland).

Poor Lifestyle

Poor lifestyle habits like smoking, alcohol consumption, overeating, and neglecting body hygiene can affect fertility in many ways- including frequent conception.

Malnutrition During Pregnancy

 A woman who does not eat properly during her pregnancy may be affected by malnutrition and hence suffer from poor health during her pregnancy, which could lead to miscarriage.

Blood Clotting Disorder

Blood clots and pregnancy are a dangerous combination. If you have a blood clotting disorder and you become pregnant; in that case, you may be at risk for developing a condition called preeclampsia, which is a severe medical condition that can cause high blood pressure, fluid retention, and protein in the urine. This condition can lead to premature labor or even death of the mother if not taken seriously. Talk to your infertility specialist about possible treatments for your specific condition.

Natural Killer Cells

Natural killer cells are part of the immune system and have been shown to play an essential role in protecting against cancer and other diseases. Researchers believe sufficient levels of natural killer cells may be necessary for fetal development, growth, and maternal health during pregnancy. Low levels of natural killer cells during pregnancy could affect how well your baby responds to medications or infections later in life.

These are some of the major causes that may prevent you from being pregnant. Also, infertility specialists recommend planning a pregnancy in the young years of life because aging also increases the odds of miscarriage.
